Franklin cited the supreme authority of Scripture no less than a half dozen times in accepted literary form in his speech...For examples James 1:17(”Father of Lights’); Psalm 67:4(God governs all nations alluded to by God governs in the affairs of men)? ; Matthew 10:29...’two sparrows sold for a copper coin ? And not one fall to the ground,apart from your Fathers will—direct quote by Franklin -and this may be a line line taken from a sermon Dr.Franklin had heard.(For the idea that God can lift up or tear down a nation at will is a Biblical theme Job 36:22) Franklin cites Psalm127:1”except the Lord build the house they labor in vain that build it. (a direct quote) and alludes to Genesis 11:4-9 the story of the tower of Babel- this too seems to be from a popular sermon(Builders of Babel) That Dr.Franklin spoke to men who were active members of their church in the overwhelming majority.And many of them had graduated from Divinity school.All of those who had been educated in a colonial University had been educated in schools run by the State church -so it is no surprise that Dr.Franklin who was never far from his own religious upbringing in Calvinist tradition should cite Scripture.
IIRC, Franklin is regularly labeled a Deist at this forum. So now I know it is not true. He struck a chord at the Convention; they knew they would get nowhere without God's help.
