While the U.S. Constitution is simply a document, the principles that have gone into that document are important. But, if we are not a godly people, and we are vicious and filled with debauchery, we are simply not capable of enjoying the liberties the Constitution offers.
Only a virtuous people are capable of freedom. As nations become corrupt and vicious, they have more need of masters -- Benjamin Franklin
Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other -- John Adams
