The Dolev–Yao model , named after its authors Danny Dolev and Andrew Yao , is a formal model used to prove properties of interactive cryptographic protocols.

93-447: The network is represented by a set of abstract machines that can exchange messages. These messages consist of formal terms. These terms reveal some of the internal structure of the messages, but some parts will hopefully remain opaque to the adversary. The adversary in this model can overhear, intercept, and synthesize any message and is only limited by the constraints of the cryptographic methods used. In other words: "the attacker carries

186-619: A "deity" and various cultures have conceptualized their deities differently. Monotheistic religions typically refer to their god in masculine terms, while other religions refer to their deities in a variety of ways—male, female, hermaphroditic , or genderless. Many cultures—including the ancient Mesopotamians , Egyptians , Greeks , Romans , and Germanic peoples —have personified natural phenomena , variously as either deliberate causes or effects. Some Avestan and Vedic deities were viewed as ethical concepts. In Indian religions , deities have been envisioned as manifesting within

279-448: A Cartesian sense, would mean the omnipotent being is above logic, a view supported by René Descartes . He issues this idea in his Meditations on First Philosophy . This view is called universal possibilism. According to Hindu philosophy the essence of Brahman can never be understood or known since Brahman is beyond both existence and non-existence, transcending and including time, causation and space, and thus can never be known in

372-422: A creator God or transcendental absolute principle ( monistic theologies), which manifests immanently in nature. Henotheism accepts the existence of more than one deity, but considers all deities as equivalent representations or aspects of the same divine principle, the highest. Monolatry is the belief that many deities exist, but that only one of these deities may be validly worshipped. Monotheism

465-569: A deity as "a being with powers greater than those of ordinary humans, but who interacts with humans, positively or negatively, in ways that carry humans to new levels of consciousness , beyond the grounded preoccupations of ordinary life". Religions can be categorized by how many deities they worship. Monotheistic religions accept only one deity (predominantly referred to as " God "), whereas polytheistic religions accept multiple deities. Henotheistic religions accept one supreme deity without denying other deities, considering them as aspects of

558-535: A deity is or could be omnipotent, or take the view that, by choosing to create creatures with free will , a deity has chosen to limit divine omnipotence. In Conservative and Reform Judaism , and some movements within Protestant Christianity , including open theism , deities are said to act in the world through persuasion, and not by coercion (this is a matter of choice—a deity could act miraculously, and perhaps on occasion does so—while for process theism it

651-569: A few of them, particularly Dumuzid , Geshtinanna , and Gugalanna were said to have either died or visited the underworld. Both male and female deities were widely venerated. In the Sumerian pantheon, deities had multiple functions, which included presiding over procreation, rains, irrigation, agriculture, destiny, and justice. The gods were fed, clothed, entertained, and worshipped to prevent natural catastrophes as well as to prevent social chaos such as pillaging, rape, or atrocities. Many of

744-505: A modified view of omnipotence was also articulated by Alfred North Whitehead in the early 20th century and expanded upon by Charles Hartshorne. Hartshorne proceeded within the context of the theological system known as process theology. Thomas Jay Oord argues that omnipotence dies a death of a thousand philosophical qualifications. To make any sense, the word must undergo various logical, ontological, mathematical, theological, and existential qualifications so that it loses specificity. In

837-644: A pantheon of deities, the chief of whom was the god El , who ruled alongside his consort Asherah and their seventy sons . Baal was the god of storm, rain, vegetation and fertility, while his consort Anat was the goddess of war and Astarte , the West Semitic equivalent to Ishtar , was the goddess of love. The people of the Kingdoms of Israel and Judah originally believed in these deities, alongside their own national god Yahweh. El later became syncretized with Yahweh , who took over El's role as

930-399: A part of normal development. D. W. Winnicott took a more positive view of a belief in early omnipotence, seeing it as essential to the child's well-being; and "good-enough" mothering as essential to enable the child to "cope with the immense shock of loss of omnipotence" —as opposed to whatever "prematurely forces it out of its narcissistic universe". Some monotheists reject the view that

