Patriarch Jeremias III of Constantinople illegally removed Patriarch Cyril VI from the See of Antioch even though Jeremias III had no jurisdiction over Antioch. Jeremias illegally appointed Sylvester of Antioch, a young Greek monk, to the patriarchal See of Antioch even though that See was legally held by Cyril VI. Jeremias illegally consecrated bishop Sylvester in Istanbul (why not in Antioch?) and placed him illegally into the territory of Antioch on October 8, 1724.Thank you for the information on St. Peter the Apostle Zekariya, though all the churches listed above are of apostolic origin, for the purpose of this thread and in relation to it, I believe the first bishop of the Melkite Greek Catholic Church would be Cyril VI Tanas.. I’m sorry I didn’t get to include Melkites in this thread, I couldn’t find any portrayals of Patriarch Cyril Tanas.
Ergo, the Melkites came into full communion with Rome, following the true Patriarch of Antioch. They were not a splinter group from Antioch; the Antiochian Orthodox are the splinter group (that is why we kept the historical name Melkite which the non-Chalcedonians gave us).
