Chapter XIV. The Union Of The Two Natures Constituting The Person Of The Mediator

Chapter XIV. The Union Of The Two Natures Constituting The Person Of The Mediator.

When it is said that “the Word was made flesh,”1170 this is not to be understood as if the Word was transmuted into flesh, or blended with flesh. Choosing from the womb of the Virgin a temple for his residence, he who was the Son of God, became also the Son of man, not by a confusion of substance, but by a unity of person. For we assert such a connection and union of the Divinity with the humanity, that each nature retains its properties entire, and yet both together constitute one Christ. If any thing among men can be found to resemble so great a mystery, man himself appears to furnish the most apposite similitude; being evidently composed of two substances, of which, however, neither is so confounded with the other, as not to retain its distinct nature. For the soul is not the body, nor is the body the soul. Wherefore that is predicated separately of the soul, which cannot be at all applied to the body. On the contrary, that is predicated of the body, which is totally incompatible with the soul. And that is predicated of the whole man, which cannot with propriety be understood either of the soul or of the body alone. Lastly, the properties of the soul are transferred to the body, and the properties of the body to the soul; yet he that is composed of these two parts is no more than one man. Such forms of expression signify that there is in man one person composed of two distinct parts; and that there are two different natures united in him to constitute that one person. The Scriptures speak in a similar manner respecting Christ. They attribute to him, sometimes those things which are applicable merely to his humanity; sometimes those things which belong peculiarly to his Divinity; and not unfrequently those things which comprehend both his natures, but are incompatible with either of them alone. And this union of the two natures in Christ they so carefully maintain, that they sometimes attribute to one what belongs to the other—a mode of expression which the ancient writers called a communication of properties.

II. These things might be liable to objection, if the Scripture did not abound with passages, which prove that none of them is of human invention. What Christ asserted concerning himself, “Before Abraham was, I am,”1171 was very inapplicable to his humanity. I am aware of the cavil with which erroneous spirits would corrupt this passage,—that he was before all ages, because he was even then foreknown as the Redeemer, as well in the decree of the Father, as in the minds of the faithful. But as he clearly distinguishes the day of his manifestation from his eternal essence, and professedly urges his antiquity, in proof of his possessing an authority in which he excels Abraham, there is no doubt that he challenges to himself what is peculiar to the Deity. Paul asserts him to be “the first-born of every creature, that he is before all things, and that by him all things consist:”1172 he declares himself, that he “had a glory with the Father before the world was,”1173 and that he coöperates with the Father.1174 These things are equally incompatible with humanity. It is certain that these, and such as these, are peculiar attributes of Divinity. But when he is called the “servant” of the Father;1175 when it is stated that he “increased in wisdom and stature, and in favour with God and man;”1176 that he seeks not his own glory; that he knows not the last day; that he speaks not of himself; that he does not his own will; that he was seen and handled;1177 all this belongs solely to his humanity. For as he is God, he is incapable of any augmentation whatever; he does all things for his own glory, and there is nothing concealed from him; he does all things according to the decision of his own will, and is invisible and intangible. And yet he ascribes these things not to his human nature separately, but to himself, as though they belonged to the person of the Mediator. But the communication of properties is exemplified in the assertion of Paul that “God purchased the Church with his own blood,”1178 and that “the Lord of glory” was “crucified.”1179 Also in what John says, that they had “handled the Word of life.”1180 God has no blood; he is not capable of suffering, or of being touched with hands; but since he, who was at once the true God and the man Christ Jesus, was crucified and shed his blood for us, those things which were performed in his human nature are improperly, yet not without reason, transferred to the Divinity. There is a similar example of this, where John teaches us, that “God laid down his life for us.”1181 There also the property of the humanity is transferred to the other nature. Again, when Christ, while he still lived on the earth, said, “No man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven:”1182 as man, and in the body which he had assumed, he certainly was not at that time in heaven, but because he was both God and man, on account of the union of both natures, he attributed to one what belonged to the other.

