CHRIST THE SAVIOUR
— A Commentary on the Third Part of St Thomas' Theological Summa

by Reginald Garrigou-Lagrange, O. P.


CHAPTER XV: QUESTION 13: THE POWER OF CHRIST'S SOUL

If Christ had, as stated, knowledge of all things and even practical knowledge, why did He not have omnipotence? Certain Lutherans who are called Ubiquists because of their heresy, say that Christ's humanity as also His divinity is everywhere, and always omnipotent.

First Article: Whether The Soul Of Christ Had Omnipotence In The Absolute Sense

Conclusion. The soul of Christ could not have omnipotence in the absolute sense.

Scriptural proof. It is said of God: "Almighty is His name,"[1266] which means that omnipotence applies only to God.

Theological proof. In the hypostatic union the two natures remained distinct, each retaining its own properties. But omnipotence in the absolute sense is a property of the divine nature. Therefore omnipotence in the absolute sense cannot be attributed to Christ's human nature.

Thus, in created things, operation follows being, and only the divine nature, or the self-subsisting Being, has active omnipotence with respect to everything to which the term "being" can apply, or to which the notion of being is not repugnant. Hence Christ's human nature can neither create, nor produce whatever does not involve contradiction, nor cause itself.

Reply to first objection. Nevertheless, just as, on account of the unity of person in Christ, we can say: "This man, Jesus, is God, " so we can say: "This man is omnipotent, " not because of His human nature, but because there is one person in Christ, who is both God and man.[1267]

Reply to second objection. Although the knowledge of Christ's soul extends to everything present, past, and future, it is not so with His active power, because infinite might is not required for the above-mentioned knowledge, whereas, on the contrary, it is required in creating,[1268] for the most universal effect, namely, absolute being, can be produced only by the most universal cause.

Reply to third objection. "It is not necessary that Christ's soul should have practical knowledge of those things of which it has speculative knowledge." Thus Christ's soul has speculative knowledge of creation, since it knows how God creates, but it has not factual knowledge of creation.

Another objection. Nevertheless Christ said: "All things are delivered to Me by My Father,"[1269] and "All power is given to Me in heaven and in earth."[1270]

Reply. These words are true according to the predication of idioms, just as it is true to say, because of the one person in Christ, "this man is God." Moreover, the above-quoted texts can be understood of Christ as man concerning the power of excellence He had in commanding the preaching of the gospel. Hence Jesus says: "Going therefore teach ye all nations."[1271]

But I insist. According to the teaching of St. Thomas,[1272] there is only one being in Christ, namely, one divine existence, and even Christ's human nature is holy because of His substantial and uncreated holiness. Therefore, on similar grounds, He can be omnipotent.

Reply. The difference here is that omnipotence not only includes divine being, divine sanctity, and divine perfection, but it also implies the infinite mode in which this perfection is in God.

Hence absolute omnipotence is incommunicable. Moreover, divine being and divine holiness are said to be communicated to Christ's human nature because of the person, by means of the terminative but not informing union, for being follows person and where there is one person there is one being. Similarly the human nature is sanctified by the grace of union, inasmuch as it is terminated and possessed by the Word. But omnipotence could not be communicated to the human nature solely in the terminative sense, but only by way of the informing form, that is, as the operative principle, and there is no divine perfection that can be communicated by way of informing form, but only as a terminus; for the informing form is less perfect than the whole of which it is a part. Finally, it is evident that Christ's human nature could not cause itself.

Second Article: Whether Christ's Soul Had Omnipotence With Regard To The Transmutation Of Creatures

State of the Question. This article differs from the first article only in this, that the work of creation is included under omnipotence as discussed in the first article, whereas here we are concerned only with the miraculous transmutation of creatures.

It seems that Christ's soul would be endowed with this omnipotence, because He possessed most fully the grace of miracles which is mentioned among the graces gratis datae, and He also illumined the higher angels, inasmuch as they are ministers in the kingdom of heaven.

Conclusion. Nevertheless St. Thomas says that Christ's soul did not have omnipotence with regard to the transmutation of creatures.

