The ratification of the 1st Amendment completely precluded the Ten Commandments from being established as law.
Most diligent scholars of law can find every one of the commandments buried somewhere in the law codes adopted everywhere in Western societies, particularly in the United States and in every state of the Union.
Yeah, right. Lets start with the very first one:
"I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods before me."
Try enforcing that one. Good luck. You're going to need an awful lot of cattle cars to bring all us non-believers to internment camps for the ghastly crime of not honoring the religion of the State.
