I was supposed to write more about this topic but it just occured to me that I may not be the right person to comment on this so I’ll just leave it to the experts. Here is an excerpt from Dr. Al Mohler’s (An Author, Speaker and President of the Southern Baptist Teological Seminary) article on The Gospel of Judas:
“What are Christians to make of all this? The publication of The Gospel of Judas is a matter of genuine interest. After all, it is important for Christians to understand the context of early Christianity–a context in which the church was required to exercise tremendous discernment in confronting heretical teachings and rejecting spurious texts.
The scholarly research behind the publication of The Gospel of Judas appears to be sound and responsible. The codex manuscript was submitted to the most rigorous historical process in terms of dating, chemical composition, and similar questions. In the end, it appears that the document is most likely authentic, in terms of its origin from within a heretical sect in the third century.
Nevertheless, extravagant claims about the theological significance of The Gospel of Judas are unwarranted, ridiculous, and driven by those who themselves call for a reformulation of Christianity.”
