In a Lutheran school, certainly in a Lutheran classical school, children are taught the catechism, which is built around the key texts of the Ten Commandments, the Apostle’s Creed, and the Lord’s Prayer.
These are accompanied with explanations and questions geared to help children understand, in the words of the great refrain of Luther’s Small Catechism, “What does this mean?” Thus, we have the Sixth Commandment (by Augustine’s, the Catholic, and the Lutheran numbering):
You shall not commit adultery.
What does this mean? We should fear and love God so that we lead a sexually pure and decent life in what we say and do, and husband and wife love and honor each other.
