All the hulabaloo about the Da Vince Code has reminded me of a SF short story I read at least 30 years ago.
It was about a press agent who met this fellow in Nazareth that had cured several people. It proceeded to relate how the PR guy instructed the fellow and his 11 partners on starting a religion. Very tongue in cheek, but very funny and interesting.
I would love to find the story again.
