Five SealsIn Sethian Gnostic texts, the Five Seals are typically described as a baptismal rite involving a series of five full immersions in holy running or "living water," symbolizing spiritual ascension to the divine realm. The Five Seals are frequently mentioned in various Sethian Gnostic texts from the Nag Hammadi library. While some scholars consider the Five Seals to be literary symbolism rather than an actual religious ritual, Birger A. Pearson believes that the Five Seals refer to an actual ritual in which the initiate was ritually immersed in water five times.
DemiurgeIn the Platonic, Neopythagorean, Middle Platonic, and Neoplatonic schools of philosophy, the demiurge (ˈdɛmi.ɜrdʒ) (sometimes spelled as demiurg) is an artisan-like figure responsible for fashioning and maintaining the physical universe. The Gnostics adopted the term demiurge. Although a fashioner, the demiurge is not necessarily the same as the creator figure in the monotheistic sense, because the demiurge itself and the material from which the demiurge fashions the universe are both considered consequences of something else.
Refutation of All HeresiesThe Refutation of All Heresies (Φιλοσοφούμενα ή κατὰ πασῶν αἱρέσεων ἔλεγχος; Refutatio Omnium Haeresium), also called the Elenchus or Philosophumena, is a compendious Christian polemical work of the early third century, whose attribution to Hippolytus of Rome or an unknown "Pseudo-Hippolytus" is disputed. It catalogues both pagan beliefs and 33 gnostic Christian systems deemed heretical by Hippolytus, making it a major source of information on contemporary opponents of Christian orthodoxy as understood today.
NaassenesThe Naassenes (Greek Naasseni, possibly from Hebrew נָחָשׁ naḥaš, snake) were a Christian Gnostic sect known only through the writings of Hippolytus of Rome. The Naassenes claimed to have been taught their doctrines by Mariamne, a disciple of James the Just. The retention of the Hebrew form shows that their beliefs may represent the earliest stages of Gnosticism. Hippolytus regards them as among the first to be called simply "Gnostics", alleging that they alone have sounded the depths of knowledge.