1023-492: A prehistoric female deity. A number of probable representations of deities have been discovered at 'Ain Ghazal and the works of art uncovered at Çatalhöyük reveal references to what is probably a complex mythology. Diverse African cultures developed theology and concepts of deities over their history. In Nigeria and neighboring West African countries , for example, two prominent deities (locally called Òrìṣà ) are found in

1116-609: A presiding deity, who inspired social rituals, special trading markets and community festivals. A deity with aspects similar to Kulkulkan in the Aztec culture has been called Quetzalcoatl . However, states Timothy Insoll, the Aztec ideas of deity remain poorly understood. What has been assumed is based on what was constructed by Christian missionaries . The deity concept was likely more complex than these historical records. In Aztec culture , there were hundred of deities, but many were henotheistic incarnations of one another (similar to

1209-469: A single entity has given rise to considerable theological debate, prominently including the problem of evil , the question of why such a deity would permit the existence of evil. It is accepted in philosophy and science that omnipotence can never be effectively understood. The word omnipotence derives from the Latin prefix omni -, meaning "all", and the word potens , meaning "potent" or "powerful". Thus

1302-407: A specific and flawed personality. They were not omnipotent and could be injured in some circumstances. Greek deities led to cults, were used politically and inspired votive offerings for favors such as bountiful crops, healthy family, victory in war, or peace for a loved one recently deceased. The Roman pantheon had numerous deities, both Greek and non-Greek. The more famed deities, found in

1395-506: A world so constituted rather than by another. Indeed, the production of secondary causes, capable of accomplishing certain effects, requires greater power than the direct accomplishment of these same effects. On the other hand, even though no creature existed, God's power would not be barren, for "creatures are not an end to God." Regarding the deity's power, medieval theologians contended that there are certain things that even an omnipotent deity cannot do. The statement "a deity can do anything"

1488-497: Is necessarily true is one whose negation is self-contradictory. It is sometimes objected that this aspect of omnipotence involves the contradiction that God cannot do all that He can do; but the argument is sophistical; it is no contradiction to assert that God can realize whatever is possible, but that no number of actualized possibilities exhausts His power. Omnipotence is perfect power, free from all mere potentiality. Hence, although God does not bring into external being all that He

1581-420: Is a frank acknowledgement of a relic of the old megalomania of infancy". Similarly Freud concluded that "we can detect an element of megalomania in most other forms of paranoic disorder. We are justified in assuming that this megalomania is essentially of an infantile nature and that, as development proceeds, it is sacrificed to social considerations". Freud saw megalomania as an obstacle to psychoanalysis . In

1674-424: Is a matter of necessity—creatures have inherent powers that a deity cannot, even in principle, override). Deities are manifested in the world through inspiration and the creation of possibility, not necessarily by miracles or violations of the laws of nature. Process theology rejects unlimited omnipotence on a philosophical basis, arguing that omnipotence as classically understood would be less than perfect, and

1767-459: Is able to accomplish, His power must not be understood as passing through successive stages before its effect is accomplished. The activity of God is simple and eternal, without evolution or change. The transition from possibility to actuality or from act to potentiality, occurs only in creatures. When it is said that God can or could do a thing, the terms are not to be understood in the sense in which they are applied to created causes, but as conveying

1860-451: Is derived from Proto-Germanic *guthan , from PIE *ghut- , which means "that which is invoked". Guth in the Irish language means "voice". The term *ghut- is also the source of Old Church Slavonic zovo ("to call"), Sanskrit huta- ("invoked", an epithet of Indra ), from the root *gheu(e)- ("to call, invoke."), An alternate etymology for the term "god" comes from

1953-469: Is impossible to conclusively identify any prehistoric figurines as representations of any kind of deities, let alone goddesses. Nonetheless, it is possible to evaluate ancient representations on a case-by-case basis and rate them on how likely they are to represent deities. The Venus of Willendorf , a female figurine found in Europe and dated to about 25,000 BCE has been interpreted by some as an exemplar of

