Summa Th. II-II EN Qu.70 a.2
Objection: 1. It would seem that the evidence of two or three persons is not sufficient. For judgment requires certitude. Now certitude of the truth is not obtained by the assertions of two or three witnesses, for we read that Naboth was unjustly condemned on the evidence of two witnesses (1R 21). Therefore the evidence of two or three witnesses does not suffice.
2. Further, in order for evidence to be credible it must agree. But frequently the evidence of two or three disagrees in some point. Therefore it is of no use for proving the truth in court.
3. Further, it is laid down (Decret. II, qu. iv, can. Praesul.): "A bishop shall not be condemned save on the evidence of seventy-two witnesses; nor a cardinal priest of the Roman Church, unless there be sixty-four witnesses. Nor a cardinal deacon of the Roman Church, unless there be twenty-seven witnesses; nor a subdeacon, an acolyte, an exorcist, a reader or a doorkeeper without seven witnesses." Now the sin of one who is of higher dignity is more grievous, and consequently should be treated more severely. Therefore neither is the evidence of two or three witnesses sufficient for the condemnation of other persons.
On the contrary It is written (Dt 17,6): "By the mouth of two or three witnesses shall he die that is to be slain," and further on (Dt 19,15): "In the mouth of two or three witnesses every word shall stand."
I answer that According to the Philosopher (Ethic. i, 3), "we must not expect to find certitude equally in every matter." For in human acts, on which judgments are passed and evidence required, it is impossible to have demonstrative certitude, because they a about things contingent and variable. Hence the certitude of probability suffices, such as may reach the truth in the greater number, cases, although it fail in the minority. No it is probable that the assertion of sever witnesses contains the truth rather than the assertion of one: and since the accused is the only one who denies, while several witness affirm the same as the prosecutor, it is reasonably established both by Divine and by human law, that the assertion of several witnesses should be upheld. Now all multitude is comprised of three elements, the beginning, the middle and the end. Wherefore, according to the Philosopher (De Coelo i, 1), "we reckon 'all' and 'whole' to consist of three parts." Now we have a triple voucher when two agree with the prosecutor: hence two witnesses are required; or for the sake of greater certitude three, which is the perfect number. Wherefore it is written (Qo 4,12): "A threefold cord is not easily broken": and Augustine, commenting on Jn 8,17, "The testimony of two men is true," says (Tract. xxxvi) that "there is here a mystery by which we are given to understand that Trinity wherein is perpetual stability of truth."
Reply to Objection: 1. No matter how great a number of witnesses may be determined, the evidence might sometimes be unjust, since is written (Ex 23,2): "Thou shalt not follow the multitude to do evil." And yet the fact that in so many it is not possible to have certitude without fear of error, is no reason why we should reject the certitude which can probably be had through two or three witnesses, as stated above.
2. If the witnesses disagree certain principal circumstances which change the substance of the fact, for instance in time, place, or persons, which are chiefly in question, their evidence is of no weight, because if they disagree in such things, each one would seem to be giving distinct evidence and to be speaking of different facts. For instance, one say that a certain thing happened at such and such a time or place, while another says it happened at another time or place, they seem not to be speaking of the same event. The evidence is not weakened if one witness says that he does not remember, while the other attests to a determinate time or place And if on such points as these the witness for prosecution and defense disagree altogether, and if they be equal in number on either side, and of equal standing, the accused should have the benefit of the doubt, because the judge ought to be more inclined to acquit than to condemn, except perhaps in favorable suits, such as a pleading for liberty and the like. If, however, the witnesses for the same side disagree, the judge ought to use his own discretion in discerning which side to favor, by considering either the number of witnesses, or their standing, or the favorableness of the suit, or the nature of the business and of the evidenceMuch more ought the evidence of one witness to be rejected if he contradict himself when questioned about what he has seen and about what he knows; not, however, if he contradict himself when questioned about matters of opinion and report, since he may be moved to answer differently according to the different things he has seen and heard.On the other hand if there be discrepancy of evidence in circumstances not touching the substance of the fact, for instance, whether the weather were cloudy or fine, whether the house were painted or not, or such like matters, such discrepancy does not weaken the evidence, because men are not wont to take much notice of such things, wherefore they easily forget them. Indeed, a discrepancy of this kind renders the evidence more credible, as Chrysostom states (Hom. i in Matth.), because if the witnesses agreed in every point, even in the minutest of details, they would seem to have conspired together to say the same thing: but this must be left to the prudent discernment of the judge.
