Michael Jensen wrote a interesting article on Gnosticism.
In this article he writes and concludes;
Is there a contemporary form of Gnosticism? The actual Gnostic teachings have had a romantic attraction to a kind of new age Christianity since the discovery of the Nag Hammadi documents. But much more widespread – and far more dangerous – are the ongoing tendencies within mainstream Christianity to cast faith as a higher form of knowledge and to think of the world in dualistic terms.
Though Paul prays for the believers to be filled with the knowledge of God’s will (Col 1:9; see Phil 1:9), there is no sense in which this is secret or higher knowledge into which believers are initiated. Faith is not a matter of inside knowledge. It is a spiritual perception (certainly) of what has been publically declared in the gospel. Yet sometimes we so emphasis learning and knowledge as the path to spiritual growth that we can certainly sound more like Valentinus than Paul.
Likewise – we still have a tendency to see salvation as salvation from the physical world and not salvation with it. The Gnostics denied the resurrection of the body – it was loathsome to them. We may not explicitly, but practically do the same. The Fathers remind us that the God of Jesus Christ, the redeemer is the same as the God who created all things – and not his opponent.
I like what he says, salvation doesn’t take us from the world. Rather we are saved within the world and therefore are to bring about redemption throughout the world.
