Now I am Jewish and prefer the Oral and Written Law [the Old Testament and the Talmud] as a working system.

I should mention that a lot of the  work that goes into the Talmud is because we assume the Law of God is meant to be obeyed and that it is self consistent. So ironing out the difficulties is important--it is not just an intellectual exercise but it comes from the fact that we Jews are interested in obeying the word of God.

So what I have suggested is an idea based on Hobbes. You a  government that is allotted only certain powers [as the US Constitution was originally conceived] and within that context there is a voluntary  area of people that accept on themselves to keep the Law of God.]
