Theodore Abucara

Theodore Abū Qurrah (Greek: Θεόδωρος Ἀβουκάρας, Theodoros Aboukaras, Arabic: تواضروس أبو قرة‎‎, Tawaďros Abū-Qurrah; c. 750 – c. 823) was a 9th-century Orthodox Christian theologian who lived in the early Islamic period.

Theodore was born around 750 in the city of Edessa, in northern Mesopotamia, and was the Chalcedonian or Melkite bishop of the nearby city of Harran until some point during the archbishopric of Antioch, Theodoret (795–812). Later Michael the Syrian - who disapproved of Theodore - claimed that Theodoret had deposed him for heresy, although this is unlikely: Between 813 and 817 he debated with the Monophysites of Armenia at the court of Ashot Msakeri.

Around 814 Theodore visited Alexandria. On his way, he sojourned at Sinai where, for one Abū 'l-Tufayl, he wrote the Book of Master and Disciple (now ascribed to "Thaddeus of Edessa").

He died between 820 and 825.

Abū Qurrah was among the earliest Christian authors to use Arabic alongside Abu-Ra'itah of Tikrit, Ammar al-Basri and Abdulmasih al-Kindi. Some of his works were translated into Greek, and so circulated in Byzantium. He wrote thirty treatises in Syriac, but none of these have yet been identified. His writings provide an important witness to Christian thought in the early Islamic world. A number of them were edited with German translations by Georg Graf and have now been translated into English by John C. Lamoreaux.
