To put it in the proper perspectiuve: the Russian Church represents about 80% of the world Orthodox; the Serbs about 3%. That between 6/7 and 7/8 of all Orthodox put together.
The more the merrier-—although judging by the wording in Catholic article - the Roman Bishopric is not too happy. How brotherly.
