That said, I do accept, besides taking it, your point. It could in general be that three statements might appear harmonius, yet being two false and one true, or vice versa.
But what i repeat in our own case is that ECFs do not speak about harmony. They collectively state the three readings of petra. Each of the three is stated as sound. None of them is object of exclusion, attack.
If these men were wise, then the modern exclusion of Petros=petra, with all those broadsides against it, does not appear wise.
IMHO what helps us more is the thrust of the ECFs , rather than single passages. But if you ask for a single quotation providing food for thought, we could maybe try with;
Sermon 26 ( or 76, in other lists) by St Augustine
" For Peter in the order of Apostles first, and in the love of Christ most forward, answers oftentimes alone for all the rest. Again, when the Lord Jesus Christ asked, whom men said that He was, and when the disciples gave the various opinions of men, and the Lord asked again and said, “But whom say ye that I am?” Peter answered, “You are the Christ, the Son of the living God.” One for many gave the answer, Unity in many. Then said the Lord to Him, “Blessed are you, Simon Barjonas: for flesh and blood has not revealed it unto you, but My Father which is in heaven.” Then He added, “and I say unto you.” As if He had said, “Because you have said unto Me, ‘You are the Christ the Son of the living God;’ I also say unto you, ‘You are Peter.’” For before he was called Simon. Now this name of Peter was given him by the Lord, and that in a figure, that he should signify the Church.
"For seeing that Christ is the rock (Petra), Peter is the Christian people. For the rock (Petra) is the original name. Therefore Peter is so called from the rock; not the rock from Peter; as Christ is not called Christ from the Christian, but the Christian from Christ. ‘Therefore,’ he saith, ‘Thou art Peter; and upon this Rock’ which Thou hast confessed, upon this rock which Thou hast acknowledged, saying, ‘Thou art the Christ, the Son of the living God, will I build My Church;’ that is upon Myself, the Son of the living God, ‘will I build My Church.’ I will build thee upon Myself, not Myself upon Thee.
(Philip Schaff, Nicene and Post-Nicene Fathers ( this central part is the one often quoted by non catholic brothers).
…
- This same Peter therefore who had been by the Rock pronounced “blessed,” bearing the figure of the Church, holding the chief place in the Apostleship, a very little while after that he had heard that he was “blessed,” a very little while after that he had heard that he was “Peter,” a very little while after that he had heard that he was to be “built upon the Rock,” displeased the Lord…
- …Yet see this Peter, who was then our figure; now he trusts, and now he totters; now he confesses the Undying, and now he fears lest He should die. Wherefore? because the Church of Christ has both strong and weak ones; and cannot be without either strong or weak; whence the Apostle Paul says, “Now we that are strong ought to bear the infirmities of the weak.” In that Peter said, “You are the Christ, the Son of the living God,” he represents the strong: but in that he totters, and would not that Christ should suffer, in fearing death for Him, and not acknowledging the Life, he represents the weak ones of the Church. In that one Apostle then, that is, Peter, in the order of Apostles first and chiefest, in whom the Church was figured, both sorts were to be represented, that is, both the strong and weak; because the Church does not exist without them both."
We have here IMHO that
- in teaching that Christ is to be considered the Petra and Petros is so called from Christ, and built on Christ ( which is beautiful BTW, IMHO)
- in teaching that Peter is the type of the One Church (same as above, IMHO) …
Augustine teaches us petrine primacy.
Repeatedly and clearly.
And teaches that it is a primacy in love. And that it is a very real primacy, not just a matter of place of honor. “Chief place” of New Advent translates “principatus”. This is a strong word for a primacy. It can look like “rule”, “supremacy”.
Many people, quoting out of context the central passage, suppose and let suppose that this sermon by Augustine …disproves petrine primacy !
We could also see a famous passage stating petra=Peter’s confession.
