gnōsis, knowledge) refers to diverse, syncretistic religious movements in antiquity consisting of various belief systems generally united in the teaching that the material cosmos was created by an imperfect god, the demiurge with some of the supreme God's pneuma; this being is frequently identified with Yahweh, (as opposed to the Gospel according to the Hebrews) and is contrasted with a superior entity, referred to by several terms including Pleroma and Godhead. Depictions of the demiurge—the term originates with Plato's Timaeus—vary from being as an embodiment of evil, to being merely imperfect and as benevolent as its inadequacy permits. Gnosticism was a dualistic religion, influenced by and influencing Hellenic philosophy, Judaism (see Notzrim), and Christianity; however, by contrast, later strands of the movement, such as the Valentinians, held a monistic world-view. This, along with the varying treatments of the demiurge, may be seen as indicative of the variety of positions held within the category. - Source: Wikipedia
