Yes but the founding fathers had no official state religion, even though much of the framework (though denied by the left) was based in Christianity.
Much of the spirit was, but the Founders were wise enough to refrain from tying the Constitution to the tenets of any one faith. Too bad we didn't insist that they do the same.
It is a shame, isn't it? The Constitution is one of the most brilliant documents ever written. Too bad the Iraqis didn't read it and learn from it.
