evidence: Finally, and perhaps most notoriously, is the spurious Henry quotation that "it cannot be emphasized too strongly or too often that this great nation was founded, not by religionists, but by Christians; not on religions, but on the gospel of Jesus Christ!" Again, this is a perplexing case because Henry certainly was a devout Christian, but the quotation itself is of relatively recent origin. The quotation apparently came from a magazine commentary on Henry's faith in 1956, which later writers took as a quotation from Henry himself. Popular Christian historian David Barton once regularly used this statement in his writings and speeches, but he came under such fierce criticism that he retracted it (and others) as an "unconfirmed" source. The quotation still appears regularly in Facebook and Twitter posts, and, remarkably, in presidential aspirant Newt Gingrich's 2011 book A Nation Like No Other (p. 76). And this from the only candidate with a history Ph.D.!
