“Jesus answered him, Blessed art thou, Simon son of Jona; it is not flesh and blood, it is my Father in heaven that has revealed this to thee. And I tell thee this in my turn, that thou art Peter, and it is upon this rock that I will build my church… From that time onwards Jesus began to make it known to his disciples that he… must be put to death, and rise again on the third day. Whereupon Peter… began remonstrating with him; Never, Lord, he said; no such thing shall befall thee. At which he turned round and said to Peter, Back, Satan; thou art a stone in my path; for these thoughts of thine are man’s, not God’s…” (St. Matthew xvi, 16-18, 21-24)

“The Roman Pontiff – like all the faithful – is subject to the Word of God, to the Catholic faith, and is the guarantor of the Church’s obedience; in this sense he is servus servorum Dei. He does not make arbitrary decisions, but is spokesman for the will of the Lord, who speaks to man in the Scriptures lived and interpreted by Tradition; in other words, the episkope of the primacy has limits set by divine law and by the Church’s divine, inviolable constitution found in Revelation.” (Congregation for the Doctrine of the Faith, “The Primacy of the Successor of Peter in the Mystery of the Church”, quoted by Bishop Athanasius Schneider)
