ZostrianosZostrianos is a Sethian Gnostic text. It is the first tractate of two in Codex VIII of the Nag Hammadi library. It takes up 132 of the 140 pages in the codex, making Zostrianos the longest tractate of the entire library. However the text is extensively damaged, especially in the center, making the document difficult to fully understand. The Coptic manuscript is a translation of a Greek original, likely written in Alexandria in c. 200 AD. In the text, Zostrianos goes on a heavenly journey and receives divine knowledge from the aeons.
SethianismThe Sethians were one of the main currents of Gnosticism during the 2nd and 3rd century CE, along with Valentinianism and Basilideanism. According to John D. Turner, it originated in the 2nd century CE as a fusion of two distinct Hellenistic Judaic philosophies and was influenced by Christianity and Middle Platonism. However, the exact origin of Sethianism is not properly understood. The Sethians (Latin Sethoitae) are first mentioned, alongside the Ophites, in the 2nd century, by Irenaeus (who was antagonistic towards gnosticism) and in Pseudo-Tertullian (Ch.
Nag Hammadi libraryThe Nag Hammadi library (also known as the "Chenoboskion Manuscripts" and the "Gnostic Gospels") is a collection of early Christian and Gnostic texts discovered near the Upper Egyptian town of Nag Hammadi in 1945. Thirteen leather-bound papyrus codices buried in a sealed jar were found by a local farmer named Muhammed al-Samman. The writings in these codices comprise 52 mostly Gnostic treatises, but they also include three works belonging to the Corpus Hermeticum and a partial translation/alteration of Plato's Republic.
New Testament apocryphaThe New Testament apocrypha (singular apocryphon) are a number of writings by early Christians that give accounts of Jesus and his teachings, the nature of God, or the teachings of his apostles and of their lives. Some of these writings were cited as scripture by early Christians, but since the fifth century a widespread consensus has emerged limiting the New Testament to the 27 books of the modern canon. Roman Catholic, Eastern Orthodox, and Protestant churches generally do not view the New Testament apocrypha as part of the Bible.
