Summa Theologica

Objection 1: It would seem that the fulness of grace is not proper to Christ. For what is proper to anyone belongs to him alone. But to be full of grace is attributed to some others; for it was said to the Blessed Virgin (Lk. 1:28): "Hail, full of grace"; and again it is written (Acts 6:8): "Stephen, full of grace and fortitude." Therefore the fulness of grace is not proper to Christ.

Objection 2: Further, what can be communicated to others through Christ does not seem to be proper to Christ. But the fulness of grace can be communicated to others through Christ, since the Apostle says (Eph. 3:19): "That you may be filled unto all the fulness of God." Therefore the fulness of grace is not proper to Christ.

Objection 3: Further, the state of the wayfarer seems to be proportioned to the state of the comprehensor. But in the state of the comprehensor there will be a certain fulness, since "in our heavenly country with its fulness of all good, although some things are bestowed in a pre-eminent way, yet nothing is possessed singularly," as is clear from Gregory (Hom. De Cent. Ovib.; xxxiv in Ev.). Therefore in the state of the comprehensor the fulness of grace is possessed by everyone, and hence the fulness of grace is not proper to Christ. on the contrary, The fulness of grace is attributed to Christ inasmuch as He is the only-begotten of the Father, according to Jn. 1:14: "We saw Him [Vulg.: 'His glory'] as it were... the Only-begotten of the Father, full of grace and truth." But to be the Only-begotten of the Father is proper to Christ. Therefore it is proper to Him to be full of grace and truth.

I answer that, The fulness of grace may be taken in two ways: First, on the part of grace itself, or secondly on the part of the one who has grace. Now on the part of grace itself there is said to be the fulness of grace when the limit of grace is attained, as to essence and power, inasmuch as grace is possessed in its highest possible excellence and in its greatest possible extension to all its effects. And this fulness of grace is proper to Christ. But on the part of the subject there is said to be the fulness of grace when anyone fully possesses grace according to his condition—whether as regards intensity, by reason of grace being intense in him, to the limit assigned by God, according to Eph. 4:1: "But to every one of us is given grace according to the measure of the giving of Christ"—or "as regards power," by reason of a man having the help of grace for all that belongs to his office or state, as the Apostle says (Eph. 3:8): "To me, the least of all the saints, is given this grace... to enlighten all men." And this fulness of grace is not proper to Christ, but is communicated to others by Christ.

Reply to Objection 1: The Blessed Virgin is said to be full of grace, not on the part of grace itself—since she had not grace in its greatest possible excellence—nor for all the effects of grace; but she is said to be full of grace in reference to herself, i.e. inasmuch as she had sufficient grace for the state to which God had chosen her, i.e. to be the mother of His Only-begotten. So, too, Stephen is said to be full of grace, since he had sufficient grace to be a fit minister and witness of God, to which office he had been called. And the same must be said of others. Of these fulnesses one is greater than another, according as one is divinely pre-ordained to a higher or lower state.

Reply to Objection 2: The Apostle is there speaking of that fulness which has reference to the subject, in comparison with what man is divinely pre-ordained to; and this is either something in common, to which all the saints are pre-ordained, or something special, which pertains to the pre-eminence of some. And in this manner a certain fulness of grace is common to all the saints, viz. to have grace enough to merit eternal life, which consists in the enjoyment of God. And this is the fulness of grace which the Apostle desires for the faithful to whom he writes.

Reply to Objection 3: These gifts which are in common in heaven, viz.: vision, possession and fruition, and the like, have certain gifts corresponding to them in this life which are also common to all the saints. Yet there are certain prerogatives of saints, both in heaven and on earth, which are not possessed by all.

Objection 1: It would seem that Christ's grace is infinite. For everything immeasurable is infinite. But the grace of Christ is immeasurable; since it is written (Jn. 3:34): "For God doth not give the Spirit by measure to His Son [*'To His Son' is lacking in the Vulgate], namely Christ." Therefore the grace of Christ is infinite.

Objection 2: Further, an infinite effect betokens an infinite power which can only spring from an infinite essence. But the effect of Christ's grace is infinite, since it extends to the salvation of the whole human race; for He is the propitiation for our sins... and for those of the whole world, as is said (1 Jn. 2:2). Therefore the grace of Christ is infinite.

