Eastern Orthodox Church

The Eastern Orthodox Church, also known as the Orthodox Church, is the second-largest Christian church, with approximately 220 million baptized members. It operates as a communion of autocephalous churches, each governed by its bishops in local synods. The church has no central doctrinal or governmental authority analogous to the Pope of the Roman Catholic Church, but the Ecumenical Patriarch of Constantinople is recognized by all as primus inter pares (first among equals) of the bishops.

The history of the Eastern Orthodox Church is traced back to Jesus Christ and the Apostles, through the Byzantine Empire. The church considers itself to be the continuation of the original Christian community established by Jesus and his apostles. The Great Schism of 1054 divided the Christian church into the Western (Roman Catholic) and Eastern (Orthodox) branches.
