St Peter
Simon, son of Jonah, was a fisherman of Bethsaida and Capernaum on the Sea of Galilee, the brother of Andrew, when Christ called him from his nets and gave him a new name: 'Thou shalt be called Cephas, which is interpreted Peter' — the Rock. From that moment he stands first among the Twelve: every list of the Apostles names him first and Judas last, and it is Peter who speaks for the others, walks on the water, is taken up the mountain of the Transfiguration, and at Caesarea Philippi confesses, 'Thou art Christ, the Son of the living God.' To that confession Christ answers with the charter of the papacy itself.
He was not a marble saint but a man — impetuous, generous, and frail. He swore he would never deny his Master and then denied Him three times before the cock crew, and 'going forth, he wept bitterly.' Yet the Risen Christ sought him out by the lakeside, drew from him a threefold love to answer the threefold denial, and gave him the universal charge: 'Feed my lambs... Feed my sheep.' At Pentecost it is Peter who stands and preaches the first sermon of the Church; he works its first miracle, speaks for the Apostles before the Sanhedrin, opens the door of the Church to the Gentiles in the house of Cornelius, and rises first to settle doctrine at the Council of Jerusalem.
His charter is Matthew 16:18-19: 'Thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. And I will give to thee the keys of the kingdom of heaven; and whatsoever thou shalt bind upon earth, it shall be bound also in heaven.' The rock, the keys, the power to bind and loose — given to Simon alone, and given by the Son of David who was building His Kingdom. The keys are no accident of phrase: they reach back to Isaiah 22, where the steward of the house of David bears 'the key of the house of David upon his shoulder,' a royal office of governance that passes from one holder to the next as long as the kingdom stands.
He came at last to Rome, the heart of the empire, and there shepherded the Church and there died. Under the persecution of Nero, around the years 64 to 67, Peter was crucified — head downward, by the tradition Origen preserved, counting himself unworthy to suffer as his Lord had — and was buried on the Vatican Hill, where a shrine marked his grave by the year 200 and where the basilica that bears his name still rises over his bones. He is the first Pope, the first Vicar of Christ; his Chair endures, and the Church keeps its feast on 22 February.
To Simon the fisherman, Christ said: 'Thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it' (Matthew 16:18). The Church has never read those words as an idle compliment. From the second century onward — long before any council defined the papacy — the Fathers of East and West, the martyrs and bishops and doctors, saw in Peter the rock, the holder of the keys, the chair in which the unity of the whole Church is kept. Here is the witness of the ancient and undivided Church, in its own words.
Every list of the Apostles begins with his name; every list of the Popes begins with him. He is the rock on which Christ built His Church, the first to hold the keys, the first Vicar of Christ — and the whole question of the papacy is, at bottom, the question of what Christ meant when He looked at a Galilean fisherman and called him Rock.
He meant a great deal. To Simon alone, and to Simon by a new name, He said: 'Thou art Peter, and upon this rock I will build my church... I will give to thee the keys of the kingdom of heaven.' Three gifts, given singly and by name — the rock that founds, the keys that govern, the power to bind and loose that judges. No other Apostle is renamed Rock; to none other are the keys handed; for none other does Christ pray by name 'that thy faith fail not,' charging him to 'confirm thy brethren.'
And the keys are not a stray metaphor. They reach back through the whole story of Israel to Isaiah 22, where the steward of the house of David carries 'the key of the house of David upon his shoulder,' with power to open and shut in the king's name. On the Catholic reading, that stewardship was a standing office of the Davidic kingdom, passed from one holder to the next as long as the throne endured. Christ, hailed everywhere as the Son of David, builds His everlasting Kingdom — the Church — and appoints His steward, handing Peter the keys. As the Old-Covenant office did not die with its holder but passed to a successor, so neither does the office of the keys: the King provides another steward, and the chair endures. This is why the papacy is a continuing office and not merely the personal honour of one fisherman.
We do not hide the objections; we answer them. That the 'rock' is only Peter's confession founders on the Aramaic Christ actually spoke, where Peter and the rock are one word, and on a sentence addressed throughout to Peter himself. That Paul rebuked him at Antioch is true — and beside the point: it was a rebuke of conduct, not of doctrine, and the office of Peter no more requires his impeccability than the office of a king requires that he never sin. The rock was a man who wept after his denial; the wonder is not that he failed, but that Christ built on him anyway.
And the Church of the first centuries knew it. We have just heard them — Irenaeus and Cyprian, Jerome and Optatus, Augustine and Ambrose, Chrysostom of the East, and the assembled bishops of Chalcedon — naming Peter the rock, the chair, the head of the apostolic choir, the see in which unity is kept. This is no medieval overreach; it is the faith of the ancient and undivided Church. Peter came to Rome, shepherded the flock, and died on the Vatican Hill — crucified, by ancient tradition, head-downward, counting himself unworthy to suffer as his Lord had. A shrine marked his grave by the year 200, and the basilica that bears his name rises over the tomb the Church has always venerated as his. His Chair is still there. And the gates of hell have not prevailed.