3. This passage refers specially to the bishops, priests, deacons and clerics of the Roman Church, on account of its dignity: and this for three reasons. First because in that Church those men ought to be promoted whose sanctity makes their evidence of more weight than that of many witnesses. Secondly, because those who have to judge other men, often have many opponents on account of their justice, wherefore those who give evidence against them should not be believed indiscriminately, unless they be very numerous. Thirdly, because the condemnation of any one of them would detract in public opinion from the dignity and authority of that Church, a result which would be more fraught with danger than if one were to tolerate a sinner in that same Church, unless he were very notorious and manifest, so that a grave scandal would arise if he were tolerated.
Objection: 1. It would seem that a man's evidence ought not to be rejected except on account of some fault. For it a penalty on some that their evidence is inadmissible, as in the case of those who are branded with infamy. Now a penalty must not be inflicted save for a fault. Therefore it would seem that no man's evidence ought to be rejected save on account of a fault.
2. Further, "Good is to be presumed of every one, unless the contrary appear" [*Cap. Dudum, de Praesumpt.]. Now it pertains to a man's goodness that he should give true evidence. Since therefore there can be no proof of the contrary, unless there be some fault of his, it would seem that no man's evidence should be rejected save for some fault.
3. Further, no man is rendered unfit for things necessary for salvation except by some sin. But it is necessary for salvation to give true evidence, as stated above (Article [1]). Therefore no man should be excluded from giving evidence save for some fault.
On the contrary Gregory says (Regist. xiii, 44): "As to the bishop who is said to have been accused by his servants, you are to know that they should by no means have been heard": which words are embodied in the Decretals II, qu. 1, can. Imprimis.
I answer that As stated above (Article [2]), the authority of evidence is not infallible but probable; and consequently the evidence for one side is weakened by whatever strengthens the probability of the other. Now the reliability of a person's evidence is weakened, sometimes indeed on account of some fault of his, as in the case of unbelievers and persons of evil repute, as well as those who are guilty of a public crime and who are not allowed even to accuse; sometimes, without any fault on his part, and this owing either to a defect in the reason, as in the case of children, imbeciles and women, or to personal feeling, as in the case of enemies, or persons united by family or household ties, or again owing to some external condition, as in the case of poor people, slaves, and those who are under authority, concerning whom it is to be presumed that they might easily be induced to give evidence against the truth.Thus it is manifest that a person's evidence may be rejected either with or without some fault of his.
Reply to Objection: 1. If a person is disqualified from giving evidence this is done as a precaution against false evidence rather than as a punishment. Hence the argument does not prove.
2. Good is to be presumed of everyone unless the contrary appear, provided this does not threaten injury to another: because, in that case, one ought to be careful not to believe everyone readily, according to 1Jn 4,1: "Believe not every spirit."
3. To give evidence is necessary for salvation, provided the witness be competent, and the order of justice observed. Hence nothing hinders certain persons being excused from giving evidence, if they be considered unfit according to law.
Objection: 1. It would seem that it is not always a mortal sin to give false evidence. For a person may happen to give false evidence, through ignorance of fact. Now such ignorance excuses from mortal sin. Therefore the giving of false evidence is not always a mortal sin.
2. Further, a lie that benefits someone and hurts no man is officious, and this is not a mortal sin. Now sometimes a lie of this kind occurs in false evidence, as when a person gives false evidence in order to save a man from death, or from an unjust sentence which threatens him through other false witnesses or a perverse judge. Therefore in such cases it is not a mortal sin to give false evidence.
3. Further, a witness is required to take an oath in order that he may fear to commit a mortal sin of perjury. But this would not be necessary, if it were already a mortal sin to give false evidence. Therefore the giving of false evidence is not always mortal sin.
On the contrary It is written (Pr 19,5): "A false witness shall not be unpunished."
I answer that False evidence has a threefold deformity. The first is owing to perjury, since witnesses are admitted only on oath and on this count it is always a mortal sin. Secondly, owing to the violation of justice, and on this account it is a mortal sin generically, even as any kind of injustice. Hence the prohibition of false evidence by the precept of the decalogue is expressed in this form when it is said (Ex 20,16), "Thou shalt not bear false witness against thy neighbor." For one does nothing against a man by preventing him from doing someone an injury, but only by taking away his justice. Thirdly, owing to the falsehood itself, by reason of which every lie is a sin: on this account, the giving of false evidence is not always a mortal sin.
