A Valentinian Exposition is the second tractate from Codex XI of the Nag Hammadi Library.[1] Less than half of the text has been preserved.[2] The text explores the relationship between God, the created world, and humanity. It states that the material world is a shadow of the spiritual world and that humanity is a mixture of spiritual and carnal elements. The Demiurge, a lower deity, is responsible for creating the physical world and humanity, and the Devil, who is one of the divine beings, expelled his root from the body of humanity and caused the world to fall into sin. It also explores themes such as salvation through knowledge and understanding of one's true identity.
