This story makes The Da Vinci Code look like child's play.

Judas, My Brother is a fictional story about the time of Jesus.  Jesus is portrayed as a bumbling idiot who couldn't put his sandals on straight.  In fact, all the alleged miracles accredited to Jesus were really performed by a Jesus lookalike who actually performed all the acts in question.  The problem is that the actions weren't miracles at all, but actions of the lookalike using his common sense.
