Get off it. The Orthodox accept all 7 ecumenical councils (which state that the Bishop of Rome is the first in precedence and that there is One, Holy, Catholic, and Apostolic Church).
No, I won’t “get off it”.
They do not accept that the Catholic Church is the one true church or they wouldn’t be separated from it. Agreeing that the “Bishop of Rome” is first is not the same as agreeing that it he is supreme.
I’m so tired of the false ecumenism. When we have opportunities to be ecumenical, it should include clear language about the necessity of being Catholic. We never see that though.
