Of the Necessity of Grace

Of the Necessity of Grace — St. Thomas Aquinas asks: Whether without grace man can know any truth?; Whether man can wish or do any good without grace?; Whether by his own natural powers and without grace man can love God above all things?; Whether man without grace and by his own natural powers can fulfil the commandments of the Law?; Whether man can merit everlasting life without grace?; Whether a man, by himself and without the external aid of grace, can prepare himself for grace?; Whether man can rise from sin without the help of grace?; Whether man without grace can avoid sin?; Whether one who has already obtained grace, can, of himself and without further help of grace, do good and avoid sin?; Whether man possessed of grace needs the help of grace in order to persevere?.

We must now consider the exterior principle of human acts, i.e. God, in so far as, through grace, we are helped by Him to do right: and, first, we must consider the grace of God; secondly, its cause; thirdly, its effects.

The first point of consideration will be threefold: for we shall consider (1) The necessity of grace; (2) grace itself, as to its essence; (3) its division.

Under the first head there are ten points of inquiry:

Article 1: Whether without grace man can know any truth?

Augustine says (Retract. i, 4): "I do not approve having said in the prayer, O God, Who dost wish the sinless alone to know the truth; for it may be answered that many who are not sinless know many truths." Now man is cleansed from sin by grace, according to Ps. 50:12: "Create a clean heart in me, O God, and renew a right spirit within my bowels." Therefore without grace man of himself can know truth.

To know truth is a use or act of intellectual light, since, according to the Apostle (Eph. 5:13): "All that is made manifest is light." Now every use implies movement, taking movement broadly, so as to call thinking and willing movements, as is clear from the Philosopher (De Anima iii, 4). Now in corporeal things we see that for movement there is required not merely the form which is the principle of the movement or action, but there is also required the motion of the first mover. Now the first mover in the order of corporeal things is the heavenly body. Hence no matter how perfectly fire has heat, it would not bring about alteration, except by the motion of the heavenly body. But it is clear that as all corporeal movements are reduced to the motion of the heavenly body as to the first corporeal mover, so all movements, both corporeal and spiritual, are reduced to the simple First Mover, Who is God. And hence no matter how perfect a corporeal or spiritual nature is supposed to be, it cannot proceed to its act unless it be moved by God; but this motion is according to the plan of His providence, and not by necessity of nature, as the motion of the heavenly body. Now not only is every motion from God as from the First Mover, but all formal perfection is from Him as from the First Act. And thus the act of the intellect or of any created being whatsoever depends upon God in two ways: first, inasmuch as it is from Him that it has the form whereby it acts; secondly, inasmuch as it is moved by Him to act.

Now every form bestowed on created things by God has power for a determined act, which it can bring about in proportion to its own proper endowment; and beyond which it is powerless, except by a superadded form, as water can only heat when heated by the fire. And thus the human understanding has a form, viz. intelligible light, which of itself is sufficient for knowing certain intelligible things, viz. those we can come to know through the senses. Higher intelligible things of the human intellect cannot know, unless it be perfected by a stronger light, viz. the light of faith or prophecy which is called the "light of grace," inasmuch as it is added to nature.

Hence we must say that for the knowledge of any truth whatsoever man needs Divine help, that the intellect may be moved by God to its act. But he does not need a new light added to his natural light, in order to know the truth in all things, but only in some that surpass his natural knowledge. And yet at times God miraculously instructs some by His grace in things that can be known by natural reason, even as He sometimes brings about miraculously what nature can do.

Article 2: Whether man can wish or do any good without grace?

The Apostle says (Rom. 9:16): "It is not of him that willeth," namely, to will, "nor of him that runneth," namely to run, "but of God that showeth mercy." And Augustine says (De Corrept. et Gratia ii) that "without grace men do nothing good when they either think or wish or love or act."

Man's nature may be looked at in two ways: first, in its integrity, as it was in our first parent before sin; secondly, as it is corrupted in us after the sin of our first parent. Now in both states human nature needs the help of God as First Mover, to do or wish any good whatsoever, as stated above (). But in the state of integrity, as regards the sufficiency of the operative power, man by his natural endowments could wish and do the good proportionate to his nature, such as the good of acquired virtue; but not surpassing good, as the good of infused virtue. But in the state of corrupt nature, man falls short of what he could do by his nature, so that he is unable to fulfil it by his own natural powers. Yet because human nature is not altogether corrupted by sin, so as to be shorn of every natural good, even in the state of corrupted nature it can, by virtue of its natural endowments, work some particular good, as to build dwellings, plant vineyards, and the like; yet it cannot do all the good natural to it, so as to fall short in nothing; just as a sick man can of himself make some movements, yet he cannot be perfectly moved with the movements of one in health, unless by the help of medicine he be cured.

