Part IV (Tertia Pars) Part 16 (1/2)
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.
