Luther emphasized that the Catechisms are meant not just for study by pastors, Church and school, but primarily for the Home. Fathers are to instruct their children and daily to pray the Catechism at home. The Church today cannot make the parents carry out this loving work. The Church can encourage, entreat, portray the value of this teaching. But as the cares and pleasures, the schedules and the concerns of this life take priority, the teaching of the young in the way of truth falters. And the young are taught to enjoy the good of this worldly life but loose hold on sin, repentance, and the forgiveness won by Christ, given to them in Word and Sacrament.
This is not a new problem. It is a persistent and old problem. And through the centuries the teachers of the Church have encouraged fathers, families to take up the Catechism for the benefit of the faith and salvation of their own households.
In 1845 Wilhelm Löhe wrote:
How many, who are acquainted with the Small Catechism, know its preface which together with the introduction to the Large Catechism offers an incomparable, simple, yet truly religious method of catechetical instruction? And again, how many know both prefaces without having observed that the Catechism was written not only for the Church or school, but also for the home?
Home, school and Church become One Church through the dear Catechism. Why is the very important factor of the home omitted? That is the reason why the Catechism is memorized so miserably, and sounds so wooden and flat, because it is not considered as something intended for the home, nor for daily life, nor as a life philosophy, but as a lesson for children and the school room. As a watch-word belongs on the lips of all who are united in one camp, thus the Catechism as a spiritual watch-word should be on the lips of all.
The father, the children, the servants should use it; pray, learn, appreciate it. Thus it will become the cruse of oil of the woman of Zaraphath that does not fail. Yes, when the Catechism again becomes a book for the home, then the people will realize what a flood of strength proceeds from it for the Church and for all her undertakings.