2046-412: Is intrinsically possible, not to do the intrinsically impossible. You may attribute miracles to him, but not nonsense. This is no limit to his power. If you choose to say 'God can give a creature free will and at the same time withhold free will from it,' you have not succeeded in saying anything about God: meaningless combinations of words do not suddenly acquire meaning simply because we prefix to them

2139-424: Is itself partly active, then there must be some resistance, however slight, to the "absolute" power, and how can power which is resisted be absolute? The argument can be stated as follows: For example, although someone might control a lump of jelly-pudding almost completely, the inability of that pudding to stage any resistance renders that person's power rather unimpressive. Power can only be said to be great if it

2232-504: Is masculine, and the related feminine equivalent is devi . Etymologically, the cognates of Devi are Latin dea and Greek thea . In Old Persian , daiva- means " demon , evil god", while in Sanskrit it means the opposite, referring to the "heavenly, divine, terrestrial things of high excellence, exalted, shining ones". The closely linked term " god " refers to "supreme being, deity", according to Douglas Harper, and

2325-414: Is not a power but a defect or infirmity. In response to questions of a deity performing impossibilities, e.g. making square circles, Aquinas says that "everything that does not imply a contradiction in terms, is numbered amongst those possible things, in respect of which God is called omnipotent: whereas whatever implies contradiction does not come within the scope of divine omnipotence, because it cannot have

2418-402: Is only sensible with an assumed suppressed clause, "that implies the perfection of true power". This standard scholastic answer allows that acts of creatures such as walking can be performed by humans but not by a deity. Rather than an advantage in power, human acts such as walking, sitting, or giving birth were possible only because of a defect in human power. The capacity to sin , for example,

2511-527: Is over something that has defenses and its own agenda. If a deity's power is to be great, it must therefore be over beings that have at least some of their own defenses and agenda. Thus, if a deity does not have absolute power, it must therefore embody some of the characteristics of power, and some of the characteristics of persuasion. This view is known as dipolar theism . The most popular works espousing this point are from Harold Kushner (in Judaism). The need for

2604-405: Is simply power. From this premise, Charles Hartshorne argues further that: Power is influence, and perfect power is perfect influence ... power must be exercised upon something, at least if by power we mean influence, control; but the something controlled cannot be absolutely inert, since the merely passive, that which has no active tendency of its own, is nothing; yet if the something acted upon

2697-414: Is the belief that divinity pervades the universe, but that it also transcends the universe. Agnosticism is the position that it is impossible to know for certain whether a deity of any kind exists. Atheism is the non-belief in the existence of any deity. Scholars infer the probable existence of deities in the prehistoric period from inscriptions and prehistoric arts such as cave drawings , but it

2790-429: Is the belief that only one deity exists. A monotheistic deity, known as "God", is usually described as omnipotent , omnipresent , omniscient , omnibenevolent and eternal . However, not all deities have been regarded this way and an entity does not need to be almighty, omnipresent, omniscient, omnibenevolent or eternal to qualify as a deity. Deism is the belief that only one deity exists, who created

2883-456: Is the superstitious man who fears the gods, while the truly religious person venerates them as parents. Cicero, in his Academica , praised Varro for this and other insights. According to Varro, there have been three accounts of deities in the Roman society: the mythical account created by poets for theatre and entertainment, the civil account used by people for veneration as well as by the city, and

2976-453: Is therefore incompatible with the idea of a perfect deity. The idea is grounded in Plato's oft-overlooked statement that "being is power". My notion would be, that anything which possesses any sort of power to affect another, or to be affected by another, if only for a single moment, however trifling the cause and however slight the effect, has real existence; and I hold that the definition of being

3069-489: Is typically seen as male . In contrast, all ancient Indo-European cultures and mythologies recognized both masculine and feminine deities. There is no universally accepted consensus on what a deity is, and concepts of deities vary considerably across cultures. Huw Owen states that the term "deity or god or its equivalent in other languages" has a bewildering range of meanings and significance. It has ranged from "infinite transcendent being who created and lords over

