We already discussed that. There is certain room for interpretation of papal primacy, — from the Orthodox understanding of mere primacy of honor to the Catholic concept of papal supremacy in matters of faith and morals, that is in both cases in accordance with the consensus of the Fathers. As to the quotes about the Rock being Christ onto which the papacy is grafted, and about what matters is St. Peter’s confession rather than his person apart from his faith, — that is the Catholic view as well.
There's no evidence of it on FR!!!
