190-564: Emperor Constantine , through the Council of Nicaea in 325, attempted to unite Christianity and establish a single, imperially approved version of the faith. Ironically, his efforts were the cause of the deep divisions created by the disputes after Nicaea. These disagreements divided the Church into various factions for over 55 years, from the time before the First Council of Nicaea in 325 until after

380-507: A Christian, he waited to be baptised on his deathbed, believing that the baptism would release him of any sins he committed in the course of carrying out his policies while emperor. He supported the Church financially, built basilicas, granted privileges to clergy (such as exemption from certain taxes), promoted Christians to high office, and returned property confiscated during the long period of persecution. His most famous building projects include

570-544: A collection of panegyrics from the late 3rd and early 4th centuries, provides valuable information on the politics and ideology of the tetrarchic period and the early life of Constantine. Contemporary architecture—such as the Arch of Constantine in Rome and palaces in Gamzigrad and Córdoba — epigraphic remains, and the coinage of the era complement the literary sources. Constantine

760-525: A grand adventus in the city which was met with jubilation. Maxentius' body was fished out of the Tiber and decapitated, and his head was paraded through the streets for all to see. After the ceremonies, the disembodied head was sent to Carthage, and Carthage offered no further resistance. Unlike his predecessors, Constantine neglected to make the trip to the Capitoline Hill and perform customary sacrifices at

950-541: A helmet emblazoned with the Chi Rho , and coins issued at Siscia in 317/318 repeat the image. The figure was otherwise rare and is uncommon in imperial iconography and propaganda before the 320s. It was not completely unknown, however, being an abbreviation of the Greek word chrēston (good), having previously appeared on the coins of Ptolemy III Euergetes in the 3rd century BC. Following Constantine, centuries of Christians invoked

1140-553: A large donative pledge to any who would support him as emperor, most of Constantine's army remained loyal to their emperor, and Maximian was soon compelled to leave. When Constantine heard of the rebellion, he abandoned his campaign against the Franks and marched his army up the Rhine. At Cabillunum ( Chalon-sur-Saône ), he moved his troops onto waiting boats to row down the slow waters of the Saône to

1330-483: A long evening of drinking, Galerius granted the request. Constantine's later propaganda describes how he fled the court in the night, before Galerius could change his mind. He rode from post-house to post-house at high speed, hamstringing every horse in his wake. By the time Galerius awoke the following morning, Constantine had fled too far to be caught. Constantine joined his father in Gaul , at Bononia ( Boulogne ) before

1520-460: A military support, which Maxentius accepted. According to Eusebius, inter-regional travel became impossible, and there was military buildup everywhere. There was "not a place where people were not expecting the onset of hostilities every day". Constantine's advisers and generals cautioned against preemptive attack on Maxentius; even his soothsayers recommended against it, stating that the sacrifices had produced unfavourable omens. Constantine, with

1710-531: A palace complex in the northeastern part of the city. To the south of his palace, he ordered the construction of a large formal audience hall and a massive imperial bathhouse. He sponsored many building projects throughout Gaul during his tenure as emperor of the West, especially in Augustodunum ( Autun ) and Arelate ( Arles ). According to Lactantius, Constantine followed a tolerant policy towards Christianity, although he

1900-835: A period referred to as the Constantinian shift . This initiated the Christianization of the Roman Empire . Constantine is associated with the religiopolitical ideology known as Caesaropapism , which epitomizes the unity of church and state. He founded the city of Constantinople and made it the capital of the Empire, which remained so for over a millennium. Born in Naissus , in Dardania within Moesia Superior (now Niš , Serbia), Constantine

2090-596: A public order, that if someone should be discovered to have hidden a writing composed by Arius, and not to have immediately brought it forward and destroyed it by fire, his penalty shall be death. As soon as he is discovered in this offence, he shall be submitted for capital punishment. ... Ten years after the Council of Nicaea, Constantine the Great , who was himself later baptized by the Arian bishop Eusebius of Nicomedia in 337 AD, convened another gathering of church leaders at

2280-449: A result of a debilitating sickness taken in the winter of 304–305, announced his resignation. In a parallel ceremony in Milan , Maximian did the same. Lactantius states that Galerius manipulated the weakened Diocletian into resigning and forced him to accept Galerius' allies in the imperial succession. According to Lactantius, the crowd listening to Diocletian's resignation speech believed, until

2470-508: A revolting and horrifying sight." Galerius died soon after the edict's proclamation, destroying what little remained of the Tetrarchy. Maximinus mobilised against Licinius and seized Asia Minor . A hasty peace was signed on a boat in the middle of the Bosphorus . While Constantine toured Britain and Gaul, Maxentius prepared for war. He fortified northern Italy and strengthened his support in

2660-544: A spirit that left a deep impression on his followers, inspiring some to believe that he had some form of supernatural guidance, ignored all these cautions. Early in the spring of 312, Constantine crossed the Cottian Alps with a quarter of his army, a force numbering about 40,000. The first town his army encountered was Segusium ( Susa , Italy), a heavily fortified town that shut its gates to him. Constantine ordered his men to set fire to its gates and scale its walls. He took

2850-460: A temple to Aphrodite . Generations later there was the story that a divine vision led Constantine to this spot, and an angel no one else could see led him on a circuit of the new walls. The capital would often be compared to the 'old' Rome as Nova Roma Constantinopolitana , the "New Rome of Constantinople". Constantine was the first emperor to stop the persecution of Christians and to legalize Christianity, along with all other religions/cults in

3040-435: A tolerant and politically skilled man, Constantius advanced through the ranks, earning the governorship of Dalmatia from Emperor Diocletian, another of Aurelian's companions from Illyricum , in 284 or 285. Constantine's mother was Helena , a Greek woman of low social standing from Helenopolis of Bithynia . It is uncertain whether she was legally married to Constantius or merely his concubine . His main language

3230-536: A total dissimilarity between the Son and the Father. Arianism holds that the Son is distinct from the Father and therefore subordinate to him. The term Arian is derived from the name Arius; it was not what the followers of Arius' teachings called themselves, but rather a term used by outsiders . The nature of Arius's and his supporters' teachings were opposed to the theological doctrines held by Homoousian Christians regarding

3420-415: A year, rejected it. Constantine sent Galerius an official notice of Constantius' death and his own acclamation. Along with the notice, he included a portrait of himself in the robes of an augustus. The portrait was wreathed in bay . He requested recognition as heir to his father's throne and passed off responsibility for his unlawful ascension on his army, claiming they had "forced it upon him". Galerius

3610-484: Is called Logos only because of resemblance with the inner Logos of God. A verse from Proverbs was used for the creation of the Son: "The Lord created me at the beginning of his work." Therefore, the Son was rather the very first and the most perfect of God's creatures, and he was called "God" only by the Father's permission and power. The definition of "Son" is ambiguous as Arians have applied an adoptionist theology to defend

3800-502: Is called, 'like-in-essence,' there ought to be no mention of any of these at all, nor exposition of them in the Church, for this reason and for this consideration, that in divine Scripture nothing is written about them, and that they are above men's knowledge and above men's understanding; As debates raged in an attempt to come up with a new formula, three camps evolved among the opponents of the Nicene Creed. The first group mainly opposed

3990-627: Is my Rome ". Sirmium and Thessalonica were also considered. Eventually, however, Constantine decided to work on the Greek city of Byzantium , which offered the advantage of having already been extensively rebuilt on Roman patterns of urbanism during the preceding century by Septimius Severus and Caracalla , who had already acknowledged its strategic importance. The city was thus founded in 324, dedicated on 11 May 330 and renamed Constantinopolis ("Constantine's City" or Constantinople in English). Special commemorative coins were issued in 330 to honor

4180-579: Is no certainty about what theological and philosophical traditions formed his thought. The influence from the One of Neo-Platonism was widespread throughout the Eastern Roman Empire and this influenced Arius. Arius's basic premise is that only God is independent for his existence. Since the Son is dependent he must therefore be called a creature. Arians put forward a question for their belief: "Has God birthed Jesus willingly or unwillingly?" This question

4370-520: Is not known. His praenomen is variously given as Lucius , Marcus and Gaius . Whatever the case, praenomina had already disappeared from most public records by this time. He also adopted the name "Valerius", the nomen of emperor Diocletian , following his father's ascension as caesar . Constantine probably spent little time with his father who was an officer in the Roman army, part of Emperor Aurelian 's imperial bodyguard. Being described as

4560-420: Is one God (Gk. theos – θεός), the Father, from whom are all things and for whom we exist, and one Lord/Master ( kyrios – κύριος), Jesus Christ, through whom are all things and through whom we exist. The creed of Arian Ulfilas (c. 311–383), which concludes the above-mentioned letter by Auxentius, distinguishes God the Father ("unbegotten"), who is the only true God, from the Son of God ("only-begotten"); and

