Valentinus, indeed, on the strength of his heretical system, might consistently fantasize a spiritual flesh for Christ. Any who refused to believe that that flesh was human might then pretend it to be anything he liked. This pretense characterizes all heresies. For if his flesh was not human and was not born of man, I do not see of what substance Paul himself spoke, when he said “The man Christ Jesus is the one mediator between God and man.”
The Apostle Paul likewise says: "The man Christ Jesus is the one Mediator between God and man." Also Peter, in the Acts of the Apostles, speaks of Him as verily human (when he says), "Jesus Christ was a man approved of God among you.
Designated, as He is, "the Mediator between God and man," He keeps in His own self the deposit of the flesh which has been committed to Him by both parties-the pledge and security of its entire perfection.
Wherever it may be, it is in safe keeping in God's presence, through that most faithful "Mediator between God and man, (the man) Jesus Christ," who shall reconcile both God to man, and man to God; the spirit to the flesh, and the flesh to the spirit.
of the flesh; of the Spirit, God-and the angel designated Him as "the Son of God," in respect of that nature, in which He was Spirit, reserving for the flesh the appellation "Son of Man." In like manner, again, the apostle calls Him "the Mediator between God and Men," and so affirmed His participation of both substances.
Now, in order that He might be shown to have together in Himself at once the nature of God and that of man,-as the apostle, too, says: "Mediator between God and men, the man Christ Jesus.
Through his body the church has been allied to Christ and has been enabled to become a partaker in the Word of God. We know this both from the fact that he is called the “mediator of God and humanity,” and from the apostle’s saying that “in him we have access through faith in the hope of the glory of God.”
O how beautiful and mystical and kind! For to intercede does not imply to seek for vengeance, as is most men’s way (for in that there would be something of humiliation), but it is to plead for us by reason of his mediatorship, just as the Spirit is also said to make intercession for us. For “there is one God, and one mediator between God and men, the man Christ Jesus.” For he still pleads even now as man for my salvation. He continues to wear the body which he assumed, until he makes me divine by the power of his incarnation; although he is no longer known after the flesh—the same as ours, except for sin.
By the distinction implied in the word mediator he reveals to us the whole aim of the mystery of godliness. Now the aim is this. Humanity once revolted through the malice of the enemy, and, brought into bondage to sin, was also alienated from the true Life. After this the Lord of the creature calls back to him his own creature and becomes Man while still remaining God, being both God and man in the entirety of the two separate natures. Thus humanity was indissolubly united to God, the man that is in Christ conducting the work of mediation, to whom, by the firstfruits assumed for us, all the lump is potentially united.
But what is he who is at once the Most High and man, what but “the Mediator between God and man, the man Christ Jesus who gave himself as a ransom for us”? This text indeed refers properly to his incarnation, for our redemption was made by his blood, our pardon comes through his power, our life is secured through his grace. He gives as the Most High; he prays as man. The one is the office of the Creator; the other of a redeemer. Be the gifts as distinct as they may, yet the Giver is one, for it was fitting that our Maker should be our Redeemer.
Let not the venom of Apollinaris flatter itself because it is written, “And in appearance he was found as a man,” for the manhood of Jesus is not thereby denied but confirmed, since elsewhere Paul himself speaks of him as “Mediator of God and men, himself man, Christ Jesus.” It is the customary manner of Scripture so to express itself as we also read in the Gospel, “And we saw his glory—glory as of the only-begotten of the Father.” As he is there called only-begotten Son of God, so he is said to be man, and the fullness of humanity that was in him is not denied.
And [know ye, moreover], that He who was born of a woman was the Son of God, and He that was crucified was "the first-born of every creature," and God the Word, who also created all things. For says the apostle, "There is one God, the Father, of whom are all things; and one Lord Jesus Christ, by whom are all things." And again, "For there is one God, and one Mediator between God and man, the man Christ Jesus; " and, "By Him were all things created that are in heaven, and on earth, visible and invisible; and He is before all things, and by Him all things consist."
The Evangelists, too, when they declared that the one Father was "the only true God," did not omit what concerned our Lord, but wrote: "In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by Him, and without Him was not anything made that was made." And concerning the incarnation: "The Word," says [the Scripture], "became flesh, and dwelt among us." And again: "The book of the generation of Jesus Christ, the son of David, the son of Abraham." And those very apostles, who said "that there is one God," said also that "there is one Mediator between God and men." Nor were they ashamed of the incarnation and the passion. For what says [one]? "The man Christ Jesus, who gave Himself" for the life and salvation of the world.
Ver. 5. "For there is one God, and one Mediator between God and men."
