The Gospel of Judas
The latest entry in the "here's some new lost knowledge about who Jesus really is" is the soon to be published ... the Gospel of Judas.
Timed to take advantage of all of tDC marketing hype, there's an upcoming National Geographic special, which undoubtedly will be surrounded by inumerable stories rushing to proclaim shocking, a real revelation, the Jesus you never knew, blah blah blah blah.
At any rate, as with all of the GG (gnostic garbage) that's being recycled in tDC, this is all very old news as well. Jimmy Akin has a good overview here. Heck, St. Irenaeus (one of the Early Church Fathers) decimated the document in the second century!
Bottom line - The Gospel of Judas is a second-century forgery by a gnostic sect, who generally busied themselves trying hard to discredit anything related to the real, factual person of Jesus as recorded in the Gospels and faithfully proclaimed by Christians for the past 2000 years. Nothing new, nothing shocking, nothing true as claimed.
As with the rest of the GG, read enough about the Gospel of Judas to understand where it fits in, and how to simply show it's assertions are, at best, silly.