4750-463: Is one God of all, who is also God of our God; and in one Holy Spirit, the illuminating and sanctifying power, as Christ said after his resurrection to his apostles: "And behold, I send the promise of my Father upon you; but tarry ye in the city of Jerusalem, until ye be clothed with power from on high" and again "But ye shall receive power, when the Holy Ghost is come upon you"; Neither God nor Lord, but

4940-461: Is somewhat doubtful, the fact is that he seems to have been far less open in his support of Christianity than Constantine. Therefore, Licinius was prone to see the Church as a force more loyal to Constantine than to the Imperial system in general, as the explanation offered by the Church historian Sozomen . This dubious arrangement eventually became a challenge to Constantine in the West, climaxing in

5130-479: Is the Son of God , who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before time by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time. Arius' trinitarian theology, later given an extreme form by Aetius and his disciple Eunomius and called anomoean ('dissimilar'), asserts

5320-513: Is the anonymous Origo Constantini , a work of uncertain date which focuses on military and political events to the neglect of cultural and religious matters. Lactantius ' De mortibus persecutorum , a political Christian pamphlet on the reigns of Diocletian and the Tetrarchy , provides valuable but tendentious detail on Constantine's predecessors and early life. The ecclesiastical histories of Socrates , Sozomen , and Theodoret describe

5510-535: Is traditionally said that 318 bishops came to Nicaea to attend the council, though others suggest figures from 250-300. The vast majority of those bishops were from the East. Italy, Spain, Gaul, North Africa, Persia, and Scythia each sent one bishop. Pope Sylvester I , himself too aged to attend, sent two priests as his delegates. Arius himself attended the council as well as the young deacon Athanasius, who attended as an assistant to Alexander of Alexandria and who would become

5700-518: Is venerated as a saint in Eastern Christianity , and he did much to push Christianity towards the mainstream of Roman culture. The age of Constantine marked a distinct epoch in the history of the Roman Empire and a pivotal moment in the transition from classical antiquity to the Middle Ages . He built a new imperial residence in the city of Byzantium and renamed it New Rome , later adopting

5890-500: The Via Flaminia , allowing the weakness of Maxentius to draw his regime further into turmoil. Maxentius' support continued to weaken: at chariot races on 27 October, the crowd openly taunted Maxentius, shouting that Constantine was invincible. Maxentius, no longer certain that he would emerge from a siege victorious, built a temporary boat bridge across the Tiber in preparation for a field battle against Constantine. On 28 October 312,

Theodosius had just been baptized, by bishop Acholius of Thessalonica, during a severe illness, as was common in the early Christian world. In February he and Gratian had published an edict that all their subjects should profess

6270-506: The Church of the Holy Sepulchre and Old St. Peter's Basilica . In constructing the Old St. Peter's Basilica, Constantine went to great lengths to erect the basilica on top of St. Peter 's resting place, so much so that it even affected the design of the basilica, including the challenge of erecting it on the hill where St. Peter rested, making its complete construction time over 30 years from

He played an influential role in the proclamation of the Edict of Milan in 313, which declared tolerance for Christianity in the Roman Empire. He convoked the First Council of Nicaea in 325 which produced the statement of Christian belief known as the Nicene Creed . The Church of the Holy Sepulchre was built on his orders at

6650-584: The First Council of Constantinople in 381. There was no formal schism . Inside the Roman Empire, the Trinitarian faction ultimately gained the upper hand through the Edict of Thessalonica , issued on 27 February AD 380, which made Nicene Christology the state religion of the Roman Empire , and through strict enforcement of that edict. However, outside the Roman Empire, Arianism and other forms of Unitarianism continued to be preached for some time (without

6840-723: The First Synod of Tyre in AD 335, they brought accusations against Athanasius , now bishop of Alexandria, the primary opponent of Arius. After this, Constantine had Athanasius banished since he considered him an impediment to reconciliation. In the same year, the Synod of Jerusalem under Constantine's direction readmitted Arius to communion in 336. Arius died on the way to this event in Constantinople. Some scholars suggest that Arius may have been poisoned by his opponents. Eusebius and Theognis remained in

7030-568: The Jews . The apparent resurgence of Arianism after Nicaea was more an anti-Nicene reaction exploited by Arian sympathizers than a pro-Arian development. By the end of the 4th century it had surrendered its remaining ground to Trinitarianism . In Western Europe, Arianism, which had been taught by Ulfilas , the Arian missionary to the Germanic tribes, was dominant among the Goths , Langobards and Vandals . By

However, he did visit the Senatorial Curia Julia , and he promised to restore its ancestral privileges and give it a secure role in his reformed government; there would be no revenge against Maxentius' supporters. In response, the Senate decreed him "title of the first name", which meant that his name would be listed first in all official documents, and they acclaimed him as "the greatest augustus". He issued decrees returning property that

His reputation flourished during the lifetime of his children and for centuries after his reign. The medieval church held him up as a paragon of virtue, while secular rulers invoked him as a prototype, a point of reference, and the symbol of imperial legitimacy and identity. At

7980-526: The fall of the Western Roman Empire . The antipopes Felix II and Ursinus were Arian, and Pope Liberius was forced to sign the Arian Creed of Sirmium of 357 although the letter says he willingly agreed with Arianism. Such a deep controversy within the early Church during this period of its development could not have materialized without significant historical influences providing a basis for

8170-401: The "Homoian" party, exiling bishops and often using force. During this persecution many bishops were exiled to the other ends of the Roman Empire (e.g., Saint Hilary of Poitiers to the eastern provinces). These contacts and the common plight subsequently led to a rapprochement between the western supporters of the Nicene Creed and the homoousios and the eastern Semi-Arians. It was not until

8360-495: The 'see', or ecclesiastical jurisdiction. The Homoousians taught that the Son is of the same substance as the Father, i.e. both uncreated. The Sabellian form had been condemned as heresy in the 3rd century by Pope Calixtus. The Athanasian form would be declared orthodox at the Council of Constantinople in 383, and has become the basis of most of modern trinitarianism . According to the historian Socrates of Constantinople , Marcellus of Ancyra and Photinus taught "that Christ

8550-467: The Alexandrian diocese . By the time Bishop Alexander finally acted against his presbyter, Arius's doctrine had spread far beyond his own see; it had become a topic of discussion—and disturbance—for the entire Church. The Church was now a powerful force in the Roman world, with Constantine I having legalized it in 313 through the Edict of Milan . "Constantine desired that the church should contribute to

8740-590: The Arian Philostorgius also survive, though their biases are no less firm. The epitomes of Aurelius Victor ( De Caesaribus ), Eutropius ( Breviarium ), Festus ( Breviarium ), and the anonymous author of the Epitome de Caesaribus offer compressed secular political and military histories of the period. Although not Christian, the epitomes paint a favourable image of Constantine but omit reference to Constantine's religious policies. The Panegyrici Latini ,

8930-514: The Arian German kingdoms established in the collapsing Western Empire in the 5th century were entirely separate Arian and Nicene Churches with parallel hierarchies, each serving different sets of believers. The Germanic elites were Arians, and the Romance majority population was Nicene. The Arian Germanic tribes were generally tolerant towards Nicene Christians and other religious minorities, including

9120-497: The Arian doctrines. Arius had been a pupil of Lucian of Antioch at Lucian's private academy in Antioch and inherited from him a modified form of the teachings of Paul of Samosata . Arius taught that God the Father and the Son of God did not always exist together eternally. Emperor Constantine the Great summoned the First Council of Nicaea , which defined the dogmatic fundaments of Christianity; these definitions served to rebut

9310-781: The Bosphorus and appointed Martinian , his magister officiorum , as nominal augustus in the West, but Constantine next won the Battle of the Hellespont and finally the Battle of Chrysopolis on 18 September 324. Licinius and Martinian surrendered to Constantine at Nicomedia on the promise their lives would be spared: they were sent to live as private citizens in Thessalonica and Cappadocia respectively, but in 325 Constantine accused Licinius of plotting against him and had them both arrested and hanged; Licinius' son (the son of Constantine's half-sister)

9500-546: The Bosporus and invaded European territory. Licinius departed and eventually defeated Maximinus, gaining control over the entire eastern half of the Roman Empire. Relations between the two remaining emperors deteriorated, as Constantine suffered an assassination attempt at the hands of a character that Licinius wanted elevated to the rank of Caesar; Licinius, for his part, had Constantine's statues in Emona destroyed. In either 314 or 316,

