The claimed autocephally of the OCA.
http://www.orthodoxwiki.org/ROCOR_and_OCA
To this day, only the Churches of Russia, Bulgaria, Poland, Georgia, and the Czech Lands and Slovakia recognize the autocephaly of the OCA.

Considering the crisis the East Europe churches experienced in 1917 I'd say it's their call on the autocephally OCA.
The only ones with a legitimate qualm is ROCOR which itself is returning to communion with the MP, and them only because of the properties lost when the OCA was granted autocephally.
The rest are mostly playing a game of holier than thou.
All I can say to that is shame, shame, shame to all. Whether it be Serbs who, coming from communist backwoods have no clue about Orthodoxy or manners for that matter, whether it be power-grabbing games that go on between the "big" and the "petit" (Hermann the Cherusker's favorite expression -- but apparently quite true!) Patriarchiates, whether it be "independent" minded OCA and its pretend "authocephaly" supported by the "coalition of the willing" (where have I heard that before), made up of such "giants" known to toe the line as the Bulgarian (on-again, off-again) Orthodox Church, the mighty Czech Orthodox Church, etc., whether it be "who's the first" in the Orthodox world, whether it be "inclusive" freaks, etc. -- it all boils down to one and the same thing: we are no better than any other church but we like to act holier than thou!
Yet, Orthodoxy teaches us that this is not what we should do; rather we should point the finger of blame first and foremost on ourselves, because although we say we are first among the sinners, we really don't believe it for one moment. We certainly don't act as such!
False humility is the one most prominent feature of many a Christian. But, Faith must be shown through deeds ("works"), as +James says, and not only in words. I have stayed away form any particular parish, "denomination," or church politics for a long time. The more I approach the Church the uglier it gets. Hypocrisy is alive and well. Everything seems to define Orthodoxy nowadays except Orthodoxy! Whether it be ethnic pride (what are we proud of -- pride is a sin!), whether it be self-importance; whether it blaming others; whether it be power-grabbing, etc. none of this is Orthodoxy.
We have not only much work ahead of us; we are still at the start line. Shame on us all!
