The single most disagreeable point was the suggestion most
of the founders were "probably Deists".Perhaps I am just not
schooled at such -but The claim seems cotrary to what I've
read of Franklin --and Jefferson.For their writings suggest
Deism as rare and unconventional as atheism. And M.E.Bradfords' work suggests most were active members of their local church.Then there is the centric problem of
confusing what is passed off as Deism today and confusing
the modern corruption of terms with what was understood as
Deism in the founding era 1730-1805.Most of the Founders were schooled in Calvanism.
It is interesting that you mention Franklin and Jefferson. I think the evidence on those two is overwhelming that they were deist (http://www.nobeliefs.com/jefferson.htm). However they both still were members of churches, and presumably attended them.
However many of the founding fathers were some denomination of christianity. I think it is amazing what the founders did. Our nation was the first civilization in the history of the world that, at least on paper, allowed anyone to worship how they wanted. The first time that the state was seperate from the church. Of course after the great revival in the early 1800s I think everything else lost favor especially deism.
Where the preamble declares, that coercion is a departure from the plan of the holy author of our religion, an amendment was proposed by inserting "Jesus Christ," so that it would read "A departure from the plan of Jesus Christ, the holy author of our religion;" the insertion was rejected by the great majority, in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and Mohammedan, the Hindoo and Infidel of every denomination.
