Here's the editor of Chalcedon Reports in his own words., on a sympathetic web site.
For nearly a century and a half the National Reform Association has pressed for the crown rights of Jesus Christ in the political life of the nation. This implies a nation covenanted with God. One of the (though by no means the only) means of doing this is formal recognition of the authority of our Triune God and of Christianity in the prime political instrument(s) of the nation. Another means is requiring Christian test oaths for the civil magistrate and for all voters in a democracy.
Note the obvious and direct conflict with Article VI of the Constitution.
I suppose it's a matter of degrees.
Do you believe we should ditch "under God" from the Pledge of Allegiance?
