I teach Luther's Small Catechism as part of an undergraduate theology class on the theology of Martin Luther and Thomas Aquinas. I use it as a way to carry out the ideas of the Freedom of a Christian into the ordinary. The following are 10 great things that emerge from the teaching of the first three articles: Commandments, Creed, and Lord's Prayer.
1. Luther puts the "fear and love of God" at the core of the commandments.
2. He lodges the language of justification of the ungodly in discussion of God's gift of creation.
3. He makes the commandments about the neighbor, the other, as well as each repetitions of the first commandment.
4. Unconditional self-giving of God the Father, Jesus, and the Spirit.
5. Everyday life, quotidian grace.
6. "not with silver and gold."
7. "I cannot by my own reason..."
