And let no one think himself too wise for such child’s play. Christ, to train men, had to become man himself. If we wish to train children, we must become children with them. Would to God such child’s play were widely practiced. In a short time we would have a wealth of Christian people whose souls would be so enriched in Scripture and in the knowledge of God that of their own accord they would add more pockets, just as the Loci Communes, and comprehend all Scripture in them. Otherwise, people can go to church daily and come away the same as they went. For they think they need only listen at the time, without any thought of learning or remembering anything. Many a man listens to sermons for three or four years and does not retain enough to give a single answer concerning his faith–as I experience daily. Enough has been written in books, yes; but it has not been driven home to the hearts. (Luther’s Works, v. 53, p.64-67).

When a child begins to understand this it should be encouraged to bring home verses of Scripture from the sermon and to repeat them at mealtime for the parents, even as they formerly used to recite their Latin. And then these verses should be put into the pouches and pockets, just as pennies, groschen, and gulden are put into a purse. For instance, let faiths pouch be for the gulden, and into the first pocket let this verse go: Romans 5 [:12], “… sin came into the world through one man and death through sin….” Also this one: Psalm 51 [:5], “Behold I was brought forth in iniquity, and in sin did my mother conceive me.” These are two Rhenish gulden for the [first] pocket. Into the other pocket go the Hungarian gulden, for example this text, Romans 5 [4:25], “Jesus … was put to death for our trespasses and raised for our justification.” Again John 3 [1:29], “Behold, the Lamb of God, who takes away the sin of the world!” These would be two good Hungarian gulden for the [second] pocket.

Let love’s pouch be the pouch for silver. Into the first pocket shall go the texts concerning well doing, such as Galatians 4 [5:13], “Through love be servants of one another”; Matthew 25 [:40], “As you did it to one of the least of these my brethren, you did it to me.” These would be two silver groschen for the [first] pocket. Into the other pocket shall go this verse: Matthew 5 [:11], “Blessed are you when men … persecute you … on my account”; Hebrews 12 [:6], “For the Lord disciplines him whom he loves, and chastises every son whom he receives.” These are two Schreckenberger for the [second] pocket. (Luther’s Works, v. 53, p.64-67).

Likewise in the Ten Commandments, one must ask: What is meant by the First, the Second, the Third, and the other commandments? One may take these questions from our Betbüchlein where the three parts are briefly explained, or make others, until the heart may grasp the whole sum of Christian truth under two headings or, as it were, in two pouches, namely, faith and love. Faiths pouch may have two pockets. Into one pocket we put the part [of faith] that believes that through the sin of Adam we are all corrupt, sinners, and under condemnation, Romans 5 [:12], Psalm 51 [:5]. Into the other we put the part [of faith that trusts] that through Jesus Christ we all are redeemed from this corruption, sin, and condemnation, Romans 5 [:15–21], John 3 [:16–18]. Loves pouch may also have two pockets. Into the one put this piece, that we should serve and do good to everyone, even as Christ has done for us, Romans 13. Into the other put this piece, that we should gladly endure and suffer all kinds of evil. (Luther’s Works, v. 53, p.64-67).

These three plainly and briefly contain exactly everything that a Christian needs to know. This instruction must be given, as long as there is no special congregation, from the pulpit at stated times or daily as may be needed, and repeated or read aloud evenings and mornings in the homes for the children and servants, in order to train them as Christians. Nor should they only learn to say the words by rote. But they should be questioned point by point and give answer what each part means and how they understand it. If everything cannot be covered at once, let one point be taken up today, and tomorrow another. If parents and guardians won’t take the trouble to do this, either themselves or through others, there never will be a catechism, except a separate congregation be organized as stated above.

In this manner they should be questioned:
What do you pray?
Answer: The Our Father.
What is meant when you say: Our Father in Heaven?
Answer: That God is not an earthly, but a heavenly Father who would make us rich and blessed in heaven.
What is meant by: Hallowed be thy name?
Answer: That we should honor his name and keep it from being profaned.
How do we profane or dishonor his name?
Answer: When we, who should be his children, live evil lives and teach and believe what is wrong.
And so on, what is meant by the kingdom of God, how it comes, what is meant by the will of God, by daily bread, etc., etc.
So in the Creed:
what do you believe?
Answer: I believe in God the Father, … to the end.
Thereafter from point to point, as time permits, one or two points at a time. For instance:
What does it mean to believe in God the Father Almighty?
Answer: It means to trust in him with all your heart and confidently to expect all grace, favor, help, and comfort from him, now and forever.
What does it mean to believe in Jesus Christ his Son?
Answer: It means to believe with the heart that we would all be eternally lost if Christ had not died for us, etc. (Luther’s Works, v. 53, p.64-67).
