Summa Theologica Part IV (Tertia Pars) Part 16

Whether Christ Is the Head of the Church?

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 G.o.d, bestows the Holy Ghost." Therefore it does not belong to Him as man to be Head of the Church.

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

Obj. 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 prost.i.tution"--"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 (Isa. 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 G.o.d 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 John 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 John 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 Obj. 1: To give grace or the Holy Ghost belongs to Christ as He is G.o.d, authoritatively; but instrumentally it belongs also to Him as man, inasmuch as His manhood is the instrument of His G.o.dhead. And hence by the power of the G.o.dhead 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 Obj. 2: In metaphorical speech we must not expect a likeness in all respects; for thus there would be not likeness but ident.i.ty.

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 mult.i.tude, is part of another mult.i.tude as the domestic mult.i.tude is part of the civil mult.i.tude; and hence the father who is head of the domestic mult.i.tude has a head above him, i.e. the civil governor. And hence there is no reason why G.o.d should not be the Head of Christ, although Christ Himself is Head of the Church.

Reply Obj. 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.

SECOND ARTICLE [III, Q. 8, Art. 2]

Whether Christ Is the Head of Men As to Their Bodies or Only As to Their Souls?

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.

Obj. 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.

Obj. 3: Further, Christ took His body from other men, as is clear from Matt. 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 G.o.d, 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 princ.i.p.ally 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 Obj. 1: The spiritual sense of grace does not reach to the body first and princ.i.p.ally, but secondarily and instrumentally, as was said above.

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

Reply Obj. 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."

THIRD ARTICLE [III, Q. 8, Art. 3]

Whether Christ Is the Head of All Men?

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.

Obj. 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.

Obj. 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 John 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 cla.s.s, 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 princ.i.p.ally, 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 Obj. 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 princ.i.p.ally, in the power of Christ, which is sufficient for the salvation of the whole human race; secondly, in free-will.

Reply Obj. 2: To be "a glorious Church not having spot or wrinkle" is the ultimate end to which we are brought by the Pa.s.sion 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 John 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 G.o.d, 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 Obj. 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.

FOURTH ARTICLE [III, Q. 8, Art. 4]

Whether Christ Is the Head of the Angels?

Objection 1: It would seem that Christ as man is not the head of the angels. For the head and members are of one nature. But Christ as man is not of the same nature with the angels, but only with men, since, as is written (Heb. 2:16): "For nowhere doth He take hold of the angels, but of the seed of Abraham He taketh hold." Therefore Christ as man is not the head of the angels.

Obj. 2: Further, Christ is the head of such as belong to the Church, which is His Body, as is written (Eph. 1:23). But the angels do not belong to the Church. For the Church is the congregation of the faithful: and in the angels there is no faith, for they do not "walk by faith" but "by sight," otherwise they would be "absent from the Lord," as the Apostle argues (2 Cor. 5:6, 7). Therefore Christ as man is not head of the angels.

Obj. 3: Further, Augustine says (Tract. xix; xxiii in Joan.), that as "the Word" which "was in the beginning with the Father" quickens souls, so the "Word made flesh" quickens bodies, which angels lack.

But the Word made flesh is Christ as man. Therefore Christ as man does not give life to angels, and hence as man He is not the head of the angels.

_On the contrary,_ The Apostle says (Col. 2:10), "Who is the head of all Princ.i.p.ality and Power," and the same reason holds good with the other orders of angels. Therefore Christ is the Head of the angels.

_I answer that,_ As was said above (A. 1, ad 2), where there is one body we must allow that there is one head. Now a mult.i.tude ordained to one end, with distinct acts and duties, may be metaphorically called one body. But it is manifest that both men and angels are ordained to one end, which is the glory of the Divine fruition. Hence the mystical body of the Church consists not only of men but of angels. Now of all this mult.i.tude Christ is the Head, since He is nearer G.o.d, and shares His gifts more fully, not only than man, but even than angels; and of His influence not only men but even angels partake, since it is written (Eph. 1:20-22): that G.o.d the Father set "Him," namely Christ, "on His right hand in the heavenly places, above all Princ.i.p.ality and Power and Virtue and Dominion and every name that is named not only in this world, but also in that which is to come. And He hath subjected all things under His feet." Therefore Christ is not only the Head of men, but of angels. Hence we read (Matt. 4:11) that "angels came and ministered to Him."

Reply Obj. 1: Christ's influence over men is chiefly with regard to their souls; wherein men agree with angels in generic nature, though not in specific nature. By reason of this agreement Christ can be said to be the Head of the angels, although the agreement falls short as regards the body.

Reply Obj. 2: The Church, on earth, is the congregation of the faithful; but, in heaven, it is the congregation of comprehensors.

Now Christ was not merely a wayfarer, but a comprehensor. And therefore He is the Head not merely of the faithful, but of comprehensors, as having grace and glory most fully.

Reply Obj. 3: Augustine here uses the similitude of cause and effect, i.e. inasmuch as corporeal things act on bodies, and spiritual things on spiritual things. Nevertheless, the humanity of Christ, by virtue of the spiritual nature, i.e. the Divine, can cause something not only in the spirits of men, but also in the spirits of angels, on account of its most close conjunction with G.o.d, i.e. by personal union.

FIFTH ARTICLE [III, Q. 8, Art. 5]

Whether the Grace of Christ, As Head of the Church, Is the Same As His Habitual Grace, Inasmuch As He Is Man?

Objection 1: It would seem that the grace whereby Christ is Head of the Church and the individual grace of the Man are not the same. For the Apostle says (Rom. 5:15): "If by the offense of one many died, much more the grace of G.o.d and the gift, by the grace of one man, Jesus Christ, hath abounded unto many." But the actual sin of Adam is distinct from original sin which he transmitted to his posterity.

Hence the personal grace which is proper to Christ is distinct from His grace, inasmuch as He is the Head of the Church, which flows to others from Him.
