"This is the essence of the sacramental: paying attention, noticing, discovering that material things remind us of - and point us to - the things we cannot see but that have ultimate eternal reality and value.
God and his truth and beauty are like a sun that fills the sky. Huge verities flame off from its center like the flaming tongues of a corona, utterly overwhelming us in our insignificance. Yet, as with the inherent meaning of the materials of the Tabernacle, he may become visible to those who pay attention, whose eyes of belief and imagination are open, in a form as unthreatening and taken for granted as a baby or a dove or a lamb or a loaf of bread or a flick of prism color on a wall."
