Regarding Irenaeus as quoted by Mungo in this forum:
Here is what Mungo posted:
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 pre-eminent authority, that is, the faithful everywhere, inasmuch as the apostolical tradition has been preserved continuously by those [faithful men] who exist everywhere. (Against Heresies, Bk 3, Chap 3 [AD 180]
Yes, Ireneaus claimed that the Roman church was founded by both Peter and Paul. Obviously, he was wrong, as Paul wrote to an existing Roman church before he travelled to it….and in the salutation portion of that letter (Romans), Paul never mentioned Peter.
One should also note what Irenaeus said and didn’t say about why he considered Rome of special importance:
1. He did NOT say that Rome was special because Peter was its first bishop (he never claims that either Paul or Peter was a bishop of Rome) …instead Irenaeus indicated that Linus was appointed as bishop by the 2 apostles.
2. He did NOT say that Rome was special because it possessed the office of the Pope…. instead Irenaeus indicated that it was special because
the true faith was preserved through the succession of bishops. Please note that it is the life-giving faith that he names as being preserved by succession and not some Papal office.
3. He did NOT say that Rome was special because it possessed the keys given to Peter…instead Irenaeus stated that it was special because the 2 most glorious apostles founded it and then gave the greatest possible witness (martyrdom) at Rome.
Even though the opportunity presented itself again and again, Irenaeus never gave any indication that Rome had any papal office.
Further, Irenaeus indicated that both Paul and Peter appointed Linus. Peter and Paul are categorized as apostles (not bishops) making Linus the first bishop of Rome in Irenaeus’ mind. On this point Irenaeus disagreed with what is reported by both Tertullian and Jerome; in that the Latins (at their respective times) viewed Clement as the first person appointed by the apostles. It seems that the ancient traditions (regarding who occupied the bishopric of Rome) are confused…. which makes sense if a monarchial bishop wasn’t in place in Rome until the middle of the 2nd century.
Here is how Bart Erhman sums up the evidence regarding the alleged first Bishops/Popes:
But who was the first bishop of Rome? According to the second-century Irenaeus, it was a man named Linus, who was appointed to the office by Peter and Paul (Against Heresies 3, 3, 3). In one place the father of church history, Eusebius, appears to agree with this, to some extent, when he says that “the first to be called bishop after the martyrdoms of Peter and Paul was Linus” (Church History, 3, 2); but here Linus is appointed not by Peter, but by someone else, after Peter’s death. And to confuse things even further, just a few paragraphs later Eusebius phrases the matter differently, saying that “Linus … was the first after Peter to be appointed Bishop of Rome. Clement again, who became the third Bishop of Rome….” This makes it appear that Peter was the first bishop, Linus the second, and Clement the third. And the tradition becomes yet more confused when we consider the writings of Tertullian from the early third century, who seems to indicate that Clement was not the third bishop of Rome, but the first – appointed by Peter himself (Prescription of the Heretics 32)
Now you might not like Erhman’s theology, but here he is just talking history. The confusion and inconsistency of the early church fathers does not suggest that they were presenting anything approaching solid evidence.
In summary, my position on the early lists for the bishopric of Rome is:
a. The lists were not produced until well after the fact;
b. The lists that we possess disagree on vital details;
c. As such, this evidence is far from being rock solid; and
d. The problems with that evidence are so substantial that the scholarly consensus is properly aligned against accepting that evidence (as the consensus holds that Rome did not have a monarchical bishop until about 150AD)…and again, please note (that at this time in the history of the church) it is about lists for the bishopric of Rome (without envisioning a Papal office founded on that bishopric).
