Theodoret

Theodoret of Cyrus or Cyrrhus (Greek: Θεοδώρητος Κύρρου; c. AD 393 – c. 458/466) was an influential theologian of the School of Antioch, biblical commentator, and Christian bishop of Cyrrhus (423–457). He played a pivotal role in several 5th-century Byzantine Church controversies that led to various ecumenical acts and schisms. He wrote against Cyril of Alexandria's 12 Anathemas which were sent to Nestorius and did not personally condemn Nestorius until the Council of Chalcedon. His writings against Cyril were included in the Three Chapters Controversy and were condemned at the Second Council of Constantinople. Some Chalcedonian and East Syriac Christians regard him as blessed.
