At bread and wine God discloses his whole story for those who know how to see. Yes, bread and wine are symbols, but they are not empty. The ancient fathers taught that symbols participate in the reality they re-present. . . . Bread and wine signify and perform God’s story and communicate the benefits of God’s story to us.
