The heads of this chapter are, I. The orthodoxy doctrine as to the true humanity of our Saviour, proved from many passages of Scripture, sec. 1. II. Refutation of the impious objections of the Marcionites, Manichees, and similar heretics, sec. 2–4.
1. Proof of the true humanity of Christ, against the Manichees and Marcionites.
2. Impious objections of heretics further discussed. Six objections answered.
3. Other eight objections answered.
4. Other three objections answered.
1. Of the divinity of Christ, which has elsewhere been established by clear and solid proofs, I presume it were superfluous again to treat. It remains, therefore, to see how, when clothed with our flesh, he fulfilled the office of Mediator. In ancient times, the reality of his human nature was impugned by the Manichees and Marcionites, the latter figuring to themselves a phantom instead of the body of Christ, and the former dreaming of his having been invested with celestial flesh. The passages of Scripture contradictory to both are numerous and strong. The blessing is not promised in a heavenly seed, or the mask of a man, but the seed of Abraham and Jacob; nor is the everlasting throne promised to an aerial man, but to the Son of David, and the fruit of his loins. Hence, when manifested in the flesh, he is called the Son of David and Abraham, not because he was born of a virgin, and yet created in the air, but because, as Paul explains, he was “made of the seed of David, according to the flesh,” (Rom. 1:3), as the same apostle elsewhere says, that he came of the Jews (Rom. 9:5). Wherefore, our Lord himself not contented with the name of man, frequently calls himself the Son of man, wishing to express more clearly that he was a man by true human descent. The Holy Spirit having so often, by so many organs, with so much care and plainness, declared a matter which in itself is not abstruse, who could have thought that mortals would have had the effrontery to darken it with their glosses? Many other passages are at hand, were it wished to produce more: for instance, that one of Paul, that “God sent forth his Son, made of a woman,” (Gal. 4:4), and innumerable others, which show that he was subject to hunger, thirst, cold, and the other infirmities of our nature. But from the many we must chiefly select those which may conduce to build up our minds in true faith, as when it is said, “Verily, he took not on him the nature of angels, but he took on him the seed of Abraham,” “that through death he might destroy him that had the power of death,” (Heb. 2:16, 14). Again, “Both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren.” “Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest.” (Heb. 2:11, 17). Again “We have not an high priest which cannot be touched with the feeling of our infirmities,” (Heb. 4:15), and the like. To the same effect is the passage to which we lately referred, in which Paul distinctly declares, that the sins of the world behoved to be expiated in our flesh (Rom. 8:3). And certainly every thing which the Father conferred on Christ pertains to us for this reason, that “he is the head,” that from him the whole body is “fitly joined together, and compacted by that which every joint supplieth,” (Eph. 4:16). Nay, in no other way could it hold true as is said, that the Spirit was given to him without measure (John 1:16), and that out of his fulness have all we received; since nothing could be more absurd than that God, in his own essence, should be enriched by an adventitious gift. For this reason also, Christ himself elsewhere says, “For their sakes I sanctify myself,” (John 17:19).
2. The passages which they produce in confirmation of their error are absurdly wrested, nor do they gain any thing by their frivolous subtleties when they attempt to do away with what I have now adduced in opposition to them. Marcion imagines that Christ, instead of a body, assumed a phantom, because it is elsewhere said, that he was made in the likeness of man, and found in fashion as a man. Thus he altogether overlooks what Paul is then discussing (Phil. 2:7). His object is not to show what kind of body Christ assumed, but that, when he might have justly asserted his divinity he was pleased to exhibit nothing but the attributes of a mean and despised man. For, in order to exhort us to submission by his example, he shows, that when as God he might have displayed to the world the brightness of his glory, he gave up his right, and voluntarily emptied himself; that he assumed the form of a servant, and, contented with that humble condition, suffered his divinity to be concealed under a veil of flesh. Here, unquestionably, he explains not what Christ was, but in what way he acted. Nay, from the whole context it is easily gathered, that it was in the true nature of man that Christ humbled himself. For what is meant by the words, he was “found in fashion as a man,” but that for a time, instead of being resplendent with divine glory, the human form only appeared in a mean and abject condition? Nor would the words of Peter, that he was “put to death in the flesh, but quickened by the Spirits” (1 Pet. 3:18), hold true, unless the Son of God had become weak in the nature of man. This is explained more clearly by Paul, when he declares that “he was crucified through weakness,” (2 Cor. 13:4). And man, that he might make us sons of God, the expression does not extend to all classes of persons; the intervention of faith being necessary to our being spiritually ingrafted into the body of Christ. A dispute is also ignorantly raised as to the term first-born. It is alleged that Christ ought to have been the first son of Adam, in order that he might be the first-born among the brethren (Rom. 8:29). But primogeniture refers not to age, but to degree of honour and pre-eminence of virtue. There is just as little colour for the frivolous assertion that Christ assumed the nature of man, and not that of angels (Heb. 2:16), because it was the human race that he restored to favour. The apostle, to magnify the honour which Christ has conferred upon us, contrasts us with the angels, to whom we are in this respect preferred. And if due weight is given to the testimony of Moses (Gen. 3:15), when he says that the seed of the woman would bruise the head of the serpent, the dispute is at an end. For the words there used refer not to Christ alone, but to the whole human race. Since the victory was to be obtained for us by Christ, God declares generally, that the posterity of the woman would overcome the devil. From this it follows, that Christ is a descendant of the human race, the purpose of God in thus addressing Eve being to raise her hopes, and prevent her from giving way to despair.
