Also, and could be wrong, but I thought both are mentioned in the Bible.
Its not contained in the Bible
Of course its contained in the Bible:
Rom 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Rom 5:13 (For until the law sin was in the world: but sin is not imputed when there is no law.
Rom 5:14 Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come.
Also it permeates the life and teachings of Christ,its all throughout the Old testament also. But any further elaboration to people who clearly have their minds already made up would be useless. I have a feeling that I could show a hundred Biblical references which clearly illustrate the point but it would simply waste my time.
