The Pistis Sophia is an extremely important Gnostic text, dating back to the early 2nd Century. The text claims that after His resurection, Christ remained on Earth for another eleven years, teaching His Disciples up to the first level of the Mystery. In Gnostic teachings, the Sophia is the female aspect of God, and Christ is the male aspect of Divinity. The title "Pistis Sophia" translates to the "faith of Sophia."