3162-504: Is unclear what these sketches and paintings are and why they were made. Some engravings or sketches show animals, hunters or rituals. It was once common for archaeologists to interpret virtually every prehistoric female figurine as a representation of a single, primordial goddess, the ancestor of historically attested goddesses such as Inanna , Ishtar , Astarte , Cybele , and Aphrodite ; this approach has now generally been discredited. Modern archaeologists now generally recognize that it

3255-588: Is zoomorphic and is most often found in Middle Eastern archaeological remains depicted as a "snake-dragon" or a "human-animal hybrid". In Germanic languages , the terms cognate with ' god ' such as Old English : god and Old Norse : guð were originally neuter but became masculine, as in modern Germanic languages, after Christianisation due their use in referring to the Christian god . In Norse mythology , Æsir (singular áss or ǫ́ss ) are

3348-743: The Authorized King James Version of the Bible , as well as several other versions, in Revelation 19:6 it is stated "the Lord God omnipotent reigneth" ( Ancient Greek : παντοκράτωρ , romanized :  pantokrator , "all-mighty"). Thomas Jay Oord argues that omnipotence is not found in the Hebrew and Greek scriptures. The Hebrew words Shaddai (breasts) and Sabaoth (hosts) are wrongly translated as "God almighty" or "divine omnipotence". Pantokrator,

3441-484: The Latin deitatem (nominative deitas ) or "divine nature", coined by Augustine of Hippo from deus ("god"). Deus is related through a common Proto-Indo-European (PIE) origin to *deiwos . This root yields the ancient Indian word Deva meaning "to gleam, a shining one", from *div- "to shine", as well as Greek dios " divine " and Zeus ; and Latin deus "god" ( Old Latin deivos ). Deva

3534-546: The Vanir went to war , according to the Nordic sources. The account in Ynglinga saga describes the Æsir–Vanir War ending in truce and ultimate reconciliation of the two into a single group of gods, after both sides chose peace, exchanged ambassadors (hostages), and intermarried. The Norse mythology describes the cooperation after the war, as well as differences between the Æsir and

3627-578: The Vanir which were considered scandalous by the other side. The goddess Freyja of the Vanir taught magic to the Æsir , while the two sides discover that while Æsir forbid mating between siblings , Vanir accepted such mating. Temples hosting images of Germanic gods (such as Thor , Odin and Freyr ), as well as pagan worship rituals, continued in Scandinavia into the 12th century, according to historical records. It has been proposed that over time, Christian equivalents were substituted for

3720-524: The Yoruba religion , namely the god Ogun and the goddess Osun . Ogun is the primordial masculine deity as well as the archdivinity and guardian of occupations such as tools making and use, metal working, hunting, war, protection and ascertaining equity and justice. Osun is an equally powerful primordial feminine deity and a multidimensional guardian of fertility, water, maternal, health, social relations, love and peace. Ogun and Osun traditions were brought into

3813-442: The avatar concept of Hinduism). Unlike Hinduism and other cultures, Aztec deities were usually not anthropomorphic, and were instead zoomorphic or hybrid icons associated with spirits, natural phenomena or forces. The Aztec deities were often represented through ceramic figurines, revered in home shrines. The Polynesian people developed a theology centered on numerous deities, with clusters of islands having different names for

3906-697: The Americas on slave ships . They were preserved by the Africans in their plantation communities, and their festivals continue to be observed. In Southern African cultures , a similar masculine-feminine deity combination has appeared in other forms, particularly as the Moon and Sun deities. One Southern African cosmology consists of Hieseba or Xuba (deity, god), Gaune (evil spirits) and Khuene (people). The Hieseba includes Nladiba (male, creator sky god) and Nladisara (females, Nladiba's two wives). The Sun (female) and

