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).

“Stealing is no art. It’s deception, manual dexterity. Presto, and the stuff is gone! That’s how the gypsies were.”  Then he [Martin Luther] spoke about children and said that they should not be allowed to commit thefts. “However, one ought to observe reasonableness. If only cherries, apples, and the like are involved, such childish pranks ought not to be punished so severely; but if money, clothing, or coffers have been seized it is time to punish. My parents kept me under very strict discipline, even to the point of making me timid. For the sake of a mere nut my mother beat me until the blood flowed. By such strict discipline they finally forced me into the monastery; though they meant it heartily well, I was only made timid by it. They weren’t able to keep a right balance between temperament and punishment. One must punish in such a way that the rod is accompanied by the apple. It’s a bad thing if children and pupils lose their spirit on account of their parents and teachers. There have been bungling schoolmasters who spoiled many excellent talents by their rudeness. Ah, what a time we had on Fridays with the lupus and on Thursdays with the parts of Donatus! Then they asked each pupil to parse precisely, according to Donatus, legeris, legere, legitur, and even lecti mei ars. These tests were nothing short of torture. Whatever the method that’s used, it ought to pay attention to the difference in aptitudes and teach in such a way that all children are treated with equal love.” (Luther’s Works, v. 54, p.234, No. 3566A: Children Must Be Disciplined with Understanding, Between March 28 and May 27, 1537)

But when we know and consider that Christ came down from heaven and loved sinners in obedience to the Father, then there springs up in us a bold approach to and firm hope in Christ. We learn that Christ is the real epistle, the golden book, in which we read and learn how he always kept before him the will of the Father. So Christ is the “access to the Father” [Eph. 2:18] as St. Paul says. And John too bears witness that Christ said, “I am the way, and the truth, and the life” [John 14:6]. “I am also the door” [John 10:7] and “no one comes to the Father, but by me” [John 14:6]. Now we see that there is no shorter way to the Father except that we love Christ, hope and trust in him, boldly look to him for everything good, learn to know and praise him. For then it will be impossible that we should have a miserable, frightened, dejected conscience; in Christ it will be heartened and refreshed. But the Scriptures say concerning the sinners: “The wicked shall perish and be driven away like dust” [cf. Ps. 1:4, 6]. Therefore the sinners flee and know not where to go; for when the conscience does not hope and trust in God it cowers and trembles before the purity and righteousness of God. It can have no sweet assurance; it flees and still has nowhere to go unless it finds and catches hold of Christ, the true door and anchor. Yes, this is the way that all Christians should learn. But we go plunging on, taking hold in our own name, with our understanding and reason, and do not see or ever take to heart how kindly, sweetly, and lovingly Christ has dealt with people. For the Father commanded him to do so. This tastes sweet to the faithful soul and it gives all the glory, praise, and honor to the Father through the Son, Christ Jesus. So God has nothing but the best and he offers it to us, weeds us, sustains us, and cares for us through his Son. That’s the way our hearts are changed to follow Christ”  (Luther’s Works, v. 51, p. 46).

Isaiah 52:15. So shall He startle many nations. Here the glory appears again. The prophet proceeds with two members. He says that this Servant is wise and glorious, but there follows another member. He will be without glory and despised. Then follows that His glory will nevertheless be such that He will startle the nations, and the kings will shut their mouths. That is to say, all kings will become ashamed and will know that this King is supreme, and hence they will shut their mouths. They will all humble themselves. Reconcile⁹ this contradiction, that all kings regarded themselves as servants with relation to Him. And yet He will be despised and without glory. Therefore Christ’s kingdom is indeed spiritual and ultimately beyond death.

Sprinkle. This is a Hebraism for “it will be preached.” Sprinkling in the Law denotes preaching, as if to say: “After Christ will have suffered, He will be proclaimed not only among the Jews but also among the Gentiles as water is thrown at and sprinkled on people.” So Peter speaks of “sprinkling with His blood” (1 Peter 1:2) to denote preaching about the blood of Christ. So then we must preach that Christ is both glorious and despised. So Paul preaches Christ alone as misshapen and as crucified. And so He must always be preached, but He shall nonetheless be received even by kings. This is a powerful text against the Jews. They can refer this preaching to no king but Christ.

For that which has not been told them. Paul alludes to this passage when he says that he has not come to Rome because he was kept from it by his preaching in a new place (cf. Rom. 15:22). That place deals with the propagation of the Word, so that His Word might be heard everywhere by kings who shut their mouths. Thus Christ is pictured as being preached even among the Gentiles. Here you clearly see a spiritual kingdom described, one that does not move forward with weapons but with word and recital. So this kingdom of Christ’s suffering and resurrection was promoted in the church by preaching alone. ”  (Luther’s Works, v. 17, p. 217-218).
