Summa Th. II-II EN Qu.33 a.6

Whether one ought to forbear from correcting someone, through fear lest he become worse?

Objection: 1. It would seem that one ought not to forbear from correcting someone through fear lest he become worse. For sin is weakness of the soul, according to Ps 6,3: "Have mercy on me, O Lord, for I am weak." Now he that has charge of a sick person, must not cease to take care of him, even if he be fractious or contemptuous, because then the danger is greater, as in the case of madmen. Much more, therefore should one correct a sinner, no matter how badly he takes it.
2. Further, according to Jerome vital truths are not to be foregone on account of scandal. Now God's commandments are vital truths. Since, therefore, fraternal correction is a matter of precept, as stated above (Article [2]), it seems that it should not be foregone for fear of scandalizing the person to be corrected.
3. Further, according to the Apostle (Rm 3,8) we should not do evil that good may come of it. Therefore, in like manner, good should not be omitted lest evil befall. Now fraternal correction is a good thing. Therefore it should not be omitted for fear lest the person corrected become worse.

On the contrary It is written (Pr 9,8): "Rebuke not a scorner lest he hate thee," where a gloss remarks: "You must not fear lest the scorner insult you when you rebuke him: rather should you bear in mind that by making him hate you, you may make him worse." Therefore one ought to forego fraternal correction, when we fear lest we may make a man worse.
I answer that As stated above (Article [3]) the correction of the wrongdoer is twofold. One, which belongs to prelates, and is directed to the common good, has coercive force. Such correction should not be omitted lest the person corrected be disturbed, both because if he is unwilling to amend his ways of his own accord, he should be made to cease sinning by being punished, and because, if he be incorrigible, the common good is safeguarded in this way, since the order of justice is observed, and others are deterred by one being made an example of. Hence a judge does not desist from pronouncing sentence of condemnation against a sinner, for fear of disturbing him or his friends.The other fraternal correction is directed to the amendment of the wrongdoer, whom it does not coerce, but merely admonishes. Consequently when it is deemed probable that the sinner will not take the warning, and will become worse, such fraternal correction should be foregone, because the means should be regulated according to the requirements of the end.

Reply to Objection: 1. The doctor uses force towards a madman, who is unwilling to submit to his treatment; and this may be compared with the correction administered by prelates, which has coercive power, but not with simple fraternal correction.
2. Fraternal correction is a matter of precept, in so far as it is an act of virtue, and it will be a virtuous act in so far as it is proportionate to the end. Consequently whenever it is a hindrance to the end, for instance when a man becomes worse through it, it is longer a vital truth, nor is it a matter precept.
3. Whatever is directed to end, becomes good through being directed to the end. Hence whenever fraternal correction hinders the end, namely the amendment of our brother, it is no longer good, so that when such a correction is omitted, good is not omitted lest evil should befall.

Whether the precept of fraternal correction demands that a private admonition should precede denunciation?

Objection: 1. It would seem that the precept of fraternal correction does not demand that a private admonition should precede denunciation. For, in works of charity, we should above all follow the example of God, according to Ep 5,1-2: "Be ye followers of God, as most dear children, and walk in love." Now God sometimes punishes a man for a sin, without previously warning him in secret. Therefore it seems that there is no need for a private admonition to precede denunciation.
2. Further, according to Augustine (De Mendacio xv), we learn from the deeds of holy men how we ought to understand the commandments of Holy Writ. Now among the deeds of holy men we find that a hidden sin is publicly denounced, without any previous admonition in private. Thus we read (Gn 37,2) that "Joseph accused his brethren to his father of a most wicked crime": and (Ac 5,4 Ac 5,9) that Peter publicly denounced Ananias and Saphira who had secretly "by fraud kept back the price of the land," without beforehand admonishing them in private: nor do we read that Our Lord admonished Judas in secret before denouncing him. Therefore the precept does not require that secret admonition should precede public denunciation.
3. Further, it is a graver matter to accuse than to denounce. Now one may go to the length of accusing a person publicly, without previously admonishing him in secret: for it is decided in the Decretal (Cap. Qualiter, xiv, De Accusationibus) that "nothing else need precede accusation except inscription." [*The accuser was bound by Roman Law to endorse (se inscribere) the writ of accusation. The effect of this endorsement or inscription was that the accuser bound himself, if he failed to prove the accusation, to suffer the same punishment as the accused would have to suffer if proved guilty.] Therefore it seems that the precept does not require that a secret admonition should precede public denunciation.
4. Further, it does not seem probable that the customs observed by religious in general are contrary to the precepts of Christ. Now it is customary among religious orders to proclaim this or that one for a fault, without any previous secret admonition. Therefore it seems that this admonition is not required by the precept.
5. Further, religious are bound to obey their prelates. Now a prelate sometimes commands either all in general, or someone in particular, to tell him if they know of anything that requires correction. Therefore it would seem that they are bound to tell them this, even before any secret admonition. Therefore the precept does not require secret admonition before public denunciation.

