"You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men." Matthew 5:13
Genesis 1:26,28 give us the general cultural mandate for God's people. We are God's vice-regents who are to exercise godly dominion over all creation.
"Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things I have commanded you; and lo, I am with you always, even to the end of the age." Matthew 28:19-20
Christ's Great Commission is not a bare suggestion to send out some missionaries and hope for a few baptisms - discipling nations means bringing whole people groups under the Lordship of King Jesus. That would seem to imply cultural transformation.
Our nation's laws will be in chaos so long as human despots are allowed to create 'law' by judicial fiat. Our laws must be tied to Biblical Law.

Keep in mind that Christ walked this earth at a time when it was considered perfectly normal for people to live under oppressive, totalitarian governments. And nothing He said ever indicated that this was somehow unacceptable.
Reverend, your exegetical principles are loose. "Discipling" means whatever the men did who heard the word. We must presume that the ecclesiology and practice of the book of Acts is an accurate illustration of what Jesus said, and is the sum total of the "cultural mandate" the church has the right to shoulder.
