Also, here's my opinion on the Gadolig Church :DD, from another thread.
Tbh, as an Orthodog, I'm one of the few people who have no issues with the filioque or even with papal infallibility. Wwell, while I think they're heresies, they only attempt to describe very real doctrines of the early Church, they just do it in a very biased way due to the Pope not seeking counsel from us, and they just need some reworking (which in fact is pretty much already done for the filioque, there only needs to be a conciliar statement that puts it the exact way we Orthodox mean it, and we need to return the favor by respecting the Latin doctrine as correct if not clumsily expressed before).
What bothers me is the countless contradicting dogmatic statements of the Catholic Church. Of course, technically speaking they do not contradict, but anybody without a major bias can see that it is because theologians have used major mental gymnastics to concord newer doctrines with older ones.
For one evident example: compare Unam sanctam and Cantate domino to Lumen gentium. Indeed, Vatican II is extremely difficult to reconcile with earlier dogmatic statements. However, at the same time, it's extremely difficult to reject Vatican II due to what Vatican I says about the authority of the Pope.
The liturgical mess that is the Catholic Church today, even for many Eastern Catholics, is only the cherry on the top, of course…
But, I also recognize that there is no real "killer argument" against Catholicism. They're technically correct on every account. In the end, what makes one decide between Orthodoxy and Catholicism is not how correct they are, but what one expects the One, Holy, Catholic, and Apostolic Church to look like. Is the main form of authority collegial or monarchical? Do the Latin Fathers need to be understood in light of the earlier and more terminologically accurate Greek Fathers, or do the Greek Fathers need to be understood in light of the later and more theologically elaborate Latin Fathers? Most importantly, who carried the torch of being the Church when the Great Schism happened (and by "Great Schism" I don't mean 1054, but the period from 1013 to the end of the 4th Crusades)?
This is what I will say: I, with St. Gregory Palamas, agree that Peter is the rock on which the Church was built. He is the source of unity of all the episcopate, as St. Cyprian of Carthage believed, and although many sees are apostolic, and many bishops are direct successors of St. Peter (see Antioch, and see today all the churches that claim apostolicity from Antioch), the title of Apostolic See and of Vicar of Peter is specifically reserved for Rome due to it being the presiding Church, who in particular saved the East's ass many times in the first millenium due to being untouched by the need to express the received tradition in philosophical terms. And I also believe, that the prayer of our Lord - that Peter would strengthen the faith of his brothers - also applies to his successors, and specifically so to the Pope due to him being recognized as Peter's main successor.
