Summa Theologica, by St. Thomas Aquinas, [1947], at sacred-texts.com
We have now to consider Christ's Ascension: concerning which there are six points of inquiry:
(1) Whether it belonged for Christ to ascend into heaven?
(2) According to which nature did it become Him to ascend?
(3) Whether He ascended by His own power?
(4) Whether He ascended above all the corporeal heavens?
(5) Whether He ascended above all spiritual creatures?
(6) Of the effect of the Ascension.
Objection 1: It would seem that it was not fitting for Christ to ascend into heaven. For the Philosopher says (De Coelo ii) that "things which are in a state of perfection possess their good without movement." But Christ was in a state of perfection, since He is the Sovereign Good in respect of His Divine Nature, and sovereignly glorified in respect of His human nature. Consequently, He has His good without movement. But ascension is movement. Therefore it was not fitting for Christ to ascend.
Objection 2: Further, whatever is moved, is moved on account of something better. But it was no better thing for Christ to be in heaven than upon earth, because He gained nothing either in soul or in body by being in heaven. Therefore it seems that Christ should not have ascended into heaven.
Objection 3: Further, the Son of God took human flesh for our salvation. But it would have been more beneficial for men if He had tarried always with us upon earth; thus He said to His disciples (Lk. 17:22): "The days will come when you shall desire to see one day of the Son of man; and you shall not see it." Therefore it seems unfitting for Christ to have ascended into heaven.
Objection 4: Further, as Gregory says (Moral. xiv), Christ's body was in no way changed after the Resurrection. But He did not ascend into heaven immediately after rising again, for He said after the Resurrection (Jn. 20:17): "I am not yet ascended to My Father." Therefore it seems that neither should He have ascended after forty days.
On the contrary, Are the words of our Lord (Jn. 20:17): "I ascend to My Father and to your Father."
I answer that, The place ought to be in keeping with what is contained therein. Now by His Resurrection Christ entered upon an immortal and incorruptible life. But whereas our dwelling-place is one of generation and corruption, the heavenly place is one of incorruption. And consequently it was not fitting that Christ should remain upon earth after the Resurrection; but it was fitting that He should ascend to heaven.
Reply to Objection 1: That which is best and possesses its good without movement is God Himself, because He is utterly unchangeable, according to Malachi 3:6: "I am the Lord, and I change not." But every creature is changeable in some respect, as is evident from Augustine (Gen. ad lit. viii). And since the nature assumed by the Son of God remained a creature, as is clear from what was said above (Q[2], A[7]; Q[16], AA[8],10; Q[20], A[1] ), it is not unbecoming if some movement be attributed to it.
Reply to Objection 2: By ascending into heaven Christ acquired no addition to His essential glory either in body or in soul: nevertheless He did acquire something as to the fittingness of place, which pertains to the well-being of glory: not that His body acquired anything from a heavenly body by way of perfection or preservation; but merely out of a certain fittingness. Now this in a measure belonged to His glory; and He had a certain kind of joy from such fittingness, not indeed that He then began to derive joy from it when He ascended into heaven, but that He rejoiced thereat in a new way, as at a thing completed. Hence, on Ps. 15:11: "At Thy right hand are delights even unto the end," the gloss says: "I shall delight in sitting nigh to Thee, when I shall be taken away from the sight of men."
Reply to Objection 3: Although Christ's bodily presence was withdrawn from the faithful by the Ascension, still the presence of His Godhead is ever with the faithful, as He Himself says (Mat. 28:20): "Behold, I am with you all days, even to the consummation of the world." For, "by ascending into heaven He did not abandon those whom He adopted," as Pope Leo says (De Resurrec., Serm. ii). But Christ's Ascension into heaven, whereby He withdrew His bodily presence from us, was more profitable for us than His bodily presence would have been.
