THE JUDAS NOVEL by Archer and Moloney is already being parodied (in the Guardian). Excerpt:

Chapter 3

1. The treacherous Scribe tried to get Judas to betray Jesus, but he refused.

2. Judas understood the writings of Ezekiel far better than Jesus and the other disciples, but they didn't want to listen. So they never understood the true meaning of the Son of Man.

3. Judas also tried to tell the disciples what Jesus had meant by, "Get thee behind me, Satan." But they did not want to learn the subtleties of ancient Aramaic so Judas said unto them: "Verily, it is your loss."

Verily, verily.
