(Gregory of Antioch), a Greek theologian of the 6th century. First a monk at Constantinople, he became afterwards abbot of a monastery on Mt. Sinai. The Arabs besieged the convent, but he succeeded in making peace with them and in keeping it. He was appointed patriarch of Antioch on the deposition of Anstasinius A.D. 570 or 571 (Baroniuss makes it A.D. 573).
One of his friends, Astohlius, was put to death with severe tortures on a charge of magic, and the people of Antioch 'accused Gregory of complicity' with him, but he was acquitted. His enemies then charged him with incest with his own sister of this, too, he was acquitted. Weary of con tention, Gregory gaves up his see to Anastasius, and soon after died (about A.D. 594). He distinguished himself by his hostility to the Acephali (q.v.). When the imperial troops rebelled in Persia, Gregory brought them back by an oration, which is preserved by Evagrius, under the title Δηυογορία πρὸς τὸν στρατόν: he wrote salso λόγος εἰς τὰς μυροφόρους (oratio in mulieres unguentiferas), and both are given in Gallandii Bibl Paltrum, t. 12; See Evagrius, Hist. Eccl. 5:6, 18; 6:4, 11, 18, 24; Smith, Dict, of Gr. and Rom. Biog. and Myth. 2:308; Hoefer, Nouv. Biog. Generale, 21:875.
