It is the buckle of the Bible Belt !
I’d always heard that Bob Jones University was the buckle on the Bible Belt.
BTW....the original Bob Jones, and several of his progeny did and do hue the strict Baptist, anti-charismatic line. But a while back I heard that one of the Joneses in the line of succession had jumped the tracks and was a stalwart charismatic. Anyone know anything about that?
