CainitesThe Cainites or Cainians (Καϊνοί, Kainoi, and Καϊανοί, Kaianoi) were a Gnostic and antinomian sect known to venerate Cain as the first victim of the Demiurge, the deity of the Old Testament, who was identified by many groups of Gnostics as evil. The sect was relatively small. They were mentioned by Tertullian and Irenaeus as existing in the eastern Roman Empire during the 2nd century. One of their purported religious texts was the Gospel of Judas. The oldest source is to be found in Irenaeus, Against Heresies.
SamaelSamael (סַמָּאֵל, Sammāʾēl, "Venom/Poison of God"; سمسمائيل, Samsama'il or سمائل, Samail; alternatively Smal, Smil, Samil, or Samiel) is an archangel in Talmudic and post-Talmudic lore; a figure who is the accuser or adversary (Satan as mentioned in the Book of Job), seducer, and destroyer (Mashhit as mentioned in the Book of Exodus). Although many of his functions resemble the Christian notion of Satan, to the point of being sometimes identified as a fallen angel, he is not necessarily evil, since his functions are also regarded as resulting in good, such as destroying sinners.
PtahilIn Mandaeism, Ptahil () also known as Ptahil-Uthra (uthra = angel or guardian), is the Fourth Life, the third of three emanations from the First Life, Hayyi Rabbi, after Yushamin and Abatur. Ptahil-Uthra alone does not constitute the demiurge but only fills that role since he is viewed as the creator of the material world in the Ginza Rabba, often holding an inherently malicious character. Matthias Norberg believed the name Ptahil to be composed of Aramaic פתאה and עיל, therefore meaning "God opened", although the verb can also mean "create" in Mandaic, but not in other Aramaic languages.
Tree of the knowledge of good and evilIn Judaism and Christianity, the tree of the knowledge of good and evil (ʿêṣ had-daʿaṯ ṭōḇ wā-rāʿ, ʕesʕ hadaʕaθ tʕov wɔrɔʕ) is one of two specific trees in the story of the Garden of Eden in Genesis 2–3, along with the tree of life. Alternatively, some scholars have argued that the tree of the knowledge of good and evil is just another name for the tree of life. Genesis 2 narrates that God places the man, Adam, in a garden with trees of whose fruits he may eat, but forbids him to eat from "the tree of the knowledge of good and evil.
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.
NoreaNorea is a figure in Gnostic cosmology. She plays a prominent role in two surviving texts from the Nag Hammadi library. In Hypostasis of the Archons, she is the daughter of Adam and Eve and sister of Seth. She sets fire to Noah's Ark and receives a divine revelation from the Luminary Eleleth. In Thought of Norea, she "extends into prehistory" as "she assumes the features here of the fallen Sophia." In Mandean literature, she is instead identified as the wife of either Noah or Shem. She is also sometimes said to be the syzygy of Adam.
Cain and AbelIn the biblical Book of Genesis, Cain and Abel are the first two sons of Adam and Eve. Cain, the firstborn, was a farmer, and his brother Abel was a shepherd. The brothers made sacrifices to God, but God favored Abel's sacrifice instead of Cain's. Cain then murdered Abel, whereupon God punished Cain by condemning him to a life of wandering. Genesis 4:3-16. Cain then dwelt in the land of Nod (נוֹד), where he built a city and fathered the line of descendants beginning with Enoch.