3999-723: The East Semitic Ishtar, became popular, with temples across Mesopotamia. The Mesopotamian mythology of the first millennium BCE treated Anšar (later Aššur ) and Kišar as primordial deities. Marduk was a significant god among the Babylonians. He rose from an obscure deity of the third millennium BCE to become one of the most important deities in the Mesopotamian pantheon of the first millennium BCE. The Babylonians worshipped Marduk as creator of heaven, earth and humankind, and as their national god . Marduk's iconography

4092-668: The Father , God the Son , and the Holy Spirit . The first person to describe the persons of the Trinity as homooúsios ([ὁμοούσιος] Error: {{Transliteration}}: transliteration text not Latin script ( help ) ; "of the same substance") was the Church Father Origen. Although most early Christian theologians (including Origen ) were Subordinationists , who believed that the Father was superior to

4185-651: The Germanic deities to help suppress paganism as part of the Christianisation of the Germanic peoples . Worship of the Germanic gods has been revived in the modern period as part of the new religious movement of Heathenry . The ancient Greeks revered both gods and goddesses. These continued to be revered through the early centuries of the common era, and many of the Greek deities inspired and were adopted as part of much larger pantheon of Roman deities. The Greek religion

4278-636: The Greek pantheon were the Twelve Olympians : Zeus, Hera , Poseidon , Athena , Apollo , Artemis , Aphrodite, Hermes , Demeter , Dionysus , Hephaestus , and Ares . Other important Greek deities included Hestia , Hades and Heracles . These deities later inspired the Dii Consentes galaxy of Roman deities. Besides the Olympians, the Greeks also worshipped various local deities. Among these were

4371-527: The Greek word in the New Testament and Septuagint often translated in English as "almighty", actually means "all-holding" rather than almighty or omnipotent. Oord offers an alternative view of divine power he calls "amipotence," which is the maximal power of God's uncontrolling love. Trying to develop a theory to explain, assign or reject omnipotence on grounds of logic has little merit, since being omnipotent, in

4464-543: The Inca people have corresponded to elements of nature. Of these, the most important ones have been Inti ( sun deity ) responsible for agricultural prosperity and as the father of the first Inca king, and Mama Qucha the goddess of the sea, lakes, rivers and waters. Inti in some mythologies is the son of Viracocha and Mama Qucha . Inca Sun deity festival Oh creator and Sun and Thunder, be forever copious, do not make us old, let all things be at peace, multiply

4557-482: The Moon (male) deities are viewed as offspring of Nladiba and two Nladisara . The Sun and Moon are viewed as manifestations of the supreme deity, and worship is timed and directed to them. In other African cultures the Sun is seen as male, while the Moon is female, both symbols of the godhead. In Zimbabwe , the supreme deity is androgynous with male-female aspects, envisioned as the giver of rain, treated simultaneously as

4650-509: The Proto-Germanic Gaut , which traces it to the PIE root *ghu-to- ("poured"), derived from the root *gheu- ("to pour, pour a libation "). The term *gheu- is also the source of the Greek khein "to pour". Originally the word "god" and its other Germanic cognates were neuter nouns but shifted to being generally masculine under the influence of Christianity in which the god

4743-629: The Son and the Son superior to the Holy Spirit, this belief was condemned as heretical by the First Council of Nicaea in the fourth century, which declared that all three persons of the Trinity are equal. Christians regard the universe as an element in God's actualization and the Holy Spirit is seen as the divine essence that is "the unity and relation of the Father and the Son". According to George Hunsinger,

4836-478: The Sumerian deities were patron guardians of city-states . The most important deities in the Sumerian pantheon were known as the Anunnaki , and included deities known as the "seven gods who decree": An , Enlil , Enki , Ninhursag , Nanna , Utu and Inanna . After the conquest of Sumer by Sargon of Akkad , many Sumerian deities were syncretized with East Semitic ones. The goddess Inanna, syncretized with

4929-516: The aspect of possibility. Hence it is better to say that such things cannot be done, than that God cannot do them. Nor is this contrary to the word of the angel, saying: 'No word shall be impossible with God.' For whatever implies a contradiction cannot be a word, because no intellect can possibly conceive such a thing." C. S. Lewis has adopted a scholastic position in the course of his work The Problem of Pain . Lewis follows Aquinas' view on contradiction: His Omnipotence means power to do all that

