Gnosticism was rooted out of Christianity as heretical and false teaching ... so it's not a good idea to try and bring it back in right now ... :-)
Gnosticism (Greek: γνῶσις gnōsis, knowledge) refers to diverse, syncretistic religious movements in antiquity consisting of various belief systems generally united in the teaching that the cosmos was created by an imperfect god, the demiurge with some of the supreme God's pneuma; this being is frequently identified with the Abrahamic God, (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.
The gnōsis referred to in the term is a form of mystic, revealed, esoteric knowledge through which the spiritual elements of humanity are reminded of their true origins within the superior Godhead, being thus permitted to escape materiality. Consequently, within the sects of gnosticism only the pneumatics or psychics obtain gnōsis; the hylic or Somatics, though human, being incapable of perceiving the higher reality, are unlikely to attain the gnōsis deemed by gnostic movements as necessary for salvation. Jesus of Nazareth is identified by some Gnostic sects as an embodiment of the supreme being who became incarnate to bring gnōsis to the earth. In others (e.g. the Notzrim and Mandaeans) he is considered a mšiha kdaba or "false messiah" who perverted the teachings entrusted to him by John the Baptist. Still other traditions identify Mani and Seth, third son of Adam and Eve, as salvific figures.
Whereas Gnosticism has been considered by scholars to originate as a branch of Christianity, alternate theories have proposed traces of Gnostic systems existed some centuries before the Christian Era, thus predating the birth of Jesus. The movement spread in areas controlled by the Roman Empire and Arian Goths, and the Persian Empire; it continued to develop in the Mediterranean and Middle East before and during the second and third centuries. Conversion to Islam and the Albigensian Crusade (1209–1229) greatly reduced the remaining number of Gnostics throughout the Middle Ages, though a few Mandaean communities still exist. Gnostic ideas became influential in the philosophies of various esoteric mystical movements of the late 19th and 20th centuries in Europe and North America, including some that explicitly identify themselves as revivals or even continuations of earlier gnostic groups.
In the formation of Christianity, various sectarian groups, labeled "gnostics" by their opponents, emphasised spiritual knowledge (gnosis) over faith (pistis) in the teachings and traditions of the established community of Christians. These sectarians considered the most essential part of the process of salvation to be this personal knowledge, in contrast to faith as an outlook in their world view along with faith in the ecclesiastical authority. These break away groups were branded minuth by Hebrews (see the Notzrim) and heretics by the Fathers of the early church due to teaching this type of authority rejection referred to as antinomianism. The knowledge of these sectarian groups is contested by orthodox Christian theology as speculative knowledge derived from religio-philosophical systems rather than knowledge derived from revelation coming from faith. Gnosis itself is and was obtained through understanding at which one can arrive via inner experience or contemplation such as an internal epiphany for example. For the various sectarian gnostics, gnosis was obtained as speculative gnosis, instigated by the contemplation of their religio-philosophical (Cosmological, salvational and rational) systems. These systems were pagan (folk) in origin and syncretic in nature. The gnostic sectarians vilified the concepts of a subjective creator God (Plato's demiurge) and objective creator God (one that creates ex-nihilo) as in the Judeo-Christian God (creator) and sought to reconcile the individual to their own personal deification (henosis), making each individual God. As such the gnostic sects made a duality out of the difference between the activities of the spirit (nous), called noesis (insight), and those of faith.
During the early formation of Christianity, church authorities (Fathers of the Church) exerted considerable amounts of energy attempting to weed out what were considered to be false doctrines (e.g. Irenaeus' On the Detection and Overthrow of False Gnosis). The gnostics (as one sectarian group) held views which were incompatible with the emerging Ante-Nicene community. Among Christian heresiologists, the concept of false gnosis was used to denote different Pagan, Jewish or Christian belief systems (e.g. the Eleusinian Mysteries or Glycon) and their various teachings of what was deemed religio-philosophical systems of knowledge, as opposed to authentic gnosis (see below, Gnosis among the Greek Fathers). The sectarians used gnosis or secret knowledge to reject the traditions of the established community or church. The authorities throughout the community criticized this antinomianism as inconsistent with the communities teachings. Hence sectarians and followers of gnosticism were first rejected by the Jewish communities of the Mediterranean (see the Notzrim 139–67 BCE), then by the Christian communities and finally by the late Hellenistic philosophical communities (see Neoplatonism and Gnosticism).
BTTT
I am just saying that Gnosis from the Dead Sea Scrolls goes into the Cosmological Divine Realm of GOD and I actually read all of it, and don’t see where it contradicts the Holy Scriptures.....