His early support dissolved in the wake of heightened tax rates and depressed trade; riots broke out in Rome and Carthage ; and Domitius Alexander was able to briefly usurp his authority in Africa. By 312, he was a man barely tolerated, not one actively supported, even among Christian Italians. In

9880-400: The Church, since Arius's theology received widespread sympathy (or at least was not considered to be overly controversial) and could not be dismissed outright as individual heresy. Arianism had several different variants, including Eunomianism and Homoian Arianism . Homoian Arianism is associated with Acacius and Eudoxius . Homoian Arianism avoided the use of the word ousia to describe

10070-509: The Council of Nicaea been the head of the Arian party, who also was made the bishop of Constantinople. Constantius used his power to exile bishops adhering to the Nicene Creed, especially St Athanasius of Alexandria , who fled to Rome. In 355 Constantius became the sole Roman emperor and extended his pro-Arian policy toward the western provinces, frequently using force to push through his creed, even exiling Pope Liberius and installing Antipope Felix II . The Third Council of Sirmium in 357

10260-557: The Danube with a Sarmatian captive to drop at Galerius' feet. It is uncertain how much these tales can be trusted. Constantine recognised the implicit danger in remaining at Galerius' court, where he was held as a virtual hostage. His career depended on being rescued by his father in the West. Constantius was quick to intervene. In the late spring or early summer of 305, Constantius requested leave for his son to help him campaign in Britain. After

Licinius' defeat came to represent the defeat of a rival centre of pagan and Greek-speaking political activity in the East, as opposed to the Christian and Latin-speaking Rome, and it

10640-643: The East, from Nicomedia ( İzmit , Turkey). The division was merely pragmatic: the empire was called "indivisible" in official panegyric, and both emperors could move freely throughout the empire. In 288, Maximian appointed Constantius to serve as his praetorian prefect in Gaul . Constantius left Helena to marry Maximian's stepdaughter Theodora in 288 or 289. Diocletian divided the empire again in 293, appointing two caesars to rule over further subdivisions of East and West. Each would be subordinate to his respective augustus but would act with supreme authority in his assigned lands. This system would later be called

10830-532: The Emperor's favor, and when Constantine, who had been a catechumen much of his adult life, accepted baptism on his deathbed, it was from Eusebius of Nicomedia. The First Council of Nicaea did not end the controversy, as many bishops of the Eastern provinces disputed the homoousios , the central term of the Nicene Creed, as it had been used by Paul of Samosata , who had advocated a monarchianist Christology .

Constantine pursued successful campaigns against the tribes on the Roman frontiers —such as the Franks , the Alemanni , the Goths , and

11210-515: The Father and God the Son and God the Holy Spirit all being uncreated. According to the teaching of Arius, the preexistent Logos and thus the incarnate Jesus Christ was a begotten being; only the Son was directly begotten by God the Father, before ages, but was of a distinct, though similar, essence or substance from the Creator. His opponents argued that this would make Jesus less than God and that this

11400-410: The Father is a deity and is divine and the Son of God is not a deity but divine (I, the LORD, am Deity alone.) God the Father sent Jesus to earth for salvation of mankind. Ousia is essence or being, in Eastern Christianity , and is the aspect of God that is completely incomprehensible to mankind and human perception. It is all that subsists by itself and which has not its being in another, God

11590-436: The Father, ("unbegotten" God; Almighty God) always existing and who is the only true God. The Son of God, Jesus Christ, ("only-begotten god" ), was begotten before time began. The Holy Spirit is the illuminating and sanctifying power of God. 1 Corinthians 8:5–6 was cited as proof text : Indeed, even though there may be so-called gods in heaven or on earth—as in fact there are many gods and many lords/masters—yet for us there

11780-425: The Father, therefore the time obviously was when He was not, and hence He was a finite being." According to some accounts in the hagiography of Saint Nicholas , debate at the council became so heated that at one point, he slapped Arius in the face. The majority of the bishops at the council ultimately agreed upon a creed, known thereafter as the Nicene Creed formulated at the first council of Nicaea. It included

11970-421: The Father. The Heteroousians (" dissimilar substance ") won the victory over the other two views in an initial debate. However, Constantius was not willing to accept this outcome either. He intervened and banished Aëtius; one of the leading proponents of the " dissimilar substance " view. After this, the council, including Maris and Eudoxius, agreed to a fourth view, namely the homoian (" like the Father ") view that

In 320, Licinius allegedly reneged on the religious freedom promised by the Edict of Milan and began to oppress Christians anew, generally without bloodshed, but resorting to confiscations and sacking of Christian office-holders. Although this characterization of Licinius as anti-Christian

12350-503: The Goths to Arianism was strengthened by later events; the conversion of Goths led to a widespread diffusion of Arianism among other Germanic tribes as well ( Vandals , Langobards , Svevi , and Burgundians ). When the Germanic peoples entered the provinces of the Western Roman Empire and began founding their own kingdoms there, most of them were Arian Christians. The conflict in the 4th century had seen Arian and Nicene factions struggling for control of Western Europe. In contrast, among

12540-431: The Great Constantine I ( Latin : Flavius Valerius Constantinus ; 27 February c.  272  – 22 May 337), also known as Constantine the Great , was a Roman emperor from AD 306 to 337 and the first Roman emperor to convert to Christianity . He played a pivotal role in elevating the status of Christianity in Rome, decriminalizing Christian practice and ceasing Christian persecution in

12730-447: The Holy Spirit, the illuminating and sanctifying power, which is neither God the Father nor the Lord Jesus Christ: I, Ulfila, bishop and confessor, have always so believed, and in this, the one true faith, I make the journey to my Lord; I believe in only one God the Father, the unbegotten and invisible, and in his only-begotten Son, our Lord/Master and God, the designer and maker of all creation, having none other like him. Therefore, there

In 308, he raided the territory of the Bructeri and made a bridge across the Rhine at Colonia Agrippinensium ( Cologne ). In 310, he marched to the northern Rhine and fought the Franks. When not campaigning, he toured his lands advertising his benevolence and supporting

13110-471: The Nicaean Creed—Arius himself, the deacon Euzoios, and the Libyan bishops Theonas of Marmarica and Secundus of Ptolemais —and also the bishops who signed the creed but refused to join in condemnation of Arius, Eusebius of Nicomedia and Theognis of Nicaea . The emperor also ordered all copies of the Thalia , the book in which Arius had expressed his teachings, to be burned . However, there is no evidence that his son and ultimate successor, Constantius II , who

13300-509: The Nicene terminology and preferred the term homoiousios (alike in substance) to the Nicene homoousios , while they rejected Arius and his teaching and accepted the equality and co-eternality of the persons of the Trinity. Because of this centrist position, and despite their rejection of Arius, they were called "Semi-Arians" by their opponents. The second group also avoided invoking the name of Arius, but in large part followed Arius's teachings and, in another attempted compromise wording, described

13490-408: The Picts and securing his control in the northwestern dioceses. He completed the reconstruction of military bases begun under his father's rule, and he ordered the repair of the region's roadways. He then left for Augusta Treverorum ( Trier ) in Gaul, the Tetrarchic capital of the northwestern Roman Empire. The Franks learned of Constantine's acclamation and invaded Gaul across the lower Rhine over

13680-659: The Praetorian Guard and Imperial Horse Guard . The tombstones of the Imperial Horse Guard were ground up and used in a basilica on the Via Labicana , and their former base was redeveloped into the Lateran Basilica on 9 November 312—barely two weeks after Constantine captured the city. The Legio II Parthica was removed from Albano Laziale , and the remainder of Maxentius' armies were sent to do frontier duty on

13870-466: The Rhine. In the following years, Constantine gradually consolidated his military superiority over his rivals in the crumbling Tetrarchy. In 313, he met Licinius in Milan to secure their alliance by the marriage of Licinius and Constantine's half-sister Constantia. During this meeting, the emperors agreed on the so-called Edict of Milan , officially granting full tolerance to Christianity and all religions in

14060-581: The Roman Empire. In February 313, he met with Licinius in Milan and developed the Edict of Milan, which stated that Christians should be allowed to follow their faith without oppression. This removed penalties for professing Christianity, under which many had been martyred previously , and it returned confiscated Church property. The edict protected all religions from persecution, not only Christianity, allowing anyone to worship any deity that they chose. A similar edict had been issued in 311 by Galerius, senior emperor of

14250-420: The Son as being like ( homoios ) the Father. A third group explicitly called upon Arius and described the Son as unlike ( anhomoios ) the Father. Constantius wavered in his support between the first and the second party, while harshly persecuting the third. Epiphanius of Salamis labeled the party of Basil of Ancyra in 358 " Semi-Arianism ". This is considered unfair by Kelly who states that some members of

