The Second Commandment.
Thou shalt not take the name of the Lord, thy God, in vain.
"53] 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. [GJ - Thus synod officials put a known adulterer into the pulpit while claiming he has a Scriptural divorce.]
54] 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.
55] 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, subtile 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.
56] 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.
57] 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 vain. 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. 58] Now, alas! it is a common calamity in all the world 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.
59] 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 they 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."
