Eastern Orthodox Churches

The Orthodox Church is a Christian body whose adherents are largely based in Russia, Greece, Eastern Europe and the Middle East, with a growing presence in the western world. Most Orthodox Christians accept the First seven Ecumenical Councils.

Orthodox Christianity identifies itself as the original Christian church founded by Christ and the Apostles, and traces its lineage back to the early church through the process of Apostolic Succession and unchanged theology and practice. Orthodox distinctives (shared with the Eastern Catholic Churches) include the Divine Liturgy, Mysteries or Sacraments, and an emphasis on the preservation of Tradition, which it holds to be Apostolic in nature.

* Autonomy not universally recognized

Some Orthodox do not acknowledge the following Church as autonomous & autocephalous:

Orthodox Church in America [Autocephaly granted in 1970 from its mother church, the Russian Orthodox Church. It is in full communion with all canonical Orthodox Churches and de facto, fully recognized by all. The Ecumenical Patriarchate accepts the OCA, but disputes the Russian Orthodox Church’s action]

Estonian Apostolic Orthodox Church [Autonomy recognized only by the Ecumenical Patriarchate]

Note, that the Russian Church recognized a different order of seniority, in which the Georgian church comes after the Church of Russia and the Albanian Church – after the Church of Greece.

The Church of Cyprus also has a different list featuring herself immediately after the ancient Patriarchates and before that of Moscow.

The jurisdiction of the Sinai peninsula could be Autocephalous but is disputed because it consists solely of a monastery and its metochia and its Archbishop is the Abbot who must be ordained by the Patriarch of Jerusalem


The following is list of some of the organizations that use the term “Orthodox” in their name but do not maintain communion with any of the 14 (15) autocephalous churches and thus are not typically considered part of the Orthodox Christian communion.

Oriental Orthodoxy refers to the churches of Eastern Christian tradition that keep the faith of the first three Ecumenical Councils of the undivided Church: the First Council of Nicaea (AD 325), the First Council of Constantinople (381) and the Council of Ephesus (431), and rejected the dogmatic definitions of the Council of Chalcedon (451). Hence, these churches are also called Old Oriental Churches.
