As requested by many , I have started a new thread. I will do my best to stay on topic here. In one of my prior post (concerning the All-sufficiency of the scriptures) I quoted Augustine’s self correction on Matt. 16:18. The quote was found initially in "Philip Shaff’s ,History of the Christian Church. I was asked to provide the exact Augustine source. After confering with one of my brothers in Christ he located it for me. I provide it here as a starting point to this post.
Augustine ( 430), the greatest theological authority of the Latin church,at first referred the words, ÒOn this rock I will build my church,Ó to the person of Peter, but afterward expressly retracted this interpretation, and considered the petra to be Christ, on the ground of a distinction between petra (ejpi< tau>th| th~| pe>tra|) and Petrus (su< ei+ Pe>trov); a distinction which Jerome also makes, though with the intimation that it is not properly applicable to the Hebrew and Syriac Cephas.f564 ÒI have somewhere said of St. PeterÓ thus Augustine corrects himself in his Retractations at the close of his lifef565ÑÓthat the church is built upon him as the rock; a thought which is sung by many in the verses of St. Ambrose:ÕHoc ipsa petra ecclesiae Canente, culpam diluit.Õf566 (The Rock of the church himself In the cock-crowing atones his guilt.)But I know that I have since frequently said, that the word of the Lord, ÕThou art Petrus, and on this petra I will build my church,Õ must be understood of him, whom Peter confessed as Son of the living God; and Peter, so named after this rock, represents the person of the church, which is founded on this rock and has received the keys of the kingdom of heaven. For it was not said to him: ÕThou art a rockÕ (petra), but, ÕThou art PeterÕ (Petrus); and the rock was Christ, through confession of whom Simon received the name of Peter. Yet the reader may decide which of the two interpretations is the more probable.Ó In the same strain he says, in another place: ÒPeter, in virtue of the primacy of his apostolate, stands,by a figurative generalization, for the church .... When it was said to him, ÕI will give unto thee the keys of the kingdom of heaven,Õ &c., he represented the whole church, which in this world is assailed by various temptations,as if by floods and storms, yet does not fall, because it is founded upon a rock, from which Peter received his name. For the rock is not so named 246 from Peter, but Peter from the rock (non enim a Petro petra, sed Petrus a petra), even as Christ is not so called after the Christian, but the Christian after Christ. For the reason why the Lord says, ÕOn this rock I will build my churchÕ is that Peter had said: ÕThou art the Christ, the Son of the living God,Õ On this rock, which then hast confessed, says he will build my church. For Christ was the rock (petra enim erat Christus), upon which also Peter himself was built; for other foundation can no man lay, than that is laid, which is Jesus Christ. Thus the church, which is built upon Christ, has received from him, in the person of Peter, the keys of heaven; that is, the power of binding and loosing sins.Óf567 I found It interesting as well , that St. Jerome and St. Ambrose were mentioned as sharing the same belief.
Thanks again for your patience,
