“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)
