[little jeremiah]

Theocracry, in the definition you kindly provided, means more or less what I said - ruled BY religious authority. A government with laws founded on traditional moral absolutes is NOT a theocracy. In my Webster's theocracy means:
"government of a state by immediate divine guidance or by officials regarded as divinely guided." This agrees with the "in my own words" definition I provided above.

If someone posits that governments should rule (i.e. enact and enforce legislation, IOW laws) that have NOTHING to do with moral absolutes as handed down by spiritual or religious tradition, where do the concepts of right and wrong come from?

Answer: they must come from the minds of men. A funny thing about the minds of men; the only commonality is that will always disagree. So the final word about what should be legal, illegal (IOW right and wrong) is whoever has the power at the moment. So your version is this: MIGHT MAKES RIGHT.

Totalitarianism.
