Peter was never in Rome.....and in fact, was told to stay out of there! [Matthew 10:5-6] These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel.
Like the article said.....that's why The Lord chose Paul.
Well, Ignatius of Antioch died in AD 110. He personally knew both Peter and Paul, and knew at least Polycarp of Smyrna, who was a disciple of John, if he didn't also know John personally.
Ignatius refers to the Romans being "commanded" by Peter and Paul in his Epistle to them. If anyone would know, he would.
Then there is the archaeological evidence surrounding Peter's tomb underneath the high altar of the basilica. It's clearly a site that was venerated by Christians going back well before Constantine. It's kind of hard to spin graffiti reading Petros eni ("Peter is within").
The usual argument is that Peter went to "Babylon". Ask an Iraqi Christian -- Catholic or Orthodox or Nestorian -- who founded the Church in Iraq. They won't say "Peter". If he had been there, the Christian community in that part of the world (most of which has not been under Roman rule for centuries) would be extremely proud of it.
If you scroll down a ways (quite a ways), you'll find one of the more interesting bits of evidence: on a tomb, in the Vatican necropolis near (what is believed to be) St. Peter's tomb, is the inscription:
Peter, pray for the holy Christian men buried near your body
The tomb dates no later than AD 192.
There were “gentile “ cities in Galilee near Nazareth and others on Lake Galilee, and to the west of Galilee on the seacoast. Samaria was south of Galilee, between it and Judea. This was, after all, during his Galilean ministry.
Oh, no, not this argument again. You were proven wrong once; why do you persist in re-presenting your erroroneus thoughts?
