Through Jesus and Roman Empire

The Great Church, also called the catholic (i.e., universal) Church, has been defined also as meaning "the Church as defended by such as Ignatius of Antioch, Irenaeus of Lyons, Cyprian of Carthage, and Origen of Alexandria and characterized as possessing a single teaching and communion over and against the division of the sects, e.g., gnosticism, and the heresies".

By the beginning of the fourth century, the Great Church already formed about 15% of the population of the Roman Empire and was ready, both numerically and structurally, for its role as the church of the empire, becoming the state religion of the Roman Empire in 380.

Roger F. Olson says: "According to the Roman Catholic account of the history of Christian theology, the Great Church catholic and orthodox lived on from the apostles to today in the West and all bishops that remained in fellowship with the bishop of Rome have constituted its hierarchy"; or, as the Catholic Church itself has expressed it, "This Church constituted and organized in the world as a society, subsists in the Catholic Church, which is governed by the successor of Peter and by the Bishops in communion with him, although many elements of sanctification and of truth are found outside of its visible structure." Thus, the Roman Catholic Church identifies itself as the continuation of the Great Church, which in turn was the same as the early Church founded by Jesus Christ. Because of this, it identifies itself as the "one true church".

The unbroken continuity of the Great Church is affirmed also by the Eastern Orthodox Church: "Orthodoxy regards the Great Church in antiquity (for most of the first millennium) as comprising, on one side, the Eastern Orthodox world (the Byzantine patriarchates presided over by the hierarch of the Church of Constantinople together with the Slavic Orthodox churches); and, on the other side, the Western Catholic Church, presided over by the hierarch of the Church of Rome."

Emergence

Lawrence S. Cunningham, and separately, Kugel and Greer state that Irenaeus's statement in Against Heresies Chapter X 1–2 (written c. 180 AD) is the first recorded reference to the existence of a "Church" with a core set of shared beliefs as opposed to the ideas of dissident groups. Irenaeus states:

The Church, though dispersed through the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith: ... As I have already observed, the Church, having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it. ... For the churches which have been planted in Germany do not believe or hand down anything different, nor do those in Spain, nor those in Gaul, nor those in the East, nor those in Egypt, nor those in Libya, nor those which have been established in the central regions of the world. But as the sun, that creature of God, is one and the same throughout the whole world, so also the preaching of the truth shineth everywhere, and enlightens all men that are willing to come to a knowledge of the truth.

Cunningham states that two points in Irenaeus' writing deserve attention. First, that Irenaeus distinguished the Church singular from "the churches" plural, and more importantly, Irenaeus holds that only in the larger singular Church does one find the truth handed down by the apostles of Christ.

At the beginning of the 3rd century the Great Church that Irenaeus and Celsus had referred to had spread across a significant portion of the world, with most of its members living in cities (see early centers of Christianity). The growth was less than uniform across the world. The Chronicle of Arbela stated that in 225 AD, there were 20 bishops in all of Persia, while at approximately the same time, surrounding areas of Rome had over 60 bishops. But the Great Church of the 3rd century was not monolithic, consisting of a network of churches connected across cultural zones by lines of communication which at times included personal relationships.

The Great Church grew in the 2nd century and entered the 3rd century mainly in two empires: the Roman and the Persian, with the network of bishops usually acting as the cohesive element across cultural zones. In 313, the Edict of Milan ended the persecution of Christians, and by 380 the Great Church had gathered enough followers to become the State church of the Roman Empire by virtue of the Edict of Thessalonica.
