“While this document will tell us more about the split off movement called Gnosticism, and so is of considerable interest as we learn more about church history in the period from the late 2nd century through the fourth century, it tells us nothing about the origins of Christianity or the beginnings of the Jesus movement.
“. . . this document has no material which could or should shake the faith of Christians in what is said in the NT about Jesus and Judas for the very good reason that it comes from a much later source, and one that not even its advocates are really suggesting is written by the historical Judas. In fact it is just another example of the phenomenon known as pseudonymity— documents with falsely attributed authors— other such examples are the Gospel of Thomas, the Gospel of Peter, The Gospel of Mary, the Gospel of Philip and so on. . . .
“. . . watch the National Geographic Special with a critical eye, and the baloney detection meter fully operational.” (Ben Witherington)
