Debunking Gnosticism
Fr. Theodore G. Stylianopoulos, in A Gospel In The Gospel Of Judas?:

In the cauldron of the current cultural war, it is no surprise that people would differ as radically as people did in the second century and still regard themselves as Christians. Some continue to teach that Jesus' transformed bodily resurrection is an unnecessary myth, despite the protestations of St. Paul (1 Corinthians, chapter 15). Others advocate same gender marriage despite the witness of the Scriptures, all of the historical wisdom and the drastic social implications. Still others have supported almost limitless destruction of the unborn as if only the will and convenience of the potential parent really counts. And many caught up in the spirit of the age, whether consciously or unconsciously, follow the post-modern message of looking for the real self, finding one's way, creating one's own truth, and doing one's own thing -- while still claiming to follow Christ. For such persons, the Gospel of Judas may perhaps be of considerable value. For many others, however, it is no gospel at all.
