Christology in the context of "Pre-existence of Christ"

Christianity is an Abrahamic monotheistic religion, which states that Jesus is the Son of God and rose from the dead after his crucifixion, whose coming as the messiah (Christ) was prophesied in the Old Testament and chronicled in the New Testament. It is the world's largest and most widespread religion with over 2.3 billion followers, comprising around 28.8% of the world population. Its adherents, known as Christians, are estimated to make up a majority of the population in 120 countries and territories.

Christianity remains culturally diverse in its Western and Eastern branches, and doctrinally diverse concerning justification and the nature of salvation, ecclesiology, ordination, and Christology. Most Christian denominations, however, generally hold in common the belief that Jesus is God the Son—the Logos incarnated—who ministered, suffered, and died on a cross, but rose from the dead for the salvation of humankind; this message is called the gospel, meaning the "good news". The four canonical gospels of Matthew, Mark, Luke and John describe Jesus' life and teachings as preserved in the early Christian tradition, with the Old Testament as the gospels' respected background.

A Christian denomination is a distinct religious body within Christianity that comprises all church congregations of the same kind, identifiable by traits such as a name, particular history, organization, leadership, theological doctrine, worship style and, sometimes, a founder. It is a secular and neutral term, generally used to denote any established Christian church. Unlike a cult or sect, a denomination is usually seen as part of the Christian religious mainstream. Most Christian denominations refer to themselves as churches, whereas some newer ones tend to interchangeably use the terms churches, assemblies, fellowships, etc. Divisions between one group and another are defined by authority and doctrine; issues such as the nature of Jesus, the authority of apostolic succession, biblical hermeneutics, theology, ecclesiology, eschatology, and papal primacy may separate one denomination from another. Groups of denominations—often sharing broadly similar beliefs, practices, and historical ties—are sometimes known as "branches of Christianity". These branches differ in many ways, especially through differences in practices and belief.

Individual denominations vary widely in the degree to which they recognize one another. Several groups say they are the direct and sole authentic successor of the church founded by Jesus Christ in the 1st century AD. Others, however, believe in denominationalism, where some or all Christian groups are legitimate churches of the same religion regardless of their distinguishing labels, beliefs, and practices. Because of this concept, some Christian bodies reject the term "denomination" to describe themselves, to avoid implying equivalence with other churches or denominations.

A Christian denomination is a distinct religious body within Christianity, identified by traits such as a name, organization and doctrine. Individual bodies, however, may use alternative terms to describe themselves, such as church, convention, communion, assembly, house, union, network, or sometimes fellowship. Divisions between one denomination and another are primarily defined by authority and doctrine. Issues regarding the nature of Jesus, Trinitarianism, salvation, the authority of apostolic succession, eschatology, conciliarity, papal supremacy and papal primacy among others may separate one denomination from another. Groups of denominations, often sharing broadly similar beliefs, practices, and historical ties—can be known as "branches of Christianity" or "denominational families" (e.g. Eastern or Western Christianity and their sub-branches). These "denominational families" are often imprecisely also called denominations.

Christian denominations since the 20th century have often involved themselves in ecumenism. Ecumenism refers to efforts among Christian bodies to develop better understandings and closer relationships. It also refers to efforts toward visible unity in the Christian Church, though the terms of visible unity vary for each denomination of Christianity, as certain groups teach they are the one true church, or that they were divinely instituted for the propagation of a certain doctrine. The largest ecumenical organization in Christianity is the World Council of Churches.

The Christianization of Iberia (Georgian: ქართლის გაქრისტიანება, romanized: kartlis gakrist'ianeba) refers to the spread of Christianity in the early 4th century as a result of the preaching of Saint Nino in the ancient Georgian kingdom of Kartli, known as Iberia in classical antiquity. The then-pagan king of Iberia Mirian III declared Christianity to be the kingdom's state religion. According to Roman historian Sozomen, this led the king's "large and warlike barbarian nation to confess Christ and renounce the religion of their fathers", as the polytheistic Georgians had long-established anthropomorphic idols, known as the "Gods of Kartli". The king would become the main sponsor, architect, initiator and an organizing power of all building processes.

Per Socrates of Constantinople, the "Iberians first embraced the Christian faith" alongside the Abyssinians, present day Ethiopians but the exact date of the event is still debated. The kings of Georgia and Armenia were among the first monarchs anywhere in the world to convert to the Christian faith. Prior to the escalation of the Armeno-Georgian ecclesiastical rivalry and the Christological controversies, their Caucasian Christianity was extraordinarily inclusive, pluralistic and flexible that only saw the rigid ecclesiological hierarchies established much later, particularly as "national" churches crystallised from the 6th century. Despite the tremendous diversity of the region, the Christianization process was a pan-regional and a cross-cultural phenomenon in the Caucasus, Eurasia's most energetic and cosmopolitan zones throughout the late antiquity, hard enough to place Georgians and Armenians unequivocally within any one major civilization.

Holy Wisdom (Ancient Greek: Ἁγία Σοφία, romanized: Hagia Sophia, Latin: Sancta Sapientia) is a concept in Christian theology.

Christian theology received the Old Testament personification of Wisdom (Hebrew Chokmah) as well as the concept of Wisdom (Sophia) from Greek philosophy, especially Platonism. In Christology, Christ the Logos as God the Son was identified with Divine Wisdom from earliest times.