1) General proof. It is taken from the counterargument of this article and may be expressed as follows: To transmute creatures miraculously belongs to Him who has the power to create and preserve them, as explained by St. Thomas.[1273] The reason is that only the most universal cause, which can immediately produce and preserve any universal effect, whether this effect is embedded in material things or separated from matter, can immediately effect a change in it, because this immediate change presupposes the same universality in the cause as this latter immediate production. Thus God alone, who created and preserved things in being, can immediately change being as such by transubstantiation, prime matter by acting immediately on its obediential potency, also immediately change internally the intellect and the will that is ordained to universal good.[1274]

Christ's soul did not have this same universality in causation as the divine nature, and so it cannot be the principal cause of miracles.

2) Particular proof. It is drawn more from the properties of Christ's soul, and is explained by three subordinated conclusions.

First conclusion. Christ's soul, by its own natural or gratuitous power, was able to produce those effects that are befitting to the soul, such as to rule the body, direct human acts and illumine by His plenitude of grace and knowledge even the angels. Nevertheless St. Thomas does not mean to say that Christ's soul is the physical and principal cause of grace, but that it is the moral cause by way of merit, and also, as he immediately remarks afterward, it is the physical and instrumental cause, by its effectiveness.

Second conclusion. Christ's soul, as it is the instrument of the Word, had instrumental power to effect all the miraculous transmutations ordainable to the end of the Incarnation, which is to restore all things either in heaven or on earth.[1275] This is evident from the end of the Incarnation.

Third conclusion. Christ's soul, even as the instrument of the Word, has not the power to annihilate the creature, because annihilation corresponds to creation, which cannot be done by an instrument, because there is no presupposed subject that can be disposed for this action, as was shown above.[1276]

Reply to third objection. Thus Christ had most excellently the grace of working miracles.

The Instrumental Causality Of Christ's Human Nature

The question, whether Christ's human nature is the physical instrument of grace, miracles, and other supernatural effects, or merely the moral instrument, is one that is disputed in the schools of theology, and it finds its place here as an appendix to this article.[1277]

The Thomists maintain that Christ's human nature is a physical instrument, whereas the Scotists hold that it is a moral instrument. There is this same divergence of opinion as regards the causality of the sacraments, which are instruments of grace separated from the divine nature, whereas Christ's human nature is an instrument that is personally united with the divine nature.[1278]

It is presupposed as certain (1) that Christ's human nature is not the principal physical cause of sanctifying grace, because St. Thomas makes it clear that "the gift of grace surpasses every capability of created nature, since it is nothing else than a certain participation in the divine nature.... And thus it is necessary that God alone should deify... just as it is impossible that anything but fire can enkindle."[1279] (2) It is likewise certain that Christ's human nature is also the principal moral cause of grace and miracles, because He merited these by condign merit, and there is no other assignable meritorious cause above Christ.

Therefore the only question is whether Christ's human nature, after the accomplishment of the Incarnation, was not merely the moral cause, but also the physically instrumental cause of grace and miracles, and of other supernatural works that serve the end of the Incarnation.

It is a certainty that before the accomplishment of the Incarnation, Christ's human nature was not the physical cause, but only the moral cause of the grace bestowed on the patriarchs of the Old Testament, because physical operation follows physical being, or the existence of a physical cause. Therefore the question concerns only the influence exerted by Christ's human nature after the Incarnation.

The Thomists unanimously admit that after the completion of the Incarnation, Christ's human nature, either during His life on earth or as He is in heaven, was and is the physically instrumental cause of grace and miracles.

1) This conclusion is at least implied in Sacred Scripture, for the Evangelist says of Christ: "Virtue went out from Him and healed all,"[1280] and Christ says of Himself: "I know that virtue is gone out from Me."[1281] This can scarcely be interpreted as meaning moral power, such as the power of prayer, which, since it is a mental process, can be said only in a very improper sense to go forth from the body.

Likewise, according to the Sacred Scripture, Christ by breathing upon His apostles gave them the Holy Spirit, in a loud voice and commanding tone raised Lazarus to life. All such acts seem to imply a causality that is not moral but physical. Likewise, when Christ says: "The works [miraculous] that I do in the name of My Father, they give testimony of Me."[1282] In other words, it was not only by means of prayer and merit that Jesus obtained the gift of miracles from His Father, but He actually performed them by His own power.

