Theodoret of Cyrus

Theodoret of Cyrrhus (c. 393–458) was a bishop, theologian, and church historian born and educated at Antioch who served as Bishop of Cyrrhus in Syria for roughly thirty-five years. A leading figure of the Antiochene theological school, he was drawn into the Christological controversies of the fifth century, opposing Cyril of Alexandria at the Council of Ephesus (431) and suffering exile after the Robber Council of Ephesus (449). He was fully vindicated at the Council of Chalcedon (451) and returned to his see, where he died around 458, leaving behind a vast corpus of biblical commentaries, polemical treatises, and the Ecclesiastical History.
