Peter Enns a "leading postmodernist"

I'm not well up on the details of the controversy about Dr Peter Enns' doctrine of Scripture at Westminster Seminary though I understand Enns has repeatedly affirmed inerrancy. I was surprised to see that the Amazon blurb for Greg K. Beale's new book, The Erosion of Inerrancy in Evangelicalism: Responding to New Challenges to Biblical Authority (Crossway) describes Enns as "one leading postmodernist".
