Rather than comment at length on the recent furor over the "Gospel of Judas," I thought I would provide two links that I found helpful: by Mark Roberts and Ben Witherington.
When the Da Vinci Code craze hit a few years ago, something puzzled me that puzzles me still today: Why are so many so eager to read books from works entitled The Other Bible or extra-canonical gospels (such as The Gospel of Mary Magadalene), rather than dwelling deeply, passionately and patiently with the canonical gospels? There is enough in the Gospel of John to occupy even the most brilliant mind for a lifetime.