Similarly the First Council of Ephesus defined in its eleventh canon that "Christ's flesh has a vivifying power because of its union with the Word."[1283] But Christ's flesh cannot have vivifying power morally by way of merit or prayer; therefore the power must be physical. Likewise, in the liturgy it is said of Christ's body in the Eucharist, that it is "a living and vital bread,"[1284] namely, a feeding and nourishing grace; therefore it produces graces not morally but physically.

But these quotations from Sacred Scripture and the councils are to be taken in their proper and obvious sense, according to the commonly accepted rule, unless anything unbefitting results therefrom. However, the words "healing power has gone forth from the body..., to do, to operate, to vivify, " in their proper and obvious sense denote physically instrumental causality, and, as will at once be seen, nothing unbefitting results therefrom.

Authoritative proof from St. Thomas. In this second article he says: "If we speak of the soul of Christ as it is the instrument of the Word united to Him, it had an instrumental power to effect all the miraculous transmutations ordainable to the end of the Incarnation." Evidently it is a question here not of moral causality that operates by way of merit or prayer, but of physical causality. St. Thomas, in speaking of Christ as head of the Church, taught that He causes grace both meritoriously and efficiently.[1285]

To be sure, Christ's passion is now something of the past, but does it not virtually persist in the scars remaining from the wounds? Hence the physically instrumental cause is now Christ's human nature qualifiedly changed by His passion. Moreover, there remains in Christ's soul that willingness by which He offered Himself and by which "He is always living to make intercession for us,"[1286] in that, as the Council of Trent says in its treatise on the Sacrifice of the Mass, "the same victim is now offering by the ministry of His priests, who then offered Himself on the cross."[1287]

Theological proof. To act not only morally but also physically is more perfect than merely moral action, so that a physical concurrence that truly produces its effect is more perfect than moral concurrence, by which the effect is obtained only by way of merit or prayer. But it must be admitted that Christ's human nature is more perfect if it proves to be compatible either in itself, or to the end of the Incarnation. Therefore, it must be conceded that Christ's human nature is the physically instrumental cause of supernatural effects that serve the end of the Incarnation.

Confirmation. According to the traditional terminology of the Fathers and theologians, Christ's human nature is the physical instrument of His divine nature in the production of grace and the working of miracles. It is not, however, the moral instrument, for Christ is the principal moral cause of the effects, inasmuch as there is no assignable meritorious cause above Him. Therefore Christ's human nature is the physical instrument, provided the distinction is drawn between physical and moral, to the exclusion of either metaphysical or spiritual.

Solution of objections.

First objection. An instrument must really contact the subject upon which it acts. But Christ's human nature, since it is now in heaven, does not really contact us in the production of our grace. Therefore Christ's human nature is not the instrument of our grace.

Reply. I distinguish the major: an instrument must really contact the subject upon which it acts, by virtual contact, this I concede; by quantitative and personal contact, this I deny. Thus a trumpet is a physical instrument for the transmission of sound, yet it does not touch the ears of the hearers. So also the sun illumines and heats the earth from on high, and the magnet attracts iron to itself from a distance. I contradistinguish the minor; Christ's human nature as now existing in heaven does not really contact us, by His quantitative and personal contact, this I concede; by a virtual contact, that I deny.

There is no difficulty in this, especially for instruments made use of by divine power, in virtue of which all things that must be changed are made present to omnipresent omnipotence. Moreover, the superior part of Christ's soul is not itself located, and thus it is not locally distant from our souls. Finally, Christ's soul is united to God, and also our soul is united to God, although in a different way.[1288]

Second objection. An instrument, that it be not purely a medium, must by its own action have a disposing influence in producing the effect of the principal agent. But Christ's human nature cannot thus be a disposing influence, by producing some disposition for grace or for a miraculous effect. We can in no way conceive what would be the nature of this previous disposition.

Reply. I distinguish the major: that an instrument must by its own action exert a disposing influence on the manner of operating of the principal agent, this I concede; thus a trumpet reinforces and directs the sound in the mode of its transmission; that an instrument always produces something objectively real that is the result of its action, this I deny; some instruments do so, such as a pen that deposits ink on the paper, but not all instruments, such as a trumpet, act in this manner.

