The Bible told man not to Murder long before the state told man not to Murder... so is that the Church ruling the state or man ruling based in ideals learned from God and in Church?

Religion was mankind's first crack at philosophy, so you're probably never going to untangle religion from morality.

But which laws should be codified into civic law? The Bible tells me I have to get circumcised too. Should the state mandate that?

That's what elections are about, whose morality is codified in law. Separating morality or the religious beliefs/non-beliefs of any legislator from the laws they promote is mythological nonsense.
