As Glenn Beck gushed when he introduced David Barton to Beck's national audience on April 29, 2010,
"I brought David Barton in from WallBuilders because I really, truly believe that David Barton is he's a guy who I really think has been put in a in his place, in his position for a reason and, you know, David, everybody has a time and I have a feeling your time is coming... my gut tells me you are one of the most important men in America for this message today.
Introduction
David Barton, who recently has been tapped as an alleged "expert" on American history featured on the Glenn Beck show, has built a career upon his claim that United States government was founded on Biblical precepts. This creates a major problem - if America was founded as a Christian nation, how can we account for slavery ? Barton's articles on slavery on his Wallbuilders web site stress that many of the Founding Fathers were strongly opposed to the institution of slavery (which is true) but then he refers readers to a Wallbuilders article by Barton's close colleague Stephen McDowell, which explains that although Southern Slavery was wrong, it was wrong because it wasn't Biblical slavery as defined by Christian Reconstructionist theologian R.J. Rushdoony, whose basic approach was simple - what was permissible according to Biblical scripture is permissible now: including slavery.
McDowell's article cites R.J. Rushdoony's Institutes of Biblical Law six times in its footnotes and that's notable given that the book was Rushdoony's master work on how to implement Biblical law in the American legal system. R.J. Rushdoony's scheme included establishing stoning and burning at the stake for adultery, homosexuality, and idolatry, and the legalization of Biblical slavery. Leaders in the Christian Reconstructionism movement Rushdoony founded have for several decades now been trying to make it so.
Stephen K. McDowell appeared along with R.J. Rushdoony and other major Christian Reconstructionist leaders in a 1999 video titled God's Law And Society. You can watch some of those interviews (not McDowell's) on the Christian Reconstructionist web site The Forerunner. Here's The Forerunner editor Jay Rogers' description of the R.J. Rushdoony interview, in which Rushdoony calls for a "second American revolution" :