Thus an instrument does not have to produce in the subject to be changed some prior effect or previous disposition. It suffices that the instrument operates by disposing the subject that must undergo a change. Thus Christ's human nature had and has its own action as regards miracles and grace, for instance, operating by means of words, signs, gestures, acts of the will, and other ways. Thus it is a disposing influence in the production of the divine effect at this particular time and place, for example, the healing of this particular man, of this particular disease in preference to some other disease.

Third objection. An instrument must receive its power from the principal cause, so as to be capable of producing the effect that surpasses its own power. But the power derived from the principal cause in Christ's human nature is either spiritual, and as such it cannot be received in Christ's flesh, or else it is corporeal, and consequently cannot produce grace. Therefore Christ's human nature cannot be the instrument of the principal cause in His operations.

Reply. I distinguish the major: that an instrument must receive transient power, or rather a transient motion from the principal cause, this I concede; a permanent motion, this I deny. I contradistinguish the minor: that this power is spiritual and cannot be in Christ's flesh as a permanent motion, let this pass without comment; as a transient motion, this I deny, because this transient motion is proportioned rather to the term of the action than to the subject of the action.

Explanation. This instrumental motion, however, as being something transient, differs completely from permanent power. For a permanent power is strictly for the benefit of the subject in which it inheres; hence it is proportioned to this subject. On the contrary, a transient motion, although it is in the instrument, since it is an accident, nevertheless, as it is formally transient, tending to produce the term of the action, must be proportioned preferably to the subject of inhesion. Thus, from the expression of a man's countenance, from the tone of his voice, and the manner of his utterance, something spiritual goes forth that is adapted to the hearer so that we say: a few words suffice to the wise.

In fact, this transient motion, also as a spiritual accident, is not received in Christ's body, inasmuch as Christ's body is formally something corporeal, but inasmuch as it is a being, for it is received in His body because of its obediential capacity, which applies to created things under the general notion of being and created substance. God makes use of bodies inasmuch as they are beings.

Finally, there seems to be nothing repugnant in the idea of a spiritual power being subjected to what is corporeal, inasmuch as the body is born to obey the spirit. Thus the rational soul, although it is spiritual, is dependent on the body, which it controls rather than being controlled by the body. Likewise the moral virtues of temperance and fortitude, although they are spiritual and infused virtues, are dependent on the sensitive faculties of the soul, which are intrinsically dependent on the animal organism.

Thus it befits Christ's human nature to be the physically instrumental cause of grace and miracles or of effects that serve the end of the Incarnation, as St. Thomas says in the present article. To exert one's influence on beings in both the moral and the physical orders shows greater perfection than to manifest it merely in the moral order, and therefore this greater perfection must be conceded to Christ as man.

This is a better way of illustrating what was said above concerning Christ's headship[1289] and His influence on the members of His Church in the production of both habitual and actual grace.

Third Article: Whether Christ's Soul Had Omnipotence With Regard To His Own Body

Reply. Christ's soul in its proper nature and power was incapable of changing the natural disposition of its body, so that it could not have the effect of exempting the body from the laws of gravitation or of the necessity of taking food, or of feeling the blows inflicted on it. The reason is that the soul of its own nature has a determinate relation to its own body. Christ's soul, although it was already beatified, had assumed a passible body, namely, a body that conformed to the conditions of passibility.[1290]

Christ's soul, however, inasmuch as it was the instrument of the Word, could miraculously change the natural disposition of its body, so that the body was not subject to the laws of gravitation, or did not suffer from the blows and wounds inflicted on it. So also Christ miraculously preserved several martyrs from physical pain.

Fourth Article: Whether Christ's Soul Had Omnipotence As Regards The Execution Of His Will

Reply. (1) Christ's soul was able by its own power to bring about absolutely whatever was willed for it; but Christ, in His wisdom, did not will absolutely that it should by its own power do what surpassed it, for there could have been no presumption in Christ.

