If the Gospel of Judas found in Codex Tchacos can be convincingly identified as being a Coptic translation of the original Greek Gospel of Judas that Bishop Ireneaus mentioned around A.D. 180 in his book, "Against Heresies," it will be an important step in the study of ancient gnosticism. We would have for the first time the chance to trace back the history of Sethian gnosticism to before the time of Irenaeus. This would be a significant gain in our knowledge of early Christianity.
