Bart D. Ehrman

He's the Bowman and Gordon Gray professor of religious studies at the University of North Carolina, Chapel Hill. His new book, Lost Christianities: The Battle for Scripture and the Faiths We Never Knew, chronicles the second and third centuries before Christianity as we know it came to be. Ehrman has also edited a collection of the early non-canonical texts from the first centuries after Christ called Lost Scriptures: Books That Did Not Make it Into The New Testament.
