A more detailed Gnostic theology is as follows. The unknowable God was far too pure and perfect to have anything to do with the material universe which was considered evil. Therefore, God generated lesser divinities, or emenations. One of these emanations, Wisdom desired to know the unknowable God. Out of this erring desire the demiurge an evil god was formed and it was this evil god that created the universe. He along with archons kept the mortals in bondage in material matter and tried to prevent the pure spirit souls from ascending back to god after the death of the physical bodies. Since, according to the Gnostics, matter is evil, deliverance from material form was attainable only through special knowledge revealed by special Gnostic teachers. Christ was the divine redeemer who descended from the spiritual realm to reveal the knowledge necessary for this redemption. In conclusion, Gnosticism is dualistic. That is, it teaches there is a good and evil, spirit and matter, light and dark, etc. dualism in the universe.
