There wasnt an agreed upon New Testament until over 300 years after Jesus ascended to heaven. So what did the faithful do without their King James Bible?"
The Bible, my FRiend, began with Moses penning the Penteteuch. Unless your cultish crowd wants to end run Moses, I'd say you are about 1500 years late. Paul did not have anything to do with Rome, and even noted that when he wrote to the believers there, he had never visited the place. The only reason he ended up there was due to appealing to Caesar to save himself from the Jews. Your group may wish to read some history books without the party line.
If he had nothing to do with them, why was he writing them a pastoral letter?
