Summa Th. I-II EN Qu.65
We must now consider the connection of virtues: under which head there are five points of inquiry:
(1) Whether the moral virtues are connected with one another?
(2) Whether the moral virtues can be without charity?
(3) Whether charity can be without them?
(4) Whether faith and hope can be without charity?
(5) Whether charity can be without them?
Objection: 1. It would seem that the moral virtues are not connected with one another. Because moral virtues are sometimes caused by the exercise of acts, as is proved in Ethic. ii, 1,2. But man can exercise himself in the acts of one virtue, without exercising himself in the acts of some other virtue. Therefore it is possible to have one moral virtue without another.
2. Further, magnificence and magnanimity are moral virtues. Now a man may have other moral virtues without having magnificence or magnanimity: for the Philosopher says (Ethic. iv, 2,3) that "a poor man cannot be magnificent," and yet he may have other virtues; and (Ethic. iv) that "he who is worthy of small things, and so accounts his worth, is modest, but not magnanimous." Therefore the moral virtues are not connected with one another.
3. Further, as the moral virtues perfect the appetitive part of the soul, so do the intellectual virtues perfect the intellective part. But the intellectual virtues are not mutually connected: since we may have one science, without having another. Neither, therefore, are the moral virtues connected with one another.
4. Further, if the moral virtues are mutually connected, this can only be because they are united together in prudence. But this does not suffice to connect the moral virtues together. For, seemingly, one may be prudent about things to be done in relation to one virtue, without being prudent in those that concern another virtue: even as one may have the art of making certain things, without the art of making certain others. Now prudence is right reason about things to be done. Therefore the moral virtues are not necessarily connected with one another.
On the contrary Ambrose says on Lc 6,20: "The virtues are connected and linked together, so that whoever has one, is seen to have several": and Augustine says (De Trin. vi, 4) that "the virtues that reside in the human mind are quite inseparable from one another": and Gregory says (Moral. xxii, 1) that "one virtue without the other is either of no account whatever, or very imperfect": and Cicero says (Quaest. Tusc. ii): "If you confess to not having one particular virtue, it must needs be that you have none at all."
I answer that Moral virtue may be considered either as perfect or as imperfect. An imperfect moral virtue, temperance for instance, or fortitude, is nothing but an inclination in us to do some kind of good deed, whether such inclination be in us by nature or by habituation. If we take the moral virtues in this way, they are not connected: since we find men who, by natural temperament or by being accustomed, are prompt in doing deeds of liberality, but are not prompt in doing deeds of chastity.But the perfect moral virtue is a habit that inclines us to do a good deed well; and if we take moral virtues in this way, we must say that they are connected, as nearly as all are agreed in saying. For this two reasons are given, corresponding to the different ways of assigning the distinction of the cardinal virtues. For, as we stated above (Question , Articles ,4), some distinguish them according to certain general properties of the virtues: for instance, by saying that discretion belongs to prudence, rectitude to justice, moderation to temperance, and strength of mind to fortitude, in whatever matter we consider these properties to be. In this way the reason for the connection is evident: for strength of mind is not commended as virtuous, if it be without moderation or rectitude or discretion: and so forth. This, too, is the reason assigned for the connection by Gregory, who says (Moral. xxii, 1) that "a virtue cannot be perfect" as a virtue, "if isolated from the others: for there can be no true prudence without temperance, justice and fortitude": and he continues to speak in like manner of the other virtues (cf. Question , Article , Objection ). Augustine also gives the same reason (De Trin. vi, 4).Others, however, differentiate these virtues in respect of their matters, and it is in this way that Aristotle assigns the reason for their connection (Ethic. vi, 13). Because, as stated above (Question , Article ), no moral virtue can be without prudence; since it is proper to moral virtue to make a right choice, for it is an elective habit. Now right choice requires not only the inclination to a due end, which inclination is the direct outcome of moral virtue, but also correct choice of things conducive to the end, which choice is made by prudence, that counsels, judges, and commands in those things that are directed to the end. In like manner one cannot have prudence unless one has the moral virtues: since prudence is "right reason about things to be done," and the starting point of reason is the end of the thing to be done, to which end man is rightly disposed by moral virtue. Hence, just as we cannot have speculative science unless we have the understanding of the principles, so neither can we have prudence without the moral virtues: and from this it follows clearly that the moral virtues are connected with one another.
