Of the Subject of Charity

I answer that, Since, as stated in the First Part (Q. 80, A. 2), the appetite is twofold, namely the sensitive, and the intellective which is called the will, the object of each is the good, but in different ways: for the object of the sensitive appetite is a good apprehended by sense, whereas the object of the intellective appetite or will is good under the universal aspect of good, according as it can be apprehended by the intellect. Now the object of charity is not a sensible good, but the Divine good which is known by the intellect alone. Therefore the subject of charity is not the sensitive, but the intellective appetite, i.e. the will.

I answer that, As stated above (Q. 23, A. 1), charity is a friendship of man for God, founded upon the fellowship of everlasting happiness. Now this fellowship is in respect, not of natural, but of gratuitous gifts, for, according to Rom. 6:23, "the grace of God is life everlasting": wherefore charity itself surpasses our natural facilities. Now that which surpasses the faculty of nature, cannot be natural or acquired by the natural powers, since a natural effect does not transcend its cause.

Therefore charity can be in us neither naturally, nor through acquisition by the natural powers, but by the infusion of the Holy Ghost, Who is the love of the Father and the Son, and the participation of Whom in us is created charity, as stated above (Q. 23, A. 2).

I answer that, The quantity of a thing depends on the proper cause of that thing, since the more universal cause produces a greater effect. Now, since charity surpasses the proportion of human nature, as stated above (A. 2) it depends, not on any natural virtue, but on the sole grace of the Holy Ghost Who infuses charity. Wherefore the quantity of charity depends neither on the condition of nature nor on the capacity of natural virtue, but only on the will of the Holy Ghost Who "divides" His gifts "according as He will." Hence the Apostle says (Eph. 4:7): "To every one of us is given grace according to the measure of the giving of Christ."

I answer that, The charity of a wayfarer can increase. For we are called wayfarers by reason of our being on the way to God, Who is the last end of our happiness. In this way we advance as we get nigh to God, Who is approached, "not by steps of the body but by the affections of the soul" [St. Augustine, Tract. in Joan. xxxii]: and this approach is the result of charity, since it unites man's mind to God. Consequently it is essential to the charity of a wayfarer that it can increase, for if it could not, all further advance along the way would cease. Hence the Apostle calls charity the way, when he says (1 Cor. 12:31): "I show unto you yet a more excellent way."

I answer that, Every addition is of something to something else: so that in every addition we must at least presuppose that the things added together are distinct before the addition. Consequently if charity be added to charity, the added charity must be presupposed as distinct from charity to which it is added, not necessarily by a distinction of reality, but at least by a distinction of thought. For God is able to increase a bodily quantity by adding a magnitude which did not exist before, but was created at that very moment; which magnitude, though not pre-existent in reality, is nevertheless capable of being distinguished from the quantity to which it is added. Wherefore if charity be added to charity we must presuppose the distinction, at least logical, of the one charity from the other.

Now distinction among forms is twofold: specific and numeric. Specific distinction of habits follows diversity of objects, while numeric distinction follows distinction of subjects. Consequently a habit may receive increase through extending to objects to which it did not extend before: thus the science of geometry increases in one who acquires knowledge of geometrical matters which he ignored hitherto. But this cannot be said of charity, for even the slightest charity extends to all that we have to love by charity. Hence the addition which causes an increase of charity cannot be understood, as though the added charity were presupposed to be distinct specifically from that to which it is added.

It follows therefore that if charity be added to charity, we must presuppose a numerical distinction between them, which follows a distinction of subjects: thus whiteness receives an increase when one white thing is added to another, although such an increase does not make a thing whiter. This, however, does not apply to the case in point, since the subject of charity is none other than the rational mind, so that such like an increase of charity could only take place by one rational mind being added to another; which is impossible. Moreover, even if it were possible, the result would be a greater lover, but not a more loving one. It follows, therefore, that charity can by no means increase by addition of charity to charity, as some have held to be the case.

Accordingly charity increases only by its subject partaking of charity more and more subject thereto. For this is the proper mode of increase in a form that is intensified, since the being of such a form consists wholly in its adhering to its subject. Consequently, since the magnitude of a thing follows on its being, to say that a form is greater is the same as to say that it is more in its subject, and not that another form is added to it: for this would be the case if the form, of itself, had any quantity, and not in comparison with its subject. Therefore charity increases by being intensified in its subject, and this is for charity to increase in its essence; and not by charity being added to charity.

I answer that, The spiritual increase of charity is somewhat like the increase of a body. Now bodily increase in animals and plants is not a continuous movement, so that, to wit, if a thing increase so much in so much time, it need to increase proportionally in each part of that time, as happens in local movement; but for a certain space of time nature works by disposing for the increase, without causing any actual increase, and afterwards brings into effect that to which it had disposed, by giving the animal or plant an actual increase. In like manner charity does not actually increase through every act of charity, but each act of charity disposes to an increase of charity, in so far as one act of charity makes man more ready to act again according to charity, and this readiness increasing, man breaks out into an act of more fervent love, and strives to advance in charity, and then his charity increases actually.

