Your response I think mixes up two issues. One pertains to the nature of law. Everyone lives by law (standards on moral right and wrong). The question in every civilization is whose law will a majority follow? Western civilization up until the last century agreed Biblical law was it. (English law stems from the first law code of King Alfred, which in turn begins with the 10 commandments.) Can you really say the atheistic law code has been a sucess given this century's implementation record of Nazi Germany and the Communist states of USSR and China?
The second issue is the relationship between church and state, or who determines the content of the law; who enforces it. The Reformation answered this question in a way which I think created the freest society in history (see REX LEX by Rutherford, written as a refutation of the divine right of kings) and its implementation in colonial America. I recommend to you NEVER BEFORE IN HISTORY by Amos. Also see the web page, "American Colonists Library" which traces the intellectual development of our Constitution.
Thanks, wjeanw, I'll take you up on the reading list. Never let it be said that my education stopped when I left school.
P.S. You eloquently put what I basically was trying to say, Thanks again.