Reply to Objection: 1. Some moral virtues perfect man as regards his general state, in other words, with regard to those things which have to be done in every kind of human life. Hence man needs to exercise himself at the same time in the matters of all moral virtues. And if he exercise himself, by good deeds, in all such matters, he will acquire the habits of all the moral virtues. But if he exercise himself by good deeds in regard to one matter, but not in regard to another, for instance, by behaving well in matters of anger, but not in matters of concupiscence; he will indeed acquire a certain habit of restraining his anger; but this habit will lack the nature of virtue, through the absence of prudence, which is wanting in matters of concupiscence. In the same way, natural inclinations fail to have the complete character of virtue, if prudence be lacking.But there are some moral virtues which perfect man with regard to some eminent state, such as magnificence and magnanimity; and since it does not happen to all in common to be exercised in the matter of such virtues, it is possible for a man to have the other moral virtues, without actually having the habits of these virtues---provided we speak of acquired virtue. Nevertheless, when once a man has acquired those other virtues he possesses these in proximate potentiality. Because when, by practice, a man has acquired liberality in small gifts and expenditure, if he were to come in for a large sum of money, he would acquire the habit of magnificence with but little practice: even as a geometrician, by dint of little study, acquires scientific knowledge about some conclusion which had never been presented to his mind before. Now we speak of having a thing when we are on the point of having it, according to the saying of the Philosopher (Phys. ii, text. 56): "That which is scarcely lacking is not lacking at all."
2. This suffices for the Reply to the Second Objection.
3. The intellectual virtues are about divers matters having no relation to one another, as is clearly the case with the various sciences and arts. Hence we do not observe in them the connection that is to be found among the moral virtues, which are about passions and operations, that are clearly related to one another. For all the passions have their rise in certain initial passions, viz. love and hatred, and terminate in certain others, viz. pleasure and sorrow. In like manner all the operations that are the matter of moral virtue are related to one another, and to the passions. Hence the whole matter of moral virtues falls under the one rule of prudence.Nevertheless, all intelligible things are related to first principles. And in this way, all the intellectual virtues depend on the understanding of principles; even as prudence depends on the moral virtues, as stated. On the other hand, the universal principles which are the object of the virtue of understanding of principles, do not depend on the conclusions, which are the objects of the other intellectual virtues, as do the moral virtues depend on prudence, because the appetite, in a fashion, moves the reason, and the reason the appetite, as stated above (Question , Article ; Question , Article , ad 1).
4. Those things to which the moral virtues incline, are as the principles of prudence: whereas the products of art are not the principles, but the matter of art. Now it is evident that, though reason may be right in one part of the matter, and not in another, yet in no way can it be called right reason, if it be deficient in any principle whatever. Thus, if a man be wrong about the principle, "A whole is greater than its part," he cannot acquire the science of geometry, because he must necessarily wander from the truth in his conclusion. Moreover, things "done" are related to one another, but not things "made," as stated above (ad 3). Consequently the lack of prudence in one department of things to be done, would result in a deficiency affecting other things to be done: whereas this does not occur in things to be made.
Objection: 1. It would seem that moral virtues can be without charity. For it is stated in the Liber Sentent. Prosperi vii, that "every virtue save charity may be common to the good and bad." But "charity can be in none except the good," as stated in the same book. Therefore the other virtues can be had without charity.
