The term "Greek" does not refer to ethnic origin; the majority of these patriarchs were not ethnic Greeks. It refers to the fact that this church follows the Chalcedonian Orthodoxy associated with the (Greek-speaking) Byzantine Empire. Since 518, there have been two Orthodox patriarchs of Antioch: the Chalcedonian ones listed here, and the non-Chalcedonian Syriac Orthodox patriarchs of Antioch.