14440-438: The Son was " like the Father ". But Basil of Ancyra and his party, following a (Homoiousian) Creed of Antioch from 341, declared that the Son was of " similar substance " to the Father. The majority at Seleucia accepted the " similar substance " view and deposed the opposing party. Constantius did not accept this outcome and requested a third council, at Constantinople (359), of both the eastern and western bishops, to resolve

14630-456: The Son) was "same in being" or "same in essence" with God the Father. Arius stated: "If the Father begat the Son, then he who was begotten had a beginning in existence, and from this it follows there was a time when the Son was not." The ecumenical First Council of Nicaea of 325 declared Arianism to be a heresy. According to Everett Ferguson , "The great majority of Christians had no clear views about

14820-560: The Tetrarchy, which granted Christians the right to practise their religion but did not restore any property to them. The Edict of Milan included several clauses which stated that all confiscated churches would be returned, as well as other provisions for previously persecuted Christians. Some scholars think that Helena adopted Christianity as an adult, and according to Eusebius she was converted by Constantine, but other historians debate whether Constantine adopted his mother Helena's Christianity in his youth or whether he adopted it gradually over

15010-417: The Tetrarchy. Diocletian's first appointee for the office of Caesar was Constantius ; his second was Galerius , a native of Felix Romuliana . According to Lactantius , Galerius was a brutal, animalistic man. Although he shared the paganism of Rome's aristocracy, he seemed to them an alien figure, a semi-barbarian. On 1 March, Constantius was promoted to the office of Caesar, and dispatched to Gaul to fight

15200-535: The Veronese forces and Maxentius' praetorian prefect, was in a strong defensive position since the town was surrounded on three sides by the Adige . Constantine sent a small force north of the town in an attempt to cross the river unnoticed. Ruricius sent a large detachment to counter Constantine's expeditionary force but was defeated. Constantine's forces successfully surrounded the town and laid siege. Ruricius gave Constantine

15390-552: The beginning of the Renaissance , there were more critical appraisals of his reign with the rediscovery of anti-Constantinian sources. Trends in modern and recent scholarship have attempted to balance the extremes of previous scholarship. Constantine was a ruler of major importance and has always been a controversial figure. The fluctuations in his reputation reflect the nature of the ancient sources for his reign. These are abundant and detailed, but they have been strongly influenced by

15580-514: The bishop Alexander of Alexandria , when Arius formulated the following syllogism : "If the Father begat the Son, he that was begotten had a beginning of existence: hence it is that there was when the Son was not. It follows then of necessity that he had his existence from the non-existence". Bishop Alexander of Alexandria was criticised for his slow reaction against Arius. Like his predecessor, Dionysius, he has been charged with vacillation. According to Eusebius 's work, The Life of Constantine ,

15770-681: The blessing of the Empire), but it was eventually killed off. The modern Roman Catholic Church and the Eastern Orthodox Church , as well as most other modern Christian sects, have generally followed the Trinitarian formulation, though each has its own specific theology on the matter. The early history of the controversy must be pieced together from about 35 documents found in various sources. The Trinitarian historian Socrates of Constantinople reports that Arius first became controversial under

15960-418: The champion of the Nicene Creed and spend most of his life battling Arianism and other form of Unitarianism . Also there were Eusebius of Caesarea and Eusebius of Nicomedia . Before the main conclave convened, Hosius initially met with Alexander and his supporters at Nicomedia . The council was presided over by the emperor himself, who participated in and even led some of its discussions. Those who upheld

16150-429: The cipher of Christ. Having this sign (☧), his troops stood to arms." Eusebius describes a vision that Constantine had while marching at midday in which "he saw with his own eyes the trophy of a cross of light in the heavens, above the sun, and bearing the inscription, In Hoc Signo Vinces " ("In this sign thou shalt conquer"). In Eusebius's account, Constantine had a dream the following night in which Christ appeared with

16340-610: The claimed site of Jesus' tomb in Jerusalem and was deemed the holiest place in all of Christendom . The papal claim to temporal power in the High Middle Ages was based on the fabricated Donation of Constantine . He has historically been referred to as the "First Christian Emperor", but while he did favour the Christian Church, some modern scholars debate his beliefs and even his comprehension of Christianity. Nevertheless, he

16530-518: The co-reigns of Gratian and Theodosius that Arianism was effectively wiped out among the ruling class and elite of the Eastern Empire. Valens died in the Battle of Adrianople in 378 and was succeeded by Theodosius I , who adhered to the Nicene Creed. This allowed for settling the dispute. Theodosius's wife St Flacilla was instrumental in his campaign to end Arianism. Two days after Theodosius arrived in Constantinople, 24 November 380, he expelled

16720-413: The coinage of Constantine advertised Mars as his patron. From 310 on, Mars was replaced by Sol Invictus , a god conventionally identified with Apollo. There is little reason to believe that either the dynastic connection or the divine vision are anything other than fiction, but their proclamation strengthened Constantine's claims to legitimacy and increased his popularity among the citizens of Gaul. By

16910-529: The controversy had spread from Alexandria into almost all the African regions, and was considered a disturbance of the public order by the Roman Empire. Constantine the Great (Constantine I) sent two letters to Arius and Bishop Alexander, asking the religious leaders to stop the controversy. The ongoing controversy led to Constantine's oversight of the First Council of Nicaea. Arianism would not be contained within

17100-482: The course of his life. Constantine possibly retained the title of pontifex maximus which emperors bore as heads of the ancient Roman religion until Gratian renounced the title. According to Christian writers, Constantine was over 40 when he finally declared himself a Christian, making it clear that he owed his successes to the protection of the Christian High God alone. Despite these declarations of being

17290-456: The creation ex nihilo of Jesus from God. Arians do not believe in the traditional doctrine of the Trinity . The letter of the Arian bishop Auxentius of Durostorum regarding the Arian missionary Ulfilas gives a picture of Arian beliefs. The Arian Ulfilas, who was ordained a bishop by the Arian bishop Eusebius of Nicomedia and returned to his people to work as a missionary, believed: God,

17480-470: The date Constantine ordered it to be built. Arianism Arianism ( Koinē Greek : Ἀρειανισμός , Areianismós ) is a Christological doctrine considered heretical by all modern mainstream branches of Christianity. It is first attributed to Arius ( c.  AD 256–336 ), a Christian presbyter who preached and studied in Alexandria , Egypt . Arian theology holds that Jesus Christ

17670-412: The deaths of both Arius and Constantine. Though Arianism had spread, Athanasius and other Nicene Christian church leaders crusaded against Arian theology, and Arius was anathemised and condemned as a heretic once more at the ecumenical First Council of Constantinople of 381 (attended by 150 bishops). The Roman Emperors Constantius II (337–361) and Valens (364–378) were Arians or Semi-Arians , as

17860-430: The demotion and continued to style himself as augustus on his coinage, even as other members of the Tetrarchy referred to him as a caesar on theirs. Maximinus was frustrated that he had been passed over for promotion while the newcomer Licinius had been raised to the office of augustus and demanded that Galerius promote him. Galerius offered to call both Maximinus and Constantine "sons of the augusti", but neither accepted

18050-487: The earlier rupture in their relations, Maxentius was eager to present himself as his father's devoted son after his death. He began minting coins with his father's deified image, proclaiming his desire to avenge Maximian's death. Constantine initially presented the suicide as an unfortunate family tragedy. By 311, however, he was spreading another version. According to this, after Constantine had pardoned him, Maximian planned to murder Constantine in his sleep. Fausta learned of

18240-509: The eastern Mediterranean. By 325, the controversy had become significant enough that the Emperor Constantine called an assembly of bishops, the First Council of Nicaea , which condemned Arius's doctrine and formulated the original Nicene Creed of 325 . The Nicene Creed's central term, used to describe the relationship between the Father and the Son, is Homoousios ( Ancient Greek : ὁμοούσιος ), or Consubstantiality , meaning "of

18430-408: The eastern front by the spring of 303, in time to witness the beginnings of Diocletian's " Great Persecution ", the most severe persecution of Christians in Roman history. In late 302, Diocletian and Galerius sent a messenger to the oracle of Apollo at Didyma with an inquiry about Christians. Constantine could recall his presence at the palace when the messenger returned and Diocletian accepted

18620-501: The eastern provinces (against the Persians ) before being recalled in the west (in AD ;305) to fight alongside his father in the province of Britannia . After his father's death in 306, Constantine was proclaimed as augustus (emperor) by his army at Eboracum ( York , England). He eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become

18810-468: The ecclesiastic disputes of Constantine's later reign. Written during the reign of Theodosius II (r. 402–450), a century after Constantine's reign, these ecclesiastical historians obscure the events and theologies of the Constantinian period through misdirection, misrepresentation, and deliberate obscurity. The contemporary writings of the orthodox Christian Athanasius and the ecclesiastical history of