I answer that, A term to the increase of a form may be fixed in three ways: first by reason of the form itself having a fixed measure, and when this has been reached it is no longer possible to go any further in that form, but if any further advance is made, another form is attained. An example of this is paleness, the bounds of which may, by continual alteration, be passed, either so that whiteness ensues, or so that blackness results. Secondly, on the part of the agent, whose power does not extend to a further increase of the form in its subject. Thirdly, on the part of the subject, which is not capable of ulterior perfection.

Now, in none of these ways, is a limit imposed to the increase of man's charity, while he is in the state of the wayfarer. For charity itself considered as such has no limit to its increase, since it is a participation of the infinite charity which is the Holy Ghost. In like manner the cause of the increase of charity, viz. God, is possessed of infinite power. Furthermore, on the part of its subject, no limit to this increase can be determined, because whenever charity increases, there is a corresponding increased ability to receive a further increase. It is therefore evident that it is not possible to fix any limits to the increase of charity in this life.

I answer that, The perfection of charity may be understood in two ways: first with regard to the object loved, secondly with regard to the person who loves. With regard to the object loved, charity is perfect, if the object be loved as much as it is lovable. Now God is as lovable as He is good, and His goodness is infinite, wherefore He is infinitely lovable. But no creature can love Him infinitely since all created power is finite. Consequently no creature's charity can be perfect in this way; the charity of God alone can, whereby He loves Himself.

On the part of the person who loves, charity is perfect, when he loves as much as he can. This happens in three ways. First, so that a man's whole heart is always actually borne towards God: this is the perfection of the charity of heaven, and is not possible in this life, wherein, by reason of the weakness of human life, it is impossible to think always actually of God, and to be moved by love towards Him. Secondly, so that man makes an earnest endeavor to give his time to God and Divine things, while scorning other things except in so far as the needs of the present life demand. This is the perfection of charity that is possible to a wayfarer; but is not common to all who have charity. Thirdly, so that a man gives his whole heart to God habitually, viz. by neither thinking nor desiring anything contrary to the love of God; and this perfection is common to all who have charity.

I answer that, The spiritual increase of charity may be considered in respect of a certain likeness to the growth of the human body. For although this latter growth may be divided into many parts, yet it has certain fixed divisions according to those particular actions or pursuits to which man is brought by this same growth. Thus we speak of a man being an infant until he has the use of reason, after which we distinguish another state of man wherein he begins to speak and to use his reason, while there is again a third state, that of puberty when he begins to acquire the power of generation, and so on until he arrives at perfection.

In like manner the divers degrees of charity are distinguished according to the different pursuits to which man is brought by the increase of charity. For at first it is incumbent on man to occupy himself chiefly with avoiding sin and resisting his concupiscences, which move him in opposition to charity: this concerns beginners, in whom charity has to be fed or fostered lest it be destroyed: in the second place man's chief pursuit is to aim at progress in good, and this is the pursuit of the proficient, whose chief aim is to strengthen their charity by adding to it: while man's third pursuit is to aim chiefly at union with and enjoyment of God: this belongs to the perfect who "desire to be dissolved and to be with Christ."

In like manner we observe in local motion that at first there is withdrawal from one term, then approach to the other term, and thirdly, rest in this term.

I answer that, The quantity which charity has in comparison with its proper object, cannot decrease, even as neither can it increase, as stated above (A. 4, ad 2).

Since, however, it increases in that quantity which it has in comparison with its subject, here is the place to consider whether it can decrease in this way. Now, if it decrease, this must needs be either through an act, or by the mere cessation from act. It is true that virtues acquired through acts decrease and sometimes cease altogether through cessation from act, as stated above (I-II, Q. 53, A. 3). Wherefore the Philosopher says, in reference to friendship (Ethic. viii, 5) "that want of intercourse," i.e. the neglect to call upon or speak with one's friends, "has destroyed many a friendship." Now this is because the safe-keeping of a thing depends on its cause, and the cause of human virtue is a human act, so that when human acts cease, the virtue acquired thereby decreases and at last ceases altogether. Yet this does not occur to charity, because it is not the result of human acts, but is caused by God alone, as stated above (A. 2). Hence it follows that even when its act ceases, it does not for this reason decrease, or cease altogether, unless the cessation involves a sin.

The consequence is that a decrease of charity cannot be caused except either by God or by some sinful act. Now no defect is caused in us by God, except by way of punishment, in so far as He withdraws His grace in punishment of sin. Hence He does not diminish charity except by way of punishment: and this punishment is due on account of sin.

It follows, therefore, that if charity decrease, the cause of this decrease must be sin either effectively or by way of merit. But mortal sin does not diminish charity, in either of these ways, but destroys it entirely, both effectively, because every mortal sin is contrary to charity, as we shall state further on (A. 12), and by way of merit, since when, by sinning mortally, a man acts against charity, he deserves that God should withdraw charity from him.

