Gospel of Judas
The Gospel of Judas is a Gnostic gospel. It was discovered in an antiquities market and published in October 2006 by the National Geographic Society. It is not a part of any canonical scripture and was written well into the third century AD well after the New Testament Gospels.
Like many Gnostic works, the Gospel of Judas claims to be a "secret account of the revelation that Jesus spoke in conversation with Judas Iscariot." The book is structurally different than the narrative accounts in the other gospels, as it is a series of dialogues or sayings of people. Thematically, the Gospel of Judas has Jesus proclaim Judas to be first among his disciples, and has Jesus instruct Judas to "betray" Jesus to the Romans in order for Jesus to fulfill his destiny of being crucified.
Most Gnostic teaching involved special "Gnosis" or a deep special knowledge that is not apparent to the unenlightened. This is contrary to the core and very simple message of Jesus preached in the other gospels and New Testament that people need a faith in Jesus Christ alone.