19000-400: The economy and the arts. His refusal to participate in the war increased his popularity among his people and strengthened his power base in the West. Maximian returned to Rome in the winter of 307–308 but soon fell out with his son. In early 308, after a failed attempt to usurp Maxentius' title, Maximian returned to Constantine's court. On 11 November 308, Galerius called a general council at

19190-518: The elder Emperor Maximian and needed a new source of legitimacy. In a speech delivered in Gaul on 25 July 310, the anonymous orator reveals a previously unknown dynastic connection to Claudius II , a 3rd-century emperor famed for defeating the Goths and restoring order to the empire. Breaking away from tetrarchic models, the speech emphasizes Constantine's ancestral prerogative to rule, rather than principles of imperial equality. The new ideology expressed in

19380-402: The emperor's traditional purple robes . Constantine accepted the decision, knowing that it would remove doubts as to his legitimacy. Constantine's share of the empire consisted of Britain, Gaul, and Spain, and he commanded one of the largest Roman armies which was stationed along the important Rhine frontier. He remained in Britain after his promotion to emperor, driving back the tribes of

19570-501: The emperor. However, Constantine soon found reason to suspect the sincerity of these three, for he later included them in the sentence pronounced on Arius. In 358, the emperor Constantius II requested two councils, one of the western bishops at Ariminum (now Rimini in Northern Italy ) and one of the eastern bishops at Nicomedia . In 359, the western council met at Ariminum. Ursacius of Singidunum and Valens of Mursa , following

19760-442: The empire. The document had special benefits for Christians, legalizing their religion and granting them restoration for all property seized during Diocletian's persecution. It repudiates past methods of religious coercion and used only general terms to refer to the divine sphere—"Divinity" and "Supreme Divinity", summa divinitas . The conference was cut short, however, when news reached Licinius that his rival Maximinus had crossed

19950-616: The event. The new city was protected by the relics of the True Cross , the Rod of Moses and other holy relics, though a cameo now at the Hermitage Museum also represented Constantine crowned by the tyche of the new city. The figures of old gods were either replaced or assimilated into a framework of Christian symbolism . Constantine built the new Church of the Holy Apostles on the site of

20140-557: The faith of the bishops of Rome and Alexandria (i.e., the Nicene faith), or be handed over for punishment for not doing so. Although much of the church hierarchy in the East had opposed the Nicene Creed in the decades leading up to Theodosius's accession, he managed to achieve unity on the basis of the Nicene Creed. In 381, at the Second Ecumenical Council in Constantinople, a group of mainly Eastern bishops assembled and accepted

20330-587: The faithful minister of Christ; not equal, but subject and obedient in all things to the Son. And I believe the Son to be subject and obedient in all things to God the Father. A letter from Arius (c. 250–336) to the Arian Eusebius of Nicomedia (died 341) states the core beliefs of the Arians: Some of them say that the Son is an eructation, others that he is a production, others that he is also unbegotten. These are impieties to which we cannot listen, even though

20520-402: The field bearing unfamiliar symbols on their standards and their shields. According to Lactantius "Constantine was directed in a dream to cause the heavenly sign to be delineated on the shields of his soldiers, and so to proceed to battle. He did as he had been commanded, and he marked on their shields the letter Χ, with a perpendicular line drawn through it and turned round thus at the top, being

20710-420: The first charge. His horse guards and praetorians initially held their position, but they broke under the force of a Constantinian cavalry charge; they also broke ranks and fled to the river. Maxentius rode with them and attempted to cross the bridge of boats ( Ponte Milvio ), but he was pushed into the Tiber and drowned by the mass of his fleeing soldiers. Constantine entered Rome on 29 October 312 and staged

20900-414: The great civil war of 324. Constantine's Christian eulogists present the war as a battle between Christianity and paganism; Licinius, aided by Gothic mercenaries, represented the past and ancient paganism, while Constantine and his Franks marched under the standard of the labarum . Outnumbered but fired by their zeal, Constantine's army emerged victorious in the Battle of Adrianople . Licinius fled across

21090-568: The group were virtually orthodox from the start but disliked the adjective homoousios while others had moved in that direction after the out-and-out Arians had come into the open. The debates among these groups resulted in numerous synods, among them the Council of Serdica in 343, the Fourth Council of Sirmium in 358 and the double Council of Rimini and Seleucia in 359, and no fewer than fourteen further creed formulas between 340 and 360, leading

21280-444: The heretics threaten us with a thousand deaths. But we say and believe and have taught, and do teach, that the Son is not unbegotten, nor in any way part of the unbegotten; and that he does not derive his subsistence from any matter; but that by his own will and counsel he has subsisted before time and before ages as perfect as God, only begotten and unchangeable, and that before he was begotten, or created, or purposed, or established, he

21470-537: The honours that he had granted to leaders of the Senate were also invalidated. Constantine also attempted to remove Maxentius' influence on Rome's urban landscape. All structures built by him were rededicated to Constantine, including the Temple of Romulus and the Basilica of Maxentius . At the focal point of the basilica, a stone statue was erected of Constantine holding the Christian labarum in its hand. Its inscription bore

21660-404: The imperial court's demands for universal persecution. On 23 February 303, Diocletian ordered the destruction of Nicomedia' s new church, condemned its scriptures to the flames, and had its treasures seized. In the months that followed, churches and scriptures were destroyed, Christians were deprived of official ranks, and priests were imprisoned. It is unlikely that Constantine played any role in

21850-403: The last moment, that Diocletian would choose Constantine and Maxentius (Maximian's son) as his successors. It was not to be: Constantius and Galerius were promoted to augusti , while Severus and Maximinus , Galerius' nephew, were appointed their caesars respectively. Constantine and Maxentius were ignored. Some of the ancient sources detail plots that Galerius made on Constantine's life in

22040-529: The man and his teaching, including the term homoousios , had been condemned by the Synods of Antioch in 269. Hence, after Constantine's death in 337, open dispute resumed again. Constantine's son Constantius II , who had become emperor of the eastern part of the Roman Empire , actually encouraged the Arians and set out to reverse the Nicene Creed. His advisor in these affairs was Eusebius of Nicomedia, who had already at

22230-518: The message which the statue illustrated: "By this sign, Constantine had freed Rome from the yoke of the tyrant." Constantine also sought to upstage Maxentius' achievements. For example, the Circus Maximus was redeveloped so that its seating capacity was 25 times larger than that of Maxentius' racing complex on the Via Appia . Maxentius' strongest military supporters were neutralised when he disbanded

22420-519: The middle of 310, Galerius had become too ill to involve himself in imperial politics. His final act survives: a letter to provincials posted in Nicomedia on 30 April 311, proclaiming an end to the persecutions, and the resumption of religious toleration. Eusebius maintains "divine providence [...] took action against the perpetrator of these crimes" and gives a graphic account of Galerius' demise: "Without warning suppurative inflammation broke out round

22610-408: The middle of his genitals, then a deep-seated fistula ulcer; these ate their way incurably into his innermost bowels. From them came a teeming indescribable mass of worms, and a sickening smell was given off, for the whole of his hulking body, thanks to over eating, had been transformed even before his illness into a huge lump of flabby fat, which then decomposed and presented those who came near it with

22800-455: The military city of Carnuntum ( Petronell-Carnuntum , Austria) to resolve the instability in the western provinces. In attendance were Diocletian, briefly returned from retirement, Galerius, and Maximian. Maximian was forced to abdicate again and Constantine was again demoted to caesar. Licinius , one of Galerius' old military companions, was appointed augustus in the western regions. The new system did not last long: Constantine refused to accept

22990-419: The miraculous or the supernatural when justifying or describing their warfare. Constantine deployed his own forces along the whole length of Maxentius' line. He ordered his cavalry to charge, and they broke Maxentius' cavalry. He then sent his infantry against Maxentius' infantry, pushing many into the Tiber where they were slaughtered and drowned. The battle was brief, and Maxentius' troops were broken before

23180-420: The months following Diocletian's abdication. They assert that Galerius assigned Constantine to lead an advance unit in a cavalry charge through a swamp on the middle Danube, made him enter into single combat with a lion, and attempted to kill him in hunts and wars. Constantine always emerged victorious: the lion emerged from the contest in a poorer condition than Constantine; Constantine returned to Nicomedia from

23370-532: The name Constantinople after himself, where it was located in modern Istanbul . It subsequently became the capital of the empire for more than a thousand years, the later Eastern Roman Empire often being referred to in English as the Byzantine Empire , a term never used by the Empire, invented by German historian Hieronymus Wolf . His more immediate political legacy was that he replaced Diocletian's Tetrarchy with

