I highly recommend James Hutson’s book of quotations, The Founders on Religion.
Reading it I realized (or rather, was reminded) that, of the six most influential founders of the US (John Adams, Benjamin Franklin, Patrick Henry, Thomas Jefferson, James Madison, and George Washington), two were Unitarians (Adams and Jefferson), and one was a deist (James Madison), one was an all-out nonbeliever / non churchgoer (Franklin).
That leaves only two of the six as remotely resembling the historic Christian faith. (Note: of these six, four were Episcopalian!)
Is it any wonder that the landscape of American Christianity (to say nothing of the Episcopal Church!) today is so muddled? The more things change….
