jmp brings up an interesting subject here. The problem is that you need to back up first and decide what is our role as a Christian citizen in a govt. that is wholly secular. I suggest, as a starting point, that you read the article titled "Christian Politics according to Abraham Kuyper" at this url: http://www.ucalgary.ca/%7enurelweb/papers/irving/kuyperp.html

By the way, I agree with Pilgrim that Theonomy is a perversion.
