Authoritative Discourse, also known as Authoritative Teaching or Authentikos Logos[1] (Sahidic Coptic: ⲁⲩⲑⲉⲛⲧⲓⲕⲟⲥ ⲗⲟⲅⲟⲥ)[2] is a text about the journey of the soul.[3] It is the third of eight treatises in Codex VI of the Nag Hammadi library texts, taking up pages 22–35 of the codex's 78 pages.[4] The text uses metaphors extensively to describe the origin, condition, and ultimate destiny of the soul,[5] calling the soul a prostitute, a seed of wheat, a contestant, an invalid, a fish, and a bride.[6] Researchers have debated whether the text should be classified as Gnostic, Christian, or both.[7]
