>>If you look at it from that perspective, it is intensly funny.<<
For all the reasons you outline, I agree, it is a hoot. But from my perspective, it simply suggests just how abiding simony is. The way I read Jesus' going to the cross is as a demonstration of how expendible, ultimately, the body is. It must be sacrificed figuratively or literally as the case may be. The body is nothing. This, in turn, points to that which is MOST important -- that precious something that exists within the cup. This verse comes to mind:
"Behold, I have told you before, Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even to the west; so shall also the coming of the Son of man be. For wheresoever the carcase is, there will the eagles be gathered together" (Mt 24:25-28).
In my view, I doubt Jesus would have left anything to distract the faithful from the contents of the cup.
Just my two cents.