And thus in the state of perfect nature man needs a gratuitous strength superadded to natural strength for one reason, viz. in order to do and wish supernatural good; but for two reasons, in the state of corrupt nature, viz. in order to be healed, and furthermore in order to carry out works of supernatural virtue, which are meritorious. Beyond this, in both states man needs the Divine help, that he may be moved to act well.

Article 3: Whether by his own natural powers and without grace man can love God above all things?

As some maintain, man was first made with only natural endowments; and in this state it is manifest that he loved God to some extent. But he did not love God equally with himself, or less than himself, otherwise he would have sinned. Therefore he loved God above himself. Therefore man, by his natural powers alone, can love God more than himself and above all things.

As was said above (), where the various opinions concerning the natural love of the angels were set forth, man in a state of perfect nature, could by his natural power, do the good natural to him without the addition of any gratuitous gift, though not without the help of God moving him. Now to love God above all things is natural to man and to every nature, not only rational but irrational, and even to inanimate nature according to the manner of love which can belong to each creature. And the reason of this is that it is natural to all to seek and love things according as they are naturally fit (to be sought and loved) since "all things act according as they are naturally fit" as stated in Phys. ii, 8. Now it is manifest that the good of the part is for the good of the whole; hence everything, by its natural appetite and love, loves its own proper good on account of the common good of the whole universe, which is God. Hence Dionysius says (Div. Nom. iv) that "God leads everything to love of Himself." Hence in the state of perfect nature man referred the love of himself and of all other things to the love of God as to its end; and thus he loved God more than himself and above all things. But in the state of corrupt nature man falls short of this in the appetite of his rational will, which, unless it is cured by God's grace, follows its private good, on account of the corruption of nature. And hence we must say that in the state of perfect nature man did not need the gift of grace added to his natural endowments, in order to love God above all things naturally, although he needed God's help to move him to it; but in the state of corrupt nature man needs, even for this, the help of grace to heal his nature.

Article 4: Whether man without grace and by his own natural powers can fulfil the commandments of the Law?

Augustine says (De Haeres. lxxxviii) that it is part of the Pelagian heresy that "they believe that without grace man can fulfil all the Divine commandments."

There are two ways of fulfilling the commandments of the Law. The first regards the substance of the works, as when a man does works of justice, fortitude, and of other virtues. And in this way man in the state of perfect nature could fulfil all the commandments of the Law; otherwise he would have been unable to sin in that state, since to sin is nothing else than to transgress the Divine commandments. But in the state of corrupted nature man cannot fulfil all the Divine commandments without healing grace. Secondly, the commandments of the law can be fulfilled, not merely as regards the substance of the act, but also as regards the mode of acting, i.e. their being done out of charity. And in this way, neither in the state of perfect nature, nor in the state of corrupt nature can man fulfil the commandments of the law without grace. Hence, Augustine (De Corrupt. et Grat. ii) having stated that "without grace men can do no good whatever," adds: "Not only do they know by its light what to do, but by its help they do lovingly what they know." Beyond this, in both states they need the help of God's motion in order to fulfil the commandments, as stated above ().

Article 5: Whether man can merit everlasting life without grace?

The Apostle says (Rom. 6:23): "The grace of God is life everlasting." And as a gloss says, this is said "that we may understand that God, of His own mercy, leads us to everlasting life."

Acts conducing to an end must be proportioned to the end. But no act exceeds the proportion of its active principle; and hence we see in natural things, that nothing can by its operation bring about an effect which exceeds its active force, but only such as is proportionate to its power. Now everlasting life is an end exceeding the proportion of human nature, as is clear from what we have said above (). Hence man, by his natural endowments, cannot produce meritorious works proportionate to everlasting life; and for this a higher force is needed, viz. the force of grace. And thus without grace man cannot merit everlasting life; yet he can perform works conducing to a good which is natural to man, as "to toil in the fields, to drink, to eat, or to have friends," and the like, as Augustine says in his third Reply to the Pelagians [*Hypognosticon iii, among the spurious works of St. Augustine].

Article 6: Whether a man, by himself and without the external aid of grace, can prepare himself for grace?

It is written (Jn. 6:44): "No man can come to Me except the Father, Who hath sent Me, draw him." But if man could prepare himself, he would not need to be drawn by another. Hence man cannot prepare himself without the help of grace.