On the contrary Augustine says (De Verb. Dom. xvi, 4) on the words, "Rebuke him between thee and him alone" (Mt 18,15): "Aiming at his amendment, while avoiding his disgrace: since perhaps from shame he might begin to defend his sin; and him whom you thought to make a better man, you make worse." Now we are bound by the precept of charity to beware lest our brother become worse. Therefore the order of fraternal correction comes under the precept.
I answer that With regard to the public denunciation of sins it is necessary to make a distinction: because sins may be either public or secret. In the case of public sins, a remedy is required not only for the sinner, that he may become better, but also for others, who know of his sin, lest they be scandalized. Wherefore such like sins should be denounced in public, according to the saying of the Apostle (1Tm 5,20): "Them that sin reprove before all, that the rest also may have fear," which is to be understood as referring to public sins, as Augustine states (De Verb. Dom. xvi, 7).On the other hand, in the case of secret sins, the words of Our Lord seem to apply (Mt 18,15): "If thy brother shall offend against thee," etc. For if he offend thee publicly in the presence of others, he no longer sins against thee alone, but also against others whom he 'disturbs. Since, however, a man's neighbor may take offense even at his secret sins, it seems that we must make yet a further distinction. For certain secret sins are hurtful to our neighbor either in his body or in his soul, as, for instance, when a man plots secretly to betray his country to its enemies, or when a heretic secretly turns other men away from the faith. And since he that sins thus in secret, sins not only against you in particular, but also against others, it is necessary to take steps to denounce him at once, in order to prevent him doing such harm, unless by chance you were firmly persuaded that this evil result would be prevented by admonishing him secretly. On the other hand there are other sins which injure none but the sinner, and the person sinned against, either because he alone is hurt by the sinner, or at least because he alone knows about his sin, and then our one purpose should be to succor our sinning brother: and just as the physician of the body restores the sick man to health, if possible, without cutting off a limb, but, if this be unavoidable, cuts off a limb which is least indispensable, in order to preserve the life of the whole body, so too he who desires his brother's amendment should, if possible, so amend him as regards his conscience, that he keep his good name.For a good name is useful, first of all to the sinner himself, not only in temporal matters wherein a man suffers many losses, if he lose his good name, but also in spiritual matters, because many are restrained from sinning, through fear of dishonor, so that when a man finds his honor lost, he puts no curb on his sinning. Hence Jerome says on Mt 18,15: "If he sin against thee, thou shouldst rebuke him in private, lest he persist in his sin if he should once become shameless or unabashed." Secondly, we ought to safeguard our sinning brother's good name, both because the dishonor of one leads to the dishonor of others, according to the saying of Augustine (Ep ad pleb. Hipponens. lxxviii): "When a few of those who bear a name for holiness are reported falsely or proved in truth to have done anything wrong, people will seek by busily repeating it to make it believed of all": and also because when one man's sin is made public others are incited to sin likewise.Since, however, one's conscience should be preferred to a good name, Our Lord wished that we should publicly denounce our brother and so deliver his conscience from sin, even though he should forfeit his good name. Therefore it is evident that the precept requires a secret admonition to precede public denunciation.

