Remember and help to raise up good people, that you, father, may raise up a devout son, you, mother, a devout daughter, who in turn will raise up their children in piety. Thus the servants will also be well trained. A prince and the cities need good people. The prince needs councilors, the cities need pastors and learned men.
Therefore, do not say, as some people are saying these days: Priestcraft doesn’t count any more. If you note that your child can become an able boy, send him to school. If you do not do this, you will have to give an account, and you are a rogue who is against the prince and the city and disobedient to your God. Hitherto scholars have been educated in order to become canons. Now we must devote far more care to educating the children in order that we may find people who are capable of serving a country in its secular government and the cities in spiritual government as preachers and lectors. You see what murderous harm you do to the sovereign prince and the fatherland when you keep gifted boys away from study. (Luther’s Works, v. 51 p. 151)
