Isaias 53:2

But that, having become man for our sakes, He endured to suffer and to be dishonoured, and that He shall come again with glory, hear the prophecies which relate to this; they are these: “Because they delivered His soul unto death, and He was numbered with the transgressors, He has borne the sin of many, and shall make intercession for the transgressors. For, behold, My Servant shall deal prudently, and shall be exalted, and shall be greatly extolled. As many were astonished at Thee, so marred shall Thy form be before men, and so hidden from them Thy glory; so shall many nations wonder, and the kings shall shut their mouths at Him. For they to whom it was not told concerning Him, and they who have not heard, shall understand. O Lord, who hath believed our report? and to whom is the arm of the Lord revealed? We have declared before Him as a child, as a root in a dry ground. …

“Moreover, the prescription that twelve bells be attached to the [robe] of the high priest, which hung down to the feet, was a symbol of the twelve apostles, who depend on the power of Christ, the eternal Priest; and through their voice it is that all the earth has been filled with the glory and grace of God and of His Christ. Wherefore David also says: ‘Their sound has gone forth into all the earth, and their words to the ends of the world.’ And Isaiah speaks as if he were personating the apostles, when they say to Christ that they believe not in their own report, but in the power of Him who sent them. …

2. For this reason [it is, said], “Who shall declare His generation?” since “He is a man, and who shall recognise Him?” But he to whom the Father which is in heaven has revealed Him, knows Him, so that he understands that He who “was not born either by the will of the flesh, or by the will of man,” is the Son of man, this is Christ, the Son of the living God. For I have shown from the Scriptures, that no one of the sons of Adam is as to everything, and absolutely, called God, or named Lord. But that He is Himself in His own right, beyond all men who ever lived, God, and Lord, and King Eternal, and the Incarnate Word, proclaimed by all the prophets, the apostles, and by the Spirit Himself, may be seen by all who have attained to even a small portion of the truth. Now, the Scriptures would not have testified these things of Him, if, like others, He had been a mere man. …

But we must now treat of the garb only and apparatus of office. There is a dress proper to every one, as well for daily use as for office and dignity. That famous purple, therefore, and the gold as an ornament of the neck, were, among the Egyptians and Babylonians, ensigns of dignity, in the same way as bordered, or striped, or palm-embroidered togas, and the golden wreaths of provincial priests, are now; but not on the same terms. For they used only to be conferred, under the name of honour , on such as deserved the familiar friendship of kings (whence, too, such used to be styled the “purpled-men” of kings, just as among us, some, from their white toga, are called “candidates”); but not on the understanding that that garb should be tied to priesthoods also, or to any idol-ceremonies . …

Learn now (over and above the immediate question) the clue to your error. We affirm, two characters of the Christ demonstrated by the prophets, and as many advents of His forenoted: one, in humility (of course the first), when He has to be led “as a sheep for a victim; and, as a lamb voiceless before the shearer, so He opened not His mouth,” not even in His aspect comely. For “we have announced,” says the prophet , “concerning Him, (He is) as a little child, as a root in a thirsty land; and there was not in Him attractiveness or glory. …

It will be your duty, however, to adduce your proofs out of the Scriptures as plainly as we do, when we prove that He made His Word a Son to Himself. For if He calls Him Son, and if the Son is none other than He who has proceeded from the Father Himself, and if the Word has proceeded from the Father Himself, He will then be the Son, and not Himself from whom He proceeded. For the Father Himself did not proceed from Himself. Now, you who say that the Father is the same as the Son, do really make the same Person both to have sent forth from Himself (and at the same time to have gone out from Himself as) that Being which is God. If it was possible for Him to have done this, He at all events did not do it. …

But besides, the prophecies which he introduces into his argument are very different from what the prophets actually foretold of Jesus Christ. For the prophecies do not foretell that God will be crucified, when they say of Him who should suffer, “We beheld Him, and He had no form or comeliness; but His form was dishonoured and marred more than the sons of men; He was a man of sorrows, and acquainted with grief.” Observe, then, how distinctly they say that it was a man who should endure these human sufferings. …

44. For as two advents of our Lord and Saviour are indicated in the Scriptures, the one being His first advent in the flesh, which took place without honour by reason of His being set at nought, as Isaiah spake of Him aforetime, saying, “We saw Him, and He had no form nor comeliness, but His form was despised (and) rejected (lit. = deficient) above all men; a man smitten and familiar with bearing infirmity, (for His face was turned away); He was despised, and esteemed not.” But His second advent is announced as glorious, when He shall come from heaven with the host of angels, and the glory of His Father, as the prophet saith, “Ye shall see the King in glory;” and, “I saw one like the Son of man coming with the clouds of heaven; and he came to the Ancient of days, and he was brought to Him. …

The same rule of truth teaches us to believe, after the Father, also on the Son of God, Christ Jesus, the Lord our God, but the Son of God, of that God who is both one and alone, to wit the Founder of all things, as already has been expressed above. For this Jesus Christ, I will once more say, the Son of this God, we read of as having been promised in the Old Testament, and we observe to be manifested in the New, fulfilling the shadows and figures of all the sacraments, with the presence of the truth embodied. For as well the ancient prophecies as the Gospels testify Him to be the son of Abraham and the son of David. …

Now His humility emboldened them to this deed. For when they read with what great power and glory the Son of God was about to descend from heaven, but on the other hand saw Jesus humble, peaceful, of low condition, without comeliness, they did not believe that He was the Son of God, being ignorant that two advents on His part were foretold by the prophets: the first, obscure in humility of the flesh; the other, manifest in the power of His majesty. Of the first David thus speaks in the seventy-first Psalm: “He shall descend as rain upon a fleece; and in His days shall righteousness spring forth, and abundance of peace, as long as the moon is lifted up.” For as rain, if it descends upon a fleece, cannot be perceived, because it makes no sound; so he said that Christ would come to the earth without exciting the notice of any, that He might teach righteousness and peace. …

“ For the Son of man shall come in the glory of His own Father with His angels. ” Now, indeed, the Son of man has not come in His glory; “for we saw Him, and He had no form nor beauty; but His form was dishonoured and defective compared with the sons of men; He was a man in affliction and toil, and acquainted with the enduring of sickness, because His face was turned away, He was dishonoured and not esteemed.” And it was necessary that He should come in such form that He might bear our sins and suffer pain for us; for it did not become Him in glory to bear our sins and suffer pain for us. …

But if you will understand the differences of the Word which by “the foolishness of preaching” is proclaimed to those who believe, and spoken in wisdom to them that are perfect, you will see in what way the Word has the form of a slave to those who are learning the rudiments, so that they say, “We saw Him and He had no form or beauty.” But to the perfect He comes “in the glory of His own Father,” who might say, “and we beheld His glory, the glory as of the only-begotten from the Father, full of grace and truth.” For indeed to the perfect appears the glory of the Word, and the only-begotten of God His Father, and the fulness of grace and likewise of truth, which that man cannot perceive who requires the “foolishness of the preaching,” in order to believe. …
