The founding fathers were religious men, but that was not their
philosophy. Being men of education during their time, they were well
read and took their philosophy from the idea of Natural Law. They
believe as stated in the Declaration of Independence, that all men were
created equal and that their Creator (who they called God) had given all
men certain rights which could not justly be taken away.
This
manifest itself in their view of use of government being to serve the
people and the view that government must not interfere with the rights
God had given. Hope this helps!!
