The problems are not limited to a single book.
Political philosopher Greg Forster, an expert on John Locke, decided to take a look at one of Barton’s essays on Locke and found it to be filled with errors.
As historian John Fea points out, it appears that virtually no Christian colleges—conservative or otherwise—teach or endorse Barton’s revisionist views, though he is still very popular in some conservative Christian circles (especially in some, though of course not all, homeschooling networks).
This is actually a very interesting test case for those who have bought in to Barton’s historiography, methodology, and conclusions. Do we care about the truth, or do the conclusions we want to hear justify the means used to obtain them?
