I have my problems with Bill Barr but this isn’t one of them:

During his segment on Saturday, Barr told the audience about what he believed was a threat to the entire western world: the U.S. public school system — which seeks to control how children are raised while creating a hostile environment for traditional religion, The Federalist reported.

The former attorney general has argued that for years, America’s unique self-government system cannot exist without traditional religion — an argument that closely aligns with the words of the second U.S. President John Adams: “Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.”
Indeed so. As I said myself, just a year ago:

Every culture in history has a religion atits philosophical root.. The most successful cultures in history have had the today of Christian ethic as their philosophical root. America could not have been created with Islam, atheism, or any of the pantheistic religions as their root. Again, the degree to which we have gotten into problems is directly linked to our abandonment of that premise.
