I admonish you to give these eight days to your Lord and permit your household and children to attend, and you yourself may also come and profit by this instruction. No one knows as much as he ought to know. For I myself am constrained to drill it every day. You know that we did not have it under the Papacy. Buy while the market is at the door; some day you will behold the fruit. We would, indeed, rather escape the burden, but we do it for your sakes." (34, 2, 195.) 90. Cooperation of Parents Urged by Luther. In order to bring the instruction of the young into vogue, Luther saw that church, school, and home must needs cooperate. The home especially must not fail in this. Accordingly, in his admonitions, he endeavored to interest the fathers and mothers in this work. He was convinced that without their vigorous cooperation he could achieve but little. In his _German Order of Worship,_ 1526, we read: "For if the parents and guardians of the young are unwilling to take such pains with the young, either personally or through others, Catechism [catechetical instruction] will never be established." (W. 19, 76.) In this he was confirmed by the experiences he had while on his tour of visitation. If the children were to memorize the Catechism and learn to understand it, they must be instructed and questioned individually, a task to which the Church was unequal, and for the accomplishment of which also the small number of schools was altogether inadequate. Parents, however, were able to reach the children individually. They had the time and opportunity, too, morning, noon, and evening, at the table, etc. Furthermore, they had the greatest interest in this matter, the children being their own flesh and blood. And they, in the first place, were commanded by God to provide for the proper training of their children. The fathers and mothers, therefore, these natural and divinely appointed teachers of the children, Luther was at great pains to enlist for the urgent work of instructing the young. They should see that the children and servants did not only attend the Catechism-sermons in church, but also memorized the text and learned to understand it. The Christian homes should again become home-churches, home-schools, where the house-fathers were both house-priests and house-teachers performing the office of the ministry there just as the pastors did in the churches.
