Bock's second review
/As for my remarks in The Thirteenth Apostle, that Mark was written as pro-Pauline propaganda against the disciples in Jerusalem, Bock does not like or agree with this since he is of the opinion that early Christianity was much more harmonious than I see in our sources. Whatever one's opinion on the historical origin of Mark, the Gnostics who wrote the Gospel of Judas are interpreting it in just this sense: as polemic against the Twelve. Thus their characterization of the Twelve as ignorant and faithless, while Judas the confessor as a demon. All this is Markan interpretation on the part of the Gnostics.
