Brown, Raymond E. & Meier, John P. (1983). Antioch and Rome: New Testament Cradles of Christianity. Paulist Press. str. 98. ISBN978-0-8091-0339-3. »As for Peter, we have no knowledge at all of when he came to Rome and what he did there before he was martyred. Certainly he was not the original missionary who brought Christianity to Rome (and therefore not the founder of the church of Rome in that sense). There is no serious proof that he was the bishop (or local ecclesiastical officer) of the Roman church—a claim not made till the third century. Most likely he did not spend any major time at Rome before 58 when Paul wrote to the Romans, and so it may have been only in the 60s and relatively shortly before his martyrdom that Peter came to the capital.«