2) Christ's soul, as the instrument of the Word, could do whatever it absolutely willed was to be accomplished by divine power, such as the resurrection of its own body. But it could will in this way only what God had efficaciously decreed, and it knew these decrees.[1291]

Was Christ's prayer always heard? The prayer He made according to His absolute will, was always heard, but not the prayer that was conditional, such as when He said: "If it be possible, let this chalice pass from Me."[1292]

St. Thomas says farther on: "Christ willed nothing but what He knew God to will. Wherefore every absolute will of Christ, even human, was fulfilled, because it was in conformity with God."[1293]

It is manifestly a sign of imprudence to will absolutely and efficaciously what certainly cannot come to pass. But Christ, as stated, certainly knew all future things by the beatific vision. Therefore He did not will absolutely and efficaciously what was not to be done either by His own power or by means of others.[1294]

This concludes the question of Christ's power, and now we must consider antithetically the defects of Christ's human nature inasmuch as it was passible before the Resurrection.CHAPTER XV: QUESTION 13: THE POWER OF CHRIST'S SOUL

If Christ had, as stated, knowledge of all things and even practical knowledge, why did He not have omnipotence? Certain Lutherans who are called Ubiquists because of their heresy, say that Christ's humanity as also His divinity is everywhere, and always omnipotent.

First Article: Whether The Soul Of Christ Had Omnipotence In The Absolute Sense

Conclusion. The soul of Christ could not have omnipotence in the absolute sense.

Scriptural proof. It is said of God: "Almighty is His name,"[1266] which means that omnipotence applies only to God.

Theological proof. In the hypostatic union the two natures remained distinct, each retaining its own properties. But omnipotence in the absolute sense is a property of the divine nature. Therefore omnipotence in the absolute sense cannot be attributed to Christ's human nature.

Thus, in created things, operation follows being, and only the divine nature, or the self-subsisting Being, has active omnipotence with respect to everything to which the term "being" can apply, or to which the notion of being is not repugnant. Hence Christ's human nature can neither create, nor produce whatever does not involve contradiction, nor cause itself.

Reply to first objection. Nevertheless, just as, on account of the unity of person in Christ, we can say: "This man, Jesus, is God, " so we can say: "This man is omnipotent, " not because of His human nature, but because there is one person in Christ, who is both God and man.[1267]

Reply to second objection. Although the knowledge of Christ's soul extends to everything present, past, and future, it is not so with His active power, because infinite might is not required for the above-mentioned knowledge, whereas, on the contrary, it is required in creating,[1268] for the most universal effect, namely, absolute being, can be produced only by the most universal cause.

Reply to third objection. "It is not necessary that Christ's soul should have practical knowledge of those things of which it has speculative knowledge." Thus Christ's soul has speculative knowledge of creation, since it knows how God creates, but it has not factual knowledge of creation.

Another objection. Nevertheless Christ said: "All things are delivered to Me by My Father,"[1269] and "All power is given to Me in heaven and in earth."[1270]

Reply. These words are true according to the predication of idioms, just as it is true to say, because of the one person in Christ, "this man is God." Moreover, the above-quoted texts can be understood of Christ as man concerning the power of excellence He had in commanding the preaching of the gospel. Hence Jesus says: "Going therefore teach ye all nations."[1271]

But I insist. According to the teaching of St. Thomas,[1272] there is only one being in Christ, namely, one divine existence, and even Christ's human nature is holy because of His substantial and uncreated holiness. Therefore, on similar grounds, He can be omnipotent.

Reply. The difference here is that omnipotence not only includes divine being, divine sanctity, and divine perfection, but it also implies the infinite mode in which this perfection is in God.

Hence absolute omnipotence is incommunicable. Moreover, divine being and divine holiness are said to be communicated to Christ's human nature because of the person, by means of the terminative but not informing union, for being follows person and where there is one person there is one being. Similarly the human nature is sanctified by the grace of union, inasmuch as it is terminated and possessed by the Word. But omnipotence could not be communicated to the human nature solely in the terminative sense, but only by way of the informing form, that is, as the operative principle, and there is no divine perfection that can be communicated by way of informing form, but only as a terminus; for the informing form is less perfect than the whole of which it is a part. Finally, it is evident that Christ's human nature could not cause itself.

It seems that Christ's soul would be endowed with this omnipotence, because He possessed most fully the grace of miracles which is mentioned among the graces gratis datae, and He also illumined the higher angels, inasmuch as they are ministers in the kingdom of heaven.

Second conclusion. Christ's soul, as it is the instrument of the Word, had instrumental power to effect all the miraculous transmutations ordainable to the end of the Incarnation, which is to restore all things either in heaven or on earth.[1275] This is evident from the end of the Incarnation.