Reply to Objection: 1. In giving evidence a man ought not to affirm as certain, as though he knew it, that about which he is not certain and he should confess his doubt in doubtful terms, and that which he is certain about, in terms of certainty. Owing however to the frailty of the human memory, a man sometimes thinks he is certain about something that is not true; and then if after thinking over the matter with due care he deems himself certain about that false thing, he does not sin mortally if he asserts it, because the evidence which he gives is not directly an intentionally, but accidentally contrary to what he intends.
2. An unjust judgment is not a judgment, wherefore the false evidence given in an unjust judgment, in order to prevent injustice is not a mortal sin by virtue of the judgment, but only by reason of the oath violated.
3. Men abhor chiefly those sin that are against God, as being most grievous and among them is perjury: whereas they do not abhor so much sins against their neighbor. Consequently, for the greater certitude of evidence, the witness is required to take a oath.
We must now consider the injustice which takes place in judgment on the part of counsel, and under this head there are four points of inquiry:
(1) Whether an advocate is bound to defend the suits of the poor?
(2) Whether certain persons should be prohibited from exercising the office of advocate?
(3) Whether an advocate sins by defending an unjust cause?
(4) Whether he sins if he accept a fee for defending a suit?
Objection: 1. It would seem that an advocate is bound to defend the suits of the poor. For it is written (Ex 23,5): "If thou see the ass of him that hateth thee lie underneath his burden, thou shalt not pass by, but shall lift him up with him." Now no less a danger threatens the poor man whose suit is being unjustly prejudiced, than if his ass were to lie underneath its burden. Therefore an advocate is bound to defend the suits of the poor.
2. Further, Gregory says in a homily (ix in Evang.): "Let him that hath understanding beware lest he withhold his knowledge; let him that hath abundance of wealth watch lest he slacken his merciful bounty; let him who is a servant to art share his skill with his neighbor; let him who has an opportunity of speaking with the wealthy plead the cause of the poor: for the slightest gift you have received will be reputed a talent." Now every man is bound, not to hide but faithfully to dispense the talent committed to him; as evidenced by the punishment inflicted on the servant who hid his talent (Mt 25,30). Therefore an advocate is bound to plead for the poor.
3. Further, the precept about performing works of mercy, being affirmative, is binding according to time and place, and this is chiefly in cases of need. Now it seems to be a case of need when the suit of a poor man is being prejudiced. Therefore it seems that in such a case an advocate is bound to defend the poor man's suit.
On the contrary He that lacks food is no less in need than he that lacks an advocate. Yet he that is able to give food is not always bound to feed the needy. Therefore neither is an advocate always bound to defend the suits of the poor.
I answer that Since defense of the poor man's suit belongs to the works of mercy, the answer to this inquiry is the same as the one given above with regard to the other works of mercy (Question [32], Articles [5],9). Now no man is sufficient to bestow a work of mercy on all those who need it. Wherefore, as Augustine says (De Doctr. Christ. i, 28), "since one cannot do good to all, we ought to consider those chiefly who by reason of place, time, or any other circumstance, by a kind of chance are more closely united to us." He says "by reason of place," because one is not bound to search throughout the world for the needy that one may succor them; and it suffices to do works of mercy to those one meets with. Hence it is written (Ex 23,4): "If thou meet thy enemy's ass going astray, bring it back to him." He says also "by reason of time," because one is not bound to provide for the future needs of others, and it suffices to succor present needs. Hence it is written (1Jn 3,17): "He that . . . shall see his brother in need, and shall put up his bowels from him, how doth the charity of God abide in him?" Lastly he says, "or any other circumstance," because one ought to show kindness to those especially who are by any tie whatever united to us, according to 1Tm 5,8, "If any man have not care of his own, and especially of those of his house, he hath denied the faith and is worse than an infidel."It may happen however that these circumstances concur, and then we have to consider whether this particular man stands in such a need that it is not easy to see how he can be succored otherwise, and then one is bound to bestow the work of mercy on him. If, however, it is easy to see how he can be otherwise succored, either by himself, or by some other person still more closely united to him, or in a better position to help him, one is not bound so strictly to help the one in need that it would be a sin not to do so: although it would be praiseworthy to do so where one is not bound to. Therefore an advocate is not always bound to defend the suits of the poor, but only when the aforesaid circumstances concur, else he would have to put aside all other business, and occupy himself entirely in defending the suits of poor people. The same applies to a physician with regard to attendance on the sick.
