Even the four that are recognized as Deists, used scripture in their personal writings which is well documented.  The only reason they are they are even considered Deists is due to the fact those 4 did not belong or declare a specific religious church.  But all them were well educated in scripture.

Thomas Jefferson later in life was part of a Baptist Bible study group and taught calvanist theology.

Benjamin Franklin called the Continental Congress to pray, which makes the claim that he was a deist rather questionable.