Third conclusion. Christ's soul, even as the instrument of the Word, has not the power to annihilate the creature, because annihilation corresponds to creation, which cannot be done by an instrument, because there is no presupposed subject that can be disposed for this action, as was shown above.[1276]

Reply to third objection. Thus Christ had most excellently the grace of working miracles.

It is a certainty that before the accomplishment of the Incarnation, Christ's human nature was not the physical cause, but only the moral cause of the grace bestowed on the patriarchs of the Old Testament, because physical operation follows physical being, or the existence of a physical cause. Therefore the question concerns only the influence exerted by Christ's human nature after the Incarnation.

However, the words "healing power has gone forth from the body..., to do, to operate, to vivify, " in their proper and obvious sense denote physically instrumental causality, and, as will at once be seen, nothing unbefitting results therefrom.

Authoritative proof from St. Thomas. In this second article he says: "If we speak of the soul of Christ as it is the instrument of the Word united to Him, it had an instrumental power to effect all the miraculous transmutations ordainable to the end of the Incarnation." Evidently it is a question here not of moral causality that operates by way of merit or prayer, but of physical causality.

To be sure, Christ's passion is now something of the past, but does it not virtually persist in the scars remaining from the wounds? Hence the physically instrumental cause is now Christ's human nature qualifiedly changed by His passion. Moreover, there remains in Christ's soul that willingness by which He offered Himself and by which "He is always living to make intercession for us,"[1286] in that, as the Council of Trent says in its treatise on the Sacrifice of the Mass, "the same victim is now offering by the ministry of His priests, who then offered Himself on the cross."[1287]

Theological proof. To act not only morally but also physically is more perfect than merely moral action, so that a physical concurrence that truly produces its effect is more perfect than moral concurrence, by which the effect is obtained only by way of merit or prayer.

It is not, however, the moral instrument, for Christ is the principal moral cause of the effects, inasmuch as there is no assignable meritorious cause above Him. Therefore Christ's human nature is the physical instrument, provided the distinction is drawn between physical and moral, to the exclusion of either metaphysical or spiritual.

Solution of objections.

First objection. An instrument must really contact the subject upon which it acts. But Christ's human nature, since it is now in heaven, does not really contact us in the production of our grace. Therefore Christ's human nature is not the instrument of our grace.

Reply. I distinguish the major: an instrument must really contact the subject upon which it acts, by virtual contact, this I concede; by quantitative and personal contact, this I deny. Thus a trumpet is a physical instrument for the transmission of sound, yet it does not touch the ears of the hearers.

There is no difficulty in this, especially for instruments made use of by divine power, in virtue of which all things that must be changed are made present to omnipresent omnipotence. Moreover, the superior part of Christ's soul is not itself located, and thus it is not locally distant from our souls. Finally, Christ's soul is united to God, and also our soul is united to God, although in a different way.[1288]

Second objection. An instrument, that it be not purely a medium, must by its own action have a disposing influence in producing the effect of the principal agent. But Christ's human nature cannot thus be a disposing influence, by producing some disposition for grace or for a miraculous effect. We can in no way conceive what would be the nature of this previous disposition.

Reply. I distinguish the major: that an instrument must by its own action exert a disposing influence on the manner of operating of the principal agent, this I concede; thus a trumpet reinforces and directs the sound in the mode of its transmission; that an instrument always produces something objectively real that is the result of its action, this I deny; some instruments do so, such as a pen that deposits ink on the paper, but not all instruments, such as a trumpet, act in this manner.

Thus an instrument does not have to produce in the subject to be changed some prior effect or previous disposition. It suffices that the instrument operates by disposing the subject that must undergo a change. Thus Christ's human nature had and has its own action as regards miracles and grace, for instance, operating by means of words, signs, gestures, acts of the will, and other ways. Thus it is a disposing influence in the production of the divine effect at this particular time and place, for example, the healing of this particular man, of this particular disease in preference to some other disease.

Third objection. An instrument must receive its power from the principal cause, so as to be capable of producing the effect that surpasses its own power. But the power derived from the principal cause in Christ's human nature is either spiritual, and as such it cannot be received in Christ's flesh, or else it is corporeal, and consequently cannot produce grace. Therefore Christ's human nature cannot be the instrument of the principal cause in His operations.

