The Son of God is back on Earth and starring on American Pop Star.      God takes a look at the Earth around the time of the Renaissance and everything looks pretty good - so he takes a holiday. In Heaven-time this is just a week's fishing trip, but on Earth several hundred years go by. When God returns, he finds all hell has broken loose: world wars, holocausts, famine, capitalism and Christians. Everywhere. There's only one thing for it. They're sending the kid back.      JC, reborn, is a struggling musician in New York City, trying to teach the one true commandment: Be Nice! His best chance to win hearts and minds is to enter American Pop Star. But the number one show in America is the unholy creation of a record executive who's more than a match for the Son of God...
