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 ******st 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 ****** 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.
