"A new aspect of the eucharist comes to life when we think of it as a sign that we are waiting for the day of the Lord’s return. To wait is a quite distinct kind of activity. It means recognizing that someone else is the prime mover or principal actor. It means admitting that we ourselves are in secondary roles, so secondary that we do not know the time schedule. It means living in patience and hope. This is the spirit of much of the Bible, especially of the Psalms which are such a regular part of traditional public and private prayer. This is the spirit in which the New Testament speaks of breaking the bread and drinking the cup until the Lord comes."
