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).