He had before said, "to come to the knowledge of the truth," implying that the world is not in the truth. Now he says, "that there is one God," that is, not as some say, many, and that He has sent His Son as Mediator, thus giving proof that He will have all men to be saved. But is not the Son God? Most truly He is; why then does he say, "One God"? In contradistinction to the idols; not to the Son. For he is discoursing about truth and error. Now a mediator ought to have communion with both parties, between whom he is to mediate. For this is the property of a mediator, to be in close communion with each of those whose mediator he is. For he would be no longer a mediator, if he were connected with one but separated from the other. If therefore He partakes not of the nature of the Father, He is not a Mediator, but is separated. For as He is partaker of the nature of men, because He came to men, so is He partaker of the nature of God, because He came from God. Because He was to mediate between two natures, He must approximate to the two natures; for as the place situated between two others is joined to each place, so must that between natures be joined to either nature. As therefore He became Man, so was He also God. A man could not have become a mediator, because he must also plead with God. God could not have been mediator, since those could not receive Him, toward whom He should have mediated. And as elsewhere he says, "There is one God the Father,...and one Lord Jesus Christ" [1 Corinthians 8:6]; so also here "One" God, and "One" Mediator; he does not say two; for he would not have that number wrested to Polytheism, of which he was speaking. So he wrote "One" and "One." You see how accurate are the expressions of Scripture! For though one and one are two, we are not to say this, though reason suggests it. And here you say not one and one are two, and yet you say what reason does not suggest. "If He begot He also suffered." "For there is one God," he says, "and one Mediator between God and men, the Man Christ Jesus."
He says that “there is one God,” that is, not as some say, many, and that he has sent his Son as mediator, thus giving proof that he desires that all be saved. But is not the Son God? Most truly he is. Why then does he say, “One God”? To distinguish the one God from idols, not from the Son.
Christ Jesus, himself man, is the true Mediator, for, inasmuch as he took the “form of a slave,” he became “the Mediator between God and men.” In his character as God, he received sacrifices in union with the Father, with whom he is one God. Yet he chose, in his character as a slave, to be himself the sacrifice rather than to receive it, lest any one might take occasion to think that sacrifice could be rendered to a creature. Thus it is that he is both the Priest who offers and the Oblation that is offered.
But how are we reconciled unless what separates us and him is broken? For he says through the prophet, “The Lord’s ear is not dull, that it cannot hear, but your sins separate you and your God.” Therefore, because we are not reconciled unless what is in the middle has been removed and what should be in the middle has been put there—for there is a separating middle, but over against it is a reconciling mediator. The separating middle is sin. The reconciling mediator is the Lord Jesus Christ, “For there is one God and one mediator of God and man, the man Christ Jesus.” And so, in order that the separating wall which is sin may be taken away, that Mediator has come, and the Priest himself has become the sacrifice.
It was in order to make the mind able to advance more confidently toward the truth that Truth itself, the divine Son of God, put on humanity without putting off his divinity and built this firm path of faith so that man, by means of the God-Man, could find his way to man’s God. I speak of the “mediator between God and men, himself man, Christ Jesus.” For it is as man that he is the Mediator and as man that he is the way.
Hence we respond to this objection of theirs, which they propose from the gospel, in a way which allows no man to be so lacking in understanding that he thinks we are compelled by this text to believe and confess that the mediator between God and men, the man Christ Jesus, did not have a human soul. In the same way I inquire how they respond to objections so palpable as ours, whereby we show through countless places in the Gospel writings what was narrated of him by the Evangelists, namely, that he was found with feelings that are impossible without a soul.
Now, we could not be redeemed, even through “the one mediator between God and man, Man himself, Christ Jesus,” if he were not also God. For when Adam was made—being made an upright man—there was no need for a mediator. Once sin, however, had widely separated the human race from God, it was necessary for a mediator, who alone was born, lived and was put to death without sin, to reconcile us to God and provide even for our bodies a resurrection to life eternal—and all this in order that a man’s pride might be exposed and healed through God’s humility.
Who can so organize what he does as this man organized what he suffered? But the man, the Mediator of God and man, was the man about whom one reads that it was foretold, “And he is a man and who will know him?” For the men through whom these things happened did know the man of God. For he who was hidden as God was apparent as man. He who was apparent suffered these things. He who was hidden is the very same One who ordered these things. Therefore he saw that all the things were finished which were necessary to be done before he took the vinegar and delivered over his spirit.
There is one conciliator of peace, who joins in himself what has been in disjunction. Paul calls Christ man precisely because he is the Mediator, the one in whom human and divine natures are joined in friendship.
May attention to the economy of God which ministered to those of former times be reckoned by you as precious medicine for weak eyes. Let the memory of it stay with you at all times of the day. Meditate, apply your mind, and learn wisdom from it, that you may be able to receive into your soul with honor the memory of the greatness of God and find eternal life for yourself in Christ Jesus, the Mediator between God and mankind and the Uniter in his two natures.
We have heard from the Gospel reading [commenting on Lk 2:1-14], dearly beloved brothers, that when the Redeemer of the world, our Lord and God, Jesus Christ, was about to be born into the world, an edict went out from Caesar Augustus, who then held the highest place with respect to worldly reigns. The edict said that the entire world was to be enrolled. We must not suppose that this happened by chance, but we must understand that it was provided through a most certain divinely arranged plan of this same Redeemer of ours. And, indeed, just as in his divinity the Mediator between God and human beings foresaw the mother of whom he willed to be born when he should so will, so also in his humanity he chose the time when he wished for his nativity. Moreover, he himself granted that this time should be such as he willed, namely, that in a calm among the storm of wars a singular tranquillity of unusual peace should cover the whole world.
