While the U.S.A. was founded by Christians, today the U.S.A. is a pluralistic society. At the theological level we are talking about eternity and final authority. At the political level we are talking about time and temporal authority. KJV Mark 12:17 And Jesus answering said unto them, Render to Caesar the things that are Caesar's, and to God the things that are God's. And they marvelled at him.
