And?Not only was this written by a man who lived before the Great Schism - and who later in life changed his mind about the person of Peter being the Rock upon which the Church is founded
Only since Vatican II, which is my point. Vatican II taught a false New Ecclesiology that is completely at odds with the traditional Catholic teaching. Veneration of Gregory Palamas as a “saint” was forbidden before Vatican II, by the way.- but the existence of the Uniates proves that the "Roman Catholic Church" does not even really believe in its own ecclesiology. They are in full communion with people who venerate St. Gregory Palamas as a Saint (as they should), so it seems they will be in communion with anyone who professes submission to the Pope even if that person believes in things that they aren't "supposed to."
