Gotta be deliberate ignorance. I think he was just using a phrase he heard somewhere without knowing or caring about its historical/theological context. Remember, this is a guy who also claims to be an admirer of Ayn Rand, even though nearly everything about his political philosophy is exactly the opposite of Rand’s, except the rapacious selfism.

Like a lot of right wing ideologues, his real knowledge of the subjects about which he spouts off is about a micron deep.
