"We teach children to look to God in faith and to care for their neighbor in love by means of the Six Chief Parts and the Seven Liberal Arts."
The first part of this definition is drawn from Luther's post-communion collect. It represents the two tables of the Law ("Love the Lord your God with all your heart soul strength and mind . . . and love your neighbor as yourself"), but it does so in the context of Word and Sacraments, the means by which the Lord enables His people both "to will and to do according to His good pleasure," (Philippians 2:13). Where there is forgiveness, there is life and salvation.
The second part of the definition refers to the six chief parts of Luther's Small Catechism (The Ten Commandments, The Apostles' Creed, The Lord's Prayer, Holy Baptism, Holy Absolution, and Holy Communion) and the seven liberal arts (Grammar, Logic, Rhetoric, Arithmetic, Geometry, Astronomy, and Music).
Our intention is not that you have to try to remember this definition, but rather that you won't be able to forget it.
