Just as the Christian doctrine of God should be rooted in the divine economy, so too Christian worship should rehearse the divine economy. God’s actions in history are the basis for both the knowledge and worship of the triune God. Liturgy, like theology, must not “float off into abstractions” about God. In other words, Christian liturgy is fundamentally an act of anamnesis, an act of rehearsing God’s actions in history: past and future, realized and promised. Christians identify the God they worship by naming God as the agent of particular actions in history. Worship proceeds better by rehearsing eventful narratives of divine action—viewed iconically as reliable windows into divine life—than by re-stating rational deductions or abstract ideas.
