That seems like a speculative topic — to try and guess what our first president under the Constitution would have to say to modern Americans.
But actually I won’t speculate at all. I’ll use some of his own writings to make my points (or his points). And they won’t be from some of his obscure writings, gleaned from arcane, private letters the way the Supreme Court did in a 1947 decision with a private letter Thomas Jefferson wrote to the Danbury Baptists. That decision changed forever the way religion, specifically Christianity, is treated in the public square — and not for the better.
