Lutheranism

Explore the Book of Concord, the collection of confessional documents that define Lutheran theology. The Augsburg Confession (1530), presented to Emperor Charles V, articulates the core Lutheran doctrines of justification by faith alone, the two natures of Christ, and the proper distinction between law and gospel. Luther's Small Catechism (1529) provides accessible instruction in the Ten Commandments, Apostles' Creed, Lord's Prayer, and sacraments. These texts shaped Protestant Christianity across Northern Europe and the globe.
