In his first papal encyclical he designated Rome under a symbolic name well understood by his fellow Jews: “She who is at Babylon, who is likewise chosen, sends you greetings” (1 Pet. 5:13). Jews would readily recognize their ancient persecutor, Babylon, largely in ruins, the allusion to their contemporary ruler, Rome. Recognition became easier when St. John gave them a broad hint; “Babylon the great . . . seven hills” (Apoc. 17:5-9) an allusion to Rome’s famous seven hills. But if explicit identification be required, Clement of Alexandria gives it about 200 A.D. Clement, who would be well aware of the existence of another small town near Alexandria, Egypt, named Babylon, yet asserts: “Peter makes mention of Mark in his first Epistle which they report he wrote in Rome. as he indicates where he calls the city figuratively Babylon” (Clement, Hypotyposes, cited by Eusebius, History, II, 15).
THE CHURCH AT ROME
But Peter was not merely a visitor in Rome. He was the founder of the church of Rome, that is, the organizer of the Christian hierarchy there, its first bishop. For St. Clement of Rome, a disciple of the Apostles mentioned by St. Paul (Phil. 4:3), affirmed that both Peter and Paul suffered martyrdom “among us,” that is, in Rome, where Clement was writing about 96 A.D.
St. Ignatius of Antioch (35-107 A.D.), yet takes Peter’s Roman commitment for granted: “I do not command you as Peter and Paul did; they were Apostles;” (Letter to Romans, 4). St. Denis, Bishop of Corinth, was even more emphatic: writing to a later Pope, St. Soter, he asserted, “By this admonition you have bound together the plantings of Peter and Paul at Rome and at Corinth. For they both alike planted in our Corinth and taught us, and both alike taught together in Italy and suffered martyrdom at the same time” (Eusebius, History, II, 25).
St. Irenaeus (about 130-200 A.D.), Bishop of Lyons explicitly affirmed both that St. Peter had founded the church of Rome, that its bishops were his successors, and that to this church all other churches ought to be subordinate. His assertion, issued as a challenge to contemporary gnostic heretics who pretended to “inside knowledge” from the Apostles, is this: “By indicating the 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, and the faith preached to men which comes down to our time, by means of the succession of bishops, we refute all persons . . . for to this church, on account of its more potent principality, it is necessary that every other church agree, that is, those of the faithful everywhere, because in it is preserved by those (who preside) that tradition received from the Apostles. The blessed Apostles, then, founded and reared up this church and afterward committed unto Linus the office of the episcopate” (Against Heresies, III, 3, written by St. Irenaeus).
