Of the Second Commandment

Thou shalt not take the Name of the Lord thy God in vain.

 

Q. What does the second commandment forbid us?

A. It forbids us, first, to swear to any thing we know, or even doubt to be false.

2. To swear without necessity, although the thing be true and just. S. Mat. 5. 34, 35, 37

3. To swear what we do not intend to perform; or to neglect fulfilling, when we can, a lawful oath. Jerem. 4.2.

4. To swear we shall do what is bad, or not do what is good.

5. To conceal the truth from our lawful superior, when he requires of us to tell it; in which case, we do not only sin, but we are likewise obliged to repair all the damage and harm, which happened thereby to our neighbour.

6. To swear by God or the saints blood, wounds or limbs.

7. To give to the Devil, or curse at any rate ourselves, our soul or body, our children, servants, cattle, or any thing else whatsoever.

8. To wish either temporal or spiritual harm to ourselves or others.

9. To make a vow without intending to fulfill it; or to make a vow of doing what is evil, or displeasing to God.

10. To break a lawful vow.

 

Q. From hence it appears, that it is an ill custom to be given to swearing?

A. It is a very bad custom; wherefore, those foolish people sin greatly, who matter not whether they have truth or falsehood on their side, or swear to the truth itself without necessity.

 

Q. What should our speech be, in order to avoid sin?

A. Yes, yes; no, no: as our Saviour taught and commanded us; for what is more than these, proceedeth from evil. S. Mat. 5.37.

1 Q. What does the Second Commandment: Thou shalt not take the Name of God in vain, forbid?

A. The Second Commandment: Thou shalt not take the Name of God in vain, forbids us: (1) To utter the Name of God irreverently; (2) To blaspheme God, the Blessed Virgin or the Saints; (3) To take false, unnecessary, or unlawful oaths.

3 Q. What is blasphemy?

A. Blasphemy is a horrible sin which consists in words or acts of contempt or malediction against God, the Blessed Virgin, the Saints, or sacred things.

4 Q. Is there any difference between blasphemy and imprecation?

11 Q. What sin does he commit who swears falsely?

A. He who swears falsely commits a mortal sin, because he grievously dishonours God, the Infinite Truth, by calling Him to witness what is false.

12 Q. What does the Second Commandment command us to do?

A. The Second Commandment commands us to honour the Holy Name of God as well as to keep our oaths and vows.

13 Q. What is a vow?

A. A vow is a promise made to God regarding something which is good, within our power, and better than its opposite, and to the keeping of which we bind ourselves just as if it had been commanded us.

14 Q. If the keeping of a vow were to become very difficult, in whole or in part, what is to be done?

A. Commutation or dispensation, may be sought from one's Bishop or from the Pope, according to the character of the vow.

15 Q. Is it a sin to break a vow?

A. It is a sin to break a vow and therefore we should not make vows without mature reflection, nor, as a rule, without the advice of our confessor or other prudent person, so as not to expose ourselves to the danger of sinning.

A. Vows are made to God alone; we may, however, promise God to do something in honour of our Lady or the Saints.

EXPLANATION OF THE SECOND COMMANDMENT

 

S. Let us proceed now to the Second Commandment. What is meant by "Thou shall not take the name of the Lord thy God in vain"?

T. This Commandment treats on the honor and dishonoring of God that is done by words. It is commanded to honor Him and forbidden to dishonor Him. For that reason, this Commandment can be divided into four ways that God is honored by words and four that He is dishonored by them. Firstly, God is honored by words when we pronounce His name affected by charity, but He is dishonored when we take it in vain. Secondly, we honor Him by swearing oaths, and dishonor Him by perjury. Thirdly, we honor Him when taking vows and dishonor Him by violating them. Fourthly and lastly, we honor Him with invocation and praise but dishonor Him by blasphemy and cursing.

S. Explain the first part to me.

T. One use the name of God, the Blessed Virgin and the Saints by speaking simply and do so well or wickedly. For those who more intensely love God frequently remember God and speak about Him; they do this from great devotion and affection, just as it is done in the Epistles of St. Paul, wherein, as often as the name of Our Lord Jesus Christ is read, we know that St. Paul bore great devotion and affection in heart in which he divulged it in speech. On the other hand, there are others who, from a wicked custom, when they are either angry or joke rashly advance the name of God, or of some saint, and in fact nothing else comes into their mind. These certainly act wickedly because in a certain measure they tread the most Holy Name of God underfoot. As an example, even though I will not declare all things by an example, those who do such things are the same as if someone having an exceedingly precious garment should carelessly use it too much namely in every time and place.

S. Now explain the object of the second part, which treats on oaths.

T. To swear an oath is nothing other than to invoke God as a witness to the truth; to do this well three things must be present, obviously the truth, but also justice and judgment, in the same way that God Himself taught us through the mouth of Jeremiah. And just as by swearing an oath under due circumstances God is honored, so on the other hand, He is exceedingly dishonored if someone were to swear an oath without truth, justice or judgment. One who does this, signifies that God is either not conscious of his affairs or certainly makes him the patron of a lie or iniquity.

S. Tell me more in particular, what is it to swear with the truth?

T. For one to swear with the truth it is necessary that he assert nothing under oath other than what he knows for certain to be true; nor can anyone affirm with an oath something to be true which they know is false or that they certainly do not know is true. They do the same that promise something with an oath but do not think to carry it out.

