Quote:
revealed not by the disciples because they were too incompetent
As literary characters, the apostles are stooges. Their incredulous response to the first miracle is the same as their incredulous response to every other miracle.

Real people, at some point, would have at least started to accept that Jesus could do anything he said he was going to. Like Cleese's character: You're the real thing, a true messiah, and i should know, i've followed a few.
