Well yes that is your opinion. However, in fact the Orthodox Christian Church in Ukraine in communion with Moscow is finally growing stronger thanks to standing firm against the secularists in the so called west.
In Ukraine this is a question of Ukrainian nationhood, not secularist sympathies, and it is clear that the Ukrainian nation, weighing the pluses and minuses, prefers Europe to Putin.
In my opinion, MP is precisely the Soviet Orthodox Church, and so naturally the Soviets in the Ukraine would probably stick with Gundyaev. The unified Russian Orthodox Church does not exist anymore, except for some Orthodox splinters of ROCOR.