Reply to Objection: 1. So long as the ass lies under the burden, there is no means of help in this case, unless those who are passing along come to the man's aid, and therefore they are bound to help. But they would not be so bound if help were possible from another quarter.
2. A man is bound to make good use of the talent bestowed on him, according to the opportunities afforded by time, place, and other circumstances, as stated above.
3. Not every need is such that it is one's duty to remedy it, but only such as we have stated above.
Objection: 1. It would seem unfitting for the law to debar certain persons from the office of advocate. For no man should be debarred from doing works of mercy. Now it belongs to the works of mercy to defend a man's suit, as stated above (Article [1]). Therefore no man should be debarred from this office.
2. Further, contrary causes have not, seemingly, the same effect. Now to be busy with Divine things and to be busy about sin are contrary to one another. Therefore it is unfitting that some should be debarred from the office of advocate, on account of religion, as monks and clerics, while others are debarred on account of sin, as persons of ill-repute and heretics.
3. Further, a man should love his neighbor as himself. Now it is a duty of love for an advocate to plead a person's cause. Therefore it is unfitting that certain persons should be debarred from pleading the cause of others, while they are allowed to advocate their own cause.
On the contrary According to Decretals III, qu. vii, can. Infames, many persons are debarred from the office of advocate.
I answer that In two ways a person is debarred from performing a certain act: first because it is impossible to him, secondly because it is unbecoming to him: but, whereas the man to whom a certain act is impossible, is absolutely debarred from performing it, he to whom an act is unbecoming is not debarred altogether, since necessity may do away with its unbecomingness. Accordingly some are debarred from the office of advocate because it is impossible to them through lack of sense---either interior, as in the case of madmen and minors---or exterior, as in the case of the deaf and dumb. For an advocate needs to have both interior skill so that he may be able to prove the justice of the cause he defends, and also speech and hearing, that he may speak and hear what is said to him. Consequently those who are defective in these points, are altogether debarred from being advocates either in their own or in another's cause. The becomingness of exercising this office is removed in two ways. First, through a man being engaged in higher things. Wherefore it is unfitting that monks or priests should be advocates in any cause whatever, or that clerics should plead in a secular court, because such persons are engaged in Divine things. Secondly, on account of some personal defect, either of body (for instance a blind man whose attendance in a court of justice would be unbecoming) or of soul, for it ill becomes one who has disdained to be just himself, to plead for the justice of another. Wherefore it is unbecoming that persons of ill repute, unbelievers, and those who have been convicted of grievous crimes should be advocates. Nevertheless this unbecomingness is outweighed by necessity: and for this reason such persons can plead either their own cause or that of persons closely connected with them. Moreover, clerics can be advocates in the cause of their own church, and monks in the cause of their own monastery, if the abbot direct them to do so.
Reply to Objection: 1. Certain persons are sometimes debarred by unbecomingness, and others by inability from performing works of mercy: for not all the works of mercy are becoming to all persons: thus it ill becomes a fool to give counsel, or the ignorant to teach.
2. Just as virtue is destroyed by "too much" and "too little," so does a person become incompetent by "more" and "less." For this reason some, like religious and clerics, are debarred from pleading in causes, because they are above such an office; and others because they are less than competent to exercise it, such as persons of ill-repute and unbelievers.
3. The necessity of pleading the causes of others is not so pressing as the necessity of pleading one's own cause, because others are able to help themselves otherwise: hence the comparison fails.
Objection: 1. It would seem that an advocate does not sin by defending an unjust cause. For just as a physician proves his skill by healing a desperate disease, so does an advocate prove his skill, if he can defend an unjust cause. Now a physician is praised if he heals a desperate malady. Therefore an advocate also commits no sin, but ought to be praised, if he defends an unjust cause.
2. Further, it is always lawful to desist from committing a sin. Yet an advocate is punished if he throws up his brief (Decret. II, qu. iii, can. Si quem poenit.). Therefore an advocate does not sin by defending an unjust cause, when once he has undertaken its defense.
3. Further, it would seem to be a greater sin for an advocate to use unjust means in defense of a just cause (e.g. by producing false witnesses, or alleging false laws), than to defend an unjust cause, since the former is a sin against the form, the latter against the matter of justice. Yet it is seemingly lawful for an advocate to make use of such underhand means, even as it is lawful for a soldier to lay ambushes in a battle. Therefore it would seem that an advocate does not sin by defending an unjust cause.