S. What does it mean to swear with justice?

T. It is simply to promise under oath to do something which is just and right. And therefore, those who swear themselves to avenge injuries inflicted on themselves or to do something that displeases God gravely sin; nor must it stand or be thought that by such promises one obliges himself to these things in another manner, since no one is obliged to do evil, since the Divine Laws constrain us to not do nothing against them.

S. What does it mean to swear with judgment?

T. It is merely to swear with prudence and maturity by considering whether something is unsuitable to invoke God as a witness, unless it is for necessary affairs of great importance, and to do that with great fear and reverence. For this reason they sin who blurt out oaths in some trivial affair or in comedy and jokes. They also incur perjury who have a bad habit of frequently swearing, because it is one of the greatest sins that one can commit. For this reason, both Christ in the Gospel and St. James absolutely forbid us to swear without necessity. The saints assign this reason, that swearing an oath should be a remedy for the weakness of human trust, in as much as men may believe each other with great difficulty; for that reason it must be used like a medicine which is usually taken as rarely as possible.

S. Explain to me the third part of this Commandment, which is on Vows.

T. A vow is a promise made to God in some good matter and for the sake of the Divine Majesty. Here three things must be considered. The first is that a vow is a promise, for that reason it is not sufficient to ratify a vow for it to only have been proposed, much less desired, but it is necessary that an express promise be made by word or at least in heart. The second is that this vow is made to God, Whom vows most properly consider. Therefore, when a vow is made to the Blessed Virgin or to another saint, it must be understood that the vow was principally made to God, but to the honor of the Blessed Virgin or the saints, in whom God dwells in a peculiar and by far more excellent manner than in the rest of His creatures. This is why when a vow is made to some saint, it is nothing other than a promise made to God in memory of that saint which must be honored by some sacrifice honoring God Himself in the saint. The third is that a vow cannot he made about just anything, rather about some good and for the sake of God, such as virginity, voluntary poverty, and things of this sort. For that reason one who vows a sin, or some work that does not pertain to the worship of God, or even something good which might be an impediment to a greater good, insofar as he would not do something for the sake of the Divine Majesty thus dishonors God and offends against this Second Commandment. Just the same one would also gravely infringe upon this commandment if he were to make a vow that he does not fulfil as quickly as possible. Because God commands in Scripture that one who begins a vow should not only fulfil it but also do it without delay.

S. Explain the last part to me, which treats on the praise of God and also blasphemy.

T. In this last part of the Commandment, God commands us not to blaspheme His Holy Name, but rather to praise and bless it. And firstly, in as much as it attains to praise there is no difficulty, seeing that it is manifest that every good proceeds from God and all His works are full of wisdom, justice and mercy; it is reasonable in the first place that in all things, He should be praised and blessed. In as much as it considers blasphemy, you should know that it is nothing other than an injury inflicted upon God by words, either directly or against the saints, and there are six kinds of blasphemy. The first is when something is attributed to God that is not suited to Him; for example, that he has horns or similar inept things. Second, when something suited to God is denied to Him, such as power, wisdom, justice or any other of His attributes, so that if someone were to say that God cannot do this or that, or cannot see, or is not just. The third, is when something that is proper to God is attributed to some creature. Some men do this when they say the devil is prescient of future things or performs true miracles. The fourth, is when someone curses God, His Mother, or the other saints. The fifth, is when someone names some limb of Christ or the saints to inflict injury upon them, just as if they were ignominious things to them, even as these acts are to us. The sixth, is when something pertaining to Christ or the saints themselves is mocked; some do this when they swear by the beard of Christ or St. Peter or something like it, which are all assailed by the hatred of demons and the perversity of men.

S. I ask you to tell me how grave a sin is blasphemy?

T. It is so grave that it is nearly the gravest of all. This can be gathered from the punishment constituted for blasphemies. In the Old Testament, God commanded blasphemers to be stoned on the spot by the whole people, and civil laws punish blasphemers with death. St. Gregory relates about a five year-old boy that had learned to blaspheme; he was not corrected by his father and expired in the lap of his father, and his soul was visibly brought down to hell by demons that had appeared. This is not read about any other sin. For that reason we must very assiduously beware lest we so gravely offend the Divine Majesty. It is not difficult to abstain from this sin, since no usefulness or utility is obtained from it, as is the case with certain other sins. Rather, only damnation comes from it. Although one must never sin no matter what advantage or delight one could ultimately obtain from it.

Catechism promulgated by Pope John Paul II in 1992.

Source: CCC 2142 – 2167

The Second Commandment

You shall not take the name of the Lord your God in vain.72

You have heard that it was said to the men of old, "You shall not swear falsely….” But I say to you, Do not swear at all.73

I. The Name of the Lord is Holy

2142 The second commandment prescribes respect for the Lord's name. Like the first commandment, it belongs to the virtue of religion and more particularly it governs our use of speech in sacred matters.