The preparation of the human will for good is twofold: the first, whereby it is prepared to operate rightly and to enjoy God; and this preparation of the will cannot take place without the habitual gift of grace, which is the principle of meritorious works, as stated above (). There is a second way in which the human will may be taken to be prepared for the gift of habitual grace itself. Now in order that man prepare himself to receive this gift, it is not necessary to presuppose any further habitual gift in the soul, otherwise we should go on to infinity. But we must presuppose a gratuitous gift of God, Who moves the soul inwardly or inspires the good wish. For in these two ways do we need the Divine assistance, as stated above (). Now that we need the help of God to move us, is manifest. For since every agent acts for an end, every cause must direct is effect to its end, and hence since the order of ends is according to the order of agents or movers, man must be directed to the last end by the motion of the first mover, and to the proximate end by the motion of any of the subordinate movers; as the spirit of the soldier is bent towards seeking the victory by the motion of the leader of the army---and towards following the standard of a regiment by the motion of the standard-bearer. And thus since God is the First Mover, simply, it is by His motion that everything seeks to be likened to God in its own way. Hence Dionysius says (Div. Nom. iv) that "God turns all to Himself." But He directs righteous men to Himself as to a special end, which they seek, and to which they wish to cling, according to Ps. 72:28, "it is good for Me to adhere to my God." And that they are "turned" to God can only spring from God's having "turned" them. Now to prepare oneself for grace is, as it were, to be turned to God; just as, whoever has his eyes turned away from the light of the sun, prepares himself to receive the sun's light, by turning his eyes towards the sun. Hence it is clear that man cannot prepare himself to receive the light of grace except by the gratuitous help of God moving him inwardly.

Article 7: Whether man can rise from sin without the help of grace?

The Apostle says (Gal. 2:21; Cf. Gal. 3:21): "For if there had been a law given which could give life---then Christ died in vain," i.e. to no purpose. Hence with equal reason, if man has a nature, whereby he can he justified, "Christ died in vain," i.e. to no purpose. But this cannot fittingly be said. Therefore by himself he cannot be justified, i.e. he cannot return from a state of sin to a state of justice.

Man by himself can no wise rise from sin without the help of grace. For since sin is transient as to the act and abiding in its guilt, as stated above (), to rise from sin is not the same as to cease the act of sin; but to rise from sin means that man has restored to him what he lost by sinning. Now man incurs a triple loss by sinning, as was clearly shown above (; ; ), viz. stain, corruption of natural good, and debt of punishment. He incurs a stain, inasmuch as he forfeits the lustre of grace through the deformity of sin. Natural good is corrupted, inasmuch as man's nature is disordered by man's will not being subject to God's; and this order being overthrown, the consequence is that the whole nature of sinful man remains disordered. Lastly, there is the debt of punishment, inasmuch as by sinning man deserves everlasting damnation.

Now it is manifest that none of these three can be restored except by God. For since the lustre of grace springs from the shedding of Divine light, this lustre cannot be brought back, except God sheds His light anew: hence a habitual gift is necessary, and this is the light of grace. Likewise, the order of nature can only be restored, i.e. man's will can only be subject to God when God draws man's will to Himself, as stated above (). So, too, the guilt of eternal punishment can be remitted by God alone, against Whom the offense was committed and Who is man's Judge. And thus in order that man rise from sin there is required the help of grace, both as regards a habitual gift, and as regards the internal motion of God.

Article 8: Whether man without grace can avoid sin?

Augustine says (De Perfect Just. xxi): "Whoever denies that we ought to say the prayer 'Lead us not into temptation' (and they deny it who maintain that the help of God's grace is not necessary to man for salvation, but that the gift of the law is enough for the human will) ought without doubt to be removed beyond all hearing, and to be anathematized by the tongues of all."

We may speak of man in two ways: first, in the state of perfect nature; secondly, in the state of corrupted nature. Now in the state of perfect nature, man, without habitual grace, could avoid sinning either mortally or venially; since to sin is nothing else than to stray from what is according to our nature---and in the state of perfect nature man could avoid this. Nevertheless he could not have done it without God's help to uphold him in good, since if this had been withdrawn, even his nature would have fallen back into nothingness.

But in the state of corrupt nature man needs grace to heal his nature in order that he may entirely abstain from sin. And in the present life this healing is wrought in the mind---the carnal appetite being not yet restored. Hence the Apostle (Rom. 7:25) says in the person of one who is restored: "I myself, with the mind, serve the law of God, but with the flesh, the law of sin." And in this state man can abstain from all mortal sin, which takes its stand in his reason, as stated above (); but man cannot abstain from all venial sin on account of the corruption of his lower appetite of sensuality. For man can, indeed, repress each of its movements (and hence they are sinful and voluntary), but not all, because whilst he is resisting one, another may arise, and also because the reason is always alert to avoid these movements, as was said above ().

