Part 1: Written and presented by leading British writer Howard Jacobson. Himself a Jew, Jacobson examines the origins and consequences of Christian belief and argues that, although Christianity originated in devout Judaism, for Jews, it has been, for the most part, a calamity.
Jacobson talks to Christian and Jewish scholars. He visits Jerusalem, Bethlehem, Galilee and Rome to find out more about Jesus, the Jew. He looks into how key Christian beliefs - including the notion of a Messiah and baptism - have roots in Judaism.
Furthermore, he asserts that Jesus didn't intend to start a new religion, that for Jesus's family - all Jewish - the new movement remained within Judaism: for them he was a charismatic Rabbi.
