Secular law is based on God's law. The question I was asking was if you eliminate God's law, what is secular law based on? And what it is based on today because of current public opinion can change tomorrow. What if islamic law wins out in the future? Does that make it okay to murder women who won't cover up properly? It's a slippery slope.
Listen, you're positing an opinion as a fact. Societies throughout time have had prohibitions against murder without ever having the benefit of receiving the "Word". To be honest, I'd rather know that someone doesn't kill their neighbor because they realize it is WRONG... because they have no right to deprive another of life...not because they're worried about what God will do.
When the laws given by God in all the religions of the world (which laws are essentially the same) are tossed in favor of laws invented by the minds of men, guess what happens.
I think you know.
Lots of different people have different ideas on what is wrong and what is right. Wildly different.
Here comes consensual cannibalism, "inter-generational" sex as promoted by NAMBLA, inter-species sex, infanticide, and on and on and on. Even Communism is a system of morality, of right and wrong, invented by the mind of man. And since there are always some recalcitrants who don't want to go along with what other people say is right and wrong, secular based morality always turns into tyranny, since the said recalcitrants need to be forced, for the good of all.
That's the best reason I can think of to keep the government neutral in terms of religion.
If you let it come down on the side of Christianity, it's only a matter of time before Muslims outnumber Christains somewhere and all of a sudden your tax dollars are going to make the Koran and daily prayers to Mecca a mandatory part of grade school.
The bottom line for me is that the government shouldn't take sides in matters of faith. Render unto Caesar and all that.
