Hesychios: There may be some truth to your comment; that being said, the reality is that the diminished authority of the local metropolitan has the result of only INCREASING the autonomy of the local bishop. There are approximately 2000 local Ordinaries in the Latin Church…and in practice they more or less are accountable only to the Pope, who hardly intervenes in the day-to-day affairs of obscure Latin dioceses in the far corners of the world. Meanwhile, Eastern metropolitans are exercising real and substantial jurisdiction over their bishops…
I think that this is because the central authority model does not work very well.
The Vatican (read: Pope) has full responsibility for the selection of bishops in the western church, although in fact any one person would be hard pressed to know so many people very well. So the selection process has become institutionalized.
A priest candidate gets good grades in college, and goes to Rome for further studies. These people become familiar with members of the Curia there and vice versa. Later, back home they have something of an edge for having studied in Rome, and when they are named as candidates “so-and-so already knows that lad, he’s a good fellow. really bright”, and the system can be ‘worked’ in this way. Get good grades in a good school, go to Rome and get noticed. Make dad proud.
As for the reason, it has to be more complicated than we can discuss here in an equitable manner. However I will say that, historically, the local churches became dominated by the local nobility and royalty subsequent to Europe being converted. This was an abusive in the east-west-north-south, basically all over.
In the west one can see the investiture controversy as symptom of that. The power of the Papacy was promoted and enhanced as an antidote to many of these problems as a reform.
The real substantial changes came, I think, when the Papacy began concluding concordats with governments in Europe. I don’t know when this began, but probably the most significant one was with Napoleon. Usually this resulted in the Pope being given the right to name bishops in a country as one of the terms.
I am working from memory, so I can’t make any references right now, but one can read about these things in any library.
The concordat with France was significant because the hierarchy of the church in France was closely associated with the old regime and the rich aristocracy, and during the French Revolution the church was swept away along with the Monarchy in a very bloody episode. Napoleon came to power after the French revolution had just about run it’s course. I recall reading that the government reduced the number of dioceses in France from 150 (or something like that) to fifty, consolidating them into compact and geographically sensible operations. The government also assumed ownership of church property, and the famous cathedrals became national treasures.
Napoleon wanted to curry favor with the rural Catholics and win their support and allegiance. The locals did not love or trust the old bishops and probably didn’t care to see them come back, but they trusted the Pope, who was far away and had a certain mystique. Napoleon granted the Pope the right to name the bishops of France in return for agreeing to the other changes the French government had made to the church organization.
Different processes were at work in different countries, but the result was the Vatican eventually got the right to name bishops in most place across Europe, and remolded the church.
Another example would be in Britain, which lost it’s church altogether under Elizabeth. When Catholicism was finally allowed to function legally once again, the Pope gave them bishops and laid out the diocesan boundaries. I don’t think there was a concordat involved.
When Holland finally allowed Catholicism to be legally followed, the Pope named new bishops for the country, bypassing the local recusant church entirely. The church had survived underground during the Protestant suppression with it’s own Metropolitan line intact, but the Pope did not recognize them.
By the time Pius IX was Pope, most bishops in Europe owed their appointments to the Vatican.
