When I first read the text in Coptic, it really took me aback. Its language is heated and polemical. Jesus is a Jesus who mocks everyone in the story. I didn't really like the text that much and didn't think it had much to add to our knowledge of Gnosticism and Christianity in the second century.
But as I have come to work on it so intensely, the text has come to change my mind. It is an extremely sophisticated text (and argument - yes there is an argument in it) and it is an extremely important early Gnostic text (and not for any of the reasons that scholars have published so far). I hope to finish my analysis this month.
