Catechesis: On Catechesis

For the reason we exercise such diligence in preaching the catechism often* is so that it may be taught to our youth, not in a high and clever way, but briefly and with the greatest simplicity. In this way it will enter the mind easily and be fixed in the memory.—LC Shorter Intro, par. 27

*The custom at Wittenberg in Luther’s time was to preach through the Catechism four times a year, using the Ember days.
