What I take to be "fallen" is the failure to conform one's will to God's. The point I was trying to make from Letter #181 was that in ME Tolkien said that it was God's will that the world change. The words were that change is "the unfolding of the story and
to refuse this is of course against the design of God." If to refuse change is against the design of God, then God's will must be for change.
It's not so much the "changing world" that is important...it's the will of God. I mean, if God willed that the Elves should have jelly beans and the Elves keep trying to get rid of jelly beans, Elves would still be fallen because they are not conformed to the will of God. Of course, since it's the will of God, the Elves would always find themselves with jelly beans and they would have jelly bean anxiety until they just accepted God's will in the matter.
Right.... I get that. What are we debating again and why?
