The Scriptures of the Old and the New Testament as the written Word of God and the only rule and norm of faith and practice.
All the Symbolical Books of the Evangelical Lutheran Church as a true and unadulterated statement and exposition of the Word of God, to wit: the three Ecumenical Creeds (The Apostolic, the Nicene, and the Athanasian), the Unaltered Augsburg Confession, the Apology of the Augsburg Confession, the Smalcald Articles, the Catechisms of Luther, and the Formula of Concord.
