April DeConick has recently finished a book on the Gospel of Judas called The Thirteenth Apostle: What the Gospel of Judas Really Says. In a recent post, Bibliography for the Gospel of Judas (in English), DeConick lists the several studies that have already appeared on Judas, or that are currently in print. A commenter adds another, and I can add one more:
Simon Gathercole, The Gospel of Judas: Rewriting Early Christianity (Oxford: OUP, Estimated publication date November 2007)
I have read the book in manuscript and am happy to say that is outstanding.