Reply to Objection: 1. Whatever is hidden, is known to God, wherefore hidden sins are to the judgment of God, just what public sins are to the judgment of man. Nevertheless God does rebuke sinners sometimes by secretly admonishing them, so to speak, with an inward inspiration, either while they wake or while they sleep, according to Jb 33,15-17: "By a dream in a vision by night, when deep sleep falleth upon men . . . then He openeth the ears of men, and teaching instructeth them in what they are to learn, that He may withdraw a man from the things he is doing."
2. Our Lord as God knew the sin of Judas as though it were public, wherefore He could have made it known at once. Yet He did not, but warned Judas of his sin in words that were obscure. The sin of Ananias and Saphira was denounced by Peter acting as God's executor, by Whose revelation he knew of their sin. With regard to Joseph it is probable that he warned his brethren, though Scripture does not say so. Or we may say that the sin was public with regard to his brethren, wherefore it is stated in the plural that he accused "his brethren."
3. When there is danger to a great number of people, those words of Our Lord do not apply, because then thy brother does not sin against thee alone.
4. Proclamations made in the chapter of religious are about little faults which do not affect a man's good name, wherefore they are reminders of forgotten faults rather than accusations or denunciations. If, however, they should be of such a nature as to injure our brother's good name, it would be contrary to Our Lord's precept, to denounce a brother's fault in this manner.
5. A prelate is not to be obeyed contrary to a Divine precept, according to Ac 5,29: "We ought to obey God rather then men." Therefore when a prelate commands anyone to tell him anything that he knows to need correction, the command rightly understood supports the safeguarding of the order of fraternal correction, whether the command be addressed to all in general, or to some particular individual. If, on the other hand, a prelate were to issue a command in express opposition to this order instituted by Our Lord, both would sin, the one commanding, and the one obeying him, as disobeying Our Lord's command. Consequently he ought not to be obeyed, because a prelate is not the judge of secret things, but God alone is, wherefore he has no power to command anything in respect of hidden matters, except in so far as they are made known through certain signs, as by ill-repute or suspicion; in which cases a prelate can command just as a judge, whether secular or ecclesiastical, can bind a man under oath to tell the truth.

Whether before the public denunciation witnesses ought to be brought forward?

Objection: 1. It would seem that before the public denunciation witnesses ought not to be brought forward. For secret sins ought not to be made known to others, because by so doing "a man would betray his brother's sins instead of correcting them," as Augustine says (De Verb. Dom. xvi, 7). Now by bringing forward witnesses one makes known a brother's sin to others. Therefore in the case of secret sins one ought not to bring witnesses forward before the public denunciation.
2. Further, man should love his neighbor as himself. Now no man brings in witnesses to prove his own secret sin. Neither therefore ought one to bring forward witnesses to prove the secret sin of our brother.
3. Further, witnesses are brought forward to prove something. But witnesses afford no proof in secret matters. Therefore it is useless to bring witnesses forward in such cases.
4. Further, Augustine says in his Rule that "before bringing it to the notice of witnesses . . . it should be put before the superior." Now to bring a matter before a superior or a prelate is to tell the Church. Therefore witnesses should not be brought forward before the public denunciation.

On the contrary Our Lord said (Mt 18,16): "Take with thee one or two more, that in the mouth of two," etc.
I answer that The right way to go from one extreme to another is to pass through the middle space. Now Our Lord wished the beginning of fraternal correction to be hidden, when one brother corrects another between this one and himself alone, while He wished the end to be public, when such a one would be denounced to the Church. Consequently it is befitting that a citation of witnesses should be placed between the two extremes, so that at first the brother's sin be indicated to a few, who will be of use without being a hindrance, and thus his sin be amended without dishonoring him before the public.

