"Therefore, beginning with Genesis 4:26 and continuing through the history of the faith, true believers have proclaimed their faith to the world through their worship. With the call of Abraham to begin the covenant program of bringing blessing to the world, that proclamation became clearer, richer, and more powerful... proclamation has ever since been an integral part of worship. Now in the worship of the new covenant the preaching of Christ crucified is the necessary correlative to celebrating Holy Communion. Whenever proclamation has been lost to worship, worship loses its way and becomes empty ritual. Both the drama of the ritual and the interpretation by the proclamation are necessary for the full worship of God. The Word gives the ritual meaning, and the ritual gives visible form to the Word."