On the contrary It is said (2Ch 19,2): "Thou helpest the ungodly . . . and therefore thou didst deserve . . . the wrath of the Lord." Now an advocate by defending an unjust cause, helps the ungodly. Therefore he sins and deserves the wrath of the Lord.
I answer that It is unlawful to cooperate in an evil deed, by counseling, helping, or in any way consenting, because to counsel or assist an action is, in a way, to do it, and the Apostle says (Rm 1,32) that "they . . . are worthy of death, not only they that do" a sin, "but they also that consent to them that do" it. Hence it was stated above (Question [62], Article [7]), that all such are bound to restitution. Now it is evident that an advocate provides both assistance and counsel to the party for whom he pleads. Wherefore, if knowingly he defends an unjust cause, without doubt he sins grievously, and is bound to restitution of the loss unjustly incurred by the other party by reason of the assistance he has provided. If, however, he defends an unjust cause unknowingly, thinking it just, he is to be excused according to the measure in which ignorance is excusable.
Reply to Objection: 1. The physician injures no man by undertaking to heal a desperate malady, whereas the advocate who accepts service in an unjust cause, unjustly injures the party against whom he pleads unjustly. Hence the comparison fails. For though he may seem to deserve praise for showing skill in his art, nevertheless he sins by reason of injustice in his will, since he abuses his art for an evil end.
2. If an advocate believes from the outset that the cause is just, and discovers afterwards while the case is proceeding that it is unjust, he ought not to throw up his brief in such a way as to help the other side, or so as to reveal the secrets of his client to the other party. But he can and must give up the case, or induce his client to give way, or make some compromise without prejudice to the opposing party.
3. As stated above (Question [40], Article [3]), it is lawful for a soldier, or a general to lay ambushes in a just war, by prudently concealing what he has a mind to do, but not by means of fraudulent falsehoods, since we should keep faith even with a foe, as Tully says (De offic. iii, 29). Hence it is lawful for an advocate, in defending his case, prudently to conceal whatever might hinder its happy issue, but it is unlawful for him to employ any kind of falsehood.
Objection: 1. It would seem unlawful for an advocate to take a fee for pleading. Works of mercy should not be done with a view to human remuneration, according to Lc 14,12, "When thou makest a dinner or a supper, call not thy friends . . . nor thy neighbors who are rich: lest perhaps they also invite thee again, and a recompense be made to thee." Now it is a work of mercy to plead another's cause, as stated above (Article [1]). Therefore it is not lawful for an advocate to take payment in money for pleading.
2. Further, spiritual things are not to be bartered with temporal things. But pleading a person's cause seems to be a spiritual good since it consists in using one's knowledge of law. Therefore it is not lawful for an advocate to take a fee for pleading.
3. Further, just as the person of the advocate concurs towards the pronouncement of the verdict, so do the persons of the judge and of the witness. Now, according to Augustine (Ep. cliii ad Macedon.), "the judge should not sell a just sentence, nor the witness true evidence." Therefore neither can an advocate sell a just pleading.
On the contrary Augustine says (Ep. cliii ad Macedon.) that "an advocate may lawfully sell his pleading, and a lawyer his advice."
I answer that A man may justly receive payment for granting what he is not bound to grant. Now it is evident that an advocate is not always bound to consent to plead, or to give advice in other people's causes. Wherefore, if he sell his pleading or advice, he does not act against justice. The same applies to the physician who attends on a sick person to heal him, and to all like persons; provided, however, they take a moderate fee, with due consideration for persons, for the matter in hand, for the labor entailed, and for the custom of the country. If, however, they wickedly extort an immoderate fee, they sin against justice. Hence Augustine says (Ep. cliii ad Macedon.) that "it is customary to demand from them restitution of what they have extorted by a wicked excess, but not what has been given to them in accordance with a commendable custom."
Reply to Objection: 1. Man is not bound to do gratuitously whatever he can do from motives of mercy: else no man could lawfully sell anything, since anything may be given from motives of mercy. But when a man does give a thing out of mercy, he should seek, not a human, but a Divine reward. In like manner an advocate, when he mercifully pleads the cause of a poor man, should have in view not a human but a Divine meed; and yet he is not always bound to give his services gratuitously.
2. Though knowledge of law is something spiritual, the use of that knowledge is accomplished by the work of the body: hence it is lawful to take money in payment of that use, else no craftsman would be allowed to make profit by his art.
