Summa Theologica by Saint Thomas Aquinas (whitelam books .TXT) 📕

Obj. 2: Further, the more a sin is opposed to virtue the graver it would seem to be. Now irreligion, of which the temptation of God is a species, is more opposed to the virtue of religion, than superstition which bears some likeness to religion. Therefore to tempt God is a graver sin than superstition.

Obj. 3: Further, it seems to be a greater sin to behave disrespectfully to one's parents, than to pay others the respect we owe to our parents. Now God should be honored by us as the Father of all (Malach. 1:6). Therefore, temptation of God whereby we behave irreverently to God, seems to be a greater sin than idolatry, whereby we give to a creature the honor we owe to God.

On the contrary, A gloss on Deut. 17:2, "When there shall be found among you," etc. says: "The Law detests error and idolatry above all: for it is a very great sin to give to a creature the honor that belongs to the Creator."

I answer that, Among sins opposed to religion, the more grievous is that which is the more opposed to the reverence due to God. Now it is less opposed to this reverence that one should doubt the divine excellence than that one should hold the contrary for certain. For just as a man is more of an unbeliever if he be confirmed in his error, than if he doubt the truth of faith, so, too, a man acts more against the reverence due to God, if by his deeds he professes an error contrary to the divine excellence, than if he expresses a doubt. Now the superstitious man professes an error, as shown above (Q. 94, A. 1, ad 1), whereas he who tempts God by words or deeds expresses a doubt of the divine excellence, as stated above (A. 2). Therefore the sin of superstition is graver than the sin of tempting God.

Reply Obj. 1: The sin of idolatry was not punished in the above manner, as though it were a sufficient punishment; because a more severe punishment was reserved in the future for that sin, for it is written (Ex. 32:34): "And I, in the day of revenge, will visit this sin also of theirs."

Reply Obj. 2: Superstition bears a likeness to religion, as regards the material act which it pays just as religion does. But, as regards the end, it is more contrary to religion than the temptation of God, since it implies greater irreverence for God, as stated.

Reply Obj. 3: It belongs essentially to the divine excellence that it is singular and incommunicable. Consequently to give divine reverence to another is the same as to do a thing opposed to the divine excellence. There is no comparison with the honor due to our parents, which can without sin be given to others. _______________________

OF PERJURY
(In Four Articles)

We must now consider perjury: under which head there are four points of inquiry:

(1) Whether falsehood is necessary for perjury?

(2) Whether perjury is always a sin?

(3) Whether it is always a mortal sin?

(4) Whether it is a sin to enjoin an oath on a perjurer? _______________________

FIRST ARTICLE [II-II, Q. 98, Art. 1]

Whether It Is Necessary for Perjury That the Statement Confirmed on
Oath Be False?

Objection 1: It would seem that it is not necessary for perjury that the statement confirmed on oath be false. As stated above (Q. 89, A. 3), an oath should be accompanied by judgment and justice no less than by truth. Since therefore perjury is incurred through lack of truth, it is incurred likewise through lack of judgment, as when one swears indiscreetly, and through lack of justice, as when one swears to something unjust.

Obj. 2: Further, that which confirms is more weighty than the thing confirmed thereby: thus in a syllogism the premises are more weighty than the conclusion. Now in an oath a man's statement is confirmed by calling on the name of God. Therefore perjury seems to consist in swearing by false gods rather than in a lack of truth in the human statement which is confirmed on oath.

Obj. 3: Further, Augustine says (De Verb. Apost. Jacobi; Serm. clxxx): "Men swear falsely both in deceiving others and when they are deceived themselves"; and he gives three examples. The first is: "Supposing a man to swear, thinking that what he swears to is true, whereas it is false"; the second is: "Take the instance of another who knows the statement to be false, and swears to it as though it were true"; and the third is: "Take another, who thinks his statement false, and swears to its being true, while perhaps it is true," of whom he says afterwards that he is a perjurer. Therefore one may be a perjurer while swearing to the truth. Therefore falsehood is not necessary for perjury.

On the contrary, Perjury is defined "a falsehood confirmed by oath" [*Hugh of St. Victor, Sum. Sent. iv, 5].

I answer that, As stated above (Q. 92, A. 2), moral acts take their species from their end. Now the end of an oath is the confirmation of a human assertion. To this confirmation falsehood is opposed: since an assertion is confirmed by being firmly shown to be true; and this cannot happen to that which is false. Hence falsehood directly annuls the end of an oath: and for this reason, that perversity in swearing, which is called perjury, takes its species chiefly from falsehood. Consequently falsehood is essential to perjury.

Reply Obj. 1: As Jerome says on Jer. 4:2, "whichever of these three be lacking, there is perjury," but in different order. For first and chiefly perjury consists in a lack of truth, for the reason stated in the Article. Secondly, there is perjury when justice is lacking, for in whatever way a man swears to that which is unlawful, for this very reason he is guilty of falsehood, since he is under an obligation to do the contrary. Thirdly, there is perjury when judgment is lacking, since by the very fact that a man swears indiscreetly, he incurs the danger of lapsing into falsehood.