5022-474: The child lives in a sort of megalomania for a long period; he knows only one yardstick, and that is his own over-inflated ego ... megalomania, it must be understood, is normal in the very young child". Bergler was of the opinion that in later life "the activity of gambling in itself unconsciously activates the megalomania and grandiosity of childhood, reverting to the "fiction of omnipotence"". Heinz Kohut regarded "the narcissistic patient's "megalomania" as

5115-577: The dawn, for instance, is cognate to Indic Ushas , Roman Aurora and Latvian Auseklis . Zeus , the Greek king of gods, is cognate to Latin Iūpiter , Old German Ziu , and Indic Dyaus , with whom he shares similar mythologies. Other deities, such as Aphrodite , originated from the Near East . Greek deities varied locally, but many shared panhellenic themes, celebrated similar festivals, rites, and ritual grammar. The most important deities in

5208-505: The decryption function D x {\displaystyle D_{x}} . Their main properties are that their composition is the identity function ( D x E x = E x D x = 1 {\displaystyle D_{x}E_{x}=E_{x}D_{x}=1} ) and that an encrypted message E x ( M ) {\displaystyle E_{x}(M)} reveals nothing about M {\displaystyle M} . Unlike in

5301-399: The deity is a principle or reality such as the idea of "soul". The Upanishads of Hinduism, for example, characterize Atman (soul, self) as deva (deity), thereby asserting that the deva and eternal supreme principle ( Brahman ) is part of every living creature, that this soul is spiritual and divine, and that to realize self-knowledge is to know the supreme. Theism is the belief in

5394-549: The doctrine of the Trinity justifies worship in a Church, wherein Jesus Christ is deemed to be a full deity with the Christian cross as his icon. The theological examination of Jesus Christ, of divine grace in incarnation, his non-transferability and completeness has been a historic topic. For example, the Council of Chalcedon in 451 CE declared that in "one person Jesus Christ, fullness of deity and fullness of humanity are united,

5487-408: The existence of one or more deities. Polytheism is the belief in and worship of multiple deities, which are usually assembled into a pantheon of gods and goddesses , with accompanying rituals . In most polytheistic religions, the different gods and goddesses are representations of forces of nature or ancestral principles , and can be viewed either as autonomous or as aspects or emanations of

5580-459: The formation of an Egyptian state under the Pharaohs and their treatment as sacred kings who had exclusive rights to interact with the gods, in the later part of the 3rd millennium BCE. Through the early centuries of the common era, as Egyptians interacted and traded with neighboring cultures, foreign deities were adopted and venerated. The ancient Canaanites were polytheists who believed in

5673-472: The given assumptions about the attackers capabilities. Omnipotence Omnipotence is the quality of having unlimited power . Monotheistic religions generally attribute omnipotence only to the deity of their faith. In the monotheistic religious philosophy of Abrahamic religions , omnipotence is often listed as one of God 's characteristics, along with omniscience , omnipresence , and omnibenevolence . The presence of all these properties in

5766-791: The goat-legged god Pan (the guardian of shepherds and their flocks), Nymphs ( nature spirits associated with particular landforms), Naiads (who dwelled in springs), Dryads (who were spirits of the trees), Nereids (who inhabited the sea), river gods, satyrs (a class of lustful male nature spirits), and others. The dark powers of the underworld were represented by the Erinyes (or Furies), said to pursue those guilty of crimes against blood-relatives. The Greek deities, like those in many other Indo-European traditions, were anthropomorphic. Walter Burkert describes them as "persons, not abstractions, ideas or concepts". They had fantastic abilities and powers; each had some unique expertise and, in some aspects,

