Abraxas is a word of mystic meaning in the system of the Gnostic Basilides, being there applied to the "Great Archon", the princeps of the 365 spheres. The word is found in Gnostic texts such as the Holy Book of the Great Invisible Spirit, and also appears in the Greek Magical Papyri. It was engraved on certain antique gemstones, called on that account Abraxas stones, which were used as amulets or charms. As the initial spelling on stones was Abrasax (Αβρασαξ), the spelling of Abraxas seen today probably originates in the confusion made between the Greek letters sigma (Σ) and xi (Ξ) in the Latin transliteration.
In the Platonic, Neopythagorean, Middle Platonic, and Neoplatonic schools of philosophy, the demiurge 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. Depending on the system, they may be considered either uncreated and eternal or the product of some other entity.
Gnosticism is a collection of religious ideas and systems which coalesced in the late 1st century AD among Jewish and early Christian sects. These various groups emphasised personal spiritual knowledge (gnosis) above the orthodox teachings, traditions, and authority of religious institutions. Viewing material existence as flawed or evil, Gnostic cosmogony generally presents a distinction between a supreme, hidden God and a malevolent lesser divinity who is responsible for creating the material universe. Gnostics considered the principal element of salvation to be direct knowledge of the supreme divinity in the form of mystical or esoteric insight. Many Gnostic texts deal not in concepts of sin and repentance, but with illusion and enlightenment.
The concept of an Ogdoad appears in Gnostic systems of the early Christian era, and was further developed by the theologian Valentinus.
Leviathan is a sea serpent noted in theology and mythology. It is referenced in several books of the Hebrew Bible, including Psalms, the Book of Job, the Book of Isaiah, the Book of Amos, and, according to some translations, in the Book of Jonah; it is also mentioned in the Book of Enoch. The Leviathan is often an embodiment of chaos and threatening to eat the damned after life. In the end, it is annihilated. Christian theologians identified Leviathan with the demon of the deadly sin envy. According to Ophite diagrams, the Leviathan encapsulates the space of the material world.
Samael is an archangel in Talmudic and post-Talmudic lore; a figure who is the accuser (Satan), seducer, and destroyer (Mashhit).
The Ophites, also called Ophians, were a Christian Gnostic sect depicted by Hippolytus of Rome (170–235) in a lost work, the Syntagma ("arrangement").
Celsus was a 2nd-century Greek philosopher and opponent of early Christianity. His literary work, The True Word, survives exclusively in quotations from it in Contra Celsum, a refutation written in 248 by Origen of Alexandria. The True Word is the earliest known comprehensive criticism of Christianity. It was written between about 175 and 177, shortly after the death of Justin Martyr, and was probably a response to his work.
The 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.
Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind". Genesis 1 tells of God's creation of the world and its creatures, including adam, meaning humankind; in Genesis 2 God forms "Adam", this time meaning a single male human, out of "the dust of the ground", places him in the Garden of Eden, and forms a woman as his helpmate; in Genesis 3 Adam and the woman eat the fruit of the tree of knowledge and God condemns Adam to labour on the earth for his food and to return to it on his death; Genesis 4 deals with the birth of Adam's sons, and Genesis 5 lists his descendants from Seth to Noah.
The Naassenes were a Christian Gnostic sect known only through the writings of Hippolytus of Rome.
The seven rays is a concept that has appeared in several religions and esoteric philosophies in both Western culture and in India since at least the sixth century BCE. They are also known as chohans or angels from heaven.
Against Celsus, preserved entirely in Greek, is a major apologetics work by the Church Father Origen of Alexandria, written in around 248 AD, countering the writings of Celsus, a pagan philosopher and controversialist who had written a scathing attack on Christianity in his treatise The TrueWord. Among a variety of other charges, Celsus had denounced many Christian doctrines as irrational and criticized Christians themselves as uneducated, deluded, unpatriotic, close-minded towards reason, and too accepting of sinners. He had accused Jesus of performing his miracles using black magic rather than actual divine powers and of plagiarizing his teachings from Plato. Celsus had warned that Christianity itself was drawing people away from traditional religion and claimed that its growth would lead to a collapse of traditional, conservative values.
Gnosticism used a number of religious texts that are preserved, in part or whole, in ancient manuscripts, or lost but mentioned critically in Patristic writings.
Gilyonim, or avon gilyon, are terms used by the Mishnah and Talmud to refer to certain heretical works.
The Perates or Peratae were a Gnostic sect from the 2nd century AD. The Philosophumena of Hippolytus is our only real source of information on their origin and beliefs. The founders of the school were a certain Euphrates and Celbes, elsewhere called Acembes and Ademes.
Sophia is a major theme, along with Knowledge, among many of the early Christian knowledge-theologies grouped by the heresiologist Irenaeus as gnostikoi (γνωστικοί), ‘knowing’ or ‘men that claimed to have deeper wisdom’. Gnosticism is a 17th-century term expanding the definition of Irenaeus' groups to include other syncretic and mystery religions.
Archons are, in Gnosticism and religions closely related to it, the builders of the physical universe. Among the Archontics, Ophites, Sethians and in the writings of Nag Hammadi library, the archons are rulers, each related to one of seven planets; they prevent souls from leaving the material realm. The political connotation of their name reflects rejection of the governmental system, as flawed without chance of true salvation. In Manichaeism, the archons are the rulers of a realm within the 'Kingdom of Darkness', who together make up the Prince of Darkness. In The Reality of the Rulers, the physical appearance of Archons is described as hermaphroditic, with their faces being those of beasts.
Justin or Justinus was an early Gnostic Christian from the 2nd century AD recorded by Hippolytus. He is often confused in sources with Justin Martyr as "Justin the Gnostic".
In some Gnostic writings, Sabaoth is one of the sons of Ialdabaoth. According to Hypostasis of the Archons and On the Origin of the World, Sabaoth dethrones his father Ialdabaoth. In both accounts, Sabaoth repents, when he hears the voice of Sophia, condemns his father and his mother (matter) and afterthat is enthroned by Sophia in the seventh heaven. Some Church Father report on the other hand, that Gnostics identified Sabaoth with Ialdaboath himself.
