Even Unto Death: The Spiritual Armory of the Evangelical Lutheran Church Chapter 6

6. What Does It Mean to Be Liturgical? The Cadence of the Faithful
Military forces employ cadences, rhythmic verses, to ensure troops stay in formation, maintain a quick pace, promote esprit de corps, and instill unit cohesion during marches. As the formation marches to a cadence recalling heroes and battles, a member in front of the formation bears the unit guidon. The guidon, a small flag, serves as the standard for the unit or force. Words set to rhythm and symbols inspire generation after generation of military members. The words of Scripture, reflected in the worship service, establish the rhythmic cadence for Evangelical Lutherans.
