Thomas Aquinas

“ 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. ”

“ 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. ”

“ When, however, they fall into very great wickedness, and become incurable, we ought no longer to show them friendliness. It is for this reason that both Divine and human laws command such like sinners to be put to death, because there is greater likelihood of their harming others than of their mending their ways. Nevertheless the judge puts this into effect, not out of hatred for the sinners, but out of the love of charity, by reason of which he prefers the public good to the life of the individual. ”

“ 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. ”

“ On the contrary, The love of charity extends to none but God and our neighbor. But the word neighbor cannot be extended to irrational creatures, since they have no fellowship with man in the rational life. Therefore charity does not extend to irrational creatures. ”

“ First, a thing may be loved as the person who is the object of friendship, and thus we cannot have the friendship of charity towards the demons. For it is an essential part of friendship that one should be a well-wisher towards one's friend; and it is impossible for us, out of charity, to desire the good of everlasting life, to which charity is referred, for those spirits whom God has condemned eternally, since this would be in opposition to our charity towards God whereby we approve of His justice.
Secondly, we love a thing as being that which we desire to be enduring as another's good. ”

“ Those who love themselves are to be blamed, in so far as they love themselves as regards their sensitive nature, which they humor. This is not to love oneself truly according to one's rational nature, so as to desire for oneself the good things which pertain to the perfection of reason: and in this way chiefly it is through charity that a man loves himself. ”

“ It is wrong to hope in man as though he were the principal author of salvation, but not, to hope in man as helping us ministerially under God. In like manner it would be wrong if a man loved his neighbor as though he were his last end, but not, if he loved him for God's sake; and this is what charity does. ”

“ Our neighbor is not only one who is united to us in a common species, but also one who is united to us by sharing in the blessings pertaining to everlasting life, and it is on the latter fellowship that the friendship of charity is founded. ”

“ Hence love is not differentiated specifically on account of the various degrees of goodness in various persons, so long as it is referred to one good common to all, whereas honor is distinguished according to the good belonging to individuals. Consequently we love all our neighbors with the same love of charity, in so far as they are referred to one good common to them all, which is God; whereas we give various honors to various people, according to each one's own virtue, and likewise to God we give the singular honor of latria on account of His singular virtue. ”

“ Consequently, out of the love of charity with which we love God, we ought to love our bodies also, but we ought not to love the evil effects of sin and the corruption of punishment; we ought rather, by the desire of charity, to long for the removal of such things. ”

“ Hence charity towards our neighbor cannot be without producing works. But charity requires us to love our neighbor without exception, though he be an enemy. Therefore charity requires us to show the signs and effects of love towards our enemies. ”

“ Two of these reasons refer in a general way to friendship, which cannot have an irrational creature for its object: first because friendship is towards one to whom we wish good things, while, properly speaking, we cannot wish good things to an irrational creature, because it is not competent, properly speaking, to possess good, this being proper to the rational creature which, through its free-will, is the master of its disposal of the good it possesses. ”

“ Nevertheless we can love irrational creatures out of charity, if we regard them as the good things that we desire for others, in so far, to wit, as we wish for their preservation, to God's honor and man's use; thus too does God love them out of charity. ”

“ God and our neighbor are those with whom we are friends, but love of them includes the loving of charity, since we love both God and our neighbor, in so far as we love ourselves and our neighbor to love God, and this is to love charity. ”

“ Now the love of friendship is twofold: first, there is the love for the friend to whom our friendship is given, secondly, the love for those good things which we desire for our friend. With regard to the first, no irrational creature can be loved out of charity ”

“ Consequently the habit of charity extends not only to the love of God, but also to the love of our neighbor.
Reply to Objection 1: We may fear our neighbor, even as we may love him, in two ways: first, on account of something that is proper to him, as when a man fears a tyrant on account of his cruelty, or loves him by reason of his own desire to get something from him. Such like human fear is distinct from the fear of God, and the same applies to love. Secondly, we fear a man, or love him on account of what he has of God ”

“ For if we have friendship with others it is because we do unto them as we do unto ourselves, hence we read in Ethic. ix, 4,8, that "the origin of friendly relations with others lies in our relations to ourselves." Thus too with regard to principles we have something greater than science, namely understanding.
Secondly, we may speak of charity in respect of its specific nature, namely as denoting man's friendship with God in the first place, and, consequently, with the things of God, among which things is man himself who has charity. ”

“ 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. ”

“ 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. ”

“ Further, anything relating to charity cannot be blameworthy, since charity "dealeth not perversely" (1 Cor. 23:4) . Now a man deserves to be blamed for loving himself, since it is written (2 Tim. 3:1,2) : "In the last days shall come dangerous times, men shall be lovers of themselves." Therefore a man cannot love himself out of charity. ”

“ 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. ”

“ Now the aspect under which our neighbor is to be loved, is God, since what we ought to love in our neighbor is that he may be in God. Hence it is clear that it is specifically the same act whereby we love God, and whereby we love our neighbor. ”

“ Moreover the death inflicted by the judge profits the sinner, if he be converted, unto the expiation of his crime; and, if he be not converted, it profits so as to put an end to the sin, because the sinner is thus deprived of the power to sin any more. ”

“ Further, it is proper to friends to rejoice in, and will the same things. Now charity does not make us will what sinners will, nor to rejoice in what gives them joy, but rather the contrary. Therefore sinners should not be loved out of charity. ”

“ Accordingly, since the relation between the human lover and God is different from his relation to himself, these two are reckoned as distinct objects of love, for the love of the one is the cause of the love of the other, so that the former love being removed the latter is taken away. ”

“ 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. ”

“ 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. ”
