There is so much that is better than good in the Declaration of Cuba that it seems churlish to carp. But ...
Paragraph 27: I find this enormously strange. Unless the Russian Church is finally conceding that the Bishop of First Rome does have a general supervision of All the Churches so as to maintain or to restore unity and to resolve disputes, I completely fail to see what on earth it has to do with the Pope what the competing Ukrainian Orthodox jurisdictions do. What standing has Rome to prescribe upon what basis in Canon Law Orthodox should reconcile among themselves? I can't help feeling that Moskow has tricked the Vatican into, rather unwisely, taking sides in an intra-Orthodox dispute. No fools, these Russkies.
Paragraph 25: If a group of Bishops with their Clergies and Peoples decide to seek formal links of Communion with the See of S Peter, I do not see upon what grounds of Catholic ecclesiology their request can be denied or rebuffed. Calling it Unia and then deeming that term to be a dirty word is just ecclesiastical spin-doctoring.
Could it be that Moskow is afraid that some of the Ukrainian Orthodox might seek shelter under a Roman, rather than a Muscovite, umbrella? Or is all this part of Moskow's unease that the Ecumenical Patriarchate might (as it has done before) take a 'primatial' hand in the canonical problems within the former Soviet Empire? Or do we have here a device to pre-empt some possible jockying at this year's Pan-Orthodox Conference? Did Cardinal Koch check with Constantinople that these texts were unexceptionable?
