Speculation.Many -if not most were active members -some were even leaders in their local church. M.E.Bradford documented the religious affiliation of many of the Founders Franklin was a Deist ,who was burried in a church
cemetary,and who declared he was "never far" from the teachings of the church .James Wilson was an Epsicopalian
that became a Desit. Hugh Williamson was a Presbyterian who may have become Deist--Only James McClung Seemed have
no record of Church membership.Unless they are here to question it is a fools dive to claim one knows if they were Deist of Christian. But Franklin said Deism was basically a novelty that didn't catch onin America any more than being an Atheist or an indfidel.