Objection 3: Further, every finite thing by addition can attain to the quantity of any other finite thing. Therefore if the grace of Christ is finite the grace of any other man could increase to such an extent as to reach to an equality with Christ's grace, against what is written (Job 28:17): "Gold nor crystal cannot equal it," as Gregory expounds it (Moral. xviii). Therefore the grace of Christ is infinite.

On the contrary, Grace is something created in the soul. But every created thing is finite, according to Wis. 11:21: "Thou hast ordered all things in measure and number and weight." Therefore the grace of Christ is not infinite.

I answer that, As was made clear above (Q[2], A[10]), a twofold grace may be considered in Christ; the first being the grace of union, which, as was said (Q[6], A[6]), is for Him to be personally united to the Son of God, which union has been bestowed gratis on the human nature; and it is clear that this grace is infinite, as the Person of God is infinite. The second is habitual grace; which may be taken in two ways: first as a being, and in this way it must be a finite being, since it is in the soul of Christ, as in a subject, and Christ's soul is a creature having a finite capacity; hence the being of grace cannot be infinite, since it cannot exceed its subject. Secondly it may be viewed in its specific nature of grace; and thus the grace of Christ can be termed infinite, since it is not limited, i.e. it has whatsoever can pertain to the nature of grace, and what pertains to the nature of grace is not bestowed on Him in a fixed measure; seeing that "according to the purpose" of God to Whom it pertains to measure grace, it is bestowed on Christ's soul as on a universal principle for bestowing grace on human nature, according to Eph. 1:5,6, "He hath graced us in His beloved Son"; thus we might say that the light of the sun is infinite, not indeed in being, but in the nature of light, as having whatever can pertain to the nature of light.

Reply to Objection 1: When it is said that the Father "doth not give the Spirit by measure," it may be expounded of the gift which God the Father from all eternity gave the Son, viz. the Divine Nature, which is an infinite gift. Hence the comment of a certain gloss: "So that the Son may be as great as the Father is." Or again, it may be referred to the gift which is given the human nature, to be united to the Divine Person, and this also is an infinite gift. Hence a gloss says on this text: "As the Father begot a full and perfect Word, it is united thus full and perfect to human nature." Thirdly, it may be referred to habitual grace, inasmuch as the grace of Christ extends to whatever belongs to grace. Hence Augustine expounding this (Tract. xiv in Joan.) says: "The division of the gifts is a measurement. For to one indeed by the Spirit is given the word of wisdom, to another the word of knowledge." But Christ the giver does not receive by measure.

Reply to Objection 2: The grace of Christ has an infinite effect, both because of the aforesaid infinity of grace, and because of the unity [*Perhaps we should read 'infinity'—Ed.] of the Divine Person, to Whom Christ's soul is united.

Reply to Objection 3: The lesser can attain by augment to the quantity of the greater, when both have the same kind of quantity. But the grace of any man is compared to the grace of Christ as a particular to a universal power; hence as the force of fire, no matter how much it increases, can never equal the sun's strength, so the grace of a man, no matter how much it increases, can never equal the grace of Christ.

Objection 1: It would seem that the grace of Christ could increase. For to every finite thing addition can be made. But the grace of Christ was finite. Therefore it could increase.

Objection 2: Further, it is by Divine power that grace is increased, according to 2 Cor. 9:8: "And God is able to make all grace abound in you." But the Divine power, being infinite, is confined by no limits. Therefore it seems that the grace of Christ could have been greater.

Objection 3: Further, it is written (Lk. 2:52) that the child "Jesus advanced in wisdom and age and grace with God and men." Therefore the grace of Christ could increase.

On the contrary, It is written (Jn. 1:14): "We saw Him [Vulg.: 'His glory'] as it were... the Only-begotten of the Father, full of grace and truth." But nothing can be or can be thought greater than that anyone should be the Only-begotten of the Father. Therefore no greater grace can be or can be thought than that of which Christ was full.

