Augustine
And I tell you…‘You are Peter, Rocky, and on this rock I shall build my Church, and the gates of the underworld will not conquer her. To you shall I give the keys of the kingdom. Whatever you bind on earth shall also be bound in heaven; whatever you loose on earth shall also be loosed in heaven’ (Mt 16:15-19). In Peter, Rocky, we see our attention drawn to the rock. Now the apostle Paul says about the former people, ‘They drank from the spiritual rock that was following them; but the rock was Christ’ (1 Cor 10:4).
So this disciple is called Rocky from the rock, like Christian from Christ…Why have I wanted to make this little introduction? In order to suggest to you that in Peter the Church is to be recognized. Christ, you see, built his Church not on a man but on Peter’s confession. What is Peter’s confession? ‘You are the Christ, the Son of the living God.’ There’s the rock for you, there’s the foundation, there’s where the Church has been built, which the gates of the underworld cannot conquer (John Rotelle, Ed., The Works of Saint Augustine (New Rochelle: New City Press, 1993), Sermons, Vol. 6, Sermon 229P.1, p. 327).
"In a passage in this book, I said about the Apostle Peter: ‘On him as on a rock the Church was built’…But I know that very frequently at a later time, I so explained what the Lord said: ‘Thou art Peter, and upon this rock I will build my Church,’ that it be understood as built upon Him whom Peter confessed saying: ‘Thou art the Christ, the Son of the living God,’ and so Peter, called after this rock,
represented the person of the Church which is built upon this rock, and has received ‘the keys of the kingdom of heaven.’ For, ‘Thou art Peter’ and not ‘Thou art the rock’ was said to him. But ‘the rock was Christ,’ in confessing whom, as also the whole Church confesses, Simon was called Peter.
But let the reader decide which of these two opinions is the more probable (The Fathers of the Church (Washington D.C., Catholic University, 1968), Saint Augustine, The Retractations Chapter 20.1).
Augustine lets the reader decide what this foundational verse means?
What no universal understanding in the 5th century that this verse creates the papacy?
Did’nt Vatican I anathematise any other understanding?
“If anyone, therefore, shall say that blessed Peter the Apostle was not appointed the Prince of all the Apostles and the visible head of the whole church militant; or that the same directly and immediately received from our Lord Jesus Christ a primacy of honor only, and not of true and proper juridition: let him be anathema.”
I will take up Augstine’s offer of using my “private interpretation” and go with peter’s confession as the Rock