First of all, in order to increase our faith, which is of things unseen. Hence our Lord said (Jn. 26) that the Holy Ghost shall come and "convince the world . . . of justice," that is, of the justice "of those that believe," as Augustine says (Tract. xcv super Joan.): "For even to put the faithful beside the unbeliever is to put the unbeliever to shame"; wherefore he goes on to say (10): "'Because I go to the Father; and you shall see Me no longer'"---"For 'blessed are they that see not, yet believe.' Hence it is of our justice that the world is reproved: because 'you will believe in Me whom you shall not see.'"
Secondly, to uplift our hope: hence He says (Jn. 14:3): "If I shall go, and prepare a place for you, I will come again, and will take you to Myself; that where I am, you also may be." For by placing in heaven the human nature which He assumed, Christ gave us the hope of going thither; since "wheresoever the body shall be, there shall the eagles also be gathered together," as is written in Mat. 24:28. Hence it is written likewise (Mic. 2:13): "He shall go up that shall open the way before them."
Thirdly, in order to direct the fervor of our charity to heavenly things. Hence the Apostle says (Col. 3:1, 2): "Seek the things that are above, where Christ is sitting at the right hand of God. Mind the things that are above, not the things that are upon the earth": for as is said (Mat. 6:21): "Where thy treasure is, there is thy heart also." And since the Holy Ghost is love drawing us up to heavenly things, therefore our Lord said to His disciples (Jn. 16:7): "It is expedient to you that I go; for if I go not, the Paraclete will not come to you; but if I go, I will send Him to you." On which words Augustine says (Tract. xciv super Joan.): "Ye cannot receive the Spirit, so long as ye persist in knowing Christ according to the flesh. But when Christ withdrew in body, not only
the Holy Ghost, but both Father and Son were present with them spiritually."
Reply to Objection 4: Although a heavenly place befitted Christ when He rose to immortal life, nevertheless He delayed the Ascension in order to confirm the truth of His Resurrection. Hence it is written (Acts 1:3), that "He showed Himself alive after His Passion, by many proofs, for forty days appearing to them": upon which the gloss says that "because He was dead for forty hours, during forty days He established the fact of His being alive again. Or the forty days may be understood as a figure of this world, wherein Christ dwells in His Church: inasmuch as man is made out of the four elements, and is cautioned not to transgress the Decalogue."
Objection 1: It would seem that Christ's Ascension into heaven belonged to Him according to His Divine Nature. For, it is written (Ps. 46:6): "God is ascended with jubilee": and (Dt. 33:26): "He that is mounted upon the heaven is thy helper." But these words were spoken of God even before Christ's Incarnation. Therefore it belongs to Christ to ascend into heaven as God.
Objection 2: Further, it belongs to the same person to ascend into heaven as to descend from heaven, according to Jn. 3:13: "No man hath ascended into heaven, but He that descended from heaven": and Eph. 4:10: "He that descended is the same also that ascended." But Christ came down from heaven not as man, but as God: because previously His Nature in heaven was not human, but Divine. Therefore it seems that Christ ascended into heaven as God.
Objection 3: Further, by His Ascension Christ ascended to the Father. But it was not as man that He rose to equality with the Father; for in this respect He says: "He is greater than I," as is said in Jn. 14:28. Therefore it seems that Christ ascended as God.
On the contrary, on Eph. 4:10: "That He ascended, what is it, but because He also descended," a gloss says: "It is clear that He descended and ascended according to His humanity."
I answer that, The expression "according to" can denote two things; the condition of the one who ascends, and the cause of his ascension. When taken to express the condition of the one ascending, the Ascension in no wise belongs to Christ according to the condition of His Divine Nature; both because there is nothing higher than the Divine Nature to which He can ascend; and because ascension is local motion, a thing not in keeping with the Divine Nature, which is immovable and outside all place. Yet the Ascension is in keeping with Christ according to His human nature, which is limited by place, and can be the subject of motion. In this sense, then, we can say that Christ ascended into heaven as man, but not as God.
But if the phrase "according to" denote the cause of the Ascension, since Christ ascended into heaven in virtue of His Godhead, and not in virtue of His human nature, then it must be said that Christ ascended into heaven not as man, but as God. Hence Augustine says in a sermon on the Ascension: "It was our doing that the Son of man hung upon the cross; but it was His own doing that He ascended."