Reply. I distinguish the major: that an instrument must receive transient power, or rather a transient motion from the principal cause, this I concede; a permanent motion, this I deny. I contradistinguish the minor: that this power is spiritual and cannot be in Christ's flesh as a permanent motion, let this pass without comment; as a transient motion, this I deny, because this transient motion is proportioned rather to the term of the action than to the subject of the action.

Explanation. This instrumental motion, however, as being something transient, differs completely from permanent power. For a permanent power is strictly for the benefit of the subject in which it inheres; hence it is proportioned to this subject. On the contrary, a transient motion, although it is in the instrument, since it is an accident, nevertheless, as it is formally transient, tending to produce the term of the action, must be proportioned preferably to the subject of inhesion. Thus, from the expression of a man's countenance, from the tone of his voice, and the manner of his utterance, something spiritual goes forth that is adapted to the hearer so that we say: a few words suffice to the wise.

In fact, this transient motion, also as a spiritual accident, is not received in Christ's body, inasmuch as Christ's body is formally something corporeal, but inasmuch as it is a being, for it is received in His body because of its obediential capacity, which applies to created things under the general notion of being and created substance. God makes use of bodies inasmuch as they are beings.

Finally, there seems to be nothing repugnant in the idea of a spiritual power being subjected to what is corporeal, inasmuch as the body is born to obey the spirit. Thus the rational soul, although it is spiritual, is dependent on the body, which it controls rather than being controlled by the body. Likewise the moral virtues of temperance and fortitude, although they are spiritual and infused virtues, are dependent on the sensitive faculties of the soul, which are intrinsically dependent on the animal organism.

Thus it befits Christ's human nature to be the physically instrumental cause of grace and miracles or of effects that serve the end of the Incarnation, as St. Thomas says in the present article. To exert one's influence on beings in both the moral and the physical orders shows greater perfection than to manifest it merely in the moral order, and therefore this greater perfection must be conceded to Christ as man.

This is a better way of illustrating what was said above concerning Christ's headship[1289] and His influence on the members of His Church in the production of both habitual and actual grace.

Third Article: Whether Christ's Soul Had Omnipotence With Regard To His Own Body

Reply. Christ's soul in its proper nature and power was incapable of changing the natural disposition of its body, so that it could not have the effect of exempting the body from the laws of gravitation or of the necessity of taking food, or of feeling the blows inflicted on it. The reason is that the soul of its own nature has a determinate relation to its own body. Christ's soul, although it was already beatified, had assumed a passible body, namely, a body that conformed to the conditions of passibility.[1290]

Christ's soul, however, inasmuch as it was the instrument of the Word, could miraculously change the natural disposition of its body, so that the body was not subject to the laws of gravitation, or did not suffer from the blows and wounds inflicted on it. So also Christ miraculously preserved several martyrs from physical pain.

Fourth Article: Whether Christ's Soul Had Omnipotence As Regards The Execution Of His Will

Reply. (1) Christ's soul was able by its own power to bring about absolutely whatever was willed for it; but Christ, in His wisdom, did not will absolutely that it should by its own power do what surpassed it, for there could have been no presumption in Christ.

2) Christ's soul, as the instrument of the Word, could do whatever it absolutely willed was to be accomplished by divine power, such as the resurrection of its own body. But it could will in this way only what God had efficaciously decreed, and it knew these decrees.[1291]

Was Christ's prayer always heard? The prayer He made according to His absolute will, was always heard, but not the prayer that was conditional, such as when He said: "If it be possible, let this chalice pass from Me."[1292]

St. Thomas says farther on: "Christ willed nothing but what He knew God to will. Wherefore every absolute will of Christ, even human, was fulfilled, because it was in conformity with God."[1293]

It is manifestly a sign of imprudence to will absolutely and efficaciously what certainly cannot come to pass. But Christ, as stated, certainly knew all future things by the beatific vision. Therefore He did not will absolutely and efficaciously what was not to be done either by His own power or by means of others.[1294]

This concludes the question of Christ's power, and now we must consider antithetically the defects of Christ's human nature inasmuch as it was passible before the Resurrection.