2143 Among all the words of Revelation, there is one which is unique: the revealed name of God. God confides his name to those who believe in him; he reveals himself to them in his personal mystery. the gift of a name belongs to the order of trust and intimacy. "The Lord's name is holy." For this reason man must not abuse it. He must keep it in mind in silent, loving adoration. He will not introduce it into his own speech except to bless, praise, and glorify it.74

2144 Respect for his name is an expression of the respect owed to the mystery of God himself and to the whole sacred reality it evokes. the sense of the sacred is part of the virtue of religion:

Are these feelings of fear and awe Christian feelings or not? . . . I say this, then, which I think no one can reasonably dispute. They are the class of feelings we should have - yes, have to an intense degree - if we literally had the sight of Almighty God; therefore they are the class of feelings which we shall have, if we realize His presence. In proportion as we believe that He is present, we shall have them; and not to have them, is not to realize, not to believe that He is present.75

2145 The faithful should bear witness to the Lord's name by confessing the faith without giving way to fear.76 Preaching and catechizing should be permeated with adoration and respect for the name of our Lord Jesus Christ.

2146 The second commandment forbids the abuse of God's name, i.e., every improper use of the names of God, Jesus Christ, but also of the Virgin Mary and all the saints.

2147 Promises made to others in God's name engage the divine honor, fidelity, truthfulness, and authority. They must be respected in justice. To be unfaithful to them is to misuse God's name and in some way to make God out to be a liar.77

2148 Blasphemy is directly opposed to the second commandment. It consists in uttering against God - inwardly or outwardly - words of hatred, reproach, or defiance; in speaking ill of God; in failing in respect toward him in one's speech; in misusing God's name. St. James condemns those "who blaspheme that honorable name [of Jesus] by which you are called."78 The prohibition of blasphemy extends to language against Christ's Church, the saints, and sacred things. It is also blasphemous to make use of God's name to cover up criminal practices, to reduce peoples to servitude, to torture persons or put them to death. the misuse of God's name to commit a crime can provoke others to repudiate religion.

Blasphemy is contrary to the respect due God and his holy name. It is in itself a grave sin.79

2149 Oaths which misuse God's name, though without the intention of blasphemy, show lack of respect for the Lord. the second commandment also forbids magical use of the divine name.

[God's] name is great when spoken with respect for the greatness of his majesty. God's name is holy when said with veneration and fear of offending him.80

II. Taking the Name of the Lord in Vain

2150 The second commandment forbids false oaths. Taking an oath or swearing is to take God as witness to what one affirms. It is to invoke the divine truthfulness as a pledge of one's own truthfulness. An oath engages the Lord's name. "You shall fear the LORD your God; you shall serve him, and swear by his name."81

2151 Rejection of false oaths is a duty toward God. As Creator and Lord, God is the norm of all truth. Human speech is either in accord with or in opposition to God who is Truth itself. When it is truthful and legitimate, an oath highlights the relationship of human speech with God's truth. A false oath calls on God to be witness to a lie.

2152 A person commits perjury when he makes a promise under oath with no intention of keeping it, or when after promising on oath he does not keep it. Perjury is a grave lack of respect for the Lord of all speech. Pledging oneself by oath to commit an evil deed is contrary to the holiness of the divine name.

2153 In the Sermon on the Mount, Jesus explained the second commandment: "You have heard that it was said to the men of old, 'You shall not swear falsely, but shall perform to the Lord what you have sworn.' But I say to you, Do not swear at all.... Let what you say be simply 'Yes' or 'No'; anything more than this comes from the evil one."82 Jesus teaches that every oath involves a reference to God and that God's presence and his truth must be honored in all speech. Discretion in calling upon God is allied with a respectful awareness of his presence, which all our assertions either witness to or mock.

2154 Following St. Paul,83 The tradition of the Church has understood Jesus' words as not excluding oaths made for grave and right reasons (for example, in court). "An oath, that is the invocation of the divine name as a witness to truth, cannot be taken unless in truth, in judgment, and in justice."84

2155 The holiness of the divine name demands that we neither use it for trivial matters, nor take an oath which on the basis of the circumstances could be interpreted as approval of an authority unjustly requiring it. When an oath is required by illegitimate civil authorities, it may be refused. It must be refused when it is required for purposes contrary to the dignity of persons or to ecclesial communion.

III. The Christian Name

2156 The sacrament of Baptism is conferred "in the name of the Father and of the Son and of the Holy Spirit."85 In Baptism, the Lord's name sanctifies man, and the Christian receives his name in the Church. This can be the name of a saint, that is, of a disciple who has lived a life of exemplary fidelity to the Lord. the patron saint provides a model of charity; we are assured of his intercession. the "baptismal name" can also express a Christian mystery or Christian virtue. "Parents, sponsors, and the pastor are to see that a name is not given which is foreign to Christian sentiment."86

2157 The Christian begins his day, his prayers, and his activities with the Sign of the Cross: "in the name of the Father and of the Son and of the Holy Spirit. Amen." the baptized person dedicates the day to the glory of God and calls on the Savior's grace which lets him act in the Spirit as a child of the Father. the sign of the cross strengthens us in temptations and difficulties.

2158 God calls each one by name.87 Everyone's name is sacred. the name is the icon of the person. It demands respect as a sign of the dignity of the one who bears it.

2159 The name one receives is a name for eternity. In the kingdom, the mysterious and unique character of each person marked with God's name will shine forth in splendor. "To him who conquers . . . I will give a white stone, with a new name written on the stone which no one knows except him who receives it."88 "Then I looked, and Lo, on Mount Zion stood the Lamb, and with him a hundred and forty-four thousand who had his name and his Father's name written on their foreheads."89

IN BRIEF

2160 "O Lord, our Lord, how majestic is your name in all the earth" (Ps 8:1)!

