Yo - dipwad, James Madison authored the Constitution. And FYI, Thomas Jefferson authored the Declaration of Independence (where God is referenced).
And jacka$$, explain this if 'God' is NOT in the Constitution:
Now if not God, exactly whom were 'we' asking to secure "blessings", huh?!? The frigging King of Siam?!?Preamble We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America.
