All laws are based on morality. Christianity has always been recognized as part of America's common law.
Bravo Sierra. Prove it. It isn't in the Constitution. It is no where in Blackstones. It isn't in the USC anywhere.
The very idea of "common law", which should be called "english common law" (as it was adopted), predated christianity in england. It would be just as accurate to say "Paganism has always been recognised as part of America's common law". Our government and our legal system was based on reason.
Are you saying that "Love your neighbor" should be a law? Do I really need to be forced by government to love my neighbor, or just not do anything that interferes with his rights, without his consent? Are you going to confiscate ten percent of my earnings and give it to the church? When are the mass baptisms at the point of a gun scheduled?
You may say that Christianity is the part of America's common law, and you may find quotes of founding fathers to support that. Why, then, were some Christian rules made laws, while others weren't? Could it be that some rules, some morality, should not be forced, but are a personal decision?
While the literal definition of a theocracy may be a government beholden to the priests, if the rules of Christianity are the law, administered by whatever legal means, is their really a difference?
