Catholic Church
"... thou art Peter and upon this rock I will build my Church ...It is on him that He builds the Church, and to him that He entrusts the sheep to feed. And although He assigns a like power to all the apostles, yet He founded a single Chair, thus establishing by His own authority the source and hallmark of the (Church's) oneness...If a man does not fast to this oneness of Peter, does he still imagine that he still holds the faith. If he deserts the Chair of Peter upon whom the Church was built, has he still confidence that he is in the Church?"
