Scot McKnight begins a three-part series on the problems of Ehrman & Pagels and their approach toward orthodoxy. McKnight calls it "The Gospel of Niggle". Here's the intro on his post:

I gave this paper sometime ago, but it pertains to The DaVinci Code movie. What I do is deal witih the proposals of heresy and orthodoxy behind the book, and the two major proponents of these theories today: Elaine Pagels and Bart Ehrman. It is a bit hard-hitting at times, but I think it is warranted. I’ll do this over three days. I thought I had posted this before, but didn’t find it.
