The Patriarch of Antioch Schism.
PATRIARCH OF ANTIOCH SCHISM.
The Syriac Non-Chalcedonians recognized Severus as the legitimate Patriarch until his death in 538. In 544, Non-Chalcedonian leader Jacob Baradaeus consecrated Sergius of Tella as bishop of Antioch, opening the lasting schism between the Greek Orthodox Church of Antioch, part of the Eastern Orthodox Church, and the Syriac Orthodox Church, part of Oriental Orthodoxy. .
