He gave Beck the historical-religious justification to say whatever he wanted to say.
That’s pretty much what I figured.
Barton likes to take the Christian roots of American order and exaggerate them wildly beyond what the facts support.
He misleads people by telling them what they’d like to believe and Beck is the perfect foil, and maybe a willing one, for Barton. I’m never sure whether or not Barton actually believes what he writes- although I suppose he does.
In contrast there is Bernard Bailyn’s excellent “The Ideological Origins of the American Revolution” which includes the Christian influence on America’s founding without the excesses of Barton.