Reply Obj. 2: In syllogisms the premises are of greater weight, since they are in the position of active principle, as stated in Phys. ii, 3: whereas in moral matters the end is of greater importance than the active principle. Hence though it is a perverse oath when a man swears to the truth by false gods, yet perjury takes its name from that kind of perversity in an oath, that deprives the oath of its end, by swearing what is false.

Reply Obj. 3: Moral acts proceed from the will, whose object is the apprehended good. Wherefore if the false be apprehended as true, it will be materially false, but formally true, as related to the will. If something false be apprehended as false, it will be false both materially and formally. If that which is true be apprehended as false, it will be materially true, and formally false. Hence in each of these cases the conditions required for perjury are to be found in some way, on account of some measure of falsehood. Since, however, that which is formal in anything is of greater importance than that which is material, he that swears to a falsehood thinking it true is not so much of a perjurer as he that swears to the truth thinking it false. For Augustine says (De Verb. Apost. Jacobi; Serm. clxxx): "It depends how the assertion proceeds from the mind, for the tongue is not guilty except the mind be guilty." _______________________

SECOND ARTICLE [II-II, Q. 98, Art. 2]

Whether All Perjury Is Sinful?

Objection 1: It would seem that not all perjury is sinful. Whoever does not fulfil what he has confirmed on oath is seemingly a perjurer. Yet sometimes a man swears he will do something unlawful (adultery, for instance, or murder): and if he does it, he commits a sin. If therefore he would commit a sin even if he did it not, it would follow that he is perplexed.

Obj. 2: Further, no man sins by doing what is best. Yet sometimes by committing a perjury one does what is best: as when a man swears not to enter religion, or not to do some kind of virtuous deed. Therefore not all perjury is sinful.

Obj. 3: Further, he that swears to do another's will would seem to be guilty of perjury unless he do it. Yet it may happen sometimes that he sins not, if he do not the man's will: for instance, if the latter order him to do something too hard and unbearable. Therefore seemingly not all perjury is sinful.

Obj. 4: Further, a promissory oath extends to future, just as a declaratory oath extends to past and present things. Now the obligation of an oath may be removed by some future occurrence: thus a state may swear to fulfil some obligation, and afterwards other citizens come on the scene who did not take the oath; or a canon may swear to keep the statutes of a certain church, and afterwards new statutes are made. Therefore seemingly he that breaks an oath does not sin.

On the contrary, Augustine says (De Verb. Apost. Jacobi; Serm. cxxx), in speaking of perjury: "See how you should detest this horrible beast and exterminate it from all human business."

I answer that, As stated above (Q. 89, A. 1), to swear is to call God as witness. Now it is an irreverence to God to call Him to witness to a falsehood, because by so doing one implies either that God ignores the truth or that He is willing to bear witness to a falsehood. Therefore perjury is manifestly a sin opposed to religion, to which it belongs to show reverence to God.

Reply Obj. 1: He that swears to do what is unlawful is thereby guilty of perjury through lack of justice: though, if he fails to keep his oath, he is not guilty of perjury in this respect, since that which he swore to do was not a fit matter of an oath.

Reply Obj. 2: A person who swears not to enter religion, or not to give an alms, or the like, is guilty of perjury through lack of judgment. Hence when he does that which is best it is not an act of perjury, but contrary thereto: for the contrary of that which he is doing could not be a matter of an oath.

Reply Obj. 3: When one man swears or promises to do another's will, there is to be understood this requisite condition—that the thing commanded be lawful and virtuous, and not unbearable or immoderate.

Reply Obj. 4: An oath is a personal act, and so when a man becomes a citizen of a state, he is not bound, as by oath, to fulfil whatever the state has sworn to do. Yet he is bound by a kind of fidelity, the nature of which obligation is that he should take his share of the state's burdens if he takes a share of its goods.

The canon who swears to keep the statutes that have force in some particular "college" is not bound by his oath to keep any that may be made in the future, unless he intends to bind himself to keep all, past and future. Nevertheless he is bound to keep them by virtue of the statutes themselves, since they are possessed of coercive force, as stated above (I-II, Q. 96, A. 4). _______________________

THIRD ARTICLE [II-II, Q. 98, Art. 3]

Whether All Perjury Is a Mortal Sin?

Objection 1: It would seem that not all perjury is a mortal sin. It is laid down (Extra, De Jurejur., cap. Verum): "Referring to the question whether an oath is binding on those who have taken one in order to safeguard their life and possessions, we have no other mind than that which our predecessors the Roman Pontiffs are known to have had, and who absolved such persons from the obligations of their oath. Henceforth, that discretion may be observed, and in order to avoid occasions of perjury, let them not be told expressly not to keep their oath: but if they should not keep it, they are not for this reason to be punished as for a mortal sin." Therefore not all perjury is a mortal sin.

Obj. 2. Further, as Chrysostom [*Hom. xliv in the Opus Imperfectum on St. Matthew, falsely ascribed to St. John Chrysostom] says, "it is a greater thing to swear by God than by the Gospels." Now it is not always a mortal sin to swear by God to something false; for instance, if