So, too, before man's reason, wherein is mortal sin, is restored by justifying grace, he can avoid each mortal sin, and for a time, since it is not necessary that he should be always actually sinning. But it cannot be that he remains for a long time without mortal sin. Hence Gregory says (Super Ezech. Hom. xi) that " a sin not at once taken away by repentance, by its weight drags us down to other sins": and this because, as the lower appetite ought to be subject to the reason, so should the reason be subject to God, and should place in Him the end of its will. Now it is by the end that all human acts ought to be regulated, even as it is by the judgment of the reason that the movements of the lower appetite should be regulated. And thus, even as inordinate movements of the sensitive appetite cannot help occurring since the lower appetite is not subject to reason, so likewise, since man's reason is not entirely subject to God, the consequence is that many disorders occur in the reason. For when man's heart is not so fixed on God as to be unwilling to be parted from Him for the sake of finding any good or avoiding any evil, many things happen for the achieving or avoiding of which a man strays from God and breaks His commandments, and thus sins mortally: especially since, when surprised, a man acts according to his preconceived end and his pre-existing habits, as the Philosopher says (Ethic. iii); although with premeditation of his reason a man may do something outside the order of his preconceived end and the inclination of his habit. But because a man cannot always have this premeditation, it cannot help occurring that he acts in accordance with his will turned aside from God, unless, by grace, he is quickly brought back to the due order.

Article 9: Whether one who has already obtained grace, can, of himself and without further help of grace, do good and avoid sin?

Augustine says (De Natura et Gratia xxvi) that "as the eye of the body though most healthy cannot see unless it is helped by the brightness of light, so, neither can a man, even if he is most righteous, live righteously unless he be helped by the eternal light of justice." But justification is by grace, according to Rom. 3:24: "Being justified freely by His grace." Hence even a man who already possesses grace needs a further assistance of grace in order to live righteously.

As stated above (), in order to live righteously a man needs a twofold help of God---first, a habitual gift whereby corrupted human nature is healed, and after being healed is lifted up so as to work deeds meritoriously of everlasting life, which exceed the capability of nature. Secondly, man needs the help of grace in order to be moved by God to act.

Now with regard to the first kind of help, man does not need a further help of grace, e.g. a further infused habit. Yet he needs the help of grace in another way, i.e. in order to be moved by God to act righteously, and this for two reasons: first, for the general reason that no created thing can put forth any act, unless by virtue of the Divine motion. Secondly, for this special reason---the condition of the state of human nature. For although healed by grace as to the mind, yet it remains corrupted and poisoned in the flesh, whereby it serves "the law of sin," Rom. 7:25. In the intellect, too, there seems the darkness of ignorance, whereby, as is written (Rom. 8:26): "We know not what we should pray for as we ought"; since on account of the various turns of circumstances, and because we do not know ourselves perfectly, we cannot fully know what is for our good, according to Wis. 9:14: "For the thoughts of mortal men are fearful and our counsels uncertain." Hence we must be guided and guarded by God, Who knows and can do all things. For which reason also it is becoming in those who have been born again as sons of God, to say: "Lead us not into temptation," and "Thy Will be done on earth as it is in heaven," and whatever else is contained in the Lord's Prayer pertaining to this.

Article 10: Whether man possessed of grace needs the help of grace in order to persevere?

Augustine says (De Persev. ii): "Why is perseverance besought of God, if it is not bestowed by God? For is it not a mocking request to seek what we know He does not give, and what is in our power without His giving it?" Now perseverance is besought by even those who are hallowed by grace; and this is seen, when we say "Hallowed be Thy name," which Augustine confirms by the words of Cyprian (De Correp. et Grat. xii). Hence man, even when possessed of grace, needs perseverance to be given to him by God.

Perseverance is taken in three ways. First, to signify a habit of the mind whereby a man stands steadfastly, lest he be moved by the assault of sadness from what is virtuous. And thus perseverance is to sadness as continence is to concupiscence and pleasure, as the Philosopher says (Ethic. vii, 7). Secondly, perseverance may be called a habit, whereby a man has the purpose of persevering in good unto the end. And in both these ways perseverance is infused together with grace, even as continence and the other virtues are. Thirdly, perseverance is called the abiding in good to the end of life. And in order to have this perseverance man does not, indeed, need another habitual grace, but he needs the Divine assistance guiding and guarding him against the attacks of the passions, as appears from the preceding article. And hence after anyone has been justified by grace, he still needs to beseech God for the aforesaid gift of perseverance, that he may be kept from evil till the end of his life. For to many grace is given to whom perseverance in grace is not given.
