[Petrosius]

I could be wrong, but I am quite sure the Catholic Church in Romania is part of the Church of Rome; so is the one in Bulgaria for that matter.

Bishop Alexandru Mesian belongs to the Romanian Greek-Catholic Church, a sui legis Byzantine rite church, i.e. a Catholic church united with Rome but not a part of the Church of Rome.

...Catholic church united with Rome but not a part of the Church of Rome.

To the Orthodox, that is a distinction without a difference (I hope you realize).