I answer that, For a form to be incapable of increase happens in two ways: First on the part of the subject; secondly, on the part of the form itself. On the part of the subject, indeed, when the subject reaches the utmost limit wherein it partakes of this form, after its own manner, e.g. if we say that air cannot increase in heat, when it has reached the utmost limit of heat which can exist in the nature of air, although there may be greater heat in actual existence, viz. the heat of fire. But on the part of the form, the possibility of increase is excluded when a subject reaches the utmost perfection which this form can have by nature, e.g. if we say the heat of fire cannot be increased because there cannot be a more perfect grade of heat than that to which fire attains. Now the proper measure of grace, like that of other forms, is determined by the Divine wisdom, according to Wis. 11:21: "Thou hast ordered all things in number, weight and measure." And it is with reference to its end that a measure is set to every form. as there is no greater gravity than that of the earth, because there is no lower place than that of the earth. Now the end of grace is the union of the rational creature with God. But there can neither be nor be thought a greater union of the rational creature with God than that which is in the Person. And hence the grace of Christ reached the highest measure of grace. Hence it is clear that the grace of Christ cannot be increased on the part of grace. But neither can it be increased on the part of the subject, since Christ as man was a true and full comprehensor from the first instant of His conception. Hence there could have been no increase of grace in Him, as there could be none in the rest of the blessed, whose grace could not increase, seeing that they have reached their last end. But as regards men who are wholly wayfarers, their grace can be increased not merely on the part of the form, since they have not attained the highest degree of grace, but also on the part of the subject, since they have not yet attained their end.

Reply to Objection 1: If we speak of mathematical quantity, addition can be made to any finite quantity, since there is nothing on the part of finite quantity which is repugnant to addition. But if we speak of natural quantity, there may be repugnance on the part of the form to which a determined quantity is due, even as other accidents are determined. Hence the Philosopher says (De Anima ii, 41) that "there is naturally a term of all things, and a fixed limit of magnitude and increase." And hence to the quantity of the whole there can be no addition. And still more must we suppose a term in the forms themselves, beyond which they may not go. Hence it is not necessary that addition should be capable of being made to Christ's grace, although it is finite in its essence.

Reply to Objection 2: Although the Divine power can make something greater and better than the habitual grace of Christ, yet it could not make it to be ordained to anything greater than the personal union with the Only-begotten Son of the Father; and to this union, by the purpose of the Divine wisdom, the measure of grace is sufficient.

Reply to Objection 3: Anyone may increase in wisdom and grace in two ways. First inasmuch as the very habits of wisdom and grace are increased; and in this way Christ did not increase. Secondly, as regards the effects, i.e. inasmuch as they do wiser and greater works; and in this way Christ increased in wisdom and grace even as in age, since in the course of time He did more perfect works, to prove Himself true man, both in the things of God, and in the things of man.

Objection 1: It would seem that the habitual grace did not follow after the union. For nothing follows itself. But this habitual grace seems to be the same as the grace of union; for Augustine says (De Praedest. Sanct. xv): "Every man becomes a Christian from the beginning of his belief, by the same grace whereby this Man from His beginning became Christ"; and of these two the first pertains to habitual grace and the second to the grace of union. Therefore it would seem that habitual grace did not follow upon the union.

Objection 2: Further, disposition precedes perfection, if not in time, at least in thought. But the habitual grace seems to be a disposition in human nature for the personal union. Therefore it seems that the habitual grace did not follow but rather preceded the union.

Objection 3: Further, the common precedes the proper. But habitual grace is common to Christ and other men; and the grace of union is proper to Christ. Therefore habitual grace is prior in thought to the union. Therefore it does not follow it.

On the contrary, It is written (Is. 42:1): "Behold my servant, I will uphold Him... "and farther on: "I have given My Spirit upon Him"; and this pertains to the gift of habitual grace. Hence it remains that the assumption of human nature to the unity of the Person preceded the habitual grace of Christ.

