Well, yes, because they are more disunited than the Orthodox are with the Catholics these days! There are three men calling themselves the Patriarch of Kiev or some such right now.
And, of course, the Russian backed Church loves to portray itself as a victim in all of this: http://02varvara.wordpress.com/2009/11/30/the-schism-in-orthodoxy-in-the-ukraine-distresses-the-entire-orthodox-church-an-official-appeal-of-the-holy-synod-of-the-uocmp/
So many Orthodox churches in Ukraine - they will never unite let alone resolve with Moscow.
And this would be contrary to Traditional Catholic teaching....once again.
I am still amazed that it's even up for discussion.
Europe is still very tribal. Ethnic identity seems to trump all else. The history of Orthodoxy in the US is atypical. However, as the US ethnic enclaves dissipate, at least Orthodox unity is more likely here. More and more parishes are becoming pan-orthodox.
If it were up to Francis all protestants would be going up for Communion in any Catholic Church. My prediction is this will his major issue after he allows divorced to receive communion.He passed out communion to shacked up couples all over Argentina. Doctrine means nothing to him.
