The Large Catechism is the clearest exposition of Luther’s teaching to the church. In masterful fashion, he unfolds the Ten Commandments, the Apostles’ Creed, the Lord’s Prayer, Baptism, and the Lord’s Supper. It is one of the most important and foundational texts of the church, and should be familiar to all Christians.
We’ve formatted to the text of the Large Catechism from the Concordia Triglotta, a public domain text. It is available as a free download, or for $5 from Lulu.