3. The judge and witnesses are common to either party, since the judge is bound to pronounce a just verdict, and the witness to give true evidence. Now justice and truth do not incline to one side rather than to the other: and consequently judges receive out of the public funds a fixed pay for their labor; and witnesses receive their expenses (not as payment for giving evidence, but as a fee for their labor) either from both parties or from the party by whom they are adduced, because no man "serveth as a soldier at any time at his own charge [*Vulg.: 'Who serveth as a soldier,']" (1Co 9,7). On the other hand an advocate defends one party only, and so he may lawfully accept fee from the party he assists.
We must now consider injuries inflicted by words uttered extrajudicially. We shall consider (1) reviling, (2) backbiting, (3) tale bearing, (4) derision, (5) cursing.
Under the first head there are four points of inquiry:
(1) What is reviling?
(2) Whether every reviling is a mortal sin?
(3) Whether one ought to check revilers?
(4) Of the origin of reviling.
Objection: 1. It would seem that reviling does not consist in words. Reviling implies some injury inflicted on one's neighbor, since it is a kind of injustice. But words seem to inflict no injury on one's neighbor, either in his person, or in his belongings. Therefore reviling does not consist in words.
2. Further, reviling seems to imply dishonor. But a man can be dishonored or slighted by deeds more than by words. Therefore it seems that reviling consists, not in words but in deeds.
3. Further, a dishonor inflicted by words is called a railing or a taunt. But reviling seems to differ from railing or taunt. Therefore reviling does not consist in words.
On the contrary Nothing, save words, is perceived by the hearing. Now reviling is perceived by the hearing according to Jr 20,10, "I heard reviling [Douay: 'contumelies'] on every side." Therefore reviling consists in words.
I answer that Reviling denotes the dishonoring of a person, and this happens in two ways: for since honor results from excellence, one person dishonors another, first, by depriving him of the excellence for which he is honored. This is done by sins of deed, whereof we have spoken above (Question [64], seqq.). Secondly, when a man publishes something against another's honor, thus bringing it to the knowledge of the latter and of other men. This reviling properly so called, and is done I some kind of signs. Now, according to Augustine (De Doctr. Christ. ii, 3), "compared with words all other signs are very few, for words have obtained the chief place among men for the purpose of expressing whatever the mind conceives." Hence reviling, properly speaking consists in words: wherefore, Isidore says (Etym. x) that a reviler [contumeliosus] "is hasty and bursts out [tumet] in injurious words." Since, however, things are also signified by deeds, which on this account have the same significance as words, it follows that reviling in a wider sense extends also to deeds. Wherefore a gloss on Rm 1,30, "contumelious, proud," says: "The contumelious are those who by word or deed revile and shame others."
Reply to Objection: 1. Our words, if we consider them in their essence, i.e. as audible sound injure no man, except perhaps by jarring of the ear, as when a person speaks too loud. But, considered as signs conveying something to the knowledge of others, they may do many kinds of harm. Such is the harm done to a man to the detriment of his honor, or of the respect due to him from others. Hence the reviling is greater if one man reproach another in the presence of many: and yet there may still be reviling if he reproach him by himself. in so far as the speaker acts unjustly against the respect due to the hearer.
2. One man slights another by deeds in so far as such deeds cause or signify that which is against that other man's honor. In the former case it is not a matter of reviling but of some other kind of injustice, of which we have spoken above (Questions [64],65,66): where as in the latter case there is reviling, in so far as deeds have the significant force of words.
3. Railing and taunts consist in words, even as reviling, because by all of them a man's faults are exposed to the detriment of his honor. Such faults are of three kinds. First, there is the fault of guilt, which is exposed by "reviling" words. Secondly, there is the fault of both guilt and punishment, which is exposed by "taunts" [convicium], because "vice" is commonly spoken of in connection with not only the soul but also the body. Hence if one man says spitefully to another that he is blind, he taunts but does not revile him: whereas if one man calls another a thief, he not only taunts but also reviles him. Thirdly, a man reproaches another for his inferiority or indigence, so as to lessen the honor due to him for any kind of excellence. This is done by "upbraiding" words, and properly speaking, occurs when one spitefully reminds a man that one has succored him when he was in need. Hence it is written (Si 20,15): "He will give a few things and upbraid much." Nevertheless these terms are sometimes employed one for the other.
Summa Th. II-II EN Qu.70 a.2
