My House Did not have a Builder (or did it?)

[Astreja]

The blood has to be sinless in order to cover for sins, which is why the Messiah had to shed His blood and die on the cross.

Your alleged "Messiah" was far from sinless.  In the Gospels he does a great number of despicable things -- Verbally abused a foreign woman, talked back to his mother (clear violation of a commandment there), destroyed a farmer's herd of pigs, assassinated a fig tree, told his disciples to commit Grand Theft Ass and Colt so that he could ride into Jerusalem in style, and told an occasional lie (again, a commandment violation).

Just a narcissistic little brat whose ignominious death at the hands of the Romans was romanticized and mythologized by cultists.
