On this week's show (17 Jan 09) two New Testament scholars go head to head. Michael Bird is a believer, James Crossley is not. They have different conclusions about how the Christian faith began and have written a dialogue in their new book "How Did Christianity Begin - a believer and non-Believer examine the evidence".

In today's programme they debate whether Jesus himself beliived he was God, as revealed in the Gospels. They go onto discuss whether the bodily resurrection of Jesus is a plausible explanation for the birth of the early church.

"How did Christianity begin? A believer and non-believer examine the Evidence" is published by SPCK"