Reply to Objection: 1. Some have understood the order of fraternal correction to demand that we should first of all rebuke our brother secretly, and that if he listens, it is well; but if he listen not, and his sin be altogether hidden, they say that we should go no further in the matter, whereas if it has already begun to reach the ears of several by various signs, we ought to prosecute the matter, according to Our Lord's command. But this is contrary to what Augustine says in his Rule that "we are bound to reveal" a brother's sin, if it "will cause a worse corruption in the heart." Wherefore we must say otherwise that when the secret admonition has been given once or several times, as long as there is probable hope of his amendment, we must continue to admonish him in private, but as soon as we are able to judge with any probability that the secret admonition is of no avail, we must take further steps, however secret the sin may be, and call witnesses, unless perhaps it were thought probable that this would not conduce to our brother's amendment, and that he would become worse: because on that account one ought to abstain altogether from correcting him, as stated above (Article [6]).
2. A man needs no witnesses that he may amend his own sin: yet they may be necessary that we may amend a brother's sin. Hence the comparison fails.
3. There may be three reasons for citing witnesses. First, to show that the deed in question is a sin, as Jerome says: secondly, to prove that the deed was done, if repeated, as Augustine says (in his Rule): thirdly, "to prove that the man who rebuked his brother, has done what he could," as Chrysostom says (Hom. in Matth. lx).
4. Augustine means that the matter ought to be made known to the prelate before it is stated to the witnesses, in so far as the prelate is a private individual who is able to be of more use than others, but not that it is to be told him as to the Church, i.e. as holding the position of judge.


We must how consider the vices opposed to charity: (1) hatred, which is opposed to love; (2) sloth and envy, which are opposed to the joy of charity; (3) discord and schism, which are contrary to peace; (4) offense and scandal, which are contrary to beneficence and fraternal correction.

Under the first head there are six points of inquiry:

(1) Whether it is possible to hate God?

(2) Whether hatred of God is the greatest of sins?

(3) Whether hatred of one's neighbor is always a sin?

(4) Whether it is the greatest of all sins against our neighbor?

(5) Whether it is a capital sin?

(6) From what capital sin does it arise?

Whether it is possible for anyone to hate God?

Objection: 1. It would seem that no man can hate God. For Dionysius says (Div. Nom. iv) that "the first good and beautiful is an object of love and dilection to all." But God is goodness and beauty itself. Therefore He is hated by none.
2. Further, in the Apocryphal books of 3 Esdras 4:36,[39] it is written that "all things call upon truth . . . and (all men) do well like of her works." Now God is the very truth according to Jn 14,6. Therefore all love God, and none can hate Him.
3. Further, hatred is a kind of aversion. But according to Dionysius (Div. Nom. i) God draws all things to Himself. Therefore none can hate Him.

On the contrary It is written (Ps 73,23): "The pride of them that hate Thee ascendeth continually," and (Jn 15,24): "But now they have both seen and hated both Me and My Father."
I answer that As shown above (FS, Question [29], Article [1]), hatred is a movement of the appetitive power, which power is not set in motion save by something apprehended. Now God can be apprehended by man in two ways; first, in Himself, as when He is seen in His Essence; secondly, in His effects, when, to wit, "the invisible things" of God . . . "are clearly seen, being understood by the things that are made" (Rm 1,20). Now God in His Essence is goodness itself, which no man can hate---for it is natural to good to be loved. Hence it is impossible for one who sees God in His Essence, to hate Him.Moreover some of His effects are such that they can nowise be contrary to the human will, since "to be, to live, to understand," which are effects of God, are desirable and lovable to all. Wherefore again God cannot be an object of hatred if we consider Him as the Author of such like effects. Some of God's effects, however, are contrary to an inordinate will, such as the infliction of punishment, and the prohibition of sin by the Divine Law. Such like effects are repugnant to a will debased by sin, and as regards the consideration of them, God may be an object of hatred to some, in so far as they look upon Him as forbidding sin, and inflicting punishment.

Reply to Objection: 1. This argument is true of those who see God's Essence, which is the very essence of goodness.
2. This argument is true in so far as God is apprehended as the cause of such effects as are naturally beloved of all, among which are the works of Truth who reveals herself to men.
3. God draws all things to Himself, in so far as He is the source of being, since all things, in as much as they are, tend to be like God, Who is Being itself.

Whether hatred of God is the greatest of sins?

Objection: 1. It would seem that hatred of God is not the greatest of sins. For the most grievous sin is the sin against the Holy Ghost, since it cannot be forgiven, according to Mt 12,32. Now hatred of God is not reckoned among the various kinds of sin against the Holy Ghost, as may be seen from what has been said above (Question [14], Article [2]). Therefore hatred of God is not the most grievous sin.
2. Further, sin consists in withdrawing oneself from God. Now an unbeliever who has not even knowledge of God seems to be further away from Him than a believer, who though he hate God, nevertheless knows Him. Therefore it seems that the sin of unbelief is graver than the sin of hatred against God.
3. Further, God is an object of hatred, only by reason of those of His effects that are contrary to the will: the chief of which is punishment. But hatred of punishment is not the most grievous sin. Therefore hatred of God is not the most grievous sin.

