1 want proof outside your Catholic tradition. Does Scripture say that St. Peter was ever in Rome?

The Catholic Answers

Catholic tradition is not a mere matter of rumor and report. It is down in black and white in documents as historical as any other documents, beginning from the year 97 with the declaration of the fact by Clement. It would not matter if Scripture did not give any evidence on this point. However it does. St. Peter ends his first Epistle with the words, “The Church which is in Babylon salutes you, and so doth my son, Mark.” All reputable scholars admit that the first Christians called pagan Rome Babylon on account of its vices. St. Peter, therefore, was writing from Rome. St. Paul wrote to the Colossians from Rome, sending the kind wishes of Mark, thus also indicating Mark’s presence in Rome.
