That is: Thou shalt have [and worship] Me alone as thy God. What is the force of this, and how is it to be understood? What does it mean to have a god? or, what is God? Answer: A god means that from which we are to expect all good and to which we are to take refuge in all distress, so that to have a God is nothing else than to trust and believe Him from the [whole] heart; as I have often said that the confidence and faith of the heart alone make both God and an idol. If your faith and trust be right, then is your god also true; and, on the other hand, if your trust be false and wrong, then you have not the true God; for these two belong together faith and God. That now, I say, upon which you set your heart and put your trust is properly your god.
Therefore it is the intent of this commandment to require true faith and trust of the heart which settles upon the only true God and clings to Him alone. That is as much as to say: "See to it that you let Me alone be your God, and never seek another," i.e.: Whatever you lack of good things, expect it of Me, and look to Me for it, and whenever you suffer misfortune and distress, creep and cling to Me. I, yes, I, will give you enough and help you out of every need; only let not your heart cleave to or rest in any other.
This I must unfold somewhat more plainly, that it may be understood and perceived by ordinary examples of the contrary. Many a one thinks that he has God and everything in abundance when he has money and possessions; he trusts in them and boasts of them with such firmness and assurance as to care for no one. Lo, such a man also has a god, Mammon by name, i.e., money and possessions, on which he sets all his heart, and which is also the most common idol on earth. He who has money and possessions feels secure, and is joyful and undismayed as though he were sitting in the midst of Paradise. On the other hand, he who has none doubts and is despondent, as though he knew of no God. For very few are to be found who are of good cheer, and who neither mourn nor complain if they have not Mammon. This [care and desire for money] sticks and clings to our nature, even to the grave.
So, too, whoever trusts and boasts that he possesses great skill, prudence, power, favor friendship, and honor has also a god, but not this true and only God. This appears again when you notice how presumptuous, secure, and proud people are because of such possessions, and how despondent when they no longer exist or are withdrawn. Therefore I repeat that the chief explanation of this point is that to have a god is to have something in which the heart entirely trusts.
Besides, consider what in our blindness, we have hitherto been practicing and doing under the Papacy. If any one had toothache, he fasted and honored St. Apollonia [lacerated his flesh by voluntary fasting to the honor of St. Apollonia]; if he was afraid of fire, he chose St. Lawrence as his helper in need; if he dreaded pestilence, he made a vow to St. Sebastian or Rochio, and a countless number of such abominations, where every one selected his own saint, worshiped him, and called for help to him in distress. Here belong those also, as, e.g., sorcerers and magicians, whose idolatry is most gross, and who make a covenant with the devil, in order that he may give them plenty of money or help them in love-affairs, preserve their cattle, restore to them lost possessions, etc. For all these place their heart and trust elsewhere than in the true God, look for nothing good to Him nor seek it from Him.
Thus you can easily understand what and how much this commandment requires, namely, that man's entire heart and all his confidence be placed in God alone, and in no one else. For to have God, you can easily perceive, is not to lay hold of Him with our hands or to put Him in a bag [as money], or to lock Him in a chest [as silver vessels]. But to apprehend Him means when the heart lays hold of Him and clings to Him. But to cling to Him with the heart is nothing else than to trust in Him entirely. For this reason He wishes to turn us away from everything else that exists outside of Him, and to draw us to Himself, namely, because He is the only eternal good. As though He would say: Whatever you have heretofore sought of the saints, or for whatever [things] you have trusted in Mammon or anything else, expect it all of Me, and regard Me as the one who will help you and pour out upon you richly all good things.
Lo, here you have the meaning of the true honor and worship of God, which pleases God, and which He commands under penalty of eternal wrath, namely, that the heart know no other comfort or confidence than in Him, and do not suffer itself to be torn from Him, but, for Him, risk and disregard everything upon earth. On the other hand, you can easily see and judge how the world practices only false worship and idolatry. For no people has ever been so reprobate as not to institute and observe some divine worship; every one has set up as his special god whatever he looked to for blessings, help, and comfort.
