All the founding fathers principles were based on the bible. If the Bible was good enough for them to base this government on then it's good enough for us to keep basing this government on.
We started getting in trouble (socially and culturally) when we strayed from biblically correct law.
If you want biblically correct laws I recommend you go live in a theocracy, like the Vatican City. The United States of America does not operate, and never has, according to the Mosaic Code.