On the contrary The best is opposite to the worst, according to the Philosopher (Ethic. viii, 10). But hatred of God is contrary to the love of God, wherein man's best consists. Therefore hatred of God is man's worst sin.
I answer that The defect in sin consists in its aversion from God, as stated above (Question [10], Article [3]): and this aversion would not have the character of guilt, were it not voluntary. Hence the nature of guilt consists in a voluntary aversion from God.Now this voluntary aversion from God is directly implied in the hatred of God, but in other sins, by participation and indirectly. For just as the will cleaves directly to what it loves, so does it directly shun what it hates. Hence when a man hates God, his will is directly averted from God, whereas in other sins, fornication for instance, a man turns away from God, not directly, but indirectly, in so far, namely, as he desires an inordinate pleasure, to which aversion from God is connected. Now that which is so by itself, always takes precedence of that which is so by another. Wherefore hatred of God is more grievous than other sins.

Reply to Objection: 1. According to Gregory (Moral. xxv, 11), "it is one thing not to do good things, end another to hate the giver of good things, even as it is one thing to sin indeliberately, and another to sin deliberately." This implies that to hate God, the giver of all good things, is to sin deliberately, and this is a sin against the Holy Ghost. Hence it is evident that hatred of God is chiefly a sin against the Holy Ghost, in so far as the sin against the Holy Ghost denotes a special kind of sin: and yet it is not reckoned among the kinds of sin against the Holy Ghost, because it is universally found in every kind of that sin.
2. Even unbelief is not sinful unless it be voluntary: wherefore the more voluntary it is, the more it is sinful. Now it becomes voluntary by the fact that a man hates the truth that is proposed to him. Wherefore it is evident that unbelief derives its sinfulness from hatred of God, Whose truth is the object of faith; and hence just as a cause is greater than its effect, so hatred of God is a greater sin than unbelief.
3. Not everyone who hates his punishment, hates God the author of punishments. For many hate the punishments inflicted on them, and yet they bear them patiently out of reverence for the Divine justice. Wherefore Augustine says (Confess. x) that God commands us to bear with penal evils, not to love them. On the other hand, to break out into hatred of God when He inflicts those punishments, is to hate God's very justice, and that is a most grievous sin. Hence Gregory says (Moral. xxv, 11): "Even as sometimes it is more grievous to love sin than to do it, so is it more wicked to hate justice than, not to have done it."

Whether hatred of one's neighbor is always a sin?

Objection: 1. It would seem that hatred of one's neighbor is not always a sin. For no sin is commanded or counselled by God, according to Pr 8,8: "All My words are just, there is nothing wicked nor perverse in them." Now, it is written (Lc 14,26): "If any man come to Me, and hate not his father and mother . . . he cannot be My disciple." Therefore hatred of one's neighbor is not always a sin.
2. Further, nothing wherein we imitate God can be a sin. But it is in imitation of God that we hate certain people: for it is written (Rm 1,30): "Detractors, hateful to God." Therefore it is possible to hate certain people without committing a sin.
3. Further, nothing that is natural is a sin, for sin is a "wandering away from what is according to nature," according to Damascene (De Fide Orth. ii, 4,30; iv, 20). Now it is natural to a thing to hate whatever is contrary to it, and to aim at its undoing. Therefore it seems that it is not a sin to hate one's I enemy.

On the contrary It is written (1Jn 2,9): "He that . . . hateth his brother, is in darkness." Now spiritual darkness is sin. Therefore there cannot be hatred of one's neighbor without sin.
I answer that Hatred is opposed to love, as stated above (FS, Question [29], Article [2]); so that hatred of a thing is evil according as the love of that thing is good. Now love is due to our neighbor in respect of what he holds from God, i.e. in respect of nature and grace, but not in respect of what he has of himself and from the devil, i.e. in respect of sin and lack of justice.Consequently it is lawful to hate the sin in one's brother, and whatever pertains to the defect of Divine justice, but we cannot hate our brother's nature and grace without sin. Now it is part of our love for our brother that we hate the fault and the lack of good in him, since desire for another's good is equivalent to hatred of his evil. Consequently the hatred of one's brother, if we consider it simply, is always sinful.

