in the dome over st. peters. it is at the core of roman catholicism. >> did peter really travel to rome to lay the foundations for the catholic church? >> the new testament says nothing explicitly about peter coming to rome and i think a lot of people will be surprised to find this out. >> the apostle paul who we know lived in rome and whose letters make up half of the new testament doesn't refer to peter being in the city once. >> he doesn't seem to know of him. he doesn't mention any connection between the christians there in the city and peter and that's kind of interesting omission. so if peter is there in the city, why doesn't paul say anything about him at all? >> the omission is all the more strange because we know peter and paul knew each other. >> in and around a.d. 50 peter and paul meet at antioch. they meet there because peter has come from jerusalem to see the progress being made by paul's mission. >> my brother.
