This is so stupid an apology that it makes me think that you must have had a head injury. The Bible speaks many times on false prophets. Paul's message is clear. He asks his fellow Christians to test what other Christians said.
so ya he does not mention other religion, but with the Romans moving around it is obvious during that time what he was talking about,
No. It is not at all obvious. You may think
that there were other gods involved, but you have no proof whatsoever. You are just making things up. Basically you are telling lies to support Christianity.
not so much in this day and age because people tend to take this crap for what it means and not know any of the history of the writing.
As there are no original documents (http://www.religion-online.org/showarticle.asp?title=91#_Toc439066004
) and as Paul is believed to be, at best, the author of only seven of the [wiki]Pauline Epistles[/wiki], and, as there is scant proof that Paul was actually a real person, then as you say, we do " not know any of the history of the writing. "
By and large the Romans saw Christians of that time as harmless idiots - much as we do today.
