The Ten Commandments part 2b
By Martin Luther
Thou shalt not take the name of the Lord, thy God, in vain.
Exodus 20:7
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. (Leviticus 5:1, 4;)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(Psalm 139:11-12; Job 34:22; Psalm 90:8; John 3:19;). 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(Isaiah 5:20; Psalm 52:1-4; Proverbs 17:15;). 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. ( Genesis 6:5; Romans 1:18, 29;)
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.(Psalm 50:15; Zechariah 13:9;Isaiah 58:2) For all this is bringing 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(Matthew 6:9; Luke 11:2;).
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. (Proverbs 17:13; Psalm 109:2-3, 29; Luke 9:25; Luke 19:26; Mark 8:36;)
