I was reading some Gnostic scriptures myself. It is amazing all of the writings that are excluded from the bible. The portion I read really elevated women, and particularly, Mary Magdelene. They even talked about the jealously the men of the day felt toward her for having an honored position. The scriptures chosen for inclusion reflect this. Magdelene is forever a whore.
It's a book of man. Even if it specifically says atheists are going to hell, it is no more authoritative than an Archie Comic.
