That’s because even during extremely religious times the men were smart enough to bar fanaticism from a new free world.
It has often been seen on the Internet that to find God in the Constitution, all one has to do is read it, and see how often the Framers used the words “God,” or “Creator,” “Jesus,” or “Lord.” None of these words ever appears in the Constitution, neither the original nor in any of the Amendments. This lack of any these words does not mean that the Framers were not spiritual people, any more than the use of the word Lord means that they were. What this lack of these words is expositive of is not a love for or disdain for religion, but the feeling that the new government should not involve itself in matters of religion. In fact, the original Constitution bars any religious test to hold any federal office in the United States.