I answer that, The union of the human nature with the Divine Person, which, as we have said above (Q[2], A[10]; Q[6], A[6]), is the grace of union, precedes the habitual grace of Christ, not in order of time, but by nature and in thought; and this for a triple reason: First, with reference to the order of the principles of both. For the principle of the union is the Person of the Son assuming human nature, Who is said to be sent into the world, inasmuch as He assumed human nature; but the principle of habitual grace, which is given with charity, is the Holy Ghost, Who is said to be sent inasmuch as He dwells in the mind by charity. Now the mission of the Son is prior, in the order of nature, to the mission of the Holy Ghost, even as in the order of nature the Holy Ghost proceeds from the Son, and love from wisdom. Hence the personal union, according to which the mission of the Son took place, is prior in the order of nature to habitual grace, according to which the mission of the Holy Ghost takes place. Secondly, the reason of this order may be taken from the relation of grace to its cause. For grace is caused in man by the presence of the Godhead, as light in the air by the presence of the sun. Hence it is written (Ezech. 43:2): "The glory of the God of Israel came in by the way of the east... and the earth shone with His majesty." But the presence of God in Christ is by the union of human nature with the Divine Person. Hence the habitual grace of Christ is understood to follow this union, as light follows the sun. Thirdly, the reason of this union can be taken from the end of grace, since it is ordained to acting rightly, and action belongs to the suppositum and the individual. Hence action and, in consequence, grace ordaining thereto, presuppose the hypostasis which operates. Now the hypostasis did not exist in the human nature before the union, as is clear from Q[4], A[2]. Therefore the grace of union precedes, in thought, habitual grace.

Reply to Objection 1: Augustine here means by grace the gratuitous will of God, bestowing benefits gratis; and hence every man is said to be made a Christian by the same grace whereby a Man became Christ, since both take place by the gratuitous will of God without merits.

Reply to Objection 2: As disposition in the order of generation precedes the perfection to which it disposes, in such things as are gradually perfected; so it naturally follows the perfection which one has already obtained; as heat, which was a disposition to the form of fire, is an effect flowing from the form of already existing fire. Now the human nature in Christ is united to the Person of the Word from the beginning without succession. Hence habitual grace is not understood to have preceded the union, but to have followed it; as a natural property. Hence, as Augustine says (Enchiridion xl): "Grace is in a manner natural to the Man Christ."

Reply to Objection 3: The common precedes the proper, when both are of the same genus; but when they are of divers genera, there is nothing to prevent the proper being prior to the common. Now the grace of union is not in the same genus as habitual grace; but is above all genera even as the Divine Person Himself. Hence there is nothing to prevent this proper from being before the common since it does not result from something being added to the common, but is rather the principle and source of that which is common.

OF THE GRACE OF CHRIST, AS HE IS THE HEAD OF THE CHURCH (EIGHT ARTICLES)

We must now consider the grace of Christ as the Head of the Church; and under this head there are eight points of inquiry:

(1) Whether Christ is the Head of the Church?

(2) Whether He is the Head of men as regards their bodies or only as regards their souls?

(3) Whether He is the Head of all men?

(4) Whether He is the Head of the angels?

(5) Whether the grace of Christ as Head of the Church is the same as His habitual grace as an individual man?

(6) Whether to be Head of the Church is proper to Christ?

(7) Whether the devil is the head of all the wicked?

(8) Whether Anti-christ can be called the head of all the wicked?

Objection 1: It would seem that it does not belong to Christ as man to be Head of the Church. For the head imparts sense and motion to the members. Now spiritual sense and motion which are by grace, are not imparted to us by the Man Christ, because, as Augustine says (De Trin. i, 12; xv, 24), "not even Christ, as man, but only as God, bestows the Holy Ghost." Therefore it does not belong to Him as man to be Head of the Church.

Objection 2: Further, it is not fitting for the head to have a head. But God is the Head of Christ, as man, according to 1 Cor. 11:3, "The Head of Christ is God." Therefore Christ Himself is not a head.

Objection 3: Furthermore, the head of a man is a particular member, receiving an influx from the heart. But Christ is the universal principle of the whole Church. Therefore He is not the Head of the Church.

On the contrary, It is written (Eph. 1:22): "And He... hath made Him head over all the Church."