23560-635: The nature of the Trinity and the nature of Christ. There was a controversy between two interpretations of Jesus's divinity (Homoousianism and Arianism) based upon the theological orthodoxy of the time, one trinitarian and the other also a derivative of trinitarian orthodoxy, and each of them attempted to solve its respective theological dilemmas. Homoousianism was formally affirmed by the first two ecumenical councils ; since then, Arianism has been condemned as "the heresy or sect of Arius". Trinitarian (Homoousian) doctrines were vigorously upheld by Patriarch Athanasius of Alexandria , who insisted that Jesus (God

23750-494: The nature of the Trinity and they did not understand what was at stake in the issues that surrounded it." Arianism is also used to refer to other nontrinitarian theological systems of the 4th century, which regarded Jesus Christ —the Son of God, the Logos —as either a begotten creature of a similar or different substance to that of the Father, but not identical (as Homoiousian and Anomoeanism ) or as neither uncreated nor created in

23940-552: The new creed drafted at Sirmium (359), proposed that, " according to the scriptures ," the Son was " like the Father ." This is known as the Homoian view which held that the Bible does not reveal whether the Son is of the same substance as the Father and we, therefore, should not speculate about such things. This view is in opposition to the " of the same substance " (Homoousios) view of the Nicene Creed. The council, including some supporters of

24130-431: The new title. By the spring of 310, Galerius was referring to both men as augusti. In 310, a dispossessed Maximian rebelled against Constantine while Constantine was away campaigning against the Franks. Maximian had been sent south to Arles with a contingent of Constantine's army, in preparation for any attacks by Maxentius in southern Gaul. He announced that Constantine was dead and took up the imperial purple. In spite of

24320-426: The north Italian plain sent Constantine embassies of congratulation for his victory. He moved on to Milan, where he was met with open gates and jubilant rejoicing. Constantine rested his army in Milan until mid-summer 312, when he moved on to Brixia ( Brescia ). Brescia's army was easily dispersed, and Constantine quickly advanced to Verona where a large Maxentian force was camped. Ruricius Pompeianus , general of

24510-591: The north without achieving great success. Constantius had become severely sick over the course of his reign and died on 25 July 306 in Eboracum . Before dying, he declared his support for raising Constantine to the rank of full Augustus. The Alamannic king Chrocus , a barbarian taken into service under Constantius, then proclaimed Constantine as augustus. The troops loyal to Constantius' memory followed him in acclamation. Gaul and Britain quickly accepted his rule; Hispania , which had been in his father's domain for less than

24700-413: The notion that Christ was co-eternal and con-substantial with the Father were led by the young archdeacon Athanasius. Those who instead insisted that the Son of God came after God the Father in time and substance, were led by Arius the presbyter. For about two months, the two sides argued and debated, with each appealing to Scripture to justify their respective positions. Arius maintained that the Son of God

24890-522: The official propaganda of the period and are often one-sided; no contemporaneous histories or biographies dealing with his life and rule have survived. The nearest replacement is Eusebius 's Vita Constantini —a mixture of eulogy and hagiography written between 335 and circa 339 —that extols Constantine's moral and religious virtues. The Vita creates a contentiously positive image of Constantine, and modern historians have frequently challenged its reliability. The fullest secular life of Constantine

25080-562: The old family alliance between Maximian and Constantius and offer support to Maxentius' cause in Italy. Constantine accepted and married Fausta in Trier in summer 307. Constantine gave Maxentius his meagre support, offering Maxentius political recognition. Constantine remained aloof from the Italian conflict, however. Over the spring and summer of 307, he had left Gaul for Britain to avoid any involvement in

25270-452: The older creed, accepted this proposal. After the council, Pope Liberius condemned the creed of Ariminum, while his rival, Pope Felix II , supported it. An earthquake struck Nicomedia , and in 359 the eastern council met at Seleucia Isauria instead. The council was bitterly divided and procedurally irregular, and the two parties met separately and reached opposing decisions. Following the Homoian view, Acacius of Caesarea declared that

25460-485: The orator proclaims that Constantine experienced a divine vision of Apollo and Victory granting him laurel wreaths of health and a long reign. In the likeness of Apollo, Constantine recognised himself as the saving figure to whom would be granted "rule of the whole world", as the poet Virgil had once foretold. The oration's religious shift is paralleled by a similar shift in Constantine's coinage. In his early reign,

25650-681: The pagan observer Ammianus Marcellinus to comment sarcastically: "The highways were covered with galloping bishops." None of these attempts were acceptable to the defenders of Nicene orthodoxy; writing about the latter councils, Saint Jerome remarked that the world "awoke with a groan to find itself Arian." After Constantius's death in 361, his successor Julian , a devotee of Rome's pagan gods , declared that he would no longer attempt to favor one church faction over another, and allowed all exiled bishops to return; this resulted in further increasing dissension among Nicene Christians. The emperor Valens , however, revived Constantius's policy and supported

25840-540: The panegyrist the opportunity to comment favourably on the similarities between father and son, and Eusebius remarked that Constantine was a "renewal, as it were, in his own person, of his father's life and reign". Constantinian coinage, sculpture, and oratory also show a tendency for disdain towards the "barbarians" beyond the frontiers. He minted a coin issue after his victory over the Alemanni which depicts weeping and begging Alemannic tribesmen, "the Alemanni conquered" beneath

26030-412: The persecution. In his later writings, he attempted to present himself as an opponent of Diocletian's "sanguinary edicts" against the "Worshippers of God", but nothing indicates that he opposed it effectively at the time. Although no contemporary Christian challenged Constantine for his inaction during the persecutions, it remained a political liability throughout his life. On 1 May 305, Diocletian, as

26220-440: The phrase "Romans' rejoicing". There was little sympathy for these enemies; as his panegyrist declared, "It is a stupid clemency that spares the conquered foe." Following Galerius' recognition of Constantine as caesar, Constantine's portrait was brought to Rome, as was customary. Maxentius mocked the portrait's subject as the son of a harlot and lamented his own powerlessness. Maxentius, envious of Constantine's authority, seized

26410-475: The plot and warned Constantine, who put a eunuch in his own place in bed. Maximian was apprehended when he killed the eunuch and was offered suicide, which he accepted. Along with using propaganda, Constantine instituted a damnatio memoriae on Maximian, destroying all inscriptions referring to him and eliminating any public work bearing his image. The death of Maximian required a shift in Constantine's public image. He could no longer rely on his connection to

26600-439: The proto-orthodox won the previous disputes, due to the more accurate defining of orthodoxy , they were vanquished with their own weapons, ultimately being declared heretics, not because they would have fought against ideas regarded as theologically correct, but because their positions lacked the accuracy and refinement needed by the fusion of several contradictory theses accepted at the same time by later orthodox theologians. Of

26790-440: The questions posed by Arians. Since Arius was not a bishop, he was not allowed to sit on the council, and it was Eusebius of Nicomedia who spoke for him and the position he represented. All the bishops who were there were in agreement with the major theological points of the proto-orthodoxy , since at that time all other forms of Christianity "had by this time already been displaced, suppressed, reformed, or destroyed". Although

26980-488: The quicker waters of the Rhone . He disembarked at Lugdunum ( Lyon ). Maximian fled to Massilia ( Marseille ), a town better able to withstand a long siege than Arles. It made little difference, however, as loyal citizens opened the rear gates to Constantine. Maximian was captured and reproved for his crimes. Constantine granted some clemency but strongly encouraged his suicide. In July 310, Maximian hanged himself . In spite of

27170-512: The rebels Carausius and Allectus . In spite of meritocratic overtones, the Tetrarchy retained vestiges of hereditary privilege, and Constantine became the prime candidate for future appointment as Caesar as soon as his father took the position. Constantine went to the court of Diocletian, where he lived as his father's heir presumptive . Constantine received a formal education at Diocletian's court, where he learned Latin literature, Greek, and philosophy. The cultural environment in Nicomedia

27360-463: The regional First Synod of Tyre in 335 (attended by 310 bishops), to address various charges mounted against Athanasius by his detractors, such as "murder, illegal taxation, sorcery, and treason", following his refusal to readmit Arius into fellowship. Athanasius was exiled to Trier (in modern Germany ) following his conviction at Tyre of conspiracy, and Arius was, effectively, exonerated. Athanasius eventually returned to Alexandria in 346, after

27550-495: The relation of Father to Son, and described these as "like" each other. Hanson lists twelve creeds that reflect the Homoian faith: In 321, Arius was denounced by a synod at Alexandria for teaching a heterodox view of the relationship of Jesus to God the Father. Because Arius and his followers had great influence in the schools of Alexandria—counterparts to modern universities or seminaries—their theological views spread, especially in