III. But the clearest of all the passages declarative of the true substance of Christ are those which comprehend both the natures together; such as abound in the Gospel of John. For it is not with exclusive reference to the Deity or the humanity, but respecting the complex person composed of both, that we find it there stated; that he has received of the Father power to forgive sins, to raise up whom he will, to bestow righteousness, holiness, and salvation; that he is appointed to be the Judge of the living and the dead, that he may receive the same honour as the Father;1183 finally, that he is “the light of the world,” “the good shepherd,” “the only door,” “the true vine.”1184 For with such prerogatives was the Son of God invested at his manifestation in the flesh; which although he enjoyed with the Father before the creation of the world, yet not in the same manner or on the same account; and which could not be conferred on a mere man. In the same sense also it is reasonable to understand the declaration of Paul, that after the last judgment Christ “shall deliver up the kingdom to God, even the Father.”1185 Now, the kingdom of the Son of God, which had no beginning, will never have any end. But as he concealed himself under the meanness of the flesh, and humbled himself by assuming the form of a servant, and laid aside his external majesty in obedience to the Father,1186 and after having undergone this humiliation, was at length crowned with glory and honour, and exalted to supreme dominion,1187 that before him “every knee should bow;”1188 so he shall then surrender to the Father that name and crown of glory, and all that he has received from the Father, “that God may be all in all.”1189 For why has power and dominion been given to him, but that the Father may rule us by his hand? In this sense he is also said to sit at the right hand of the Father. But this is only temporary, till we can enjoy the immediate contemplation of the Deity. And here it is impossible to excuse the error of the ancients, who, for want of sufficient attention to the person of the Mediator, obscure the genuine sense of almost all the doctrine which we have in the Gospel of John, and involve themselves in many difficulties. Let this maxim, then, serve us as a key to the true sense, that those things which relate to the office of the Mediator, are not spoken simply of his Divine or of his human nature. Christ therefore will reign, till he comes to judge the world, forasmuch as he connects us with the Father as far as is compatible with our infirmity. But when we shall participate the glory of heaven, and see God as he is, then, having fulfilled the office of Mediator, he will cease to be the ambassador of the Father, and will be content with that glory which he enjoyed before the creation of the world. Nor is the title of Lord peculiarly applied to the person of Christ in any other respect, than as it marks an intermediate station between God and us. This is the meaning of that expression of Paul, “One God, of whom are all things; and one Lord, by whom are all things;”1190 namely, to whom the Father has committed a temporary dominion, till we shall be admitted to the immediate presence of his Divine majesty; which will be so far from sustaining any diminution by his surrender of the kingdom to the Father, that it will exhibit itself in far superior splendour. For then also God will cease to be the head of Christ, because the Deity of Christ himself, which is still covered with a veil, will shine forth in all its native effulgence.

IV. And this observation, if the reader make a judicious application of it, will be of great use towards the solution of many difficulties. For it is surprising how much ignorant persons, and even some who are not altogether destitute of learning, are perplexed by such forms of expression, as they find attributed to Christ, which are not exactly appropriate either to his Divinity or to his humanity. This is for want of considering that they are applicable to his complex person, consisting of God and man, and to his office of Mediator. And indeed we may see the most beautiful coherence between all these things, if they have only a sober expositor, to examine such great mysteries with becoming reverence. But these furious and frantic spirits throw every thing into confusion. They lay hold of the properties of his humanity, to destroy his Divinity; on the other hand, they catch at the attributes of his Divinity, to destroy his humanity; and by what is spoken of both natures united, but is applicable separately to neither, they attempt to destroy both. Now, what is this but to contend that Christ is not man, because he is God; that he is not God, because he is man; and that he is neither man nor God, because he is at once both man and God? We conclude, therefore, that Christ, as he is God and man, composed of these two natures united, yet not confounded, is our Lord and the true Son of God, even in his humanity; though not on account of his humanity. For we ought carefully to avoid the error of Nestorius, who, attempting rather to divide than to distinguish the two natures, thereby imagined a double Christ. This we find clearly contradicted by the Scripture, where the appellation of “the Son of God” is given to him who was born of the Virgin, and the Virgin herself is called “the mother of our Lord.”1191 We must also beware of the error of Eutyches, lest while we aim to establish the unity of Christ's person, we destroy the distinction of his two natures. For we have already cited so many testimonies, where his Divinity is distinguished from his humanity, and the Scripture abounds with so many others, that they may silence even the most contentious. I shall shortly subjoin some, in order to a more complete refutation of that notion. At present one passage shall suffice us; for Christ would not have styled his body “a temple,”1192 if it had not been the residence of the Divinity, and at the same time distinct from it. Wherefore, as Nestorius was justly condemned in the council of Ephesus, so also was Eutyches afterwards in the councils of Constantinople and Chalcedon; for to confound the two natures in Christ, and to separate them, are equally wrong.

