Our Narrative Lectionary has suggested that we take the next four Sundays until the Sunday after Labour Day to look at the section of the catechism dealing with the Ten Commandments. Ordinarily, people would turn to the Small Catechism to do this, but I know everyone in this room already has the Small Catechism memorized, and if not, you can read it on page 1160 of the hymnal, so there's no point to that. Instead, we will read portions of the LARGE Catechism, published by Martin Luther in 1529, and since he compiled a number of sermons to generate the Large Catechism, what makes the most sense is to give the pulpit to Luther....
“For I am the Lord, thy God, strong and jealous, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate Me; and showing mercy unto thousands of them that love Me and keep My commandments.” Although these words relate to all the commandments, yet they are joined to this chief commandment because it is of first importance that men have a right head; for where the head is right, the whole life must be right, and vice versa. Learn, therefore, from these words how angry God is with those who trust in anything but Him, and again, how good and gracious He is to those who trust and believe in Him alone with the whole heart; so that His anger does not cease until the fourth generation, while, on the other hand, His blessing and goodness extend to many thousands, lest you live in such security and commit yourself to chance, as men of brutal heart, who think that it makes no great difference [how they live]. He is a God who will not leave it unavenged if men turn from Him, and will not cease to be angry until the fourth generation, even until they are utterly exterminated. Therefore He is to be feared, and not to be desisted.
He has also demonstrated this in all history, as the Scriptures abundantly show and daily experience still teaches. For from the beginning He has utterly extirpated all idolatry, and, on account of it, both heathen and Jews; even as at the present day He overthrows all false worship, so that all who remain therein must finally perish. Therefore, although proud, powerful, and rich worldlings are now to be found, who boast defiantly of their Mammon, with utter disregard whether God is angry at or smiles on them, and dare to withstand His wrath, yet they shall not succeed, but before they are aware, they shall be wrecked, with all in which they trusted; as all others have perished who have thought themselves more secure or powerful. And just because of such hardened heads who imagine because God connives and allows them to rest in security, that He either is entirely ignorant or cares nothing about such matters, He must deal a smashing blow and punish them, so that He cannot forget it unto children’s children; so that every one may take note and see that this is no joke to Him. For they are those whom He means when He says: Who hate Me, in other words, those who persist in their defiance and pride; whatever is preached or said to them, they will not listen; when they are reproved, in order that they may learn to know themselves and amend before the punishment begins, they become mad and foolish so as to fairly merit wrath, as now we see daily in bishops and princes.
But terrible as are these threatenings, so much the more powerful is the consolation in the promise, that those who cling to God alone should be sure that He will show them mercy that is, show them pure goodness and blessing not only for themselves, but also to their children and children’s children, even to the thousandth generation and beyond that. This ought certainly to move and impel us to risk our hearts in all confidence with God, if we wish all temporal and eternal good, since the Supreme Majesty makes such sublime offers and presents such cordial inducements and such rich promises.
Therefore let everyone seriously take this to heart, lest it be regarded as though a man had spoken it. For to you it is a question either of eternal blessing, happiness, and salvation, or of eternal wrath, misery, and woe. What more would you have or desire than that He so kindly promises to be yours with every blessing, and to protect and help you in all need?
But, alas! here is the failure, that the world believes nothing of this, nor regards it as God’s Word, because it sees that those who trust in God and not in Mammon suffer care and want, and the devil opposes and resists them, that they have neither money, favor, nor honor, and, besides, can scarcely support life; while, on the other hand, those who serve Mammon have power, favor, honor, possessions, and every comfort in the eyes of the world. For this reason, these words must be grasped as being directed against such appearances; and we must consider that they do not lie or deceive, but must come true.
Reflect for yourself or make inquiry and tell me: Those who have employed all their care and diligence to accumulate great possessions and wealth, what have they finally attained? You will find that they have wasted their toil and labor, or even though they have amassed great treasures, they have been dispersed and scattered, so that they themselves have never found happiness in their wealth, and afterwards never reached the third generation. Instances of this you will find a plenty in all histories, also in the memory of aged and experienced people. Only observe and ponder them.