Reply to Objection 1: These utterances were spoken prophetically of God who was one day to become incarnate. Still it can be said that although to ascend does not belong to the Divine Nature properly, yet it can metaphorically; as, for instance, it is said "to ascend in the heart of man" (cf. Ps. 83:6), when his heart submits and humbles itself before God: and in the same way God is said to ascend metaphorically with regard to every creature, since He subjects it to Himself.
Reply to Objection 2: He who ascended is the same as He who descended. For Augustine says (De Symb. iv): "Who is it that descends? The God-Man. Who is it that ascends? The self-same God-Man." Nevertheless a twofold descent is attributed to Christ; one, whereby He is said to have descended from heaven, which is attributed to the God-Man according as He is God: for He is not to be understood as having descended by any local movement, but as having "emptied Himself," since "when He was in the form of God He took the form of a servant." For just as He is said to be emptied, not by losing His fulness, but because He took our littleness upon Himself, so likewise He is said to have descended from heaven, not that He deserted heaven, but because He assumed human nature in unity of person.
And there is another descent whereby He descended "into the lower regions of the earth," as is written Eph. 4:9; and this is local descent: hence this belongs to Christ according to the condition of human nature.
Reply to Objection 3: Christ is said to ascend to the Father, inasmuch as He ascends to sit on the right hand of the Father; and this is befitting Christ in a measure according to His Divine Nature, and in a measure according to His human nature, as will be said later (Q[58], A[3])
Objection 1: It would seem that Christ did not ascend by His own power, because it is written (Mk. 16:19) that "the Lord Jesus, after He had spoken to them, was taken up to heaven"; and (Acts 1:9) that, "while they looked on, He was raised up, and a cloud received Him out of their sight." But what is taken up, and lifted up, appears to be moved by another. Consequently, it was not by His own power, but by another's that Christ was taken up into heaven.
Objection 2: Further, Christ's was an earthly body, like to ours. But it is contrary to the nature of an earthly body to be borne upwards. Moreover, what is moved contrary to its nature is nowise moved by its own power. Therefore Christ did not ascend to heaven by His own power.
Objection 3: Further, Christ's own power is Divine. But this motion does not seem to have been Divine, because, whereas the Divine power is infinite, such motion would be instantaneous; consequently, He would not have been uplifted to heaven "while" the disciples "looked on," as is stated in Acts 1:9. Therefore, it seems that Christ did not ascend to heaven by His own power.
On the contrary, It is written (Is. 63:1): "This beautiful one in his robe, walking in the greatness of his strength." Also Gregory says in a Homily on the Ascension (xxix): "It is to be noted that we read of Elias having ascended in a chariot, that it might be shown that one who was mere man needed another's help. But we do not read of our Saviour being lifted up either in a chariot or by angels, because He who had made all things was taken up above all things by His own power."
I answer that, There is a twofold nature in Christ, to wit, the Divine and the human. Hence His own power can be accepted according to both. Likewise a twofold power can be accepted regarding His human nature: one is natural, flowing from the principles of nature; and it is quite evident that Christ did not ascend into heaven by such power as this. The other is the power of glory, which is in Christ's human nature; and it was according to this that He ascended to heaven.
Now there are some who endeavor to assign the cause of this power to the nature of the fifth essence. This, as they say, is light, which they make out to be of the composition of the human body, and by which they contend that contrary elements are reconciled; so that in the state of this mortality, elemental nature is predominant in human bodies: so that, according to the nature of this predominating element the human body is borne downwards by its own power: but in the condition of glory the heavenly nature will predominate, by whose tendency and power Christ's body and the bodies of the saints are lifted up to heaven. But we have already treated of this opinion in the FP, Q[76], A[7], and shall deal with it more fully in treating of the general resurrection (XP, Q[84], A[1]).
