To a cheering crowd, Terry shouted that ours is a “Christian nation,” that “we don't worship Buddha, we don't worship Mohammad, we don't worship Allah,” and that anyone who doesn’t like “the way we do things” should “get out.”
... But he went further when he said that we–“Americans,” presumably–are Christians who worship “one God, and his name is Jesus Christ.” ...
I won't touch the Rev.'s personal theology. It certainly is a central tenet of Christianity that there is one God and that Jesus is God. But it's precisely NOT what the American Founding was all about. The key Founders believed all monotheists, including Muslims, worshipped the same God.
And here is John Adams on the notion that Jesus is God:
"An incarnate God!!! An eternal, self-existent, omnipresent omniscient Author of this stupendous Universe, suffering on a Cross!!! My Soul starts with horror, at the Idea, and it has stupified the Christian World. It has been the Source of almost all of the Corruptions of Christianity."
-- John Adams to John Quincy Adams, March 28, 1816.