5859-858: The god of darkness and light and is called Mwari Shona . In the Lake Victoria region, the term for a deity is Lubaale , or alternatively Jok . Ancient Egyptian culture revered numerous deities. Egyptian records and inscriptions list the names of many whose nature is unknown and make vague references to other unnamed deities. Egyptologist James P. Allen estimates that more than 1,400 deities are named in Egyptian texts, whereas Christian Leitz offers an estimate of "thousands upon thousands" of Egyptian deities. Their terms for deities were nṯr (god), and feminine nṯrt (goddess); however, these terms may also have applied to any being – spirits and deceased human beings, but not demons – who in some way were outside

5952-501: The goddess Meretseger represented parts of the earth, and the god Sia represented the abstract powers of perception. Deities such as Ra and Osiris were associated with the judgement of the dead and their care during the afterlife. Major gods often had multiple roles and were involved in multiple phenomena. The first written evidence of deities are from early 3rd millennium BCE, likely emerging from prehistoric beliefs. However, deities became systematized and sophisticated after

6045-1036: The head of the pantheon, with Asherah as his divine consort and the "sons of El" as his offspring. During the later years of the Kingdom of Judah , a monolatristic faction rose to power insisting that only Yahweh was fit to be worshipped by the people of Judah. Monolatry became enforced during the reforms of King Josiah in 621 BCE. Finally, during the national crisis of the Babylonian captivity , some Judahites began to teach that deities aside from Yahweh were not just unfit to be worshipped, but did not exist. The "sons of El" were demoted from deities to angels . Ancient Mesopotamian culture in southern Iraq had numerous dingir (deities, gods and goddesses). Mesopotamian deities were almost exclusively anthropomorphic. They were thought to possess extraordinary powers and were often envisioned as being of tremendous physical size. They were generally immortal, but

6138-424: The idea of a Being, the range of Whose activity is limited only by His sovereign Will. Aquinas says that: Power is predicated of God not as something really distinct from His knowledge and will, but as differing from them logically; inasmuch as power implies a notion of a principle putting into execution what the will commands, and what knowledge directs, which three things in God are identified. Or we may say, that

6231-504: The imposition of Christianity during Spanish colonialism , the Inca people retained their original beliefs in deities through syncretism , where they overlay the Christian God and teachings over their original beliefs and practices. The male deity Inti became accepted as the Christian God, but the Andean rituals centered around Inca deities have been retained and continued thereafter into

6324-460: The knowledge or will of God, according as it is the effective principle, has the notion of power contained in it. Hence the consideration of the knowledge and will of God precedes the consideration of His power, as the cause precedes the operation and effect. The adaptation of means to ends in the universe does not argue, as John Stuart Mill would have it, that the power of the designer is limited, but only that God has willed to manifest his glory by

6417-430: The message." This omnipotence has been very difficult to model, and many threat models simplify it, as has been done for the attacker in ubiquitous computing . Cryptographic primitives are modeled by abstract operators. For example, asymmetric encryption for a user x {\displaystyle x} is represented by the encryption function E x {\displaystyle E_{x}} and

6510-640: The modern era by the Inca people. In Maya culture , Kukulkan has been the supreme creator deity , also revered as the god of reincarnation , water, fertility and wind. The Maya people built step pyramid temples to honor Kukulkan , aligning them to the Sun 's position on the spring equinox . Other deities found at Maya archaeological sites include Xib Chac —the benevolent male rain deity, and Ixchel —the benevolent female earth, weaving and pregnancy goddess. The Maya calendar had 18 months, each with 20 days (and five unlucky days of Uayeb ); each month had

6603-452: The mythologies and the 2nd millennium CE European arts, have been the anthropomorphic deities syncretized with the Greek deities. These include the six gods and six goddesses: Venus, Apollo, Mars, Diana, Minerva, Ceres, Vulcan, Juno, Mercury, Vesta, Neptune, Jupiter (Jove, Zeus); as well Bacchus, Pluto and Hercules. The non-Greek major deities include Janus, Fortuna, Vesta, Quirinus and Tellus (mother goddess, probably most ancient). Some of

