It's not realistic to assume the remnant which stayed Catholic will ever want to be reunited with the Romanian Orthodox Church.
I was thinking about this comment this morning (yes, yes, I realize it was posted over a month ago).
One of the things that seems to me the most important of all is that the Orthodox must at some point be willing to (at the risk of sounding quaint or trite) let it go. I'm not, necessarily, saying that we are at that point already -- heck, for all I know I could live to see a wave of Romanian-Catholic-to-Orthodox conversions, though I'd be surprised. But I think that eventually
there must come a point when the Orthodox take-no-for-an-answer, so to speak.
Just my 1.5 cents.
