No, you missed the point of that excerpt- that such arguments are not “new”, and that it echoes the same opinion John Adams, Jefferson, among others, held:
“... the Common Law existed while the Anglo-Saxons were yet pagans, at a time when they had never yet heard the name of Christ pronounced or knew that such a character existed.”
— Thomas Jefferson, letter to Major John Cartwright, June 5, 1824 (see Positive Atheism’s Historical section)
“Christianity neither is, nor ever was, a part of the Common Law.”
— Thomas Jefferson, letter to Dr. Thomas Cooper, February 10, 1814, responding to the claim that Christianity was part of the Common Law of England, as the United States Constitution defaults to the Common Law regarding matters that it does not address.
I could say it was illuminating, just to be polite.
But it really wasn't.
For you evidently uncritically prefer the testimony of "experts" (in context or out of context) rather than actually having to perform your own personal analysis/critique of the ideas they advance.
I can love a Thomas Jefferson — but only up to a point. Whatever he said in public, or ultimately thought of himself, he is no god to me.
Could such a statement make any sense to you at all?