V. But in our time also there has arisen a heretic equally pestilent, Michael Servetus, who in the place of the Son of God has substituted an imaginary being composed of the essence of God, spirit, flesh, and three uncreated elements. In the first place, he denies Christ to be the Son of God, in any other respect than as he was begotten by the Holy Spirit in the womb of the Virgin. But his subtlety tends to subvert the distinction of the two natures, and thereby to represent Christ as something composed of God and man, and yet neither God nor man. For this is the principal point which he constantly endeavours to establish, that before Christ was manifested in the flesh, there were in God only some shadowy figures; the truth or effect of which had no real existence till the Word, who had been destined to this honour, actually began to be the Son of God. Now, we confess that the Mediator, who was born of the Virgin, is properly the Son of God. Nor indeed could the man Christ be a mirror of the inestimable grace of God, if this dignity had not been conferred on him, to be, and to be called, “the only begotten Son of God.” The doctrine of the Church, however, remains unshaken, that he is accounted the Son of God, because, being the Word begotten by the Father before all ages, he assumed the human nature in a hypostatical union. By the “hypostatical union” the ancients expressed the combination of two natures constituting one person. It was invented to refute the error of Nestorius, who imagined the Son of God to have dwelt in flesh in such a manner as, notwithstanding that, to have had no real humanity. Servetus falsely accuses us of making two Sons of God, when we say that the eternal Word was the Son of God, before he was clothed with flesh; as though we affirmed any other than that he was manifested in the flesh. For if he was God before he became man, it is not to be inferred that he began to be a new God. There is no more absurdity in affirming that the Son of God appeared in the flesh, who nevertheless was always the Son of God by eternal generation. This is implied in the words of the angel to Mary: “That holy thing which shall be born of thee shall be called the Son of God;”1193 as though he had said, that the name of the Son, which had been in obscurity under the law, was about to be celebrated and universally known. Consistent with this is the representation of Paul; that through Christ we are the sons of God, and may freely and confidently cry, Abba, Father.1194 But were not the holy patriarchs in ancient times numbered among the children of God? Yes; and depending on this claim, they invoked God as their Father. But because, since the introduction of the only begotten Son of God into the world, the celestial paternity has been more clearly revealed, Paul mentions this as the privilege of the kingdom of Christ. It must, however, be steadily maintained, that God never was a Father, either to angels or to men, but with reference to his only begotten Son; and especially that men, whom their own iniquity renders odious to God, are his sons by gratuitous adoption, because Christ is his Son by nature. Nor is there any force in the cavil of Servetus, that this depends on the filiation which God has decreed in himself; because we are not here treating of figures, as expiation was represented by the blood of the sacrifices: but as they could not be the sons of God in reality, unless their adoption were founded on this head, it is unreasonable to detract from the head, that which is common to all the members. I go further: since the Scripture calls angels “the children of God,”1195 whose enjoyment of such high dignity depended not on the future redemption, yet it is necessary that Christ should precede them in order, seeing it is by him that they are connected with the Father. I will briefly repeat this observation, and apply the same to the human race. Since angels and men were originally created in such a condition, that God was the common Father of both, if there be any truth in the assertion of Paul, “that Christ was before all things, the head of the body, and the first-born of every creature, that in all things he might have the preëminence,”1196 I conceive I am right in concluding, that he was also the Son of God before the creation of the world.
