With ever-increasing energy Luther, therefore, urged the parents to study the Catechism in order to be able to teach it to their children. In his sermons on the Ten Commandments, 1516, he admonishes them to bring up their children in the fear and admonition of the Lord. "But alas," he exclaims, "how has not all this been corrupted! Nor is it to be wondered at, since the parents themselves have not been trained and educated." In a sermon of 1526: "Here are two doctrines, Law and Gospel. Of them we preach frequently, but very few there are who take it to heart. I hear that many are still so ignorant that they do not know the Ten Commandments nor are able to pray. It plainly shows that they are altogether careless. Parents ought to see what their children and family are doing. In the school at home they should learn these three. I hear that in the city, too, there are wicked people. We cannot enter the homes; parents, masters, and mistresses ought to be sufficiently skilled to require their children and servants to say the prayers before retiring. But they do not know any themselves. What, then, avails it that we do a great deal of preaching concerning the kingdom of Christ? I thought conditions had improved. I admonish you master--for it is your duty--to instruct the servants, the mistress, the maids, and the children; and it is publicly preached in church for the purpose that it may be preached at home." (W. 20 485.) In his sermon of September 14, 1528, Luther declares that the Catechism is the laymen's Bible, which every one must know who wishes to be considered a Christian and to be admitted to the Lord's Supper. He then proceeds: "Hence all children should behave accordingly, and learn. And you parents are bound to have your children learn these things. Likewise you lords, take pains that your family, etc. Whoever does not know these things does not deserve any food. These five points are a brief summary of the Christian doctrine. When the question is put, 'What is the First Commandment?' every one should be able to recite: 'Namely this,'" etc. (W. 30, 1, 27.) Exhorting the people to attend the Catechism-services, Luther declared November 29, 1528: "Think not, ye housefathers, that you are freed from the care of your household when you say: 'Oh, if they are unwilling to go [to Catechism instruction], why should I force them? I am not in need of it.' You have been appointed their bishop and house-pastor; beware lest you neglect your duty toward them!" (27, 444.) On the following day, beginning the sermons he had announced Luther said: "Therefore I have admonished you adults to have your children and your servants, attend it [the Catechism-sermon], and also be present yourselves; otherwise we shall not admit you to Holy Communion. For if you parents and masters will not help us we shall accomplish little by our preaching. If I preach an entire year, the household comes, gapes at the walls and windows of the church, etc.
