Bart Ehrman

Dr. Ehrman is a Professor of Religious Studies at the University of North Carolina at Chapel Hill and has written a very popular book called

Misquoting Jesus : The Story Behind Who Changed the Bible and Why

Ehrman is a past evangelical turned agnostic.

I've run across Ehrman as I've been studying issues related to Dan Brown's Da Vinci Code. (Ehrman has also written a recent book critical of Da Vinci Code).

I plan to post more about the Da Vinci Code later, but I simply
wanted to link to recent comments by Ben Witherington and Dan Wallace on Ehrman's most recent book that can be found here.

For what it's worth, my own undergraduate degree was in Classical Greek and I also had the opportunity to study Textual Criticism under the late Harry Sturz and I found that learning about such matters strengthened rather than weakened my faith.
