Sorry , I scanned through and forgot to see you said Constitution is “not” a prescription for how a man should live
Than what is the point of including the word God in the constitution if it has no prescription of how man should live?
The word "God" does not appear in the Constitution. Nor technically does that word appear in the DoI — the source of moral foundation of our country, of our nation: The Godhead is therein referred to as the Creator Who is Lawgiver of Nature as well....
Who is the Source and Ruler of the World, now and forevermore, Alpha to Omega....
Who knows His own all along the way....
The Framers of the Constitution to a man believed that the Constitution they crafted could only be enlivened, nurtured, and defended by men who were formed in the laws of God.
That is what makes the American historical "experience" so very "exceptional," even unique....
Again, the Constitution does not provide any particular prescription about how a man ought to conduct his life.
The Framers, however, again to a man thought the American citizen would (or at least ought to) get all his spiritual and moral ballast from his meditations of Holy Scripture. And as long as he did this, the Framers expected that there would be less for the secular courts of law to do. :^)
Nowadays, that hardly appears to be a testable proposition, so helplessly sunk we seem to be in "Lotus Land"....
"Lotus Land" is my shorthand for any constructor of a second reality who happens to live in first reality, which fact he has chosen to deny....
"Lotus Land" doesn't look particularly appealing to me, dear brother In Christ.
