There are so many others, that I just have to give a few "dishonourable mentions":
- for the "sheer pointlessness" category:
Christ dies for our sins. If we need to be forgiven, why doesn't God
just forgive us? What sense does it make to torture His Son to death? Who
made the silly rules here?
- for the "pettiness of God" category:
Job, hands down. God wants to impress the devil, and kills people to
do it.
- for the "just obeying orders" category:
Abraham demonstrates willingness to kill his own son because God said
to. I would say Abraham failed any test of basic morality by doing that,
but God supposedly approves of such murderousness.
- for the "most macabre" category:
the Last Supper, where Jesus says "this is my body you eat; this is
my blood you drink". To the extent that that is true, and in whatever way
it is true, it is CANNIBALISM. (Of course this derives from the old harvest
religions, where the grain was the body of the harvest god and the wine
was the blood of the god.)
- for the "most embarrassingly transparent cover story":
the virgin birth. Mary was a virgin. Right. Obviously the girl got
pregnant out of wedlock. It was commonplace in the ancient world to attribute
such "unexplained" events to the gods.
- for the "flat earth" category:
God makes the sun stand still so the Isrealites can win a battle. This
passage was much quoted as "proof" that the sun moved around the earth,
not vice versa. "To assert that the earth revolves around the sun is as
erroneous as to claim that Jesus was not born of a virgin." Cardinal Bellarmine
(1615, during the trial of Galileo)
- for the "throw your family to the wolves" category:
Lot offers his daughters to the rape minded mob.
- for the "God fears man" category:
the Tower of Babel.
- for the "most obvious fable" category:
the creation myth - make that myths. For the sequence in which things
were supposedly created, maybe this should get "most hilarious" too.
Runner-up: Noah and the Flood.
I am leaving out so many others; just too many candidates!