3. The passages in which Christ is called the seed of Abraham, and the fruit of the loins of David, those persons, with no less folly than wickedness, wrap up in allegory. Had the term seed been used allegorically, Paul surely would not have omitted to notice it, when he affirms clearly, and without figure, that the promise was not given “to seeds, as of many; but as of one, And to thy seed, which is Christ,” (Gal. 3:16). With similar absurdity they pretend that he was called the Son of David for no other reason but because he had been promised, and was at length in due time manifested. For Paul, after he had called him the Son of David, by immediately subjoining “according to the flesh”, certainly designates his nature. So also (Rom. 9:5), while declaring him to be “God blessed for ever,” he mentions separately, that, “as concerning the flesh, he was descended from the Jews.” Again if he had not been truly begotten of the seed of David, what is the meaning of the expression, that he is the “fruit of his loins;” or what the meaning of the promise, “Of the fruit of thy body will I set upon thy throne?” (Ps. 132:11). Moreover their mode of dealing with the genealogy of Christ, as given by Matthew, is mere sophistry; for though he reckons up the progenitors not of Mary, but of Joseph, yet as he was speaking of a matter then generally understood, he deems it enough to show that Joseph was descended from the seed of David, since it is certain that Mary was of the same family. Luke goes still farther, showing that the salvation brought by Christ is common to the whole human race, inasmuch as Christ, the author of salvation, is descended from Adam, the common father of us all. I confess, indeed, that the genealogy proves Christ which Isaac is said to be begotten of Abraham, Joseph of Jacob, Solomon of David, is Christ said to have been begotten of his mother. The Evangelist has arranged his discourse in this way. Wishing to prove that Christ derives his descent from David, he deems it enough to state, that he was begotten of Mary. Hence it follows, that he assumed it as an acknowledged fact, that Mary was of the same lineage as Joseph.
4. The absurdities which they wish to fasten upon us are mere puerile calumnies. They reckon it base and dishonouring to Christ to have derived his descent from men; because, in that case, he could not be exempted from the common law which includes the whole offspring of Adam, without exception, under sin. But this difficulty is easily solved by Paul’s antithesis, “As by one man sin entered into the world, and death by sin”—“even so by the righteousness of one the free gift came upon all men unto justification of life,” (Rom. 5:12, 18). Corresponding to this is another passage, “The first man is of the earth, earthy: the second man is the Lord from heaven,” (1 Cor. 15:47). Accordingly, the same apostle, in another passage, teaching that Christ was sent “in the likeness of sinful flesh, that the righteousness of the law might be fulfilled in us,” distinctly separates him from the common lot, as being true man, and yet without fault and corruption (Rom. 8:3). It is childish trifling to maintain, that if Christ is free from all taint, and was begotten of the seed of Mary, by the secret operation of the Spirit, it is not therefore the seed of the woman that is impure, but only that of the man. We do not hold Christ to be free from all taint, merely because he was born of a woman unconnected with a man, but because he was sanctified by the Spirit, so that the generation was pure and spotless, such as it would have been before Adam’s fall. Let us always bear in mind, that wherever Scripture adverts to the purity of Christ, it refers to his true human nature, since it were superfluous to say that God is pure. Moreover, the sanctification of which John speaks in his seventeenth chapter is inapplicable to the divine nature. This does not suggest the idea of a twofold seed in Adam, although no contamination extended to Christ, the generation of man not being in itself vicious or impure, but an accidental circumstance of the fall. Hence, it is not strange that Christ, by whom our integrity was to be restored, was exempted from the common corruption. Another absurdity which they obtrude upon us—viz. that if the Word of God became incarnate, it must have been enclosed in the narrow tenement of an earthly body, is sheer petulance. For although the boundless essence of the Word was united with human nature into one person, we have no idea of any enclosing. The Son of God descended miraculously from heaven, yet without abandoning heaven; was pleased to be conceived miraculously in the Virgin’s womb, to live on the earth, and hang upon the cross, and yet always filled the world as from the beginning.