Setting this opinion aside, others assign as the cause of this power the glorified soul itself, from whose overflow the body will be glorified, as Augustine writes to Dioscorus (Ep. cxviii). For the glorified body will be so submissive to the glorified soul, that, as Augustine says (De Civ. Dei xxii), "wheresoever the spirit listeth, thither the body will be on the instant; nor will the spirit desire anything unbecoming to the soul or the body." Now it is befitting the glorified and immortal body for it to be in a heavenly place, as stated above (A[1]). Consequently, Christ's body ascended into heaven by the power of His soul willing it. But as the body is made glorious by participation with the soul, even so, as Augustine says (Tract. xxiii in Joan.), "the soul is beatified by participating in God." Consequently, the Divine power is the first source of the ascent into heaven. Therefore Christ ascended into heaven by His own power, first of all by His Divine power, and secondly by the power of His glorified soul moving His body at will.
Reply to Objection 1: As Christ is said to have risen by His own power, though He was raised to life by the power of the Father, since the Father's power is the same as the Son's; so also Christ ascended into heaven by His own power, and yet was raised up and taken up to heaven by the Father.
Reply to Objection 2: This argument proves that Christ did not ascend into heaven by His own power, i.e. that which is natural to human nature: yet He did ascend by His own power, i.e. His Divine power, as well as by His own power, i.e. the power of His beatified soul. And although to mount upwards is contrary to the nature of a human body in its present condition, in which the body is not entirely dominated by the soul, still it will not be unnatural or forced in a glorified body, whose entire nature is utterly under the control of the spirit.
Reply to Objection 3: Although the Divine power be infinite, and operate infinitely, so far as the worker is concerned, still the effect thereof is received in things according to their capacity, and as God disposes. Now a body is incapable of being moved locally in an instant, because it must be commensurate with space, according to the division of which time is reckoned, as is proved in Physics vi. Consequently, it is not necessary for a body moved by God to be moved instantaneously, but with such speed as God disposes.
Objection 1: It would seem that Christ did not ascend above all the heavens, for it is written (Ps. 10:5): "The Lord is in His holy temple, the Lord's throne is in heaven." But what is in heaven is not above heaven. Therefore Christ did not ascend above all the heavens.
Objection 2: [*This objection with its solution is omitted in the Leonine edition as not being in the original manuscript.]
Further, there is no place above the heavens, as is proved in De Coelo i. But every body must occupy a place. Therefore Christ's body did not ascend above all the heavens.
Objection 3: Further, two bodies cannot occupy the same place. Since, then, there is no passing from place to place except through the middle space, it seems that Christ could not have ascended above all the heavens unless heaven were divided; which is impossible.
Objection 4: Further, it is narrated (Acts 1:9) that "a cloud received Him out of their sight." But clouds cannot be uplifted beyond heaven. Consequently, Christ did not ascend above all the heavens.
Objection 5: Further, we believe that Christ will dwell for ever in the place whither He has ascended. But what is against nature cannot last for ever, because what is according to nature is more prevalent and of more frequent occurrence. Therefore, since it is contrary to nature for an earthly body to be above heaven, it seems that Christ's body did not ascend above heaven.
On the contrary, It is written (Eph. 4:10): "He ascended above all the heavens that He might fill all things."
I answer that, The more fully anything corporeal shares in the Divine goodness, the higher its place in the corporeal order, which is order of place. Hence we see that the more formal bodies are naturally the higher, as is clear from the Philosopher (Phys. iv; De Coelo ii), since it is by its form that every body partakes of the Divine Essence, as is shown in Physics i. But through glory the body derives a greater share in the Divine goodness than any other natural body does through its natural form; while among other glorious bodies it is manifest that Christ's body shines with greater glory. Hence it was most fitting for it to be set above all bodies. Thus it is that on Eph. 4:8: "Ascending on high," the gloss says: "in place and dignity."
Reply to Objection 1: God's seat is said to be in heaven, not as though heaven contained Him, but rather because it is contained by Him. Hence it is not necessary for any part of heaven to be higher, but for Him to be above all the heavens; according to Ps. 8:2: "For Thy magnificence is elevated above the heavens, O God!"
