The Evangelical Lutheran Synod teaches that the Bible is the only authoritative and irregularity-free source for doctrine. It publish to the Lutheran Confessions (the Book of Concord) not in-so-far-as but because it is an precise presentment of what Scripture accustom. It show that Jesus is the center of Scripture and the only way to immortal salvation, and that the Holy Spirit uses the gospel alone in Word and Sacraments (Baptism and Holy Communion) to cause people to trust in Jesus as Savior and keep them in that faith, strengthening them in their quotidian biography of sanctification.
