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][2] Theodoret plays a central role in the Life of the hermit Timothy of Kakhushta, who admonishes him for his luxurious living.
[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.