2. Further, moral virtues can be acquired by means of human acts, as stated in Ethic. ii, 1,2, whereas charity cannot be had otherwise than by infusion, according to Rm 5,5: "The charity of God is poured forth in our hearts by the Holy Ghost Who is given to us." Therefore it is possible to have the other virtues without charity.
3. Further, the moral virtues are connected together, through depending on prudence. But charity does not depend on prudence; indeed, it surpasses prudence, according to Ep 3,19: "The charity of Christ, which surpasseth all knowledge." Therefore the moral virtues are not connected with charity, and can be without it.
On the contrary It is written (1Jn 3,14): "He that loveth not, abideth in death." Now the spiritual life is perfected by the virtues, since it is "by them" that "we lead a good life," as Augustine states (De Lib. Arb. ii, 17,19). Therefore they cannot be without the love of charity.
I answer that As stated above (Question , Article ), it is possible by means of human works to acquire moral virtues, in so far as they produce good works that are directed to an end not surpassing the natural power of man: and when they are acquired thus, they can be without charity, even as they were in many of the Gentiles. But in so far as they produce good works in proportion to a supernatural last end, thus they have the character of virtue, truly and perfectly; and cannot be acquired by human acts, but are infused by God. Such like moral virtues cannot be without charity. For it has been stated above (Article ; Question , Articles ,5) that the other moral virtues cannot be without prudence; and that prudence cannot be without the moral virtues, because these latter make man well disposed to certain ends, which are the starting-point of the procedure of prudence. Now for prudence to proceed aright, it is much more necessary that man be well disposed towards his ultimate end, which is the effect of charity, than that he be well disposed in respect of other ends, which is the effect of moral virtue: just as in speculative matters right reason has greatest need of the first indemonstrable principle, that "contradictories cannot both be true at the same time." It is therefore evident that neither can infused prudence be without charity; nor, consequently, the other moral virtues, since they cannot be without prudence.It is therefore clear from what has been said that only the infused virtues are perfect, and deserve to be called virtues simply: since they direct man well to the ultimate end. But the other virtues, those, namely, that are acquired, are virtues in a restricted sense, but not simply: for they direct man well in respect of the last end in some particular genus of action, but not in respect of the last end simply. Hence a gloss of Augustine [*Cf. Lib. Sentent. Prosperi cvi.] on the words, "All that is not of faith is sin" (Rm 14,23), says: "He that fails to acknowledge the truth, has no true virtue, even if his conduct be good."
Reply to Objection: 1. Virtue, in the words quoted, denotes imperfect virtue. Else if we take moral virtue in its perfect state, "it makes its possessor good," and consequently cannot be in the wicked.
2. This argument holds good of virtue in the sense of acquired virtue.
3. Though charity surpasses science and prudence, yet prudence depends on charity, as stated: and consequently so do all the infused moral virtues.
Objection: 1. It would seem possible to have charity without the moral virtues. For when one thing suffices for a certain purpose, it is superfluous to employ others. Now charity alone suffices for the fulfilment of all the works of virtue, as is clear from 1Co 13,4, seqq.: "Charity is patient, is kind," etc. Therefore it seems that if one has charity, other virtues are superfluous.
2. Further, he that has a habit of virtue easily performs the works of that virtue, and those works are pleasing to him for their own sake: hence "pleasure taken in a work is a sign of habit" (Ethic. ii, 3). Now many have charity, being free from mortal sin, and yet they find it difficult to do works of virtue; nor are these works pleasing to them for their own sake, but only for the sake of charity. Therefore many have charity without the other virtues.
3. Further, charity is to be found in every saint: and yet there are some saints who are without certain virtues. For Bede says (on Lc 17,10) that the saints are more humbled on account of their not having certain virtues, than rejoiced at the virtues they have. Therefore, if a man has charity, it does not follow of necessity that he has all the moral virtues.
