Well, I have a paper topic for my Religious Studies class. Since we are studying 9-11 as a religious event, I thought of something like, "9-11 Memorialization as a Function of Sacramental Awareness." "Sacramental Awareness" is defined as the extent to which ordinary things are seen as divine, or reflections of the divine Presence. The book that I lifted the concept from is called Living from the Center. The author is not a Christian, in my estimation (Orthodox confessional Christianity, see Apostles' Creed) but he's trained in theology, so his knowledge is useful for thinking theologically and sacramentally.