27740-491: The roughly 300 bishops in attendance at the Council of Nicaea , two bishops did not sign the Nicene Creed that condemned Arianism. Constantine the Great also ordered a penalty of death for those who refused to surrender the Arian writings: In addition, if any writing composed by Arius should be found, it should be handed over to the flames, so that not only will the wickedness of his teaching be obliterated, but nothing will be left even to remind anyone of him. And I hereby make

27930-451: The same heavenly sign and told him to make an army standard in the form of the labarum . Eusebius is vague about when and where these events took place, but it enters his narrative before the war begins against Maxentius. He describes the sign as Chi (Χ) traversed by Rho (Ρ) to form ☧, representing the first two letters of the Greek word ΧΡΙΣΤΟΣ (Christos). A medallion was issued at Ticinum in 315 which shows Constantine wearing

28120-542: The same substance" or "of one being" (the Athanasian Creed is less often used but is a more overtly anti-Arian statement on the Trinity). The focus of the Council of Nicaea was the nature of the Son of God and his precise relationship to God the Father (see Paul of Samosata and the Synods of Antioch ). Arius taught that Jesus Christ was divine/holy and was sent to earth for the salvation of mankind but that Jesus Christ

28310-633: The same time, Acacius also deposed and banished the Anomoean deacon Aëtius. In 360, Acacius appointed Eudoxius of Antioch to replace Macedonius and Athanasius of Ancyra to replace Basil, as well as Onesimus of Nicomedia to replace Cecropius, who had died in the earthquake at Nicomedia. In 361, Constantius died and Julian became sole Roman emperor. Julian demanded the restoration of several pagan temples which Christians had seized or destroyed. According to Philostorgius , pagans killed George of Laodicea , bishop of Alexandria , allowing Athanasius to reclaim

28500-550: The same type of war he had waged against Severus and Galerius: he occupied Rome and prepared for a siege. He still controlled Rome's Praetorian Guard , was well-stocked with African grain, and was surrounded on all sides by the seemingly impregnable Aurelian Walls . He ordered all bridges across the Tiber cut, reportedly on the counsel of the gods, and left the rest of central Italy undefended; Constantine secured that region's support without challenge. Constantine progressed slowly along

28690-535: The scriptures," without speaking of substance. Several members of the other schools, such as Hosius of Cordoba and Aëtius, also accepted certain Homoian formulae. The Heteroousians taught that the Son is of a different substance from the Father, i.e. created. Arius had taught this early in the controversy, and Aëtius would teach the later Anomoean form. Many critics of the "Nicene" Creed cannot be clearly associated with one school, often due to lack of sources, or due to contradictions between sources. Constantine

28880-477: The sense other beings are created (as in semi-Arianism ). Some early Christians that were counted among Orthodoxy denied the eternal generation of the Son, seeing the Son as being begotten in time. These include Tertullian and Justin Martyr . Tertullian is considered a pre-Arian. Among the other church fathers, Origen was accused of Arianism for using terms like "second God", and Patriarch Dionysius of Alexandria

29070-533: The sixth anniversary of his reign, he approached the keepers of the Sibylline Books for guidance. The keepers prophesied that, on that very day, "the enemy of the Romans" would die. Maxentius advanced north to meet Constantine in battle. Maxentius' forces were still twice the size of Constantine's, and he organised them in long lines facing the battle plain with their backs to the river. Constantine's army arrived on

29260-422: The slip and returned with a larger force to oppose Constantine. Constantine refused to let up on the siege and sent only a small force to oppose him. In the desperately fought encounter that followed, Ruricius was killed and his army destroyed. Verona surrendered soon afterwards, followed by Aquileia , Mutina ( Modena ), and Ravenna . The road to Rome was now wide open to Constantine. Maxentius prepared for

29450-461: The social and moral strength of the empire, religious dissension was a menace to the public welfare." Consequently, the emperor had taken a personal interest in several ecumenical issues, including the Donatist controversy in 316. He also wanted to bring an end to the Arian dispute. To this end, the emperor sent bishop Hosius of Corduba to investigate and, if possible, resolve the controversy. Hosius

29640-471: The sole ruler of the Roman Empire by 324. Upon his ascension, Constantine enacted numerous reforms to strengthen the empire. He restructured the government, separating civil and military authorities. To combat inflation, he introduced the solidus , a new gold coin that became the standard for Byzantine and European currencies for more than a thousand years. The Roman army was reorganised to consist of mobile units ( comitatenses ), often around

29830-434: The speech made Galerius and Maximian irrelevant to Constantine's right to rule. Indeed, the orator emphasizes ancestry to the exclusion of all other factors: "No chance agreement of men, nor some unexpected consequence of favour, made you emperor," the orator declares to Constantine. The oration also moves away from the religious ideology of the Tetrarchy, with its focus on twin dynasties of Jupiter and Hercules . Instead,

30020-406: The split at Seleucia. Acacius and Basil of Ancyra, respectively, again proposed the " like the Father " and " similar substance " views, as were explained at Seleucia. However, Maris of Chalcedon, Eudoxius of Antioch , and the deacons Aëtius of Antioch and Eunomius of Cyzicus proposed a third view which was similar to Arius' teachings, namely that the Son was of " a dissimilar substance " from

30210-660: The subject of the letter of Auxentius cited above) was sent as a missionary to the Gothic tribes across the Danube , a mission favored for political reasons by the Emperor Constantius II . The Homoians in the Danubian provinces played a major role in the conversion of the Goths to Arianism . Ulfilas's translation of the Bible into Gothic language and his initial success in converting

30400-568: The summer of 305. From Bononia, they crossed the English Channel to Britain and made their way to Eboracum ( York ), capital of the province of Britannia Secunda and home to a large military base. Constantine was able to spend a year in northern Britain at his father's side, campaigning against the Picts beyond Hadrian's Wall in the summer and autumn. Constantius' campaign, like that of Septimius Severus before it, probably advanced far into

30590-581: The summer of 311, Maxentius mobilised against Constantine while Licinius was occupied with affairs in the East. He declared war on Constantine, vowing to avenge his father's "murder". To prevent Maxentius from forming an alliance against him with Licinius, Constantine forged his own alliance with Licinius over the winter of 311–312 and offered him his sister Constantia in marriage. Maximinus considered Constantine's arrangement with Licinius an affront to his authority. In response, he sent ambassadors to Rome, offering political recognition to Maxentius in exchange for

30780-425: The theologians of the 19th century it was already obvious that in fact Arius and Alexander/Athanasius did not have much to quarrel about, the difference between their views was very small, and that the end of the fight was by no means clear during their quarrel, both Arius and Athanasius suffering a great deal for their own views. Arius was the father of Homoiousianism and Alexander the father of Homoousianism , which

30970-576: The title of emperor on 28 October 306. Galerius refused to recognize him but failed to unseat him. Severus was sent against Maxentius in April 307, but during the campaign, Severus' armies, previously under command of Maxentius' father Maximian, defected, and Severus was seized and imprisoned. Maximian, brought out of retirement by his son's rebellion, left for Gaul to confer with Constantine. He offered to marry his daughter Fausta to Constantine and elevate him to augustan rank. In return, Constantine would reaffirm

31160-667: The town quickly. Constantine ordered his troops not to loot the town and advanced into northern Italy. At the approach to the west of the important city of Augusta Taurinorum ( Turin , Italy), Constantine met a large force of heavily armed Maxentian cavalry. In the ensuing Battle of Turin Constantine's army encircled Maxentius' cavalry, flanked them with his own cavalry, and dismounted them with blows from his soldiers' iron-tipped clubs. Constantine's armies emerged victorious. Turin refused to give refuge to Maxentius' retreating forces, opening its gates to Constantine instead. Other cities of

31350-445: The two augusti fought against one another at the Battle of Cibalae , with Constantine being victorious. They clashed again at the Battle of Mardia in 317 and agreed to a settlement in which Constantine's sons Crispus and Constantine II , and Licinius' son Licinius Junior were made caesars . After this arrangement, Constantine ruled the dioceses of Pannonia and Macedonia and took residence at Sirmium , whence he could wage war on

31540-401: The winter of 306–307. He drove them back beyond the Rhine and captured kings Ascaric and Merogais ; the kings and their soldiers were fed to the beasts of Trier Amphitheater in the adventus (arrival) celebrations which followed. Constantine began a major expansion of Trier. He strengthened the circuit wall around the city with military towers and fortified gates, and he began building

31730-464: The word homoousios , meaning "consubstantial", or "same in essence", which was incompatible with Arius' beliefs. On June 19, 325, council and emperor issued a circular to the churches in and around Alexandria: Arius and two of his unyielding partisans (Theonas and Secundus) were deposed and exiled to Illyricum , while three other supporters— Theognis of Nicaea , Eusebius of Nicomedia and Maris of Chalcedon—affixed their signatures solely out of deference to

