Does this passage contradict RC teaching on Peter and the Rock?
(Post-Nicene Fathers, Volume IX, Book VI; St. Hilary of Poiters)
"What then is this truth, which the Father now reveals to Peter, which receives the praise of a blessed confession? It cannot have been that the names of ‘Father’ and ‘Son’ were novel to him; he had heard them often. Yet he speaks words which the tongue of man had never framed before:–Thou art the Christ, the Son of the living God. For though Christ, while dwelling in the body, had avowed Himself to be the Son of God, yet now for the first time the Apostle’s faith had recognised in Him the presence of the Divine nature. Peter is praised not merely for his tribute of adoration, but for his recognition of the mysterious truth; for confessing not Christ only, but Christ the Son of God. It would clearly have sufficed for a payment of reverence, had he said, Thou art the Christ, and nothing more. But it would have been a hollow confession, had Peter only hailed Him as Christ, without confessing Him the Son of God. And so his words Thou art declare that what is asserted of Him is strictly and exactly true to His nature. Next, the Father’s utterance, This is My Son, had revealed to Peter that he must confess Thou art the Son of God, for in the words This is, God the Revealer points Him out, and the response, Thou art, is the believer’s welcome to the truth. And this is the rock of confession whereon the Church is built. But the perceptive faculties of flesh and blood cannot attain to the recognition and confession of this truth. It is a mystery, Divinely revealed, that Christ must be not only named, but believed, the Son of God. Was it only the Divine name; was it not rather the Divine nature that was revealed to Peter? If it were the name, he had heard it often from the Lord, proclaiming Himself the Son of God. What honour, then, did he deserve for announcing the name? No; it was not the name; it was the nature, for the name had been repeatedly proclaimed.
- This faith it is which is the foundation of the Church; through this faith the gates of hell cannot prevail against her. This is the faith which has the keys of the kingdom of heaven. Whatsoever this faith shall have loosed or bound on earth shall be loosed or bound in heaven. This faith is the Father’s gift by revelation; even the knowledge that we must not imagine a false Christ, a creature made out of nothing, but must confess Him the Son of God, truly possessed of the Divine nature. What blasphemous madness and pitiful folly is it, that will not heed the venerable age and faith of that blessed martyr. . . The very reason why he [Peter] is blessed is that he confessed the Son of God. This is the Father’s revelation, this the foundation of the Church, this the assurance of her permanence. Hence has she the keys of the kingdom of heaven, hence judgment in heaven and judgment on earth. Through revelation Peter learnt the mystery hidden from the beginning of the world, proclaimed the faith, published the Divine nature, confessed the Son of God. He who would deny all this truth and confess Christ a creature, must first deny the apostleship of Peter, his faith, his blessedness, his episcopate, his martyrdom. And when he has done all this, he must learn that he has severed himself from Christ; for it was by confessing Him that Peter won these glories."
