The History of the Church is a vital part of the Orthodox Christian faith. Orthodox Christians are defined significantly by their continuity with all those who have gone before, those who first received and preached the truth of Jesus Christ to the world, those who helped to formulate the expression and worship of our faith, and those who continue to move forward in the unchanging yet ever-dynamic Holy Tradition of the Orthodox Church.

The first thousand years of her history the Church was essentially one. Five historic Patriarchal centers--Jerusalem; Antioch, Rome, Alexandria, and Constantinople-- formed a cohesive whole and were in full communion with each other. There were occasional heretical or schismatic groups going their own way, to be sure; but the Church was unified until the 11th century. Then, in events culminating in A.D.1054, the Roman Patriarch pulled away from the other four, pursuing his long-developing claim of universal headship of the Church.

Today, nearly a thousand years later, the other four Patriarchates remain intact, in full communion, maintaining that Orthodox apostolic faith of the inspired New Testament record. The Orthodox Church and her history is described herein, from Pentecost to the present day.

Scholars estimate there are over 2,600 groups today who lay claim to being the Church, or at least the direct descendants of the Church described in the New Testament. Most all of the 2,600 groups come from the Roman Patriarchal side of the timeline showing the church roots.

All historians agree today that the schism which eventually became a permanent form of separation between Eastern and Western Christians did not occur suddenly. It was the result of a progressive "estrangement". Whatever the issues and whoever was at fault, it is clear that, underneath the debate on a concrete theological or disciplinary problem, there was a developing difference on the repective authority of the "apostolic see" of Rome on the one side, and on the other, the idea of a conciliar consensus prevailing in the East.

: Some of these dates are necessarily a bit vague, as records for some periods are particularly difficult to piece together accurately. The division of Church History into separate eras as we do here will always be to some extent arbitrary, though we have tried to group periods according to major watershed events. This timeline is necessarily biased toward the history of the Orthodox Church, though a number of non-Orthodox events are mentioned for their importance in history related to Orthodoxy.

History of Orthodox Christianity - A 3-part series by GOTelecom - QuickTime format

Part 1: Beginnings - Journey begins with the founding of the Church, the spread of Christianity to "nations" by the Apostles, the Gospel and the institution of Sacraments

Part 2: Byzantium - After the stabilization of the Church, the journey continues through the period of the Nicene Creed, Patristic Scriptures, Divine Liturgy and Icons. During this same period, however, the official division of East and West is witnessed and concludes with a gradual rift in matters of faith, dogma, church customs, politics and culture

Part 3: A Hidden Treasure - The Church becomes the only institution perceived by Greeks as the preserver of their national identity during 400 years of Turkish rule. By the end of the 19th century, a worldwide Orthodox community is born and the Church expands its influence to major social and philanthropic concerns.