John Philoponus (Greek: /fɪˈlɒpənəs/; Ἰωάννης ὁ Φιλόπονος, Ioánnis o Philóponos; c. 490 – c. 570), also known as John the Grammarian or John of Alexandria, was a Coptic Miaphysite philologist, Aristotelian commentator and Christian theologian from Alexandria, Byzantine Egypt, who authored a number of philosophical treatises and theological works. John Philoponus broke from the Aristotelian–Neoplatonic tradition, questioning methodology and eventually leading to empiricism in the natural sciences. He was one of the first to propose a "theory of impetus" similar to the modern concept of inertia over Aristotelian dynamics. He is also the historical founder of what is now called the Kalam cosmological argument.

Later in life Philoponus turned to Christian apologetics, arguing against the eternity of the world in his De opificio mundi, a theory which formed the basis of pagan attacks on the Christian doctrine of Creation. He also wrote on Christology, espousing a Miaphysite view. His by-name ὁ Φιλόπονος translates as "lover of toil", i.e. "diligent," referring to a miaphysite confraternity in Alexandria, the philoponoi, who were active in debating pagan (i.e. Neoplatonic) philosophers.

The Syriac Orthodox Church (Classical Syriac: ܥܺܕܬܳܐ ܣܽܘܪܝܳܝܬܳܐ ܬܪܺܝܨܰܬ݂ ܫܽܘܒܚܳܐ, romanized: ʿIdto Sūryoyto Trīṣāth Šubḥō), also informally known as the Jacobite Church, is an Oriental Orthodox denomination that originated from the Church of Antioch. The Church currently has around 1.5 million followers worldwide. The Church upholds the Miaphysite doctrine in Christology and employs the Liturgy of Saint James, associated with James the Just. Classical Syriac is the official and liturgical language of the Church.

The supreme head of the Syriac Orthodox Church is the patriarch of Antioch, a bishop who, according to sacred tradition, continues the leadership passed down from Saint Peter. Since 2014, Ignatius Aphrem II has served as the Syriac Orthodox Antiochian patriarch. The Great Church of Antioch was the patriarchal seat and the headquarters of the Church until c. 518, after which Severus of Antioch had to flee to Alexandria, Egypt. After the death of Severus, the patriarchal seat moved from Egypt to different monasteries like the Mor Bar Sauma Monastery; some patriarchs also set up headquarters in Antioch temporarily. Later, Mor Hananyo Monastery was declared as the patriarchal seat and the headquarters of the Church from c. 1160 until 1932. In 1959, the patriarchal seat and headquarters were relocated to the Cathedral of Saint George in Bab Tuma, Damascus, Syria, due to conflicts in the region.

In the year before the First Council of Constantinople in 381, Nicene Christianity became the official religion of the Roman Empire when Theodosius I, emperor of the East, Gratian, emperor of the West, and Gratian's junior co-ruler Valentinian II issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy, as defined by the Council of Nicea, as the Roman Empire's state religion. Historians refer to this state-sponsored church using a variety of terms: the catholic church, the orthodox church, the imperial church, the Roman church, or the Byzantine church, with some also used for wider communions extending beyond the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church all claim to stand in continuity from the Nicene Christian church to which Theodosius granted recognition. Political differences between the Eastern Roman Empire and the Persian Sassanid Empire led to the separation of the Church of the East in 424. A doctrinal split within the imperial church led to the independence of early Oriental Orthodoxy, while the fall of the Western Roman Empire initiated the gradual separation between Eastern and Western Christianity, culminating in the East-West schism of 1054. The Western Church evolved into the Latin Catholic Church while the Eastern Church that remained under the patronage of the Eastern empire and evolved into the Greek Orthodox Church.

Earlier in the 4th century, following the Diocletianic Persecution of 303–313 and the Donatist controversy that arose in consequence, Constantine the Great had convened councils of bishops to define the orthodoxy of the Christian faith and to expand on earlier Christian councils. A series of ecumenical councils convened by successive Roman emperors met during the 4th and the 5th centuries, but Christianity continued to suffer rifts and schisms surrounding the theological and christological doctrines of Arianism, Nestorianism, Miaphysitism, and Dyophysitism. In the 5th century, the Western Roman Empire decayed as a polity; invaders sacked Rome in 410 and in 455, and Odoacer, an Arian barbarian warlord, forced Romulus Augustus, the last nominal Western Emperor, to abdicate in 476. However, apart from the aforementioned schisms, the church as an institution persisted in communion, if not without tension, between the East and West. In the 6th century, the Byzantine armies of the Byzantine Emperor Justinian I recovered Italy and other regions of the Western Mediterranean shore. The Byzantine Empire soon lost most of these gains, but it held Rome, as part of the Exarchate of Ravenna, until 751, a period known in church history as the Byzantine Papacy. The early Muslim conquests of the 7th–9th centuries would begin a process of converting most of the then-Christian world in the Levant, Middle East, North Africa, regions of Southern Italy and the Iberian Peninsula to Islam, severely restricting the reach both of the Byzantine Empire and of its church. Christian missionary activity directed from the capital of Constantinople did not lead to a lasting expansion of the formal link between the church and the Byzantine emperor, since areas outside the Byzantine Empire's political and military control set up their own distinct churches, as in the case of Bulgaria in 919.
