Gnostic
Gnosticism (from Ancient Greek: , romanized: ''gnōstikós'', Koine Greek: �nostiˈkos 'having knowledge') is a collection of religious ideas and systems that coalesced in the late 1st century AD among early Christian sects. These diverse groups emphasized personal spiritual knowledge ('' gnosis'') above the proto-orthodox teachings, traditions, and authority of religious institutions. Generally, in Gnosticism, the Monad is the supreme God who emanates divine beings; one, Sophia, creates the flawed demiurge who makes the material world, trapping souls until they regain divine knowledge. Consequently, Gnostics considered material existence flawed or evil, and held the principal element of salvation to be direct knowledge of the hidden divinity, attained via mystical or esoteric insight. Many Gnostic texts deal not in concepts of sin and repentance, but with illusion and enlightenment. Gnosticism likely originated in the late first and early second centuries around Alex ...
