Tripartite Tractate

The Tripartite Tractate is a Valentinian Gnostic work. The date is estimated to the second half of the third century or the fourth century but is "most likely based on an earlier Greek version." It is the second-longest text in the Nag Hammadi library. It is the fifth tractate of the first codex, known as the Jung Codex. It is untitled, and instead it gets its name "from the fact that the ancient copyist divided the text with decorative markings in two places, thus separating the tractate into three parts." The first part describes the relationship between the Father, the Logos, the Church, and the aeons. The second part contains the Gnostic creation narrative, in which man is created by the Demiurge and is a mixture of both spiritual and material substances. The third part explains the Savior's role in salvation.