On the contrary The whole Law is fulfilled through charity, for it is written (Rm 13,8): "He that loveth his neighbor, hath fulfilled the Law." Now it is not possible to fulfil the whole Law, without having all the moral virtues: since the law contains precepts about all acts of virtue, as stated in Ethic. v, 1,2. Therefore he that has charity, has all the moral virtues. Moreover, Augustine says in a letter (Epis. clxvii) [*Cf. Serm. xxxix and xlvi de Temp.] that charity contains all the cardinal virtues.
I answer that All the moral virtues are infused together with charity. The reason for this is that God operates no less perfectly in works of grace than in works of nature. Now, in the works of nature, we find that whenever a thing contains a principle of certain works, it has also whatever is necessary for their execution: thus animals are provided with organs whereby to perform the actions that their souls empower them to do. Now it is evident that charity, inasmuch as it directs man to his last end, is the principle of all the good works that are referable to his last end. Wherefore all the moral virtues must needs be infused together with charity, since it is through them that man performs each different kind of good work.It is therefore clear that the infused moral virtues are connected, not only through prudence, but also on account of charity: and, again, that whoever loses charity through mortal sin, forfeits all the infused moral virtues.
Reply to Objection: 1. In order that the act of a lower power be perfect, not only must there be perfection in the higher, but also in the lower power: for if the principal agent were well disposed, perfect action would not follow, if the instrument also were not well disposed. Consequently, in order that man work well in things referred to the end, he needs not only a virtue disposing him well to the end, but also those virtues which dispose him well to whatever is referred to the end: for the virtue which regards the end is the chief and moving principle in respect of those things that are referred to the end. Therefore it is necessary to have the moral virtues together with charity.
2. It happens sometimes that a man who has a habit, finds it difficult to act in accordance with the habit, and consequently feels no pleasure and complacency in the act, on account of some impediment supervening from without: thus a man who has a habit of science, finds it difficult to understand, through being sleepy or unwell. In like manner sometimes the habits of moral virtue experience difficulty in their works, by reason of certain ordinary dispositions remaining from previous acts. This difficulty does not occur in respect of acquired moral virtue: because the repeated acts by which they are acquired, remove also the contrary dispositions.
3. Certain saints are said not to have certain virtues, in so far as they experience difficulty in the acts of those virtues, for the reason stated; although they have the habits of all the virtues.
Objection: 1. It would seem that faith and hope are never without charity. Because, since they are theological virtues, they seem to be more excellent than even the infused moral virtues. But the infused moral virtues cannot be without charity. Neither therefore can faith and hope be without charity.
2. Further, "no man believes unwillingly" as Augustine says (Tract. xxvi in Joan.). But charity is in the will as a perfection thereof, as stated above (Question , Article ). Therefore faith cannot be without charity.
3. Further, Augustine says (Enchiridion viii) that "there can be no hope without love." But love is charity: for it is of this love that he speaks. Therefore hope cannot be without charity.
On the contrary A gloss on Mt 1,2 says that "faith begets hope, and hope, charity." Now the begetter precedes the begotten, and can be without it. Therefore faith can be without hope; and hope, without charity.
I answer that Faith and hope, like the moral virtues, can be considered in two ways; first in an inchoate state; secondly, as complete virtues. For since virtue is directed to the doing of good works, perfect virtue is that which gives the faculty of doing a perfectly good work, and this consists in not only doing what is good, but also in doing it well. Else, if what is done is good, but not well done, it will not be perfectly good; wherefore neither will the habit that is the principle of such an act, have the perfect character of virtue. For instance, if a man do what is just, what he does is good: but it will not be the work of a perfect virtue unless he do it well, i.e. by choosing rightly, which is the result of prudence; for which reason justice cannot be a perfect virtue without prudence.Accordingly faith and hope can exist indeed in a fashion without charity: but they have not the perfect character of virtue without charity. For, since the act of faith is to believe in God; and since to believe is to assent to someone of one's own free will: to will not as one ought, will not be a perfect act of faith. To will as one ought is the outcome of charity which perfects the will: since every right movement of the will proceeds from a right love, as Augustine says (De Civ. Dei xiv, 9). Hence faith may be without charity, but not as a perfect virtue: just as temperance and fortitude can be without prudence. The same applies to hope. Because the act of hope consists in looking to God for future bliss. This act is perfect, if it is based on the merits which we have; and this cannot be without charity. But to expect future bliss through merits which one has not yet, but which one proposes to acquire at some future time, will be an imperfect act; and this is possible without charity. Consequently, faith and hope can be without charity; yet, without charity, they are not virtues properly so-called; because the nature of virtue requires that by it, we should not only do what is good, but also that we should do it well (Ethic. ii, 6).
