Why are you hung up on Rome?
Exactly when did Peter move shop and set up headquarters in Rome? Do you have an approximate date?
Very approximate. Does it matter to you? When did 2 Peter get written? When did the Comma Johanneum get written? When did the Trinitarian formula in Matthew 28 get written?
Because it’s very important to know when Peter moved to Rome and set up shop. And yes, it matters to me. I don’t want to ASSUME that it was in 61-65 A.D., when 2 Peter was written. But I would rather ask someone who has a very approximate date than guess.