In like manner, neither can venial sin diminish charity either effectively or by way of merit. Not effectively, because it does not touch charity, since charity is about the last end, whereas venial sin is a disorder about things directed to the end: and a man's love for the end is none the less through his committing an inordinate act as regards the things directed to the end. Thus sick people sometimes, though they love health much, are irregular in keeping to their diet: and thus again, in speculative sciences, the false opinions that are derived from the principles, do not diminish the certitude of the principles. So too, venial sin does not merit diminution of charity; for when a man offends in a small matter he does not deserve to be mulcted in a great matter. For God does not turn away from man, more than man turns away from Him: wherefore he that is out of order in respect of things directed to the end, does not deserve to be mulcted in charity whereby he is ordered to the last end.

The consequence is that charity can by no means be diminished, if we speak of direct causality, yet whatever disposes to its corruption may be said to conduce indirectly to its diminution, and such are venial sins, or even the cessation from the practice of works of charity.

I answer that, The Holy Ghost dwells in us by charity, as shown above (A. 2; QQ. 23, 24). We can, accordingly, consider charity in three ways: first on the part of the Holy Ghost, Who moves the soul to love God, and in this respect charity is incompatible with sin through the power of the Holy Ghost, Who does unfailingly whatever He wills to do. Hence it is impossible for these two things to be true at the same time—that the Holy Ghost should will to move a certain man to an act of charity, and that this man, by sinning, should lose charity. For the gift of perseverance is reckoned among the blessings of God whereby "whoever is delivered, is most certainly delivered," as Augustine says in his book on the Predestination of the saints (De Dono Persev. xiv).

Secondly, charity may be considered as such, and thus it is incapable of anything that is against its nature. Wherefore charity cannot sin at all, even as neither can heat cool, nor unrighteousness do good, as Augustine says (De Serm. Dom. in Monte ii, 24).

Thirdly, charity can be considered on the part of its subject, which is changeable on account of the free-will. Moreover charity may be compared with this subject, both from the general point of view of form in comparison with matter, and from the specific point of view of habit as compared with power. Now it is natural for a form to be in its subject in such a way that it can be lost, when it does not entirely fill the potentiality of matter: this is evident in the forms of things generated and corrupted, because the matter of such things receives one form in such a way, that it retains the potentiality to another form, as though its potentiality were not completely satisfied with the one form. Hence the one form may be lost by the other being received. On the other hand the form of a celestial body which entirely fills the potentiality of its matter, so that the latter does not retain the potentiality to another form, is in its subject inseparably. Accordingly the charity of the blessed, because it entirely fills the potentiality of the rational mind, since every actual movement of that mind is directed to God, is possessed by its subject inseparably: whereas the charity of the wayfarer does not so fill the potentiality of its subject, because the latter is not always actually directed to God: so that when it is not actually directed to God, something may occur whereby charity is lost.

It is proper to a habit to incline a power to act, and this belongs to a habit, in so far as it makes whatever is suitable to it, to seem good, and whatever is unsuitable, to seem evil. For as the taste judges of savors according to its disposition, even so does the human mind judge of things to be done, according to its habitual disposition. Hence the Philosopher says (Ethic. iii, 5) that "such as a man is, so does the end appear to him." Accordingly charity is inseparable from its possessor, where that which pertains to charity cannot appear otherwise than good, and that is in heaven, where God is seen in His Essence, which is the very essence of goodness. Therefore the charity of heaven cannot be lost, whereas the charity of the way can, because in this state God is not seen in His Essence, which is the essence of goodness.

I answer that, That one contrary is removed by the other contrary supervening. Now every mortal sin is contrary to charity by its very nature, which consists in man's loving God above all things, and subjecting himself to Him entirely, by referring all that is his to God. It is therefore essential to charity that man should so love God as to wish to submit to Him in all things, and always to follow the rule of His commandments; since whatever is contrary to His commandments is manifestly contrary to charity, and therefore by its very nature is capable of destroying charity.

If indeed charity were an acquired habit dependent on the power of its subject, it would not necessarily be removed by one mortal sin, for act is directly contrary, not to habit but to act. Now the endurance of a habit in its subject does not require the endurance of its act, so that when a contrary act supervenes the acquired habit is not at once done away. But charity, being an infused habit, depends on the action of God Who infuses it, Who stands in relation to the infusion and safekeeping of charity, as the sun does to the diffusion of light in the air, as stated above (A. 10, Obj. 3). Consequently, just as the light would cease at once in the air, were an obstacle placed to its being lit up by the sun, even so charity ceases at once to be in the soul through the placing of an obstacle to the outpouring of charity by God into the soul.

Now it is evident that through every mortal sin which is contrary to God's commandments, an obstacle is placed to the outpouring of charity, since from the very fact that a man chooses to prefer sin to God's friendship, which requires that we should obey His will, it follows that the habit of charity is lost at once through one mortal sin. Hence Augustine says (Gen. ad lit. viii, 12) that "man is enlightened by God's presence, but he is darkened at once by God's absence, because distance from Him is effected not by change of place but by aversion of the will."
