Does the "Gospel of Judas" Discredit Historical Christianity?

The media has created a firestorm of hype surrounding the recent publication of The Gospel of Judas. Albert Mohler addresses this issue in his article, "From Traitor to Hero? Responding to 'The Gospel of Judas. He writes:

In sum, the publication of this document, dismissed as heretical by the early church, offers great insights into the character of Gnostic heresies the early Christians had to confront and correct. But this text poses no threat to the authority of the Bible or to the Christian Gospel. It was identified and dismissed as heretical by the early church for one simple reason -- it was, and is.

He further discusses it on Thursday's edition of his show The Albert Mohler Program.
