That's incorrect, actually. The Coptic Church and the Assyrian Church are not Eastern Orthodox Christians and are not in communion with us.
...and the Orthodox, by their structure or lack thereof, are notoriously nationalistic and always clothe their natinonalism in religion.
Oh, I see. You're just an Orthodox-hating bigot vomiting forth lies.
And Orthodox churches hate the West, for cultural reasons.
And your lies server your master well.
