FINE. What then, is SIN?
What do you think? What purpose is this stupid question for unless you are going to troll me about "following the law of Moses?" The only sins are those which trespass the law of Christ, not the law of Moses, of which we are free of totally.
We Christians are bound only to this: To love one another. All your Jewish laws and customs which you demand we follow, we are utterly free of.