Thus, for example, the heathen who put their trust in power and dominion elevated Jupiter as the supreme god; the others, who were bent upon riches, happiness, or pleasure, and a life of ease, Hercules, Mercury, Venus or others; women with child, Diana or Lucina, and so on; thus every one made that his god to which his heart was inclined, so that even in the mind of the heathen to have a god means to trust and believe. But their error is this that their trust is false and wrong for it is not placed in the only God, besides whom there is truly no God in heaven or upon earth. Therefore the heathen really make their self-invented notions and dreams of God an idol, and put their trust in that which is altogether nothing. Thus it is with all idolatry; for it consists not merely in erecting an image and worshiping it, but rather in the heart, which stands gaping at something else, and seeks help and consolation from creatures saints, or devils, and neither cares for God, nor looks to Him for so much good as to believe that He is willing to help, neither believes that whatever good it experiences comes from God.
Besides, there is also a false worship and extreme idolatry, which we have hitherto practiced, and is still prevalent in the world, upon which also all ecclesiastical orders are founded, and which concerns the conscience alone that seeks in its own works help, consolation, and salvation, presumes to wrest heaven from God, and reckons how many bequests it has made, how often it has fasted, celebrated Mass, etc. Upon such things it depends, and of them boasts, as though unwilling to receive anything from God as a gift, but desires itself to earn or merit it superabundantly, just as though He must serve us and were our debtor, and we His liege lords. What is this but reducing God to an idol, yea, [a fig image or] an apple-god, and elevating and regarding ourselves as God ? But this is slightly too subtle, and is not for young pupils.
But let this be said to the simple, that they may well note and remember the meaning of this commandment, namely, that we are to trust in God alone, and look to Him and expect from Him naught but good, as from one who gives us body, life, food, drink, nourishment, health, protection, peace, and all necessaries of both temporal and eternal things. He also preserves us from misfortune, and if any evil befall us, delivers and rescues us, so that it is God alone (as has been sufficiently said) from whom we receive all good, and by whom we are delivered from all evil. Hence also, I think, we Germans from ancient times call God (more elegantly and appropriately than any other language) by that name from the word good as being an eternal fountain which gushes forth abundantly nothing but what is good, and from which flows forth all that is and is called good.
For even though otherwise we experience much good from men, still whatever we receive by His command or arrangement is all received from God. For our parents, and all rulers, and every one besides with respect to his neighbor, have received from God the command that they should do us all manner of good, so that we receive these blessings not from them, but, through them, from God. For creatures are only the hands, channels, and means whereby God gives all things, as He gives to the mother breasts and milk to offer to her child, and corn and all manner of produce from the earth for nourishment, none of which blessings could be produced by any creature of itself.
Therefore no man should presume to take or give anything except as God has commanded, in order that it may be acknowledged as God's gift, and thanks may be rendered Him for it, as this commandment requires. On this account also these means of receiving good gifts through creatures are not to be rejected, neither should we in presumption seek other ways and means than God has commanded. For that would not be receiving from God, hut seeking of ourselves.
Let every one, then, see to it that he esteem this commandment great and high above all things, and do not regard it as a joke. Ask and examine your heart diligently, and you will find whether it cleaves to God alone or not. If you have a heart that can expect of Him nothing but what is good, especially in want and distress, and that, moreover renounces and forsakes everything that is not God, then you have the only true God. If on the contrary, it cleaves to anything else, of which it expects more good and help than of God, and does not take refuge in Him, but in adversity flees from Him, then you have an idol, another god.
In order that it may be seen that God will not have this commandment thrown to the winds, but will most strictly enforce it, He has attached to it first a terrible threat, and then a beautiful, comforting promise which is also to be urged and impressed upon young people, that they may take it to heart and retain it:
[Exposition of the Appendix to the First Commandment.]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 (as we shall hereafter learn), 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 [Sardanapaluses and Phalarides, who surpass even the Persians in wealth] 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, i.e., 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 the 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.
Saul was a great king, chosen of God and a godly man; but when he was established on his throne, and let his heart decline from God, and put his trust in his crown and power, he had to perish with all that he had, so that none even of his children remained. David, on the other hand, was a poor, despised man, hunted down and chased, so that he nowhere felt secure of his life; yet he had to remain in spite of Saul, and become king. For these words had to abide and come true, since God cannot lie or deceive. Only let not the devil and the world deceive you with their show, which indeed remains for a time, but finally is nothing.
Let us, then, learn well the First Commandment, that we may see how God will tolerate no presumption nor any trust in any other object, and how He requires nothing higher of us than confidence from the heart for everything good, so that we may proceed right and straightforward and use all the blessings which God gives no farther than as a shoemaker uses his needle, awl, and thread for work, and then lays them aside, or as a traveler uses an inn, and food, and his bed only for temporal necessity, each one in his station, according to God's order, and without allowing any of these things to be our food or idol. Let this suffice with respect to the First Commandment, which we have had to explain at length, since it is of chief importance, because, as before said, where the heart is rightly disposed toward God and this commandment is observed, all the others follow.