6696-641: The natural account created by the philosophers. The best state is, adds Varro, where the civil theology combines the poetic mythical account with the philosopher's. The Roman deities continued to be revered in Europe through the era of Constantine, and past 313 CE when he issued the Edict of Toleration. The Inca culture has believed in Viracocha (also called Pachacutec ) as the creator deity . Viracocha has been an abstract deity to Inca culture, one who existed before he created space and time. All other deities of

Modern orthodox Christians believe that the Trinity is composed of three equal, cosubstantial persons: God

6882-467: The network) and responses (obtaining a message from the network). The symbolic nature of the Dolev–Yao model makes it more manageable than computational models and accessible to algebraic methods but potentially less realistic. However, both kinds of models for cryptographic protocols have been related. Also, symbolic models are very well suited to show that a protocol is broken , rather than secure, under

6975-574: The non-Greek deities had likely origins in more ancient European culture such as the ancient Germanic religion, while others may have been borrowed, for political reasons, from neighboring trade centers such as those in the Minoan or ancient Egyptian civilization.

7254-569: The principal group of gods, while the term ásynjur (singular ásynja ) refers specifically to the female Æsir . These terms, states John Lindow, may be ultimately rooted in the Indo-European root for "breath" (as in "life giving force"), and are cognate with Old English : os (a heathen god) and Gothic : anses . Another group of deities found in Norse mythology are termed as Vanir , and are associated with fertility. The Æsir and

The attacker may, however, re-use any messages that have been sent and therefore become known. The attacker can encrypt or decrypt these with any keys he knows, to forge subsequent messages. A protocol is modeled as a set of sequential runs, alternating between queries (sending a message over

7440-407: The same divine principle. Nontheistic religions deny any supreme eternal creator deity , but may accept a pantheon of deities which live, die and may be reborn like any other being. Although most monotheistic religions traditionally envision their god as omnipotent , omnipresent , omniscient , omnibenevolent , and eternal , none of these qualities are essential to the definition of

7533-538: The same idea. There are great deities found across the Pacific Ocean. Some deities are found widely, and there are many local deities whose worship is limited to one or a few islands or sometimes to isolated villages on the same island.

7719-476: The second half of the 20th century object relations theory , both in the States and among British Kleinians , set about "rethinking megalomania... intent on transforming an obstacle... into a complex organization that linked object relations and defence mechanisms " in such a way as to offer new "prospects for therapy". Edmund Bergler , one of his early followers, considered that "as Freud and Ferenczi have shown,

7812-634: The sphere of everyday life. Egyptian deities typically had an associated cult, role and mythologies.

These positions include, but are not limited to, the following: Thomas Aquinas acknowledged difficulty in comprehending the deity's power: "All confess that God is omnipotent; but it seems difficult to explain in what His omnipotence precisely consists: for there may be doubt as to the precise meaning of

8091-484: The two other words 'God can.'... It is no more possible for God than for the weakest of his creatures to carry out both of two mutually exclusive alternatives; not because his power meets an obstacle, but because nonsense remains nonsense even when we talk it about God. Sigmund Freud freely used the same term in a comparable way. Referring with respect to an adult neurotic to "the omnipotence which he ascribed to his thoughts and feelings", Freud reckoned that "this belief

8184-519: The union of the natures being such that they can neither be divided nor confused". Jesus Christ, according to the New Testament , is the self-disclosure of the one, true God, both in his teaching and in his person; Christ, in Christian faith, is considered the incarnation of God.

Ancient Roman scholars such as Varro and Cicero wrote treatises on the nature of gods of their times. Varro stated, in his Antiquitates Rerum Divinarum , that it

8556-450: The word 'all' when we say that God can do all things. If, however, we consider the matter aright, since power is said in reference to possible things, this phrase, 'God can do all things,' is rightly understood to mean that God can do all things that are possible; and for this reason He is said to be omnipotent." In Scholasticism , omnipotence is generally understood to be compatible with certain limitations or restrictions. A proposition that

8649-414: Was polytheistic, but had no centralized church, nor any sacred texts. The deities were largely associated with myths and they represented natural phenomena or aspects of human behavior.

Eos , the Greek goddess of
