Can you give some links or explain please.
Mar Bawai is under discipline, he has already been excommunicated from the Assyrian Church of the East. He does not represent that church in any capacity.
They have already been to court, and Mar Bawai lost his cathedral and all parish properties in his diocese. Mar Dinkha, the Patriarch, has already named a bishop as a replacement for Mar Bawai. From their point of view he should ask forgiveness and accept his discipline. Mar Bawai commands the loyalty of a portion of his former diocese, and probably sympathizers outside of it, but it represents a fragment of the Church of the East.
Accepting this man could actually be an expression of Uniatism, which has been condemned by the Balomond agreement as a means of attempting church unity. In other words, it is taking advantage of an internal dispute of another church to excise some people from it.
Try to imagine if a modern Roman Catholic bishop was excommunicated, and attempted to take his diocese out of the Roman Catholic church and into another. I am not arguing about whether it would be possible, I am asking you how it would feel…
If such a bishop receives “safe harbor” in some other church complete with his diocese, the original church is mightily offended. It can feel that it has been dialogged with in bad faith.
This happens to be why the TAC has not been welcomed with open arms (although in that case I think the Vatican is crazy for caring what the Anglican “non”-Communion thinks about such a move).
Apparently the Chaldean church has accepted this bishop, but I have to wonder if they had consulted with Rome first. Rome has not been quick to act upon such opportunities in the recent past.
