Gnosticism is a heresy which is made up of a diverse set of beliefs. It is the teaching based on the idea of gnosis (a Koine Greek word meaning "secret knowledge"), or knowledge of transcendence arrived at by way of internal, intuitive means. While Gnosticism thus relies on personal religious experience as its primary authority, early "Christian" Gnostics did adopt their own versions of authoritative Scriptures, such as those found at Nag Hammadi in Egypt.
What we know about Gnosticism comes from Irenaeus who studied twenty of the most influential Gnostic writers and defined and criticized their beliefs. Other early church fathers, such as Tertullian and Origen also provide information regarding Gnostic beliefs. Lastly, many Gnostic writings were discovered at the Nag Hammadi Library. Nag Hammadi is a town in Upper Egypt near ancient Chenoboskion and 13 codices were discovered about 1945.
The following information is taken from Olson, The Story of Christian Theology, p. 37.
Matter or materiality
Gnostics believed that matter, whether it be the physical universe or the humanly body, is evil. It is obvious that there is a great tension between spirit and matter. This effects many of their beliefs and especially the way they perceive(d) the world and God's interactions with it.
God is wholly transcendent, that is, he is far removed from his creation. He did not create the material universe because it was instead created by an evil or lesser God, sometimes called a "demiurge". God is thus too perfect and pure to have much to do with the evilness of the material universe.
Gnostics believed that human beings were "sparks" or "droplets" of the very same spiritual substance (or essence) that God is. Somehow we we became trapped in our physical bodies from which we are to escape.
All Gnostics agreed that The Fall was identical to the fall into matter. In other words, creation and The Fall coincide. "As long as spirits are trapped in physical bodies and materiality, they will be subject to sin, which is caused by ignorance of their true nature and home."
Gnosticism commonly held that "salvation is to escape from the bondage of the material existence and travel back to the home from which souls/spirits have fallen." God initiates salvation because he wants to draw back the stray bits and pieces of himself, and so he sends forth an emanation of himself - "a spiritual redeemer" - who comes down from heaven and gives an attempt to teach some of the "divine sparks of Spirit" what their true identity is and where their real home lies. Once they are awakened by this redeemer they can then begin their journey back home. "Salvation is by knowledge - self-knowledge."
Lastly, as far as most scholars know, Gnostics considered themselves Christians and saw Jesus as a heavenly messenger. However, they rejected the idea of God becoming incarnate (God becoming a man), dying and rising bodily. "These beliefs were considered unspiritual and against true wisdom because they entangled spirit with matter." Most Gnostics believe that whoever entered Jesus at his baptism left him before he died on the cross.
Gnosticism's present existence
This heretical view is still in existence today, both in various secretive cults and in such pop religious movements as astrology or alchemy.
The Masonic movement has been referred to as a Gnostic movement. The popular book _The Da Vinci Code_ (2003, Doubleday) by Dan Brown promotes Gnostic ideas as it attempts to undermine orthodox Christianity.