Reply to Objection 2: [*Omitted in Leonine edition; see OBJ[2]]
A place implies the notion of containing; hence the first container has the formality of first place, and such is the first heaven. Therefore bodies need in themselves to be in a place, in so far as they are contained by a heavenly body. But glorified bodies, Christ's especially, do not stand in need of being so contained, because they draw nothing from the heavenly bodies, but from God through the soul. So there is nothing to prevent Christ's body from being beyond the containing radius of the heavenly bodies, and not in a containing place. Nor is there need for a vacuum to exist outside heaven, since there is no place there, nor is there any potentiality susceptive of a body, but the potentiality of reaching thither lies in Christ. So when Aristotle proves (De Coelo ii) that there is no body beyond heaven, this must be understood of bodies which are in a state of pure nature, as is seen from the proofs.
Reply to Objection 3: Although it is not of the nature of a body for it to be in the same place with another body, yet God can bring it about miraculously that a body be with another in the same place, as Christ did when He went forth from the Virgin's sealed womb, also when He entered among the disciples through closed doors, as Gregory says (Hom. xxvi). Therefore Christ's body can be in the same place with another body, not through some inherent property in the body, but through the assistance and operation of the Divine power.
Reply to Objection 4: That cloud afforded no support as a vehicle to the ascending Christ: but it appeared as a sign of the Godhead, just as God's glory appeared to Israel in a cloud over the Tabernacle (Ex. 40:32; Num. 9:15).
Reply to Objection 5: A glorified body has the power to be in heaven or above heaven. not from its natural principles, but from the beatified soul, from which it derives its glory: and just as the upward motion of a glorified body is not violent, so neither is its rest violent: consequently, there is nothing to prevent it from being everlasting.
Objection 1: It would seem that Christ's body did not ascend above every spiritual creature. For no fitting comparison can be made between things which have no common ratio. But place is not predicated in the same ratio of bodies and of spiritual creatures, as is evident from what was said in the FP, Q[8], A[2], ad 1,2; FP, Q[52], A[1]. Therefore it seems that Christ's body cannot be said to have ascended above every spiritual creature.
Objection 2: Further, Augustine says (De Vera Relig. lv) that a spirit always takes precedence over a body. But the higher place is due to the higher things. Therefore it does not seem that Christ ascended above every spiritual creature.
Objection 3: Further, in every place a body exists, since there is no such thing as a vacuum in nature. Therefore if no body obtains a higher place than a spirit in the order of natural bodies, then there will be no place above every spiritual creature. Consequently, Christ's body could not ascend above every spiritual creature.
On the contrary, It is written (Eph. 1:21): "God set Him above all principality, and Power, and every name that is named, not only in this world, but also in that which is to come."
I answer that, The more exalted place is due to the nobler subject, whether it be a place according to bodily contact, as regards bodies, or whether it be by way of spiritual contact, as regards spiritual substances; thus a heavenly place which is the highest of places is becomingly due to spiritual substances, since they are highest in the order of substances. But although Christ's body is beneath spiritual substances, if we weigh the conditions of its corporeal nature, nevertheless it surpasses all spiritual substances in dignity, when we call to mind its dignity of union whereby it is united personally with God. Consequently, owing to this very fittingness, a higher place is due to it above every spiritual creature. Hence Gregory says in a Homily on the Ascension (xxix in Evang.) that "He who had made all things, was by His own power raised up above all things."
Reply to Objection 1: Although a place is differently attributed to corporeal and spiritual substances, still in either case this remains in common, that the higher place is assigned to the worthier.
Reply to Objection 2: This argument holds good of Christ's body according to the conditions of its corporeal nature, but not according to its formality of union.
Reply to Objection 3: This comparison may be considered either on the part of the places; and thus there is no place so high as to exceed the dignity of a spiritual substance: in this sense the objection runs. Or it may be considered on the part of the dignity of the things to which a place is attributed: and in this way it is due to the body of Christ to be above spiritual creatures.
Objection 1: It would seem that Christ's Ascension is not the cause of our salvation. For, Christ was the cause of our salvation in so far as He merited it. But He merited nothing for us by His Ascension, because His Ascension belongs to the reward of His exaltation: and the same thing is not both merit and reward, just as neither are a road and its terminus the same. Therefore it seems that Christ's Ascension is not the cause of our salvation.
