Not true. Sure there are differences and disagreements on territory where there is overlap - but the same was true for the Catholic Church, why else were there German, Irish, Italian parishes one block from each other?
Not true. Both Orthodoxy and Catholicism claim the right to be anywhere on earth, but not to have 10 bishops over the same territory, although this does happen to both for various reasons. The Greek Orthodox aren’t in Ukraine by the way, the Ukrainian Orthodox are - although divided into 3 groups.
These few Russian Orthodox are off the mark, just as some Latin Catholics keep trying to claim worldwide jurisdiction but keep limiting the Eastern Catholic Churches from doing the same.
Some do some don’t. This generalization absurd.
Good thing its not a serious concern to anyone.
Are you unaware of Avignon, the Frankish overtaking, the suppression of local Latin Rites - Sarum, Ambrosian, Gallican, Mozarabic, etc; and the suppression of Eastern Catholic Churches, which even extends to today in some areas - including the USA (see how married Eastern priests were treated by Latins)?
I think you have indirectly confirmed what I said. Orthodoxy is, indeed, territorial in its nature, and that’s a very important part of what it is to be Orthodox. It’s less so for those subject to the Patriarch of Constantinople, but very much so with Moscow. There are, indeed, territorial disputes between the two, and they’re not friendly disputes, either. In Ukraine there are Ukrainian Orthodox who recognize the Patriarch of Moscow as the head of their church, and there are Ukrainian Orthodox who recognize the Patriarch of Constantinople instead. The “Russian” patriarchate does not recognize the right of the “Greeks” to be in Ukraine at all.
I am aware that some claim indirect suppression of those Catholic rites like Gallican, Sarum, Ambrosian, but they all still exist, and nobody is suppressing them, tiny and very local though they are. They are differentiated from the regular Latin Rite (and not by a lot) only in liturgical practice, rather like the Anglican Use which the Vatican recently not only accepted but encouraged for former Anglican parishes.
The Latin Church does not exclude the Eastern Catholic Churches territorially from anywhere, and encourages them to continue. The Eastern Catholic churches have dioceses that overlap with Latin dioceses all over the United States, though they are smaller in population and larger in territorial extent. I am, for example, living within the Byzantine Catholic Eparchy (diocese) of Parma and simultaneously within the Latin diocese of Springfield/Cape Girardeau. My Archdiocese is St. Louis. The Eastern Churches can and do use the Latin basilica in St. Louis for liturgies. Not surprising that they would want to, since the basilica is Byzantine in design.
The Eparchy of Parma is multi state in extent. The diocese of Springfield/Cape Girardeau is about 1/4 of a state in extent. By way of further example, in order for an Eastern Catholic to become a parish member in a Latin parish, he has to have the consent of both the Eastern pastor and the Latin pastor. This is in order to encourage continued membership in the Eastern parish. The Eastern Catholic bishops have governance over their diocese in the same way the Latin bishops have governance over theirs. Eastern bishops are equal to Latin bishops in every way. There is no suppression of the Eastern Catholic Churches, though I think some believe that because long ago some secular rulers encouraged one over the other and today, in much of Europe and in the U.S. there is some shifting between the two on the part of parishioners. Generally speaking, there is no discouragement in one going from a Latin parish to an Eastern parish, but the Latin Church in no way encourages movement in the other direction. A person wouldn’t have to be on this forum very long to realize that continuing in an Eastern Catholic Church is encouraged by Latin Catholics, not discouraged.
The only real dispute among Catholic Churches of which I am aware is a particular Eastern Church that does not approve of its members marrying outside of its ethnic group. The Catholic Church does not accept that as a valid limitation and refuses to condemn such marriages.
There are Eastern Catholic cardinals, and Eastern bishops are eligible for election to the papacy, just as Latins are.
Some Ukrainian Orthodox are Greek in the sense that their ultimate patriarch is the Patriarch of Constantinople, not that of Moscow. All are, of course, divisions of Eastern Orthodoxy as opposed to Oriental Orthodoxy.
There were, at one time, nearly exclusively “Irish” or “German” or “Polish” parishes in the U.S. That was due to cultural and linguistic differences. Some were eventually merged when all could speak English. Not ten miles from where I sit there was what was once an “Irish” church and a “German” church. The Irish could almost all speak English when they got here. The Germans couldn’t. Both parishes are now for all nationalities. There is, however, in what was once the “Irish” church, a Hispanic Mass on Sunday for those Hispanics who can’t speak English. I do go to that Mass now and then, and am welcome to do so, though I’m not Hispanic. Some Hispanics go to the English Masses. There’s no real division.
