It could be a passion story as co-written by Mick (Sympathy for the Devil) Jagger and The Matrix's mess-with-your-metaphysics Wachowski brothers: Judas Iscariot, vilified in the Gospels as Jesus' great betrayer, was not merely an Apostle--he was perhaps Christ's closest confidant. Technically speaking, he did drop a dime on Jesus. But there were extenuating circumstances, some having to do with the belief that the God of the Old Testament was not the ultimate God, that this world is not what it seems and ... well, for a full explanation, you'll just have to see the movie.
Er, rather, see the 31-page papyrus tractate. Provocatively titled The Gospel of Judas, the alleged Coptic Egyptian translation of a 2nd century manuscript promises to be a kind of Da Vinci Code--style everything-you-know-is-wrong thrill ride. According to its holders, the text will be unveiled this spring for the first time in at least 1,500 years. If your Coptic is rusty, there will be an official translation, and a National Geographic TV special in late April, they say. (Geographic declines comment.) You'll have eminent co-viewers: scholarly interest reaches up to the Vatican.
Personally, while I can understand the scholarly interest, I see no reason for concern here. First, its validity has not been firmly established. Second, even if it is what some claim it to be, it is a "gospel" of a heretical gnostic sect. Gnosticism in early Christianity is nothing new, so I do not see any dangers in learning more about what this errant group believed. They do not speak for the historic and orthodox Christian faith. They are simply another example of those who twist the truth to justify their sinful rebellion against God. There is no good news (gospel) according to Judas.
