But acknowledging a very generic God as the official benefactor and law giver of the USA is both explicit and implicit in the founding documents of the USA.No one has yet pointed out where the Constitution states or implies it. It would have been the simplest thing to place this acknowledgement (or even a reference to the Declaration) in the Preamble, and it was not done. Not even as "the heavens", or "providence", or any of the other words Washington used apparently to avoid mentioning God or Jesus.
Considering the precision of the Framers and the known support for Separation among Madison, Jefferson, Franklin, and others, it makes a great deal of sense to presume that the omission was quite intentional.
