Early Christian mystical groups were called Gnostics, meaning those who know, because of their spiritual knowledge. Their teachers were persecuted and most documents destroyed because the Church desired a uniform set of beliefs to operate under. "Pistis Sophis" was the most important Gnostic work until the discovery and publication of "The Nag Hammadi Library". It remains an important milestone in Gnostic research and should be part of any serious study. It is the story of how we, as spiritual beings, have fallen into the physical world. The soul is asleep, unaware of its true nature, but the purpose of this gospel is to help awaken us.
