Dominic,
You make some very interesting points. However, I have to disagree with you on at least one point. I do not grant that being made in God's image necessitates that we are made of the divine substance. When theologians use the phrase "creatio ex nihilo" they mean only to say that God did not use previously existing materials; God not only created all that we see but also the "stuff" out of which it is made. Nor when theologians say that God created out of "nothing" do we mean that God used some substance called "nothing." For one thing this just opens up another whole can of worms; predicating existence to "nothing," i.e., calling "nothing" a "something." So, I do not think that the concept of the image of God necessitates a pantheism or panentheism, much less that all that we see is merely an emanation of God, or the "One," (e.g. Plotinus).
Your comments about the image of God and BAD pictures is an interesting point. Theologians have said for millennia that something has gone terribly wrong with humanity's ability to reflect acurately the image of God. I could go on but I don't want to "preach."
I would like to read more about your comment on theodicy. I think you mean that if everything that exists emanates from the divine substance (which I do not think I must grant), then whatever is or whatever happens is just the outworking of God. Thus if we grant that God is Good, then everything that happens is Good by definition (even bad photos). I think this is what you mean but I may be mistaken. Please correct me if I am wrong.
What I would like to hear someone comment on is the question of aesthetics itself. Certainly someone in the forum would be willing to contribute their thoughts on the notion of beauty itself and from where it derives. This could be an interesting conversation.