I answer that, As the whole Church is termed one mystic body from its likeness to the natural body of a man, which in divers members has divers acts, as the Apostle teaches (Rom. 12; 1 Cor. 12), so likewise Christ is called the Head of the Church from a likeness with the human head, in which we may consider three things, viz. order, perfection, and power: "Order," indeed; for the head is the first part of man, beginning from the higher part; and hence it is that every principle is usually called a head according to Ezech. 16:25: "At every head of the way, thou hast set up a sign of thy prostitution"—"Perfection," inasmuch as in the head dwell all the senses, both interior and exterior, whereas in the other members there is only touch, and hence it is said (Is. 9:15): "The aged and honorable, he is the head"—"Power," because the power and movement of the other members, together with the direction of them in their acts, is from the head, by reason of the sensitive and motive power there ruling; hence the ruler is called the head of a people, according to 1 Kings 15:17: "When thou wast a little one in thy own eyes, wast thou not made the head of the tribes of Israel?" Now these three things belong spiritually to Christ. First, on account of His nearness to God His grace is the highest and first, though not in time, since all have received grace on account of His grace, according to Rom. 8:29: "For whom He foreknew, He also predestinated to be made conformable to the image of His Son; that He might be the first-born amongst many brethren." Secondly, He had perfection as regards the fulness of all graces, according to Jn. 1:14, "We saw Him [Vulg.: 'His glory']... full of grace and truth," as was shown, Q[7], A[9]. Thirdly, He has the power of bestowing grace on all the members of the Church, according to Jn. 1:16: "Of His fulness we have all received." And thus it is plain that Christ is fittingly called the Head of the Church.

Reply to Objection 1: To give grace or the Holy Ghost belongs to Christ as He is God, authoritatively; but instrumentally it belongs also to Him as man, inasmuch as His manhood is the instrument of His Godhead. And hence by the power of the Godhead His actions were beneficial, i.e. by causing grace in us, both meritoriously and efficiently. But Augustine denies that Christ as man gives the Holy Ghost authoritatively. Even other saints are said to give the Holy Ghost instrumentally, or ministerially, according to Gal. 3:5: "He... who giveth to you the Spirit."

Reply to Objection 2: In metaphorical speech we must not expect a likeness in all respects; for thus there would be not likeness but identity. Accordingly a natural head has not another head because one human body is not part of another; but a metaphorical body, i.e. an ordered multitude, is part of another multitude as the domestic multitude is part of the civil multitude; and hence the father who is head of the domestic multitude has a head above him, i.e. the civil governor. And hence there is no reason why God should not be the Head of Christ, although Christ Himself is Head of the Church.

Reply to Objection 3: The head has a manifest pre-eminence over the other exterior members; but the heart has a certain hidden influence. And hence the Holy Ghost is likened to the heart, since He invisibly quickens and unifies the Church; but Christ is likened to the Head in His visible nature in which man is set over man.

Objection 1: It would seem that Christ is not the Head of men as to their bodies. For Christ is said to be the Head of the Church inasmuch as He bestows spiritual sense and the movement of grace on the Church. But a body is not capable of this spiritual sense and movement. Therefore Christ is not the Head of men as regards their bodies.

Objection 2: Further, we share bodies with the brutes. If therefore Christ was the Head of men as to their bodies, it would follow that He was the Head of brute animals; and this is not fitting.

Objection 3: Further, Christ took His body from other men, as is clear from Mat. 1 and Luke 3. But the head is the first of the members, as was said above (A[1], ad 3). Therefore Christ is not the Head of the Church as regards bodies.

On the contrary, It is written (Phil. 3:21): "Who will reform the body of our lowness, made like to the body of His glory."

I answer that, The human body has a natural relation to the rational soul, which is its proper form and motor. Inasmuch as the soul is its form, it receives from the soul life and the other properties which belong specifically to man; but inasmuch as the soul is its motor, the body serves the soul instrumentally. Therefore we must hold that the manhood of Christ had the power of "influence," inasmuch as it is united to the Word of God, to Whom His body is united through the soul, as stated above (Q[6], A[1]). Hence the whole manhood of Christ, i.e. according to soul and body, influences all, both in soul and body; but principally the soul, and secondarily the body: First, inasmuch as the "members of the body are presented as instruments of justice" in the soul that lives through Christ, as the Apostle says (Rom. 6:13): secondly, inasmuch as the life of glory flows from the soul on to the body, according to Rom. 8:11: "He that raised up Jesus from the dead shall quicken also your mortal bodies, because of His Spirit that dwelleth in you."

Reply to Objection 1: The spiritual sense of grace does not reach to the body first and principally, but secondarily and instrumentally, as was said above.

