Isaias 53:1

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. …

“For the Holy Spirit sometimes brought about that something, which was the type of the future, should be done clearly; sometimes He uttered words about what was to take place, as if it was then taking place, or had taken place. And unless those who read perceive this art, they will not be able to follow the words of the prophets as they ought. For example’s sake, I shall repeat some prophetic passages, that you may understand what I say. When He speaks by Isaiah, ‘He was led as a sheep to the slaughter, and like a lamb before the shearer,’ He speaks as if the suffering had already taken place. And when He says again, ‘I have stretched out my hands to a disobedient and gainsaying people;’ and when He says, ‘Lord, who hath believed our report?’, the words are spoken as if announcing events which had already come to pass. …

“So that you ought rather to desist from the love of strife, and repent before the great day of judgment come, wherein all those of your tribes who have pierced this Christ shall mourn, as I have shown has been declared by the Scriptures. And I have explained that the Lord swore, ‘after the order of Melchizedek,’ and what this prediction means; and the prophecy of Isaiah which says, ‘His burial is taken away from the midst,’ I have already said, referred to the future burying and rising again of Christ; and I have frequently remarked that this very Christ is the Judge of all the living and the dead. …

“Lord, who hath believed our report?” Isaiah says. For “faith cometh by hearing, and hearing by the word of God,” saith the apostle. “How then shall they call on Him in whom they have not believed? And how shall they believe on Him whom they have not heard? And how shall they hear without a preacher? And how shall they preach except they be sent? As it is written, How beautiful are the feet of those that publish glad tidings of good things.” You see how he brings faith by hearing, and the preaching of the apostles, up to the word of the Lord, and to the Son of God. We do not yet understand the word of the Lord to be demonstration.

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. …

Well then, you reply, if He was God who spoke, and He was also God who created, at this rate, one God spoke and another created; (and thus) two Gods are declared. If you are so venturesome and harsh, reflect a while; and that you may think the better and more deliberately, listen to the psalm in which Two are described as God: “Thy throne, O God, is for ever and ever; the sceptre of Thy kingdom is a sceptre of righteousness . Thou hast loved righteousness, and hated iniquity: therefore God, even Thy God, hath anointed Thee or made Thee His Christ .” Now, since He here speaks to God, and affirms that God is anointed by God, He must have affirmed that Two are God, by reason of the sceptre’s royal power. …

17. These testimonies are sufficient for the believing who study truth, and the unbelieving credit no testimony. For the Holy Spirit, indeed, in the person of the apostles, has testified to this, saying, “And who has believed our report?” Therefore let us not prove ourselves unbelieving, lest the word spoken be fulfilled in us. Let us believe then, dear brethren, according to the tradition of the apostles, that God the Word came down from heaven, (and entered) into the holy Virgin Mary, in order that, taking the flesh from her, and assuming also a human, by which I mean a rational soul, and becoming thus all that man is with the exception of sin, He might save fallen man, and confer immortality on men who believe on His name. …

In Isaiah: “Is God’s Hand not strong to save? or has He made His ear heavy, that He cannot hear? But your sins separate between you and God; and on account of your sins He turns His face away from you, that He may not pity. For your hands are defiled with blood, and your fingers with sins. Moreover, your lips have spoken wickedness, and your tongue meditates unrighteousness. No one speaketh truth, nor is there true judgment: they trust in vanity, and speak emptiness, who conceive sorrow, and bring forth wickedness.” Also in the same place: “Lord, who hath believed our report? and to whom is the Arm of God revealed?” Also in the same: “Thus saith the Lord, Heaven is my throne, and the earth is the support of my feet. …

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. …

XVI . See how the people provoked the Lord by not believing in Him! Therefore He says: “They provoked the Holy Spirit, and He was turned to be their enemy.” For blindness is cast upon them, by reason of the wickedness of their mind, because when they saw Jesus they did not believe Him to be the Christ of God, who was before all ages begotten of Him, His only-begotten Son, God the Word, whom they did not own through their unbelief, neither on account of His mighty works, nor yet on account of the prophecies which were written concerning Him. …

Will any man dare to say that God did not foreknow those to whom He would give to believe, or whom He would give to His Son, that of them He should lose none? And certainly, if He foreknew these things, He as certainly foreknew His own kindnesses, wherewith He condescends to deliver us. This is the predestination of the saints, nothing else; to wit, the foreknowledge and the preparation of God’s kindnesses, whereby they are most certainly delivered, whoever they are that are delivered. But where are the rest left by the righteous divine judgment except in the mass of ruin, where the Tyrians and the Sidonians were left? who, moreover, might have believed if they had seen Christ’s wonderful miracles. But since it was not given to them to believe, the means of believing also were denied them. …
