These non-canonical accounts are very interesting and the reference you made to Jesus describing matter as a fleeting manifestation that will dissolve back into the spirit is most interesting to me. That's because I have been exploring the concept of dual aspect monism for some time and right now am studying Eddington's views on this where he believes that the single substrate from which mind and matter appear is "spiritual" or the Spirit. As a mostly traditional Christian believer, however, I take these alternative and frequently gnostic accounts in light of the canonical works. Here I find a problem with the idea that Jesus taught the idea of sin is a human construct and foreign to God. How could "the wages of sin is death" be true if sin was just an idea created by humans, presumably to exercise control over each other?