Reply to Objection 2: The body of an animal has no relation to a rational soul, as the human body has. Hence there is no parity.

Reply to Objection 3: Although Christ drew the matter of His body from other men, yet all draw from Him the immortal life of their body, according to 1 Cor. 15:22: "And as in Adam all die, so also in Christ all shall be made alive."

Objection 1: It would seem that Christ is not the Head of all men. For the head has no relation except to the members of its body. Now the unbaptized are nowise members of the Church which is the body of Christ, as it is written (Eph. 1:23). Therefore Christ is not the Head of all men.

Objection 2: Further, the Apostle writes to the Ephesians (5:25,27): "Christ delivered Himself up for" the Church "that He might present it to Himself a glorious Church, not having spot or wrinkle or any such thing." But there are many of the faithful in whom is found the spot or the wrinkle of sin. Therefore Christ is not the Head of all the faithful.

Objection 3: Further, the sacraments of the Old Law are compared to Christ as the shadow to the body, as is written (Col. 2:17). But the fathers of the Old Testament in their day served unto these sacraments, according to Heb. 8:5: "Who serve unto the example and shadow of heavenly things." Hence they did not pertain to Christ's body, and therefore Christ is not the Head of all men.

On the contrary, It is written (1 Tim. 4:10): "Who is the Saviour of all men, especially of the faithful," and (1 Jn. 2:2): "He is the propitiation for our sins, and not for ours only, but also for those of the whole world." Now to save men and to be a propitiation for their sins belongs to Christ as Head. Therefore Christ is the Head of all men.

I answer that, This is the difference between the natural body of man and the Church's mystical body, that the members of the natural body are all together, and the members of the mystical are not all together—neither as regards their natural being, since the body of the Church is made up of the men who have been from the beginning of the world until its end—nor as regards their supernatural being, since, of those who are at any one time, some there are who are without grace, yet will afterwards obtain it, and some have it already. We must therefore consider the members of the mystical body not only as they are in act, but as they are in potentiality. Nevertheless, some are in potentiality who will never be reduced to act, and some are reduced at some time to act; and this according to the triple class, of which the first is by faith, the second by the charity of this life, the third by the fruition of the life to come. Hence we must say that if we take the whole time of the world in general, Christ is the Head of all men, but diversely. For, first and principally, He is the Head of such as are united to Him by glory; secondly, of those who are actually united to Him by charity; thirdly, of those who are actually united to Him by faith; fourthly, of those who are united to Him merely in potentiality, which is not yet reduced to act, yet will be reduced to act according to Divine predestination; fifthly, of those who are united to Him in potentiality, which will never be reduced to act; such are those men existing in the world, who are not predestined, who, however, on their departure from this world, wholly cease to be members of Christ, as being no longer in potentiality to be united to Christ.

Reply to Objection 1: Those who are unbaptized, though not actually in the Church, are in the Church potentially. And this potentiality is rooted in two things—first and principally, in the power of Christ, which is sufficient for the salvation of the whole human race; secondly, in free-will.

Reply to Objection 2: To be "a glorious Church not having spot or wrinkle" is the ultimate end to which we are brought by the Passion of Christ. Hence this will be in heaven, and not on earth, in which "if we say we have no sin, we deceive ourselves," as is written (1 Jn. 1:8). Nevertheless, there are some, viz. mortal, sins from which they are free who are members of Christ by the actual union of charity; but such as are tainted with these sins are not members of Christ actually, but potentially; except, perhaps, imperfectly, by formless faith, which unites to God, relatively but not simply, viz. so that man partake of the life of grace. For, as is written (James 2:20): "Faith without works is dead." Yet such as these receive from Christ a certain vital act, i.e. to believe, as if a lifeless limb were moved by a man to some extent.

Reply to Objection 3: The holy Fathers made use of the legal sacraments, not as realities, but as images and shadows of what was to come. Now it is the same motion to an image as image, and to the reality, as is clear from the Philosopher (De Memor. et Remin. ii). Hence the ancient Fathers, by observing the legal sacraments, were borne to Christ by the same faith and love whereby we also are borne to Him, and hence the ancient Fathers belong to the same Church as we.