As the First Commandment has instructed the heart and taught [the basis of] faith, so this commandment leads us forth and directs the mouth and tongue to God. For the first objects that spring from the heart and manifest themselves are words. Now, as I have taught above how to answer the question, what it is to have a god, so you must learn to comprehend simply the meaning of this and all the commandments, and to apply it to yourself. If, then, it be asked: How do you understand the Second Commandment, or what is meant by taking in vain, or misusing God's name? answer briefly thus: It is misusing God's name when we call upon the Lord God no matter in what way, for purposes of falsehood or wrong of any kind. Therefore this commandment enjoins this much, that God's name must not be appealed to falsely, or taken upon the lips while the heart knows well enough, or should know, differently; as among those who take oaths in court, where one side lies against the other. For God's name cannot be misused worse than for the support of falsehood and deceit. Let4this remain the exact German and simplest meaning of this commandment.
From this every one can readily infer when and in how many ways God's name is misused, although it is impossible to enumerate all its misuses. Yet, to tell it in a few words, all misuse of the divine name occurs, first, in worldly business and in matters which concern money, possessions, honor, whether it be publicly in court, in the market, or wherever else men make false oaths in God's name, or pledge their souls in any matter. And this is especially prevalent in marriage affairs where two go and secretly betroth themselves to one another, and afterward abjure [their plighted troth].
But. the greatest abuse occurs in spiritual matters, which pertain to the conscience, when false preachers rise up and offer their Lying vanities as God's Word. Behold, all this is decking one's self out with God's name, or making a pretty show, or claiming to be right, whether it occur in gross, worldly business or in sublime, subtle matters of faith and doctrine. And among liars belong also blasphemers, not alone the very gross, well known to every one, who disgrace God's name without fear (these are not for us, but for the hangman to discipline); but also those who publicly traduce the truth and God's Word and consign it to the devil. Of this there is no need now to speak further.
Here, then, let us learn and take to heart the great importance of this commandment, that with all diligence we may guard against and dread every misuse of the holy name, as the greatest sin that can be outwardly committed. For to lie and deceive is in itself a great sin, but is greatly aggravated when we attempt to justify it, and seek to confirm it by invoking the name of God and using it as a cloak for shame, so that from a single lie a double lie, nay, manifold lies, result.
For this reason, too, God has added a solemn threat to this commandment, to wit: For the Lord will not hold him guiltless that taketh His name in van. That is: It shall not be condoned to any one nor pass unpunished. For as little as He will leave it unavenged if any one turn his heart from Him, as little will He suffer His name to be employed for dressing up a lie. Now alas! it is a common calamity in all the word that there are as few who are not using the name of God for purposes of Lying and all wickedness as there are those who with their heart trust alone in God. For by nature we all have within us this beautiful virtue, to wit, that whoever has committed a wrong would like to cover up and adorn his disgrace, so that no one may see it or know it; and no one is so bold as to boast to all the world of the wickedness he has perpetrated, all wish to act by stealth and without any one being aware of what thy do. Then, if any one be arraigned, the name of God is dragged into the affair and must make the villainy look like godliness, and the shame like honor. This is the common course of the world, which, like a great deluge, has flooded all lands. Hence we have also as our reward what we seek and deserve: pestilences wars, famines, conflagrations, floods, wayward wives, children, servants, and all sorts of defilement. Whence else should so much misery come? It is still a great mercy that the earth bears and supports us.
Therefore, above all things, our young people should have this commandment earnestly enforced upon them, and they should be trained to hold this and the First Commandment in high regard; and whenever they transgress, we must at once be after them with the rod and hold the commandment before them, and constantly inculcate it, so as to bring them up not only with punishment, but also in the reverence and fear of God.