Objection 2: Further, if Christ's Ascension be the cause of our salvation, it seems that this is principally due to the fact that His Ascension is the cause of ours. But this was bestowed upon us by His Passion, for it is written (Heb. 10:19): "We have [Vulg.: 'Having'] confidence in the entering into the holies by" His "blood." Therefore it seems that Christ's Ascension was not the cause of our salvation.
Objection 3: Further, the salvation which Christ bestows is an everlasting one, according to Is. 51:6: "My salvation shall be for ever." But Christ did not ascend into heaven to remain there eternally; for it is written (Acts 1:11): "He shall so come as you have seen Him going, into heaven." Besides, we read of Him showing Himself to many holy people on earth after He went up to heaven. to Paul, for instance (Acts 9). Consequently, it seems that Christ's Ascension is not the cause of our salvation.
On the contrary, He Himself said (Jn. 16:7): "It is expedient to you that I go"; i.e. that I should leave you and ascend into heaven.
I answer that, Christ's Ascension is the cause of our salvation in two ways: first of all, on our part; secondly, on His.
On our part, in so far as by the Ascension our souls are uplifted to Him; because, as stated above (A[1], ad 3), His Ascension fosters, first, faith; secondly, hope; thirdly, charity. Fourthly, our reverence for Him is thereby increased, since we no longer deem Him an earthly man, but the God of heaven; thus the Apostle says (2 Cor. 5:16): "If we have known Christ according to the flesh---'that is, as mortal, whereby we reputed Him as a mere man,'" as the gloss interprets the words---"but now we know Him so no longer."
On His part, in regard to those things which, in ascending, He did for our salvation. First, He prepared the way for our ascent into heaven, according to His own saying (Jn. 14:2): "I go to prepare a place for you," and the words of Micheas (2:13), "He shall go up that shall open the way before them." For since He is our Head the members must follow whither the Head has gone: hence He said (Jn. 14:3): "That where I am, you also may be." In sign whereof He took to heaven the souls of the saints delivered from hell, according to Ps. 67:19 (Cf. Eph. 4:8): "Ascending on high, He led captivity captive," because He took with Him to heaven those who had been held captives by the devil---to heaven, as to a place strange to human nature. captives in deed of a happy taking, since they were acquired by His victory.
Secondly, because as the high-priest under the Old Testament entered the holy place to stand before God for the people, so also Christ entered heaven "to make intercession for us," as is said in Heb. 7:25. Because the very showing of Himself in the human nature which He took with Him to heaven is a pleading for us. so that for the very reason that God so exalted human nature in Christ, He may take pity on them for whom the Son of God took human nature. Thirdly, that being established in His heavenly seat as God and Lord, He might send down gifts upon men, according to Eph. 4:10: "He ascended above all the heavens, that He might fill all things," that is, "with His gifts," according to the gloss.
Reply to Objection 1: Christ's Ascension is the cause of our salvation by way not of merit, but of efficiency, as was stated above regarding His Resurrection (Q[56], A[1], ad 3,4).
Reply to Objection 2: Christ's Passion is the cause of our ascending to heaven, properly speaking, by removing the hindrance which is sin, and also by way of merit: whereas Christ's Ascension is the direct cause of our ascension, as by beginning it in Him who is our Head, with whom the members must be united.
Reply to Objection 3: Christ by once ascending into heaven acquired for Himself and for us in perpetuity the right and worthiness of a heavenly dwelling-place; which worthiness suffers in no way, if, from some special dispensation, He sometimes comes down in body to earth; either in order to show Himself to the whole world, as at the judgment; or else to show Himself particularly to some individual, e.g. in Paul's case, as we read in Acts 9. And lest any man may think that Christ was not bodily present when this occurred, the contrary is shown from what the Apostle says in 1 Cor. 14:8, to confirm faith in the Resurrection: "Last of all He was seen also by me, as by one born out of due time": which vision would not confirm the truth of the Resurrection except he had beheld Christ's very body.
