Why don't modern Christians follow the OT? I believe the standard answer is that Jesus came to reinterpret it, so they should only follow the NT, and the parts of the OT which the NT validates. But why would God give a commandment and subsequently withdraw it?
For example, Deuteronomy 22:21 says what should be done if a woman was not a virgin at the time of her marriage.
>"Then they shall bring out the damsel to the door of her father's house, and the men of her city shall stone her with stones that she die: because she hath wrought folly in Israel, to play the whore in her father's house: so shalt thou put evil away from among you."
According to Catholic dogma, the Bible was inspired by God, so why would he set down these rules if Jesus would come along and revise them? Is God not infinite through time? If his rules change, then either God changes (he doesn't), or morality is arbitrary and has no significance outside of God's command, illustrated in Genesis 22. God tells Abraham to sacrifice his son, and God’s command is good and just, so Abraham prepares to kill his son.
Is God just some sick fuck sitting up there bending us to his will, reminding us that if we don’t follow his commands to the letter then we’ll get buttfucked by Satan’s spiny phallus and filled with his searing hot loads for all eternity? What is God’s point in telling the Jews one thing, then coming to earth and saying another?
