A Sethian Gnostic apocalypse written in the name of Melchizedek, “Priest of God Most High” (see Gen. 14:18). Its title occurs at the beginning. Codex IX is quite fragmentary; much of the text is lost in lacunae. The text reflects influence from early Jewish lore concerning Melchizedek, but also features Christ, with whom Melchizedek is ultimately identified. It also includes cultic invocations of various of Sethian Gnostic mythology. Extant only in Coptic, Melchizedek was originally composed in Greek, probably in third-century Egypt.
