The Epistle of Eugnostos or Eugnostos the Blessed is a Gnostic epistle found in Codices III and V of the Nag Hammadi library. Both copies seem to be a Coptic translation of a Greek original that was composed in Egypt around the late 1st century; the copy from Codex III is the earlier translation. Scholars note that the text is interrelated with The Sophia of Jesus Christ; SJC adds more specifically Christian elements to the cosmology-focused Eug. The text is a philosophical discourse on the nature of God and the world. The author asserts that previous human inquiries have failed to reach the truth about the nature of God, who is ineffable and beyond human understanding. The author describes a belief system in which there is an Immortal Man who reveals various aeons and powers with different names and authorities over different kingdoms and worlds.
