Christians love to claim that the Bible is an infallible source of morality. In this post I intend to demonstrate that the Bible (and, by extension, the deity who supposedly wrote it) is contradictory and imperfect, and therefore cannot be used as an infallible source of morality.
The Contradiction:
Consider the case of "the woman taken in adultery" vs the case of "the man who picked up sticks".In the latter instance the Hebrews find a man gathering sticks on a Saturday (the Sabbath). They're unsure if gathering sticks constitutes a violation of the Sabbath or not, so they take him to Moses and ask Moses to get Yhwh to clarify the law for them. Yhwh instructs the Hebrews to stone the man to death for breaking the Sabbath.
In the former instance, the Pharisees bring Jesus a woman who was caught in adultery, and remind him that the "law of Moses" tells them that the woman must be stoned to death. The Pharisees then ask Jesus what he says her punishment should be, to which Jesus responds "Let him who is without sin cast the first stone". Because Judeo-Christian morality holds that all have sinned, the woman is not stoned to death.
