I can find writers who talk about the church started by Peter AND Paul, if it was KNOWN for all ages that it was from Peter alone, why can’t you cite just 1?
The Catholic Church commemorates the Feasts of Peter and Paul on the same day. We have no problem with Paul’s role in the early development of the Church at Rome: none at all.
Has anyone cited Irenaeus of Lyons on this thread yet? *Adversus Haeresis, book iii. *Around 185-190 A.D.
Irenaeus first makes the case for the primacy of the Church at Rome based on its founding by both Peter and Paul, then goes on to list the first bishops, showing that Rome had maintained its purity and authority:
Since, however, it would be very tedious, in such a volume as this, to reckon up the successions of all the Churches, we do put to confusion all those who, in whatever manner, whether by an evil self-pleasing, by vainglory, or by blindness and perverse opinion, assemble in unauthorized meetings; [we do this, I say,] by indicating that tradition derived from the apostles, of
the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also [by pointing out]
the faith preached to men, which comes down to our time by means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its preeminent authority. . . .
The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate. Of this Linus, Paul makes mention in the Epistles to Timothy. To him succeeded
Anacletus; and after him, in the third place from the apostles,
Clement was allotted the bishopric. This man, as he had seen the blessed apostles, and had been conversant with them, might be said to have the preaching of the apostles still echoing [in his ears], and their traditions before his eyes. Nor was he alone [in this], for there were many still remaining who had received instructions from the apostles. In the time of this Clement, no small dissension having occurred among the brethren at Corinth,
the Church in Rome despatched a most powerful letter to the Corinthians, . . . From this document, whosoever chooses to do so, may learn that He, the Father of our Lord Jesus Christ, was preached by the Churches, and may also understand
the apostolical tradition of the Church, since this Epistle is of older date than these men who are now propagating falsehood . . .
Note that the letter of Clement was written within the lifetime of Apostle John. Catholics understand apostolic tradition from both Scripture and the actual practice of the early Church.
I recommend not only the passages of Scripture that demonstrate Peter’s primacy (Luke 18:31-320, Mt. 16:18-19, Jn 21) but also the third letter of John. It is all about: who are you? where did you get your authority? The early Church depended on knowing who preached the Gospel to you. Anyone not attached to an apostolic source was considered unreliable, and likely a heretic.
