Martin Luther wrote the catechism as a teaching tool of Christian doctrine and faith and families. It is a powerful tool for the Christian life because of it's own brief, clear summary of God's Word on the essentials of the Christian faith. Students of Lutheran theology look to the Luther's Small catechism for a concise presentation of the Six Chief Parts of Christian Doctrine written by Luther, and an explanation of Luther's Small Catechism for further clarification and study. The new narrative and reflective elements of the explanation section will appeal to those who want to learn more about Lutheran doctrine. The Sprial bound Edition includes the same written content of the 2017 edition. The Spiral Bound Edition lays flat when open, allowing it to remain open to a desired page, and includes margins wide enough to make note-taking easy.