Reply to Objection: 1. Moral virtue depends on prudence: and not even infused prudence has the character of prudence without charity; for this involves the absence of due order to the first principle, viz. the ultimate end. On the other hand faith and hope, as such, do not depend either on prudence or charity; so that they can be without charity, although they are not virtues without charity, as stated.
2. This argument is true of faith considered as a perfect virtue.
3. Augustine is speaking here of that hope whereby we look to gain future bliss through merits which we have already; and this is not without charity.
Objection: 1. It would seem that charity can be without faith and hope. For charity is the love of God. But it is possible for us to love God naturally, without already having faith, or hope in future bliss. Therefore charity can be without faith and hope.
2. Further, charity is the root of all the virtues, according to Ep 3,17: "Rooted and founded in charity." Now the root is sometimes without branches. Therefore charity can sometimes be without faith and hope, and the other virtues.
3. Further, there was perfect charity in Christ. And yet He had neither faith nor hope: because He was a perfect comprehensor, as we shall explain further on (III 7,3 III 7,4). Therefore charity can be without faith and hope.
On the contrary The Apostle says (He 11,6): "Without faith it is impossible to please God"; and this evidently belongs most to charity, according to Pr 8,17: "I love them that love me." Again, it is by hope that we are brought to charity, as stated above (Question , Article ). Therefore it is not possible to have charity without faith and hope.
I answer that Charity signifies not only the love of God, but also a certain friendship with Him; which implies, besides love, a certain mutual return of love, together with mutual communion, as stated in Ethic. viii, 2. That this belongs to charity is evident from 1Jn 4,16: "He that abideth in charity, abideth in God, and God in him," and from 1Co 1,9, where it is written: "God is faithful, by Whom you are called unto the fellowship of His Son." Now this fellowship of man with God, which consists in a certain familiar colloquy with Him, is begun here, in this life, by grace, but will be perfected in the future life, by glory; each of which things we hold by faith and hope. Wherefore just as friendship with a person would be impossible, if one disbelieved in, or despaired of, the possibility of their fellowship or familiar colloquy; so too, friendship with God, which is charity, is impossible without faith, so as to believe in this fellowship and colloquy with God, and to hope to attain to this fellowship. Therefore charity is quite impossible without faith and hope.
Reply to Objection: 1. Charity is not any kind of love of God, but that love of God, by which He is loved as the object of bliss, to which object we are directed by faith and hope.
2. Charity is the root of faith and hope, in so far as it gives them the perfection of virtue. But faith and hope as such are the precursors of charity, as stated above (Question , Article ), and so charity is impossible without them.
3. In Christ there was neither faith nor hope, on account of their implying an imperfection. But instead of faith, He had manifest vision, and instead of hope, full comprehension [*See above, Question , Article ]: so that in Him was perfect charity.
We must now consider equality among the virtues: under which head there are six points of inquiry:
(1) Whether one virtue can be greater or less than another?
(2) Whether all the virtues existing together in one subject are equal?
(3) Of moral virtue in comparison with intellectual virtue;
(4) Of the moral virtues as compared with one another;
(5) Of the intellectual virtues in comparison with one another;
(6) Of the theological virtues in comparison with one another.
