Therefore it is the duty of every father of a family to question and examine his children and servants at least once a week and to ascertain what they know of [this catechism], or are learning, and, if they do not know it, to keep them faithfully at it.
Luther adds:
However, it is not enough for them to comprehend and recite these parts according to the words only, but the young people should also be made to attend the preaching, especially during the time which is devoted to the Catechism, that they may hear it explained and may learn to understand what every part contains, so as to be able to recite it as they have heard it, and, when asked, may give a correct answer, so that the preaching may not be without profit and fruit.[2]