31920-487: Was Latin , and during his public speeches he needed Greek translators. In April 286, Diocletian declared Maximian , another colleague from Illyricum, his co-emperor. Each emperor would have his own court, his own military and administrative faculties, and each would rule with a separate praetorian prefect as chief lieutenant. Maximian ruled in the West, from his capitals at Mediolanum ( Milan , Italy) or Augusta Treverorum ( Trier , Germany), while Diocletian ruled in

32110-406: Was a Creature, made from nothing; and that he was God's First Production, before all ages. And he argued that everything else was created through the Son. Thus, said Arius, only the Son was directly created and begotten of God; furthermore, there was a time that He had no existence. He was capable of His own free will, said Arius, and thus "were He in the truest sense a son, He must have come after

32300-553: Was a Semi-Arian Christian, was exiled. Although he was committed to maintaining what the Great Church had defined at Nicaea, Constantine was also bent on pacifying the situation and eventually became more lenient toward those condemned and exiled at the council. First, he allowed Eusebius of Nicomedia, who was a protégé of his sister, and Theognis to return once they had signed an ambiguous statement of faith. The two, and other friends of Arius, worked for Arius's rehabilitation. At

32490-413: Was a mere man." Their opponents associated the teachings of Marcellus of Ancyra and Photinus of Sirmium with those of Sabellius and Paul of Samosata , which had been widely rejected before the controversy. The Homoiousian school taught that the Son is of a similar substance to the Father but not the same. The Homoians taught that the Son is similar to the Father, either "in all things" or "according to

32680-473: Was already agreed to at Ariminum. They made only minor modifications to the Ariminum creed. After the Council of Constantinople, the homoian bishop Acacius deposed and banished several homoiousian bishops, including Macedonius I of Constantinople , Basil, Eustathius, Eleusius of Cyzicus , Dracontius of Pergamum , Neonas of Seleucia , Sophronius of Pompeiopolis , Elpidius of Satala and Cyril of Jerusalem . At

32870-502: Was armed with an open letter from the Emperor: "Wherefore let each one of you, showing consideration for the other, listen to the impartial exhortation of your fellow-servant." As the debate continued to rage despite Hosius' efforts, Constantine in AD 325 took an unprecedented step: he called an ecumenical council at Nicaea composed of church prelates from all parts of the empire to resolve this issue, possibly at Hosius' recommendation. It

33060-564: Was born on 27 February, c.  AD 272 in the city of Naissus , a time where the unity of the Empire was threatened by the breakaway wars of the Palmyrene Empire . The city—which is modern day Niš in Serbia —was located in Dardania within Moesia Superior . His father was Flavius Constantius an Illyrian who was born in the same region, and a native of the province of Moesia. His original full name, as well as that of his father,

33250-424: Was championed by Athanasius. For those theologians it was clear that Arius, Alexander and Athanasius were far from a true doctrine of Trinity, which developed later, historically speaking. Guido M. Berndt and Roland Steinacher state clearly that the beliefs of Arius were acceptable ("not especially unusual") to a huge number of orthodox clergy; this is the reason why such a major conflict was able to develop inside

33440-765: Was denounced at Rome for saying that Son is a work and creature of God. However, the Subordinationism of Origen is not identical to Arianism, and it has been generally viewed as closer to the Nicene-Constantinopolitan view. Controversy over Arianism arose in the late 3rd century and persisted throughout most of the 4th century. It involved most church members—from simple believers, priests, and monks to bishops, emperors, and members of Rome's imperial family. Two Roman emperors, Constantius II and Valens , became Arians or Semi-Arians , as did prominent Gothic , Vandal , and Lombard warlords both before and after

33630-505: Was heretical. Much of the distinction between the differing factions was over the phrasing that Christ expressed in the New Testament to express submission to God the Father. The theological term for this submission is kenosis . This ecumenical council declared that Jesus Christ was true God, co-eternal and consubstantial (i.e., of the same substance) with God the Father. Constantine is believed to have exiled those who refused to accept

33820-404: Was killed in 326. Thus Constantine became the sole emperor of the Roman Empire. Diocletian had chosen Nicomedia in the East as his capital during the Tetrarchy —not far from Byzantium, well situated to defend Thrace, Asia, and Egypt, all of which had required his military attention. Constantine had recognised the shift of the empire from the remote and depopulated West to the richer cities of

34010-439: Was lost under Maxentius, recalling political exiles, and releasing Maxentius' imprisoned opponents. An extensive propaganda campaign followed, during which Maxentius' image was purged from all public places. He was written up as a "tyrant" and set against an idealised image of Constantine the "liberator". Eusebius is the best representative of this strand of Constantinian propaganda. Maxentius' rescripts were declared invalid, and

34200-637: Was nonetheless a prominent member of the court: he fought for Diocletian and Galerius in Asia and served in a variety of tribunates ; he campaigned against barbarians on the Danube in 296 and fought the Persians under Diocletian in Syria in 297, as well as under Galerius in Mesopotamia in 298–299. By late 305, he had become a tribune of the first order, a tribunus ordinis primi . Constantine had returned to Nicomedia from

34390-408: Was not equal to God the Father (infinite, primordial origin) in rank and that God the Father and the Son of God were not equal to the Holy Spirit. Under Arianism, Christ was instead not consubstantial with God the Father since both the Father and the Son under Arius were made of "like" essence or being (see homoiousia ) but not of the same essence or being (see homoousia ). In the Arian view, God

34580-528: Was not yet a Christian. He probably judged it a more sensible policy than open persecution and a way to distinguish himself from the "great persecutor" Galerius. He decreed a formal end to persecution and returned to Christians all that they had lost during them. Constantine was largely untried and had a hint of illegitimacy about him; he relied on his father's reputation in his early propaganda, which gave as much coverage to his father's deeds as to his. His military skill and building projects, however, soon gave

34770-406: Was not. For he was not unbegotten. We are persecuted because we say that the Son has a beginning but that God is without beginning. Principally, the dispute between Trinitarianism and Arianism was about: For Constantine, these were minor theological points that stood in the way of uniting the Empire, but for the theologians, it was of huge importance; for them, it was a matter of salvation. For

34960-469: Was open, fluid, and socially mobile; in it, Constantine could mix with intellectuals both pagan and Christian. He may have attended the lectures of Lactantius, a Christian scholar of Latin in the city. Because Diocletian did not completely trust Constantius—none of the Tetrarchs fully trusted their colleagues—Constantine was held as something of a hostage, a tool to ensure Constantius' best behavior. Constantine

35150-413: Was proposed that a new Eastern capital should represent the integration of the East into the Roman Empire as a whole, as a centre of learning, prosperity, and cultural preservation for the whole of the Eastern Roman Empire. Among the various locations proposed for this alternative capital, Constantine appears to have toyed earlier with Serdica (present-day Sofia ), as he was reported saying that " Serdica

35340-445: Was put into a fury by the message; he almost set the portrait and messenger on fire. His advisers calmed him and argued that outright denial of Constantine's claims would mean certain war. Galerius was compelled to compromise: he granted Constantine the title "caesar" rather than "augustus" (the latter office went to Severus instead). Wishing to make it clear that he alone gave Constantine legitimacy, Galerius personally sent Constantine

35530-540: Was the first King of Italy , Odoacer (433?–493), and the Lombards were also Arians or Semi-Arians until the 7th century. The ruling elite of Visigothic Spain was Arian until 589. Many Goths adopted Arian beliefs upon their conversion to Christianity. The Vandals actively spread Arianism in North Africa. Little of Arius's own work survives except in quotations selected for polemical purposes by his opponents, and there

35720-599: Was the high point of Arianism. The Seventh Arian Confession (Second Sirmium Confession) held that both homoousios (of one substance) and homoiousios (of similar substance) were unbiblical and that the Father is greater than the Son. (This confession was later known as the Blasphemy of Sirmium.) But since many persons are disturbed by questions concerning what is called in Latin substantia , but in Greek ousia , that is, to make it understood more exactly, as to 'coessential,' or what

35910-459: Was the son of Flavius Constantius , a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy . His mother, Helena , was a Greek woman of low birth, probably from Asia Minor in modern Turkey . Later canonised as a saint , she is traditionally credited for the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius . He began his career by campaigning in

36100-460: Was used to argue that Jesus is dependent for his existence since Jesus exists only because God wants him to be. Arianism taught that the Logos was a divine being begotten by God the Father before the creation of the world, made him a medium through whom everything else was created, and that the Son of God is subordinate to God the Father. The Logos is an inner attribute of God that is wisdom, while Jesus