Thus you now understand what. it is to take God's name in vain, that is (to recapitulate briefly), either simply for purposes of falsehood, and to allege God's name for something that is not so, or to curse, swear, conjure, and, in short, to practice whatever wickedness one may. Besides this you must also know how to use the name [of God] aright. For when saying: Thou shalt not take the name of the Lord thy God, in vain, He gives us to understand at the same time that it is to be used properly. For it has been revealed and given to us for the very purpose that it may be of constant use and profit. Hence it is a natural inference, since using the holy name for falsehood or wickedness is here forbidden, that we are, on the other hand, commanded to employ it for truth and for all good, as when one swears truly where there is need and it is demanded. So also when there is right teaching, and when the name is invoked in trouble or praised and thanked in prosperity etc.; all of which is comprehended summarily and commanded in the passage Ps. 50, 15: Call upon Me in the days of trouble; I will deliver thee, and thou shalt glorify Me. For all this is bringing 't into the service of truth, and using it in a blessed way, and thus His name is hallowed, as we pray in the Lord's Prayer.
Thus you have the sum of the entire commandment explained. And with this understanding the question with which many teachers have troubled themselves has been easily solved, to wit, why swearing is prohibited in the Gospel, and yet Christ, St. Paul, and other saints often swore. The explanation is briefly this: We are not to swear in support of evil, that is, of falsehood, and where there is no need or use; but for the support of good and the advantage of our neighbor we should swear. For it is a truly good work, by which God is praised, truth and right are established, falsehood is refuted, peace is made among men, obedience is rendered, and quarrels are settled. For in this way God Himself interposes and separates between right and wrong, good and evil. If one part swears falsely, he has his sentence that he shall not escape punishment, ad though it be deferred a long time, he shall not succeed; that all that he may gain thereby will slip out of his hands, and he will never enjoy it; as I have seen in the case of many who perjured themselves in their marriage-vows, that they have never had a happy hour or a healthful day, and thus perished miserably in body, soul, and possessions.
Therefore I advise and exhort as before that by means of warning and threatening, restraint and punishment, the children be trained betimes to shun falsehood, and especially to avoid the use of God's name in its support. For where they are allowed to do as they please, no good will result, as is even now evident that the world is worse than it has ever been and that there is no government, no obedience, no fidelity, no faith, but only daring, unbridled men, whom no teaching or reproof helps; all of which is God's wrath and punishment for such wanton contempt of this commandment.
On the other hand, they should be constantly urged and incited to honor God's name, and to have it always upon their lips in everything that may happen to them or come to their notice: For that is the true honor of His Name, to look to it and implore it for all consolation, so that (as we have heard above) first the heart by faith gives God the honor due Him, and afterwards the lips by confession.
This is also a blessed and useful habit and very effectual against the devil, who is ever about us, and lies in wait to bring us into sin and shame, calamity and trouble, but who is very loath to hear God's name, and cannot remain long where it is uttered and called upon from the heart. And, indeed, many a terrible and shocking calamity would befall us if, by our calling upon His name, God did not preserve us. I have myself tried it, and learned by experience that often sudden great calamity was immediately averted and removed during such invocation. To vex the devil, I say, we should always have this holy name in our mouth, so that he may not be able to injure us as he wishes.
For this end it is also of service that we form the habit of daily commending ourselves to God, with soul and body, wife, children, servants, and all that we have, against every need that may occur; whence also the blessing and thanksgiving at meals, and other prayers, morning and evening, have originated and remain in use. Likewise the practices of children to cross themselves when anything monstrous or terrible is seen or heard, and to exclaim: "Lord God, protect us!" "Help, dear Lord Jesus!" etc. Thus, too, if any one meets with unexpected good fortune, however trivial, that he say: "God be praised and thanked; this God has bestowed on me!" etc., as formerly the children were accustomed to fast and pray to St. Nicholas and other saints. This would be more pleasing and acceptable to God than all monasticism and Carthusian sanctity.
Behold, thus we might train our youth in a childlike way and playfully in the fear and honor of God, so that the First and Second Commandments might be well observed and in constant practice. Then some good might take root, spring up and bear fruit, and men grow up whom an entire land might relish and enjoy. Moreover, this would be the true way to bring Up children well as long as they can become trained with kindness and delight. For what must be enforced with rods and blows only will not develop into a good breed and at best they will remain godly under such treatment no longer than while the rod is upon their back.
But this [manner of training] so spreads its roots in the heart that they fear God more than rods and clubs. This I say with such simplicity for the sake of the young, that it may penetrate their minds. For since we are preaching to children, we must also prattle with them. Thus we have prevented the abuse and have taught the right use of the divine name, which should consist not only in words, but also in practices and life, so that we may know that God is well pleased with this and will as richly reward it as He will terribly punish the abuse.
