Here is an interesting take on the terms mention in it. I invite you to lead the way in a discussion on them.
Then I have to say that for the next several days -- right through Sunday -- I'm going to be up to my ears in Church stuff, including a paint-ball tournament between the Catholic Student ministry at UVA and that of AU -- which supposedly I am going to organize, make safe, etc. (We're going to kick their butts, just sayin')
So I'm distressed that this fascinating (to me) topic comes up when I really ought to be off line, organizing a tournament, preparing two talks, and generally doing stuff that keeps me from theology.
I'm going to review your excellent study, and maybe I can add something to the discussion tomorrow AM. Or maybe later tonight.
