My feeble two cents.....
This is utterly ridiculous. Look throughout history at how churches were planted in new lands, grew to great numbers through the grace of God, then were granted autocephaly, etc. History shows a complicated situation in some of these places where there were several ethnic Orthodox cultural groups in one area that ended up falling under one jurisdiction.
America needs an American Orthodox Church, not a hodge-podge salad bar of overlapping cultural churches. Orthodoxy gets a bad rap from many folks (Catholics love to play this card) for being "ethnic." And to some degree they deserve it. We need not only the perception of unity to potential converts, but the REALITY of unity for one another. We need a strong North American or just plain American patriarch and there are many wonderful men qualified for the task---Bishop Maxim of my Serb church is my first choice as draft pick!
We need to stop breaking our own canonical boundaries and rules overlapping for the sake of keeping cultural heritage alive.
The reasons I think this nonsense continues is pretty much two-fold. For one thing, the United States is a sinful, secular humanist, collapsing, vulture capitalist going socialist, confused, lost land of people. Perhaps the patriarchs in the old countries feel keeping the parishes and dioceses tied to the old country churches that still have a sense of morality will keep a better example and more hope? I don't know, but I don't think it matters much there. Secondly, good old fashioned human ethno-centrism. These Serbs, Russians, Bulgarians, Antiocheans, and such all want to keep a foothold and influence of their culture.
America has its own saints now that are titans!---St. Herman of Alaska, St. John of San Francisco, the new saint of my Serb jurisdiction---St. Sebastian of Jackson, etc.
We have our own heroes, we have awesome clergy here with huge potential to lead, and we have good parishioners ready to follow. We have amazing institutions like St. Vlad's Seminary and other amazing ones, and there is just too much potential to throw this away.
But where human beings are involved, ugh.....
Ok, end of my rant.