2161 The second commandment enjoins respect for the Lord's name. the name of the Lord is holy.

2162 The second commandment forbids every improper use of God's name. Blasphemy is the use of the name of God, of Jesus Christ, of the Virgin Mary, and of the saints in an offensive way.

2163 False oaths call on God to be witness to a lie. Perjury is a grave offence against the Lord who is always faithful to his promises.

2164 "Do not swear whether by the Creator, or any creature, except truthfully, of necessity, and with reverence" (St. Ignatius of Loyola, Spiritual Exercises, 38).

2165 In Baptism, the Christian receives his name in the Church. Parents, godparents, and the pastor are to see that he be given a Christian name. the patron saint provides a model of charity and the assurance of his prayer.

2166 The Christian begins his prayers and activities with the Sign of the Cross: "in the name of the Father and of the Son and of the Holy Spirit. Amen."

2167 God calls each one by name (cf Isa 43:1).

The Second Commandment of God.

“Thou shalt not take the name of the Lord thy God in vain."

1. What does the Second Commandment forbid?

The Second Commandment forbids all profanation of the holy name of God.

2. How do we profane the name of God?

We profane the name of God, 1. By irreverently pronouncing it; 2. By deriding religion; 3. By blasphemy; 4. By sinful swearing, and by cursing: and 5. By breaking vows.

3. How do we sin by irreverently pronouncing God's holy name?

By pronouncing the name of God in jest, or in anger, or in any other careless manner.

This applies also to other names and words worthy of reverence, as, the name of the Blessed Virgin, the Holy Cross, the Holy Sacraments, etc., and to the words of the Holy Scripture, which are never to be abused in jest, or by way of derision.

“The Lord will not hold him guiltless that shall take the name of the Lord his God in vain.” (Exod . 20, 7.)

4. How do we sin by deriding religion?

By scoffing at religion, at the rites or ceremonies of the Church, or by turning them into ridicule, in which cases we may also become guilty of blasphemy.

“Knowing this first, that in the last days there shall come deceitful scoffers, walking after their own lusts. You, therefore, brethren, knowing these things before, take heed, lest being led aside by the error of the unwise, you fall from your own steadfastness.” (2. Pet. 3, 3. 17.)

5. What is meant by blasphemy?

By blasphemy is meant contemptuous and abusive language uttered against God, the Saints, or holy things.

This sin is so great that, in the Old Law, those who were found guilty of it, were put to death. “He that blasphemeth the name of the Lord, dying let him die: all the multitude shall stone him.” (Levit. 24, 16.) - How Sennacherib, King of the Assyrians, was punished for blaspheming the Lord, see 4. Kings 19.

6. May we also become guilty of blasphemy by thoughts?

Yes, when we voluntarily think contemptuously of God, or of the Saints.

7. What is swearing or taking an oath?

Swearing or taking an oath is to call the Omniscient God to witness, that we speak the truth, or that we will keep our promise.

We call God also to witness, when we swear by Heaven, by the Holy Cross, or by the Gospel, etc. “Whosoever shall swear by the temple, sweareth by it, and by Him that dwelleth in it; and he that sweareth by Heaven, sweareth by the throne of God, and by Him that sitteth thereon.” (Matt. 23, 21. 22.)

8. How do we sin by swearing?

We sin by swearing, 1. When we swear falsely, or in doubt; 2. When we swear, or induce others to swear, without necessity; 3. When we swear to do what is evil, or to omit what is good; and 4. When we do not keep our oath, although we can keep it.

“Thou shalt swear in truth, and in judgment, and in justice. " (Jer. 4, 2.)

9. What means swearing falsely, or in doubt?

It means, 1. To assert with an oath that something is true, though we know that it is untrue, or do not know whether it is true or not; 2. To promise with an oath something which we do not intend to perform.

10. What are we to think of perjury, or a false oath?

Perjury, especially in a court of justice, is one of the greatest crimes; because he who commits it, 1. Mocks God's Omniscience, Sanctity, and Justice; 2.; Destroys the last means of preserving truth and faith among men; and 3. Almost solemnly renounces God and calls down His vengeance upon him.

“And the Lord said to me: This flying volume which thou see, is the curse that goth forth over the face of the earth; for everyone that sweareth shall be judged by it. I will bring it forth, said the Lord of Hosts, and it shall come to the house of him that sweareth falsely by My name, and it shall remain during his house, and shall consume it, with the timber thereof, and the stones thereof.” (Zach. 5, 3. 4. Comp. Ezech. 17.)

11. When a person has sworn to do something evil, or to omit something that is good, is he bound to keep such an oath?

No; for as it was a sin to take such an oath, so it would be another sin to keep it. Ex.: Herod. (Mark 6, 23-28.)

12. What do you mean by cursing?

Cursing means, to wish any evil either to ourselves, or to our neighbour, or to any of God's creatures, whereby the name of God is frequently dishonoured.

Cursing is something very hateful, which betrays a rude, angry temper. From the mouth of a Christian, or Child of God, nothing but “blessing" ought to come forth (1. Pet. 3, 9.). Cursing is at the same time an oath, when we call upon God to punish us, if we speak an untruth.

13. What is a vow?

A vow is a voluntary promise made to God, to do something that is agreeable to Him, although there be no obligation to do it.