Objection: 1. It would seem that one virtue cannot be greater or less than another. For it is written (Ap 21,16) that the sides of the city of Jerusalem are equal; and a gloss says that the sides denote the virtues. Therefore all virtues are equal; and consequently one cannot be greater than another.
2. Further, a thing that, by its nature, consists in a maximum, cannot be more or less. Now the nature of virtue consists in a maximum, for virtue is "the limit of power," as the Philosopher states (De Coelo i, text. 116); and Augustine says (De Lib. Arb. ii, 19) that "virtues are very great boons, and no one can use them to evil purpose." Therefore it seems that one virtue cannot be greater or less than another.
3. Further, the quantity of an effect is measured by the power of the agent. But perfect, viz. infused virtues, are from God Whose power is uniform and infinite. Therefore it seems that one virtue cannot be greater than another.
On the contrary Wherever there can be increase and greater abundance, there can be inequality. Now virtues admit of greater abundance and increase: for it is written (Mt 5,20): "Unless your justice abound more than that of the Scribes and Pharisees, you shall not enter into the kingdom of heaven": and (Pr 15,5): "In abundant justice there is the greatest strength [virtus]." Therefore it seems that a virtue can be greater or less than another.
I answer that When it is asked whether one virtue can be greater than another, the question can be taken in two senses. First, as applying to virtues of different species. In this sense it is clear that one virtue is greater than another; since a cause is always more excellent than its effect; and among effects, those nearest to the cause are the most excellent. Now it is clear from what has been said (Question , Article ; Question , Article ) that the cause and root of human good is the reason. Hence prudence which perfects the reason, surpasses in goodness the other moral virtues which perfect the appetitive power, in so far as it partakes of reason. And among these, one is better than another, according as it approaches nearer to the reason. Consequently justice, which is in the will, excels the remaining moral virtues; and fortitude, which is in the irascible part, stands before temperance, which is in the concupiscible, which has a smaller share of reason, as stated in Ethic. vii, 6.The question can be taken in another way, as referring to virtues of the same species. In this way, according to what was said above (Question , Article ), when we were treating of the intensity of habits, virtue may be said to be greater or less in two ways: first, in itself; secondly with regard to the subject that partakes of it. If we consider it in itself, we shall call it greater or little, according to the things to which it extends. Now whosoever has a virtue, e.g. temperance, has it in respect of whatever temperance extends to. But this does not apply to science and art: for every grammarian does not know everything relating to grammar. And in this sense the Stoics said rightly, as Simplicius states in his Commentary on the Predicaments, that virtue cannot be more or less, as science and art can; because the nature of virtue consists in a maximum.If, however, we consider virtue on the part of the subject, it may then be greater or less, either in relation to different times, or in different men. Because one man is better disposed than another to attain to the mean of virtue which is defined by right reason; and this, on account of either greater habituation, or a better natural disposition, or a more discerning judgment of reason, or again a greater gift of grace, which is given to each one "according to the measure of the giving of Christ," as stated in Ep 4,9. And here the Stoics erred, for they held that no man should be deemed virtuous, unless he were, in the highest degree, disposed to virtue. Because the nature of virtue does not require that man should reach the mean of right reason as though it were an indivisible point, as the Stoics thought; but it is enough that he should approach the mean, as stated in Ethic. ii, 6. Moreover, one same indivisible mark is reached more nearly and more readily by one than by another: as may be seen when several arches aim at a fixed target.
Reply to Objection: 1. This equality is not one of absolute quantity, but of proportion: because all virtues grow in a man proportionately, as we shall see further on (Article ).
2. This "limit" which belongs to virtue, can have the character of something "more" or "less" good, in the ways explained above: since, as stated, it is not an indivisible limit.
3. God does not work by necessity of nature, but according to the order of His wisdom, whereby He bestows on men various measures of virtue, according to Ep 4,7: "To every one of you [Vulg.: 'us'] is given grace according to the measure of the giving of Christ."
