Theodoret was the Melkite (Greek) patriarch of Antioch in the late 8th century and possibly into the 9th, during the reign of the Abbasid caliph Harun al-Rashid. The exact dates of his patriarchate are the subject of disagreement.[1] Date ranges of c. 787–c. 799, 795–812 and c. 794–811 have been offered.[1][2]
Theodoret plays a central role in the Life of the hermit Timothy of Kakhushta, who admonishes him for his luxurious living.[3] The Life is the only source to record that he was arrested by Harun.[4] The saint's prayers reportedly saved him from execution and, when oil blessed by Timothy cured the caliph's son, the patriarch even received concessions for his flock.[2] The 12th-century Chronicle of Michael the Great reports that Theodoret deposed Theodore Abu Qurra as bishop of Harran, but doubt has been cast on the accuracy of this report.[5]
