Eastern Orthodox Church

The Eastern Orthodox Church, officially the Orthodox Catholic Church, also referred to as the Orthodox Church, Eastern Orthodoxy, and Orthodoxy, is the second largest Christian Church in the world, with an estimated 225–300 million adherents.

The Eastern Orthodox Church is one of the oldest religious institutions in the world, teaching that it is the One, Holy, Catholic and Apostolic Church established by Jesus Christ in his Great Commission to the apostles, and practicing what it understands to be the original faith passed down from the Apostles.

United in communion with the Latin Church before the East–West Schism in 1054, and with the Oriental churches for the first quarter of its history, Eastern Orthodoxy spread throughout the Roman and later Byzantine Empires and beyond, playing a prominent role in European, Near Eastern, Slavic, and some African cultures. Its most prominent episcopal see is Constantinople.

Eastern Orthodoxy has no Papacy or similar authority, but instead teaches that all bishops are equal by virtue of their ordination, and each autocephalous church is typically governed by a Holy Synod. This is one of the main reasons for the division between the Roman Catholic Church and the Eastern Orthodox Church. The commonly-used but unofficial designation "Eastern" derives from the geographical location of the main centers of Orthodoxy in relation to the "Western" churches (now known as the Roman Catholic Church), and from Constantinople being the capital of the Eastern Roman Empire.

Greek Orthodox Church

The name Greek Orthodox Church (Greek: Ἑλληνορθόδοξη Ἑκκλησία, Ellinorthódoxi Ekklisía, IPA: [elinorˈθoðoksi ekliˈsia]) is a term referring to the body of several Churches within the larger communion of Eastern Orthodox Christianity, whose liturgy is or was traditionally conducted in Koine Greek, the original language of the New Testament, and whose history, traditions, and theology are rooted in the early Church Fathers and the culture of the Byzantine Empire. Greek Orthodox Christianity has also traditionally placed heavy emphasis and awarded high prestige to traditions of Christian monasticism and asceticism, with origins in Early Christianity in the Near East and in Byzantine Anatolia. Today, the most important centres of Christian Orthodox monasticism are Saint Catherine's Monastery in the Sinai Peninsula (Egypt) and Mount Athos in Greek Macedonia (Northern Greece).

Overview

The Greek Orthodox churches are descended from churches which the Apostles founded in the Balkans and the Middle East during the first century A.D., and they maintain many traditions practiced in the ancient Church. Orthodox Churches, unlike the Catholic Church, have no Bishopric head, such as a Pope, and hold the belief that Christ is the head of the Church. However, they are each governed by a committee of Bishops, called the Holy Synod, with one central Bishop holding the honorary title of "first among equals."

The Russian Orthodox Church (ROC; Russian: Ру́сская правосла́вная це́рковь, tr. Rússkaya Pravoslávnaya Tsérkov), alternatively legally known as the Moscow Patriarchate (Russian: Моско́вский Патриарха́т, tr. Moskóvskiy Patriarkhát), is one of the autocephalous Eastern Orthodox churches, in full communion with other Eastern Orthodox patriarchates. The Primate of the ROC is the Patriarch of Moscow and all Rus'. The ROC, as well as the primate thereof, officially ranks fifth in the Orthodox order of precedence, immediately below the four ancient Patriarchates of the Greek Orthodox Church, those of Constantinople, Alexandria, Antioch, and Jerusalem. The official Christianization of Kievan Rus' widely seen as the birth of the ROC is believed to have occurred in 988 through the baptism of the Kievan prince Vladimir and his people by the clergy of the Ecumenical Patriarchate whose constituent part the ROC remained for the next six centuries, while the Kievan see remained in the jurisdiction of the Ecumenical Patriarchate until 1686.