Accordingly, a vow is, 1. A real promise, by which we deliberately bind ourselves, and not a mere desire, or resolution; 2. A promise made to God, because it is to God alone, we make vows; and 3. A promise to do something that is agreeable to God; therefore, it cannot be anything trifling, sinful, or injurious to others; nor anything good by which something better may be prevented, or higher duties neglected.

14. What does the Church teach with regard to vows?

1. That they please God, because they are voluntary offerings made to Him. Thus, God kindly accepted the vows of the Patriarch Jacob, and of the pious Anna, the mother of Samuel, and granted their petitions.

“And Jacob made a vow, saying: If God shall be with me, and I shall return prosperously to my father's house, of all things that Thou shalt give to me, I will offer tithes to Thee.” (Gen. 28, 20–22,)

“Anna made a vow, saying: O Lord of Hosts, if Thou wilt be mindful of me, and wilt give to Thy servant a man - child, I will give him to the Lord all the days of his life.” (1. Kings 1, 11.)

2. That it is a sacred duty to keep them unless it be impossible to do so. People should, therefore, be very cautious about making vows, and should, in general, ask advice of their Confessor, or any other prudent Priest. “If thou hast vowed anything to God, defer not to pay it. It is much better not to vow, than after a vow not to perform the things promised.” (Eccles.5, 3. 4.)

15. Is it sufficient not to dishonour the name of God?

No; we must also honour and revere it, i.e., we must gratefully praise it, devoutly call upon it, steadily confess it, and exert ourselves to promote its honour.

Application. - Carefully avoid the shameful habit of cursing and swearing. "A man that sweareth much, shall be filled with iniquity, and a scourge shall not depart from his house." (Ecclus. 23, 12.) On the contrary, often invoke with devotion the names of Jesus and Mary, especially in temptations against purity.

Catechism of Trent III.2 The Second Commandment


Catechism of Trent III.2 The Second Commandment

Published in 1566 CE.

Source: Catechism of the Council of Trent, III.2, p. 382-395. Trans: J.A. McHugh & C.J. Callan. Joseph F. Wagner, Inc.: New York, 1923 [10th Printing, 1947]

THE SECOND COMMANDMENT: "Thou shalt not take the name of the lord thy god in vain"

Why This Commandment Is Distinct From The First

The second Commandment of the divine law is necessarily comprised in the first, which commands us to worship God in piety and holiness. For he who requires that honour be paid him, also requires that he be spoken of with reverence, and must forbid the contrary, as is clearly shown by these words of the Lord in Malachy: The son honoureth the father and the servant his master if then I be a father, where is my honour?
However, on account of the importance of the obligation, God wished to make the law, which commands His own divine and most holy name to be honoured, a distinct Commandment, expressed in the clearest and simplest terms.

Importance Of Instruction On This Commandment

The above observation should strongly convince the pastor that on this point it is not enough to speak in general terms; that the importance of the subject is such as to require it to be dwelt upon at considerable length, and to be explained to the faithful in all its bearings with distinctness, clearness and accuracy.
This diligence cannot be deemed superfluous, since there are not wanting those who are so blinded by the darkness of error as not to dread to blaspheme His name, whom the Angels glorify. Men are not deterred by the Commandment laid down from shamelessly and daringly outraging His divine Majesty every day, or rather every hour and moment of the day. Who is ignorant that every assertion is accompanied with an oath and teems with curses and imprecations? To such lengths has this impiety been carried, that there is scarcely anyone who buys, or sells, or transacts business of any sort, without having recourse to swearing, and who, even in matters the most unimportant and trivial, does not profane the most holy name of God thousands of times.
It therefore becomes more imperative on the pastor not to neglect, carefully and frequently, to admonish the faithful how grievous and detestable is this crime.

Positive Part of this Commandment

But in the exposition of this Commandment it should first be shown that besides a negative, it also contains a positive precept, commanding the performance of a duty. To each of these a separate explanation should be given; and for the sake of easier exposition what the Commandment requires should be first set forth, and then what it forbids. It commands us to honour the name of God, and to swear by it with reverence It prohibits us to condemn the divine name, to take it in vain, or swear by it falsely, unnecessarily or rashly.
In the part which commands us to honour the name of God, the command, as the pastor should show the faithful, is not directed to the letters or syllables of which that name is composed, or in any respect to the mere name; but to the meaning of a word used to express the Omnipotent and Eternal Majesty of the Godhead, Trinity in Unity. Hence we easily infer the superstition of those among the Jews who, while they hesitated not to write, dared not to pronounce the name of God, as if the divine power consisted in the four letters, and not in the signification.
Although this Commandment uses the singular number, Thou shalt not take the name of God, this is not to be understood to refer to any one name, but to every name by which God is generally designated. For He is called by many names, such as the Lord, the Almighty, the Lord of hosts, the King of kings, the Strong, and by others of similar nature, which we meet in Scripture and which are all entitled to the same and equal veneration.

Various Ways Of Honouring God's Name

It should next be taught how due honour is to be given to the name of God Christians, whose tongues should constantly celebrate the divine praises, are not to be ignorant of a matter so important, indeed, most necessary to salvation The name of God may be honoured in a variety of ways; but all may be reduced to those that follow.

Public Profession Of Faith

In the first place, God's name is honoured when we publicly and confidently confess Him to be our Lord and our God; and when we acknowledge and also proclaim Christ to be the author of our salvation.