Reply to Objection: 1. By the commandment of God (Ex 20,12) we must honor our parents---as united to us in nature and kinship. But we must hate them in so far as they prove an obstacle to our attaining the perfection of Divine justice.
2. God hates the sin which is in the detractor, not his nature: so that we can hate detractors without committing a sin.
3. Men are not opposed to us in respect of the goods which they have received from God: wherefore, in this respect, we should love them. But they are opposed to us, in so far as they show hostility towards us, and this is sinful in them. In this respect we should hate them, for we should hate in them the fact that they are hostile to us.

Whether hatred of our neighbor is the most grievous sin against our neighbor?

Objection: 1. It would seem that hatred of our neighbor is the most grievous sin against our neighbor. For it is written (1Jn 3,15): "Whosoever hateth his brother is a murderer." Now murder is the most grievous of sins against our neighbor. Therefore hatred is also.
2. Further, worst is opposed to best. Now the best thing we give our neighbor is love, since all other things are referable to love. Therefore hatred is the worst.

On the contrary A thing is said to be evil, because it hurts, as Augustine observes (Enchiridion xii). Now there are sins by which a man hurts his neighbor more than by hatred, e.g. theft, murder and adultery. Therefore hatred is not the most grievous sin.Moreover, Chrysostom [*Hom. x in the Opus Imperfectum, falsely ascribed to St. John Chrysostom] commenting on Mt 5,19, "He that shall break one of these least commandments," says: "The commandments of Moses, Thou shalt not kill, Thou shalt not commit adultery, count for little in their reward, but they count for much if they be disobeyed. On the other hand the commandments of Christ such as, Thou shalt not be angry, Thou shalt not desire, are reckoned great in their reward, but little in the transgression." Now hatred is an internal movement like anger and desire. Therefore hatred of one's brother is a less grievous sin than murder.
I answer that Sins committed against our neighbor are evil on two counts; first by reason of the disorder in the person who sins, secondly by reason of the hurt inflicted on the person sinned against. On the first count, hatred is a more grievous sin than external actions that hurt our neighbor, because hatred is a disorder of man's will, which is the chief part of man, and wherein is the root of sin, so that if a man's outward actions were to be inordinate, without any disorder in his will, they would not be sinful, for instance, if he were to kill a man, through ignorance or out of zeal for justice: and if there be anything sinful in a man's outward sins against his neighbor, it is all to be traced to his inward hatred.On the other hand, as regards the hurt inflicted on his neighbor, a man's outward sins are worse than his inward hatred.

Reply to Objection: 1. This suffices for the Replies to the Objections.

Whether hatred is a capital sin?

Objection: 1. It would seem that hatred is a capital sin. For hatred is directly opposed to charity. Now charity is the foremost among the virtues, and the mother of all others. Therefore hatred is the chief of the capital sins, and the origin of all others.
2. Further, sins arise in us on account of the inclinations of our passions, according to Rm 7,5: "The passions of sins . . . did work in our members to bring forth fruit unto death." Now all other passions of the soul seem to arise from love and hatred, as was shown above (FS, Question [25], Articles [1],2). Therefore hatred should be reckoned one of the capital sins.
3. Further, vice is a moral evil. Now hatred regards evil more than any other passion does. Therefore it seems that hatred should be reckoned a capital sin.

On the contrary Gregory (Moral. xxxi) does not reckon hatred among the seven capital sins.
I answer that As stated above (FS, Question [84], Articles [3],4), a capital vice is one from which other vices arise most frequently. Now vice is contrary to man's nature, in as much as he is a rational animal: and when a thing acts contrary to its nature, that which is natural to it is corrupted little by little. Consequently it must first of all fail in that which is less in accordance with its nature, and last of all in that which is most in accordance with its nature, since what is first in construction is last in destruction. Now that which, first and foremost, is most natural to man, is the love of what is good, and especially love of the Divine good, and of his neighbor's good. Wherefore hatred, which is opposed to this love, is not the first but the last thing in the downfall of virtue resulting from vice: and therefore it is not a capital vice.

