Syriac Orthodox Church
In the fifth century, many in the church in Syria rejected the pronouncements of the fourth Ecumenical Council (Chalcedon, 451) and the patriarchate split into two factions each claiming the heritage of Antioch. The Syrian Orthodox Church continues the beliefs and practice of those who rejected the council's statements. It uses Aramaic (the language spoken by Jesus and the Apostles) as its liturgical language. The ancient St. Thomas Church based in Malankara, India, is an integral part of the Syriac Orthodox Church.