Respect For The Word Of God

(It is also honoured) when we pay a religious attention to the word of God, which announces to us His will; make it the subject of our constant meditation; and strive by reading or hearing it, according to our respective capacities and conditions of life, to become acquainted with it.

Praise And Thanksgiving

Again, we honour and venerate the name of God, when, from a sense of religious duty, we celebrate His praises, and under all circumstances, whether prosperous or adverse, return Him unbounded thanks. Thus spoke the Prophet Bless the Lord, O my soul, and never forget all he hath done for thee. Among the Psalms of David there are many, in which, animated with singular piety towards God, he chants in sweetest strains the divine praises. There is also the example of the admirable patience of Job, who, when visited with the heaviest and most appalling calamities, never ceased, with lofty and unconquered soul, to give praise to God. When, therefore, we labour under affliction of mind or body, when oppressed by misery and misfortune, let us instantly direct all our thoughts, and all the powers of our souls, to the praises of God, saying with Job Blessed be the name of the Lord.

Prayer

The name of God is not less honoured when we confidently invoke His assistance, either to relieve us from our afflictions, or to give us constancy and strength to endure them with fortitude. This is in accordance with the Lord's own wishes. Call upon me, He says, in the day of trouble: I will deliver thee, and thou shalt glorify me. We have illustrious examples of such supplications in many passages of Scripture, and especially in the sixteenth, forty­third, and one hundred and eighteenth Psalms.

Oaths

Finally, we honour the name of God when we solemnly call upon Him to witness the truth of what we assert. This mode of honouring God's name differs much from those already­ enumerated. Those means are in their own nature so good, so desirable, that our days and nights could not be more happily or more holily spent than in such practices of piety. I will bless the Lord at all times, says David, his praise shall be always in my mouth. On the other hand, although oaths are in themselves good, their frequent use is by no means praiseworthy.
The reason of this difference is that oaths have been instituted only as remedies to human frailty, and a necessary means of establishing the truth of what we assert. As it is inexpedient to have recourse to medicine unless, when it becomes necessary, and as its frequent use is harmful; so with regard to oaths, it is not profitable to have recourse to them, unless there is a weighty and just cause; and frequent recurrence to them, far from being advantageous, is on the contrary highly prejudicial. Hence the excellent observation of St Chrysostom: Oaths were introduced among men, not at the beginning of the world, but long after; when vice had spread far and wide over the earth; when all things were disturbed and universal confusion reigned out; when, to complete human depravity, almost all mankind debased the dignity of their nature by the degrading service of idols. Then at length it was that the custom of oaths was introduced. For the perfidy and wickedness of men was so great that it was with difficulty that anyone could be induced to credit the assertion of another, and they began to call on God as a witness.

Meaning Of An Oath

Since in explaining this part of the Commandment the chief object is to teach the faithful how to render an oath reverential and holy, it is first to be observed, that to swear, whatever the form of words may be, is nothing else than to call God to witness; thus to say, God is witness, and By God, mean one and the same thing.
To swear by creatures, such as the holy Gospels, the cross, the names or relics of the Saints, and so on, in order to prove our statements, is also to take an oath. Of themselves, it is true, such objects give no weight or authority to an oath; it is God Himself who does this, whose divine majesty shines forth in them Hence to swear by the Gospel is to swear by God Himself, whose truth is contained and revealed in the Gospel (This holds equally true with regard to those who swear) by the Saints, who are the temples of God, who believed the truth of His Gospel, were faithful in its observance, and spread it far and wide among the nations and peoples.
This is also true of oaths uttered by way of execration, such as that of St Paul: I call God to witness upon my soul. By this form of oath one submits himself to God's judgment, who is the avenger of falsehood. We do not, however, deny that some of these forms may be used without constituting an oath; but even in such cases it will be found useful to observe what has been said with regard to an oath, and to conform exactly to the same rule and standard.

Oaths Are Affirmatory And Promissory

Oaths are of two kinds. The first is an affirmatory oath, and is taken when we religiously affirm anything, past or present. Such was the affirmation of the Apostle in his Epistle to the Galatians: Behold, before God, I lie not. The second kind, to which comminations may be reduced, is called promissory. It looks to the future, and is taken when we promise and affirm for certain that such or such a thing will be done. Such was the oath of David, who, swearing by the Lord his God, promised to Bethsabee his wife that her son Solomon should be heir to his kingdom and successor to his throne.

Conditions Of A Lawful Oath

Although to constitute an oath it is sufficient to call God to witness, yet to constitute a holy and just oath many other conditions are required, which should be carefully explained. These, as St Jerome observes, are briefly enumerated in the words of Jeremias: Thou shalt swear: as the Lord liveth, in truth and in judgment and in justice, words which briefly sum up all the conditions that constitute the perfection of an oath, namely, truth, judgment, justice.

First Condition: Truth

Truth, then, holds the first place in an oath. What is asserted must be true and he who swears must believe what he swears to be true, being influenced not by rash judgment or mere conjecture, but by solid reasons.
Truth is a condition not less necessary in a promissory than in an affirmatory oath. He who promises must be disposed to perform and fulfil his promise at the appointed time. As no conscientious man will promise to do what he considers opposed to the most holy Commandments and will of God; so, having promised and sworn to do what is lawful, he will never fail to adhere to his engagement, unless, perhaps by a change of circumstances it should happen that, if he wished to keep faith and observe his promises, he must incur the displeasure and enmity of God. That truth is necessary to an oath David also declares in these words: He that sweareth to his neighbour, and deceiveth not.

