I was talking to a Melkite priest today and I was told that, even though the Melkites have cut mutual sacramental ties with the Antiochian Orthodox, on the other hand Constantinople feels "compelled" towards the Melkites due to the historical events that lead to their schism, deeming the Melkite church as a sister church to the Greek Orthodox church, rather than a "traitor" church like with the UGCC, with whom they kept no ties, hence that it's pretty much up to the priest whether to allow it or not, but that technically the Melkites are still in communion with the Greek Orthodox and can receive Holy Communion at a Greek Orthodox parish. Is this true?
