Did anyone see the program on the National Geographic channel - Science of the Bible-Rivals of Jesus?
Here is a description taken from their website:
Science of the Bible
Rivals of Jesus 
Science of the Bible examines those competing faiths and rival prophets that challenged early Christianity, such "lost" Messiahs as Mithras, Simon Magus, and Apollonius of Tyana. Some of these Messiahs and their faiths were once more popular than Christianity but their beliefs and practices were borrowed from the growing Christian movement. With historical re-enactments and interviews with Biblical scholars, theologians and historians, Rivals of Jesus presents a lost chapter of religious history.
Some of the stuff presented I was not aware of. It was a very eye opening program.
One of the things brought out was something I was aware of, that being Constantines decision to promote Christianity because he saw a cross in the sky. If that hadn't of happened (even if it was just in his imagination) I don't think there would be Christianity as we know it today. And to think the JW's base their beliefs on something that was so heavily influenced by a cross.