Second Condition: Judgment

The second condition of an oath is judgment. An oath is not to be taken rashly and inconsiderately, but after deliberation and reflection. When about to take an oath, therefore, one should first consider whether he is obliged to take it, and should weigh well the whole case, reflecting whether it seems to call for an oath. Many other circumstances of time, place, etc., are also to be taken into consideration; and one should not be influenced by love or hatred, or any other passion, but by the nature and necessity of the case.
Unless this careful consideration and reflection precede, an oath must be rash and hasty; and of this character are the irreligious affirmations of those, who, on the most unimportant and trifling occasions, swear without thought or reason from the influence of bad habit alone. This we see practiced daily everywhere among buyers and sellers. The latter, to sell at the highest price, the former to purchase at the cheapest rate, make no scruple to strengthen with an oath their praise or dispraise of the goods on sale.
Since, therefore, judgment and prudence are necessary, and since children are not able, on account of their tender years, to understand and judge accurately, Pope St. Cornelius decreed that an oath should not be administered to children before puberty, that is, before their fourteenth year.

Third Condition: Justice

The last condition (of an oath) is justice, which is especially requisite in promissory oaths. Hence, if a person swear to do what is unjust or unlawful, he sins by taking the oath, and adds sin to sin by executing his promise. Of this the Gospel supplies an example. King Herod, bound by a rash oath, gave to a dancing girl the head of John the Baptist as a reward for her dancing. Such was also the oath taken by the Jews, who, as we read in the Acts of the Apostles, bound themselves by oath not to eat, until they had killed Paul.

Lawfulness Of Oaths

These explanations having been given, there can be no doubt that they who observe the above conditions and who guard their oaths with these qualities as with bulwarks, may swear with a safe conscience.
This is easily established by many proofs. For the law of God, which is pure and holy, commands: Thou shalt fear the Lord thy God, and shalt serve him only, and thou shalt swear by his name. All they, writes David, shall be praised that swear by him.
The Scriptures also inform us that the most holy Apostles, the lights of the Church, sometimes made use of oaths, as appears from the Epistles of the Apostle.
Even the Angels sometimes swear. The angel, writes St. John in the Apocalypse, swore by him who lives for ever.
Nay, God Himself, the Lord of Angels, swears, and, as we read in many passages of the Old Testament, has confirmed His. promises with an oath. This He did to Abraham and to David. Of the oath sworn by God David says: The Lord hath sworn, and he will not repent: thou art a priest for ever according to the order of Melchisedech.
In fact, if we consider the whole matter attentively, and examine the origin and purpose of an oath, it can be no difficult matter to explain the reasons why it is a laudable act.
An oath has its origin in faith, by which men believe God to be the author of all truth, who can never deceive others nor be deceived, to whose eyes all things are naked and open, who, in fine, superintends all human affairs with an admirable providence, and governs the world. Filled with this faith we appeal to God as a witness of the truth, as a witness whom it would be wicked and impious to distrust.
With regard to the end of an oath, its scope and intent is to establish the justice and innocence of man, and to terminate disputes and contests. This is the doctrine of the Apostle in his Epistle to the Hebrews.

An Objection Against Oaths

Nor does this doctrine at all clash with these words of the Redeemer, recorded in St. Matthew: You have heard that it was said to them of old: "Thou shalt not foreswear thyself, but thou shalt perform thy oaths to the Lord"; but I say to you not to swear at all; neither by heaven, for it is the throne of God; neither by the earth, for it is his footstool; nor by Jerusalem, for it is the city of the great king; neither shalt thou swear by thy head, because thou canst not make one hair white or black. But let your speech be "yea, yea"; "no, no"; and that which is over and above these is of evil.
It cannot be asserted that these words condemn oaths universally and under all circumstances, since we have already seen that the Apostles and our Lord Himself made frequent use of them. The object of our Lord was rather to reprove the perverse opinion of the Jews, who had persuaded themselves that the only thing to be avoided in an oath was a lie. Hence in matters the most trivial and unimportant they did not hesitate to make frequent use of oaths, and to exact them from others. This practice the Redeemer condemns and reprobates, and teaches that an oath is never to be taken unless necessity require it. For oaths have been instituted on account of human frailty. They are really the outcome of evil, being a sign either of the inconstancy of him who takes them, or of the obstinacy of him who refuses to believe without them. However, an oath can be justified by necessity.
When our Lord says: Let your speech be "yea, yea"; "no, no," He evidently forbids the habit of swearing in familiar conversation and on trivial matters. He therefore admonishes us particularly against being too ready and willing to swear; and this should be carefully explained and impressed on the minds of the faithful. That countless evils grow out of the unrestrained habit of swearing is proved by the evidence of Scripture, and the testimony of the most holy Fathers. Thus we read in Ecclesiasticus: Let not thy mouth be accustomed to swearing, for in it there are many falls; and again: A man that sweareth much shall be filled with iniquity, and a scourge shall not depart from his house. In the works of St. Basil and St. Augustine against lying, much more can be found on this subject.

