Eastern Orthodoxy traces its roots to the time of the Gospels.
Chalcedonian Schism
In the 5th century, primarily due to differing viewpoints of the dogmatic definitions from the Council of Chalcedon in 451, the Oriental Orthodox broke away from the Eastern Orthodox faith. The Oriental Orthodox Faiths are the following:
Armenian Apostolic Orthodox Church
Indian (Malankara Orthodox Syrian Church)
Armenian Catholicosate of the Great House of Cilicia
Orthodox Tewahedo, which consists of the Ethiopian Orthodox Church as well as the Eritrean Orthodox Church, both in the African continent.
