I thought this was an interesting observation by someone who is clearly not pleased by the growth of Calvinism in fundamentalist circles. The "reporter" pins this phenomenon on Christian books (especially books by Piper and MacArthur) and noted the role of the BJU bookstore in this.
I have to admit that I was pleasantly surprised to visit my alma mater's bookstore a couple of years ago and to find all the Puritan works that they carry; they even carry Dabney books (although they still don't stock my biography of Dabney, for reasons that I've yet to figure). When I was a student (1990-3), we had to go to Crossway Bookstore (not to be confused with Crossway Publishers) across the street to find Puritan and Banner of Truth books; now, Crossway doesn't carry those materials any more (I last visited there this past summer).
It was reading books when I was a student at BJU that moved me into the Calvinist (and eventually Presbyterian) camp: Jonathan Edwards, B. B. Warfield, Lorainne Boettner, Charles Hodge, Louis Berkhof, Jay Adams. But it was also reading the Bible and compare what God's Word said with what these older writers said. It was hard to give an Arminian reading to John 6 or Ephesians 1 or Romans 9--and once my paradigm couldn't account for those texts, I willingly became a Calvinist.
One thing for which I've always been grateful is that my alma mater taught me to take the Bible with absolute seriousness and to follow God's truth wherever it would lead. It was the University's position on biblical authority that gave me the freedom to listen to what the Bible taught on God's rights as King in all of our lives, especially in salvation. And perhaps that is why, even more than the good Christian literature being circulated, that many fundamentalist youths are becoming Calvinists.
