The paper discusses the activity of the Armenian catholicos Yovhannēs Ōjnets̔i (717 – 728). It sets his polemical treatise against Paulicians, and its Christology, in the context of the council convened by the catholicos in Mantzikert with the participation of both Armenian and Syriac clerics. This council restored communion between two miaphysite Churches, Armenian and West-Syrian. Its significance also resides in the fact that it represented an initiative not of an overarching secular authority, but of separate ecclesiastical institutions. The circumstances conducive to the council’s convocation and its proceedings are analysed with reference to Armenian and Syriac historians of the eleventh to the thirteenth century.
