'Gospel of Judas' Tells His Side.
I've heard this type of discussion before, and had seen mention of it recently, but I just happened to actually read the article that described it.
For an in-depth look at the gospel, please read the "Gospel of Judas" article on Wikipedia.
For background on what is meant by "Coptic" in the article, please see the Coptic Christianity article on Wikipedia.
For more related information, see the article "The Lost Gospels" on the National Geographic website which covers this along with several other related works.
