And when they do this, they often speak of the shift in polarized terms, as a turning from exotericism to esotericism, from institutionalism to inner life, from religion to spirituality. Why, only lastnight I read this: "...well from what i know Orthodox Christianity doesn’t agree with Gnosticism because they often have different views on what happened to Jesus and his teachings. Gnosticism has a more mystical approach to things and orthodox doesn’t like it."
But I don't buy into that metanarrative so easily. In response to that comment, I said "It’s misleading to put the difference down to 'Gnosticism has a more mystical approach to things and orthodox doesn’t like it.' Because the fact of the matter is there are many varieties of orthodox / non-Gnostic mysticism within Christianity. So you’re statement only holds true for some streams of Christianity at best, not all."
I highlight this because I think it's important to sort between false and genuine differences at this point. There are differences between Christianity and Gnosticism, but it's not in the mysticism.
