The content and meaning of classical worship tells and acts out the story of God’s saving work in history, culminating in the work of Christ to overthrow the powers of evil and to ultimately establish his kingdom over creation. This story is in our hymns and songs, in our prayers and testimonies, and, supremely in the reading of Scripture, preaching, and the Eucharist.
