Today's Communion antiphon, John 6.54: Whoever eats my flesh and drinks my blood has eternal life, says the Lord, and I will raise him up on the last day. If Jesus had said, "Whoever eats my flesh and drinks my blood, I mean symbolically, of course, would have eternal life . . ." – anyone could have picked up some bread to eat and some wine to drink anywhere anytime and have eternal life.
