Abdissi (Abdisu, Abd-Jesu, Or Hebed-Gesu)
a monk of the Order of St. Pachomius, and afterwards patriarchi of Mosul, a city of Asiatic Turkey. He went to Rome between 1550 and 1555, and abjured Nestorianism; and after the death of Simon Suiacha he was made Latin patriarch of Mosul, which election was confirmed by Pius IV, who conferred on him the pallium, March 7, 1562. Thomassin relates that he was present at the Council of Trent. Sarpi, that he wrote an epistle to the synod, but was not present. Abdissi was perfect master of Chaldee, Arabic, and Syriac; he maintained that his ancestors had received their doctrine from Sts. Thomas and Thaddseus, and that their faith was in all respects conformable to that of the Roman Church. Before he abjured Nestorianism, Abdissi wrote various works in Syriac, in defence of his original faith, which are mentioned by Abraham Eccellensis, Catalogoue of Syiac Writers (Rome, 1653). — See Thomassin, pt. 1, bk. 1, c. 24 p. 9; Sarpi, Istoria del Concilio Tridentino.
