Hello all,
Perhaps someone else has alluded to this already or even posted a link, but in case not, here's a link to a radio show in various formats (RealAudio, mp3, podcast):
Deciphering the Da Vinci Code.
Luke Timothy Johnson, a former Benedictine monk and priest, now married with seven children, and whom has
written negatively on Catholic teaching about marriage, artificial birth control, celibacy of religious, and divorce, does, in this radio program, a surprisingly good job in my opinion, in replying to questions on the formation of the canon of scripture and on gnostic texts.
