The Patriarch of Antioch also bears the title, Antioch and all the East. That would include the Arabian Peninsula and Qatar.Samn! said:In terms of "long-term pastoral care", the last time before very recently that there were Orthodox churches in the Persian Gulf region, which was before the Mongols, they were under the Orthodox Catholicos of Baghdad, who was under the Patriarch of Antioch. Jerusalem has pretty much no history of activity outside modern Palestine and Jordan prior to this Qatari adventure. Part of the controversy here is that Jerusalem's "Archbishop of Qatar" claims Kuwait, where there is an Antiochian parish and where the Antiochian metropolitan of Baghdad often resides.
"Arabia" in the Patriarch of Jerusalem's title refers to the Roman Province of Arabia, just like "the East" in Antioch's title refers to the Province of Oriens.
Here, for example, though, is an account of the extent of the Patriarchate of Antioch by the 18th century historian Mikhail Breik: http://araborthodoxy.blogspot.fr/2009/06/patriarchate-of-antioch-according-to.html