Objection: 1. It would seem that the virtues in one same man are not all equally intense. For the Apostle says (1Co 7,7): "Everyone hath his proper gift from God; one after this manner, and another after that." Now one gift would not be more proper than another to a man, if God infused all the virtues equally into each man. Therefore it seems that the virtues are not all equal in one and the same man.
2. Further, if all the virtues were equally intense in one and the same man, it would follow that whoever surpasses another in one virtue, would surpass him in all the others. But this is clearly not the case: since various saints are specially praised for different virtues; e.g. Abraham for faith (Rm 4), Moses for his meekness (Nb 7,3), Job for his patience (Tb 2,12). This is why of each Confessor the Church sings: "There was not found his like in keeping the law of the most High," [*See Lesson in the Mass Statuit (Dominican Missal)], since each one was remarkable for some virtue or other. Therefore the virtues are not all equal in one and the same man.
3. Further, the more intense a habit is, the greater one's pleasure and readiness in making use of it. Now experience shows that a man is more pleased and ready to make use of one virtue than of another. Therefore the virtues are not all equal in one and the same man.
On the contrary Augustine says (De Trin. vi, 4) that "those who are equal in fortitude are equal in prudence and temperance," and so on. Now it would not be so, unless all the virtues in one man were equal. Therefore all virtues are equal in one man.
I answer that As explained above (Article ), the comparative greatness of virtues can be understood in two ways. First, as referring to their specific nature: and in this way there is no doubt that in a man one virtue is greater than another, for example, charity, than faith and hope. Secondly, it may be taken as referring to the degree of participation by the subject, according as a virtue becomes intense or remiss in its subject. In this sense all the virtues in one man are equal with an equality of proportion, in so far as their growth in man is equal: thus the fingers are unequal in size, but equal in proportion, since they grow in proportion to one another.Now the nature of this equality is to be explained in the same way as the connection of virtues; for equality among virtues is their connection as to greatness. Now it has been stated above (Question , Article ) that a twofold connection of virtues may be assigned. The first is according to the opinion of those who understood these four virtues to be four general properties of virtues, each of which is found together with the other in any matter. In this way virtues cannot be said to be equal in any matter unless they have all these properties equal. Augustine alludes to this kind of equality (De Trin. vi, 4) when he says: "If you say these men are equal in fortitude, but that one is more prudent than the other; it follows that the fortitude of the latter is less prudent. Consequently they are not really equal in fortitude, since the former's fortitude is more prudent. You will find that this applies to the other virtues if you run over them all in the same way."The other kind of connection among virtues followed the opinion of those who hold these virtues to have their own proper respective matters (Question , Articles ,2). In this way the connection among moral virtues results from prudence, and, as to the infused virtues, from charity, and not from the inclination, which is on the part of the subject, as stated above (Question , Article ). Accordingly the nature of the equality among virtues can also be considered on the part of prudence, in regard to that which is formal in all the moral virtues: for in one and the same man, so long as his reason has the same degree of perfection, the mean will be proportionately defined according to right reason in each matter of virtue.But in regard to that which is material in the moral virtues, viz. the inclination to the virtuous act, one may be readier to perform the act of one virtue, than the act of another virtue, and this either from nature, or from habituation, or again by the grace of God.
Reply to Objection: 1. This saying of the Apostle may be taken to refer to the gifts of gratuitous grace, which are not common to all, nor are all of them equal in the one same subject. We might also say that it refers to the measure of sanctifying grace, by reason of which one man has all the virtues in greater abundance than another man, on account of his greater abundance of prudence, or also of charity, in which all the infused virtues are connected.
2. One saint is praised chiefly for one virtue, another saint for another virtue, on account of his more admirable readiness for the act of one virtue than for the act of another virtue.
3. This suffices for the Reply to the Third Objection.
Summa Th. I-II EN Qu.65
