[Cronos]

In reality, the apostle to the Gentiles as described by Peter and the others in Jerusalem was Paul, not Peter.

There were expatriate Jews all over the world. They are and have always been an enterprising people (remember that Jews were key bureaucrats even in the Persian Empire and even in the later Muslim Empires). There were Jewish communities in Alexandria (Egypt), and the one in the Elephantine island on the Nile were there for centuries. There were Jewish communities in the Centre of the Roman Empire -- Rome. Why, there were even Jews in India (Cochin) -- where St. Thomas (doubting Thomas) went to preach.

True. I'm not denying he was in Rome. It's just that the gentile church took off while the Jewish one still has not and will not until, as Paul described it, the full number of gentiles have come in (Romans 11:25).
