I am talking with some Orthodox Christians about unification and one of the things they brought up for the excessive control of Rome over the Eastern Particular churches as a reason for maintaining separation. Here is my question. How much influence does Rome have over your Church? Does Rome get involved in raising and deposing Bishops, canon law, liturgy, etc. and if so how much?
According to canon law, the Pope has jurisdiction over all churches, how this jurisdiction is carried out is different for each Eastern Church. The Pope is the visible head while Christ is the real Head of the Church. The Pope works though the curia, in this case it would be the Congregation for Oriental Churches.
The Eastern Catholic Churches are in communion with the Pope, that means that the Pope recognizes the sacraments of the Eastern Rites, and that we share the same faith. However, according to Church theology, each bishop is a successor to the Apostles, and the head of their own diocese, or “eparchies” in the east. Therefore the Pope, being first and foremost the Bishop of Rome is not the formal head of various Eastern Rite Churches, for example, Patriarch Gregory III is the head of the Melkite Greek Catholic Church, and Stephanos II is the head of the Coptic Catholic Church.
On top of that, there are different Church hierarchies for each Eastern Rite Church. There are 4 hierarchies, patriarchal, major archepiscopal, metropolitan, and “other”. A Patriarchal Church is one headed by a patriarch. For example the Chaldean, Armenian, Coptic, Syriac, Maronite, and Melkite Catholic Churches. A Patriarch is elected by a synod of his own churches bishops without approval from the Pope, but the Pope is informed of the decision. Major Archepiscopal are churches headed by an Archbishop, for example, the Romanian, Ukrainian, Syro-Malabar, and Syro-Malankara Catholic Churches. The Archbishop is elected by his own bishops but the decision must be confirmed by the Pope.
The Metropolitan Churches are headed by a Metropolitan Bishop who is appointed by Rome. These churches have their territorial boundaries defined by the Pope through the Congregation for Oriental Churches. These Churches include the Ruthenian and Ethiopian Catholic Churches. Lastly, there are churches with none of their own hierarchy, these include the Greek, Bulgarian, Hungarian, Slovak, Belarusian, Albanian, Georgian, and Russian Catholic Churches. Since they have no hierarchy of their own, they are oversaw by the local Latin Rite Bishop.
So, in the Eastern Catholic circle, there are various views of the Pope as he relates to our own hierarchy. And the Pope takes various roles, ranging from very active, to virtually non existent roles in governing the Eastern Catholic Churches.