Negative Part of this Commandment

So far we have considered what this Commandment requires. It now remains to speak of what it prohibits; namely, to take the name of God in vain. It is clear that he who swears rashly and without deliberation commits a grave sin. That this is a most serious sin is declared by the words: Thou shalt not take the name of thy God in vain, which seem to assign the reason why this crime is so wicked and heinous; namely, that it derogates from the majesty of Him whom we profess to recognise as our Lord and our God. This Commandment, therefore, forbids to swear falsely, because he who does not shrink from so great a crime as to appeal to God to witness falsehood, offers a grievous Injury to God, charging Him either with ignorance, as though the truth of any matter could be unknown to Him, or with malice and dishonesty, as though God could bear testimony to falsehood.

Various Ways In Which God's Name Is Dishonoured: False Oaths

Among false swearers are to be numbered not only those who affirm as true what they know to be false, but also those who swear to what is really true, believing it to be false. For since the essence of a lie consists in speaking contrary to one's belief and conviction, these persons are evidently guilty of a lie, and of perjury.
On the same principle, he who swears to that which he thinks to be true, but which is really false, also incurs the guilt of perjury, unless he has used proper care and diligence to arrive at a full knowledge of the matter. Although he swears according to his belief, he nevertheless sins against this Commandment.
Again, he who binds himself by oath to the performance of anything, not intending to fulfil his promise, or, having had the intention, neglect its performance, guilty of the same sin. This equally applies to those who, having bound themselves to God by vow, neglect its fulfilment.

Unjust Oaths

This Commandment is also violated, if justice, which is one of the three conditions of an oath, be wanting. Hence he who swears to commit a mortal sin, for example, to perpetrate murder, violates this Commandment, even though he speak seriously and from his heart, and his oath possess what we before pointed out as the first condition of every oath, that is, truth.
To these are to be added oaths sworn through a sort of contempt, such as an oath not to observe the Evangelical counsels, such as celibacy and poverty. None, it is true, are obliged to embrace these divine counsels, but by swearing not to observe them, one contemns and despises them.

Rash Oaths

This Commandment is also sinned against, and judgment is violated when one swears to what is true and what he believes to be true if his motives are light conjectures and far­fetched reasons. For, notwithstanding its truth, such an oath is not unmixed with a sort of falsehood, seeing that he who swears with such indifference exposes himself to extreme danger of perjury.

Oaths By False Gods

To swear by false gods is likewise to swear falsely. What more opposed to truth than to appeal to lying and false deities as to the true God?

Irreverent Speech

Scripture when it prohibits perjury, says: Thou shalt not profane the name of thy God, thereby forbidding all irreverence towards all other things to which, in accordance with this Commandment, reverence is due. Of this nature is the Word of God, the majesty of which has been revered not only by the pious, but also sometimes by the impious, as is narrated in Judges of Eglon, King of the Moabites.
But he who, to support heresy and the teaching of the wicked. distorts the Sacred Scriptures from their genuine and true meaning, is guilty of the greatest injury to the Word of God; and against this crime we are warned by these words of the Prince of the Apostles: There are certain things hard to be understood. which the unlearned and unstable wrest, as they do also the other Scriptures, to their own destruction.
It is also a foul and shameful contamination of the Scripture, that wicked men pervert the words and sentences which it contains, and which should be honoured with all reverence, turning them to profane purposes, such as scurrility, fable, vanity, flattery, detraction, divination, satire and the like ­­ crimes which the Council of Trent commands to be severely punished.

Neglect Of Prayer

In the next place, as they honour God who, in their affliction implore His help, so they, who do not invoke His aid, deny Him due honour; and these David rebukes when he says: They have not called upon the Lord, they trembled for fear where there was no fear.

Blasphemy

Still more enormous is the guilt of those who, with impure and defiled lips, dare to curse or blaspheme the holy name of God­that name which is to be blessed and praised above measure by all creatures, or even the names of the Saints who reign with Him in glory.' So atrocious and horrible is this crime that the Sacred Scriptures, sometimes when speaking of blasphemy use the word blessing.

Sanction of this Commandment

As, however, the dread of punishment has often a powerful effect in checking the tendency to sin, the pastor, in order the more effectively to move the minds of men and the more easily to induce to an observance of this Commandment, should diligently explain the remaining words, which are, as it were, its appendix: For the Lord will not hold him guiltless that shall take the name of the Lord his God in vain.
In the first place (the pastor) should teach that with very good reason has God joined threats to this Commandment. From this is understood both the grievousness of sin and the goodness of God toward us, since far from rejoicing in man's destruction, He deters us by these salutary threats from incurring His anger, doubtless in order that we may experience His kindness rather than His wrath. The pastor should urge and insist on this consideration with greatest earnestness. in order that the faithful may be made sensible of the grievousness of the crime, may detest it still more, and may employ increased care and caution to avoid its commission.
He should also observe how prone men are to this sin, since it was not sufficient to give the command, but also necessary to accompany it with threats. The advantages to be derived from this thought are indeed incredible; for as nothing is more injurious than a listless security, so the knowledge of our own weakness is most profitable.
He should next show that God has appointed no particular punishment. The threat is general; it declares that whoever is guilty of this crime shall not escape unpunished. The various chastisements, therefore, with which we are every day visited, should warn us against this sin. It is easy to conjecture that men are afflicted with heavy calamities because they violate this Commandment; and if these things are called to their attention, it is likely that they will be more careful for the future.
Deterred, therefore, by a holy dread, the faithful should use every exertion to avoid this sin. If for every idle word that men shall speak, they shall render an account on the day of judgment, what shall we say of those heinous crimes which involve great contempt of the divine name?
