Reply to Objection 4: We love sinners out of charity, not so as to will what they will, or to rejoice in what gives them joy, but so as to make them will what we will, and rejoice in what rejoices us. Hence it is written ( Jer. 15:19 ): "They shall be turned to thee, and thou shalt not to be turned to them."
Reply to Objection 5: The weak should avoid associating with sinners, on account of the danger in which they stand of being perverted by them. But it is commendable for the perfect, of whose perversion there is no fear, to associate with sinners that they may convert them. For thus did Our Lord eat and drink with sinners as related by Mat. 9:11-13. Yet all should avoid the society of sinners, as regards fellowship in sin; in this sense it is written ( 2 Cor. 6:17 ): "Go out from among them . . . and touch not the unclean thing," i.e. by consenting to sin.
Whether sinners love themselves?
Objection 1: It would seem that sinners love themselves. For that which is the principle of sin, is most of all in the sinner. Now love of self is the principle of sin, since Augustine says (De Civ. Dei xiv, 28) that it "builds up the city of Babylon." Therefore sinners most of all love themselves.
Objection 2: Further, sin does not destroy nature. Now it is in keeping with nature that every man should love himself: wherefore even irrational creatures naturally desire their own good, for instance, the preservation of their being, and so forth. Therefore sinners love themselves.
Objection 3: Further, good is beloved by all, as Dionysius states (Div. Nom. iv). Now many sinners reckon themselves to be good. Therefore many sinners love themselves.
On the contrary, It is written ( Ps. 10:6 ): "He that loveth iniquity, hateth his own soul."
I answer that, Love of self is common to all, in one way; in another way it is proper to the good; in a third way, it is proper to the wicked. For it is common to all for each one to love what he thinks himself to be. Now a man is said to be a thing, in two ways: first, in respect of his substance and nature, and, this way all think themselves to be what they are, that is, composed of a soul and body. In this way too, all men, both good and wicked, love themselves, in so far as they love their own preservation.
Secondly, a man is said to be something in respect of some predominance, as the sovereign of a state is spoken of as being the state, and so, what the sovereign does, the state is said to do. In this way, all do not think themselves to be what they are. For the reasoning mind is the predominant part of man, while the sensitive and corporeal nature takes the second place, the former of which the Apostle calls the "inward man," and the latter, the "outward man" ( 2 Cor. 4:16 ). Now the good look upon their rational nature or the inward man as being the chief thing in them, wherefore in this way they think themselves to be what they are. On the other hand, the wicked reckon their sensitive and corporeal nature, or the outward man, to hold the first place. Wherefore, since they know not themselves aright, they do not love themselves aright, but love what they think themselves to be. But the good know themselves truly, and therefore truly love themselves.
The Philosopher proves this from five things that are proper to friendship. For in the first place, every friend wishes his friend to be and to live; secondly, he desires good things for him; thirdly, he does good things to him; fourthly, he takes pleasure in his company; fifthly, he is of one mind with him, rejoicing and sorrowing in almost the same things. In this way the good love themselves, as to the inward man, because they wish the preservation thereof in its integrity, they desire good things for him, namely spiritual goods, indeed they do their best to obtain them, and they take pleasure in entering into their own hearts, because they find there good thoughts in the present, the memory of past good, and the hope of future good, all of which are sources of pleasure. Likewise they experience no clashing of wills, since their whole soul tends to one thing.
On the other hand, the wicked have no wish to be preserved in the integrity of the inward man, nor do they desire spiritual goods for him, nor do they work for that end, nor do they take pleasure in their own company by entering into their own hearts, because whatever they find there, present, past and future, is evil and horrible; nor do they agree with themselves, on account of the gnawings of conscience, according to Ps. 49:21 : "I will reprove thee and set before thy face."
In the same manner it may be shown that the wicked love themselves, as regards the corruption of the outward man, whereas the good do not love themselves thus.
Reply to Objection 1: The love of self which is the principle of sin is that which is proper to the wicked, and reaches "to the contempt of God," as stated in the passage quoted, because the wicked so desire external goods as to despise spiritual goods.
Reply to Objection 2: Although natural love is not altogether forfeited by wicked men, yet it is perverted in them, as explained above.
Reply to Objection 3: The wicked have some share of self-love, in so far as they think themselves good. Yet such love of self is not true but apparent: and even this is not possible in those who are very wicked.
Whether charity requires that we should love our enemies?
Objection 1: It would seem that charity does not require us to love our enemies. For Augustine says (Enchiridion lxxiii) that "this great good," namely, the love of our enemies, is "not so universal in its application, as the object of our petition when we say: Forgive us our trespasses." Now no one is forgiven sin without he have charity, because, according to Prov. 10:12, "charity covereth all sins." Therefore charity does not require that we should love our enemies.
Objection 2: Further, charity does not do away with nature. Now everything, even an irrational being, naturally hates its contrary, as a lamb hates a wolf, and water fire. Therefore charity does not make us love our enemies.
Objection 3: Further, charity "doth nothing perversely" ( 1 Cor. 13:4 ). Now it seems perverse to love one's enemies, as it would be to hate one's friends: hence Joab upbraided David by saying ( 2 Kings 19:6): "Thou lovest them that hate thee, and thou hatest them that love thee." Therefore charity does not make us love our enemies.
On the contrary, Our Lord said ( Mat. 4:44 ): "Love your enemies."
I answer that, Love of one's enemies may be understood in three ways. First, as though we were to love our enemies as such: this is perverse, and contrary to charity, since it implies love of that which is evil in another.
Secondly love of one's enemies may mean that we love them as to their nature, but in general: and in this sense charity requires that we should love our enemies, namely, that in loving God and our neighbor, we should not exclude our enemies from the love given to our neighbor in general.
Thirdly, love of one's enemies may be considered as specially directed to them, namely, that we should have a special movement of love towards our enemies. Charity does not require this absolutely, because it does not require that we should have a special movement of love to every individual man, since this would be impossible. Nevertheless charity does require this, in respect of our being prepared in mind, namely, that we should be ready to love our enemies individually, if the necessity were to occur. That man should actually do so, and love his enemy for God's sake, without it being necessary for him to do so, belongs to the perfection of charity. For since man loves his neighbor, out of charity, for God's sake, the more he loves God, the more does he put enmities aside and show love towards his neighbor: thus if we loved a certain man very much, we would love his children though they were unfriendly towards us. This is the sense in which Augustine speaks in the passage quoted in the First Objection, the Reply to which is therefore evident.
Reply to Objection 2: Everything naturally hates its contrary as such. Now our enemies are contrary to us, as enemies, wherefore this itself should be hateful to us, for their enmity should displease us. They are not, however, contrary to us, as men and capable of happiness: and it is as such that we are bound to love them.
Reply to Objection 3: It is wrong to love one's enemies as such: charity does not do this, as stated above.