Reply to Objection: 1. As stated in Phys. vii, text. 18, "the virtue of a thing consists in its being well disposed in accordance with its nature." Hence what is first and foremost in the virtues must be first and foremost in the natural order. Hence charity is reckoned the foremost of the virtues, and for the same reason hatred cannot be first among the vices, as stated above.
2. Hatred of the evil that is contrary to one's natural good, is the first of the soul's passions, even as love of one's natural good is. But hatred of one's connatural good cannot be first, but is something last, because such like hatred is a proof of an already corrupted nature, even as love of an extraneous good.
3. Evil is twofold. One is a true evil, for the reason that it is incompatible with one's natural good, and the hatred of such an evil may have priority over the other passions. There is, however, another which is not a true, but an apparent evil, which, namely, is a true and connatural good, and yet is reckoned evil on account of the corruption of nature: and the hatred of such an evil must needs come last. This hatred is vicious, but the former is not.

Whether hatred arises from envy?

Objection: 1. It seems that hatred does not arise from envy. For envy is sorrow for another's good. Now hatred does not arise from sorrow, for, on the contrary, we grieve for the presence of the evil we hate. Therefore hatred does not arise from envy.
2. Further, hatred is opposed to love. Now love of our neighbor is referred to our love of God, as stated above (Question [25], Article [1]; Question [26], Article [2]). Therefore hatred of our neighbor is referred to our hatred of God. But hatred of God does not arise from envy, for we do not envy those who are very far removed from us, but rather those who seem to be near us, as the Philosopher states (Rhet. ii). Therefore hatred does not arise from envy.
3. Further, to one effect there is one cause. Now hatred is caused by anger, for Augustine says in his Rule that "anger grows into hatred." Therefore hatred does not arise from envy.

On the contrary Gregory says (Moral. xxxi, 45) that "out of envy cometh hatred."
I answer that As stated above (Article [5]), hatred of his neighbor is a man's last step in the path of sin, because it is opposed to the love which he naturally has for his neighbor. Now if a man declines from that which is natural, it is because he intends to avoid that which is naturally an object to be shunned. Now every animal naturally avoids sorrow, just as it desires pleasure, as the Philosopher states (Ethic. vii, x). Accordingly just as love arises from pleasure, so does hatred arise from sorrow. For just as we are moved to love whatever gives us pleasure, in as much as for that very reason it assumes the aspect of good; so we are moved to hate whatever displeases us, in so far as for this very reason it assumes the aspect of evil. Wherefore, since envy is sorrow for our neighbor's good, it follows that our neighbor's good becomes hateful to us, so that "out of envy cometh hatred."

Reply to Objection: 1. Since the appetitive power, like the apprehensive power, reflects on its own acts, it follows that there is a kind of circular movement in the actions of the appetitive power. And so according to the first forward course of the appetitive movement, love gives rise to desire, whence follows pleasure when one has obtained what one desired. And since the very fact of taking pleasure in the good one loves is a kind of good, it follows that pleasure causes love. And in the same way sorrow causes hatred.
2. Love and hatred are essentially different, for the object of love is good, which flows from God to creatures, wherefore love is due to God in the first place, and to our neighbor afterwards. On the other hand, hatred is of evil, which has no place in God Himself, but only in His effects, for which reason it has been stated above (Article [1]), that God is not an object of hatred, except in so far as He is considered in relation to His effects, and consequently hatred is directed to our neighbor before being directed to God. Therefore, since envy of our neighbor is the mother of hatred of our neighbor, it becomes, in consequence, the cause of hatred towards God.
3. Nothing prevents a thing arising from various causes in various respects, and accordingly hatred may arise both from anger and from envy. However it arises more directly from envy, which looks upon the very good of our neighbor as displeasing and therefore hateful, whereas hatred arises from anger by way of increase. For at first, through anger, we desire our neighbor's evil according to a certain measure, that is in so far as that evil has the aspect of vengeance: but afterwards, through the continuance of anger, man goes so far as absolutely to desire his neighbor's evil, which desire is part of hatred. Wherefore it is evident that hatred is caused by envy formally as regards the aspect of the object, but dispositively by anger.
