Well, I've been pursuing some of the text in here so far, and I've noticed no one has called Bob out on this one, so I guess I will.
Bob, you are off on your belief on the "evolution" of God/s and what gnosticism means. Please, allow me to explain.
First, the evolution theory of God/s. You talked about how cavemen viewed Gods as the natural forces (Druidism approach essentially), then they attached human characteristics to them, and then BAM we got us a Greek pantheon! That isn't the case though for religions across the globe. Judaism has existed for thousands of years. Best guesses place it as far back as 1500 B.C. (Scholars best guess as to when Moses would have lived.) So, for well over 3500 years we have one religion that has existed. I'm not an anthropologists, but I've got a feeling that this may be the oldest surviving religion, and the views have not changed that much for it. The arguement could be made that since Abraham believed in other Gods and then changed to one he might have been the one to initiate the transition, but that doesn't make it evolutionary. Cults don't grow large when they compete directly with mainstream view. The only one to do that in the last 1500 years was Scientology, and that was through some pretty nasty tricks.
So, what of the other viewpoint? Gnosticism? Well, here's the problem with gnosticism, it mixes and matches but never keeps things in context. For instance, what if I told you the parable of the Good Samaritan that Jesus told? (To paraphrase that story: A man is mugged on the road and left for dead. A holy man and a priest both ignore him because he is unclean. A Samaritan comes and takes him to an inn and gets him all healed up.) Some would look at that story and just go, "Oh, do nice things. Got it!" But that misses the bigger point that Jesus was making with that parable. He was trying to show Jews that everyone is good, because he showed how someone that Jews disliked would help total strangers yet the holy men would not.
This is the problem with Gnostics and agnostics, they take small parts that sound nice but don't have the same meaning when taken out of context. If you really want to understand this though, you need to go back to how the early Christian church had to fight off the tide of Gnostic Christianity, which was attempting to blend multiple myths into Christianity (this is partly the reason why we have so many pagan festivals with a new Christian flair. The other part was just keeping up the tradition). Entirely new books were written 200 years after Christ attempting to say that they were made by the apostles, yet they claimed things that directly conflicted with the books we had from them directly or from their letters.
I would love to go more into this, but I would first need someone to critique me here. Any takers willing to start a healthy debate?
