Oriental Orthodox Churches

The Oriental Orthodox churches are an ancient communion that includes the Coptic Orthodox Church of Alexandria, the Ethiopian and Eritrean Orthodox Tewahedo Churches, the Syriac Orthodox Church of Antioch, the Armenian Apostolic Church, and the Malankara Orthodox Syrian Church of India. They accept the first three ecumenical councils but not the Council of Chalcedon (451). They confess the Trinity and that Christ is fully God and fully man.

How Theologica classifies this tradition

This church confesses the Trinity and the full deity of Christ in the creeds of the state church councils. But its teaching that grace comes through its sacraments, with tradition sharing Scripture's authority, departs from the Gospel itself on how a sinner is justified. We judge the teaching, not each member's heart.

Historical origins

Where It Came From

These churches trace their foundations to the apostolic age: by tradition, to Mark in Alexandria, Thomas in India, and Thaddeus and Bartholomew in Armenia. Like the Eastern Orthodox, they claim unbroken continuity with the apostles through their bishops. Theologica holds that the hierarchical churches of the East developed gradually, as in the West, and that Christ's churches of baptized believers remained distinct from them. Armenia became the first kingdom to adopt Christianity officially, early in the fourth century. These churches separated from the state church of Rome and Constantinople after the Council of Chalcedon (451), a council of state-church bishops called by the emperor Marcian, believing its language of two natures leaned toward the error of Nestorianism.
