Frederick Buechner, Wishful Thinking: A Seeker’s ABC:
Unfermented grape juice is a bland and pleasant drink, especially on a warm afternoon mixed half-and-half with ginger ale. It is a ghastly symbol of the life blood of Jesus Christ, especially when served in individual antiseptic, thimble-sized glasses.
Wine is booze, which means it is dangerous and drunk-making. It makes the timid brave and the reserved amorous. It loosens the tongue and breaks the ice, especially when served in a loving cup. It kills germs. As symbols go, it is a rather splendid one.
