Dear brother Alex,
What an awesome explanation of the situation!
I was not aware of how ancient Kiev’s status as a “major archbishopric” was! Certainly, I agree that the UGCC has a right to patriarchal status (as already indicated in an earlier post in this thread and from past threads). The history you have given here has me even MORE convinced of the matter!

GOOD JOB! It seems to me that the Church in Ukraine should have had Patriarchal status long ago, even before its union with Rome, and it has only been Moscow’s Absolutist Petrine tendencies that has prevented its administrative independence.
I do believe that the situation should be corrected. And I certainly do believe that the bishop of Rome has the authority - and obligation - to correct this situation.
But (sorry for the “but”

),
how this is to be done is the hard part, and I still retain my ambivalence on that particular matter. History shows that patriarchal status has been granted to particular Churches -
but this has only been done by an existing Patriarch for members of his OWN particular Church - i.e., within his patriarchal jurisdiction or Tradition (e.g., Antioch for Georgia, Alexandria for Ethiopia, Rome for Venice, etc., etc.). Do you see the potential problem here? The fact is,
Rome is not the mother Church of the Ukranians. On the
patriarchal level, only Moscow would have the authority to grant autocephaly to the Ukranians - obviously ain’t gonna happen.
But the Catholic Church recognizes that there an authority in the Church militant that is even higher than patriarchal authority. It is this higher, universal authority that can grant patriarchal status across particular Church boundaries/jurisdiction. We recognize and accept a universal supreme authority in three forms: (a) the papacy, (b) the Ecumenical Council, and (c) the body of bishops around the world even when dispersed when they are united on an issue.
The Ecumenical Council would admittedly be an unrealistic avenue to pursue for this matter.
The other two avenues are more practical, and it is these that I have proposed earlier in this thread. Avenue (c) can be pursued by
first getting the support of patriarchs and primates from other Churches before approaching the bishop of Rome.
As far as avenue (a), we know that the Pope can exercise his supreme authority either personally or collegially. From the standard of the first millenium Church (which I assume we all want), I see that the Pope can only do this in a collegial fashion. In this regard, I proposed that the UGCC approaches the Pope, and he can call a special Synod for the determination of the matter. I did say earlier in the thread that I could not see why the Pope would call a special synod
just for the matter of granting patriarchal status. But, as stated earlier in this post, the history you have just given has me convinced that such a special synod is well-deserved, for it has me thinking that the Church in Ukraine has not had patriarchal status because of an
unjust motive by the Church in Moscow.
Having said all that, I must openly admit that I don’t believe the UGCC has a
right to patriarchal status. I think the only Churches that have a
right to patriarchal status are the ones established by the Ecumenical Councils of the first millenium. I believe the UGCC deserves patriarchal status on the basis of JUSTICE and FAIRNESS.
