Isaias 53:6

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. …

Further, the Lord shows very clearly of Himself, when, describing figuratively His manifold and in many ways serviceable culture, He says, “I am the true vine, and my Father is the husbandman.” Then He adds, “Every branch in me that beareth not fruit He taketh away; and every branch that beareth fruit He pruneth, that it may bring forth more fruit.” For the vine that is not pruned grows to wood. So also man. The Word, the knife, clears away the wanton shoots; compelling the impulses of the soul to fructify, not to indulge in lust. Now, reproof addressed to sinners has their salvation for its aim, the word being harmoniously adjusted to each one’s conduct; now with tightened, now with relaxed cords. …

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. …

And yet it is perhaps better to advance a few testimonies out of the Old Testament also, which ought to have a supplementary, or rather a cumulative value. The Lord Himself, speaking by the Psalmist, says: “As for my saints which are upon earth, He hath caused all my purposes to be admired in them.” Not their merits , but “ my purposes. ” For what is theirs except that which is afterwards mentioned, “their weaknesses are multiplied,”, above the weakness that they had? Moreover, the law also entered, that the offence might abound. But why does the Psalmist immediately add: “They hastened after?” When their sorrows and infirmities multiplied (that is, when their offence abounded), they then sought the Physician more eagerly, in order that, where sin abounded, grace might much more abound. …

7. For it is from prophecy that we convince gainsaying pagans. Who is Christ? says the pagan. To whom we reply, He whom the prophets foretold. What prophets? asks he. We quote Isaiah, Daniel, Jeremiah, and other holy prophets: we tell him that they came long before Christ, by what length of time they preceded His coming. We make this reply then: Prophets came before Him, and they foretold His coming. One of them answers: What prophets? We quote for him those which are daily read to us. And, said he, Who are these prophets? We answer: Those who also foretold the things which we see come to pass. And he urges: You have forged these for yourselves, you have seen them come to pass, and have written them in what books you pleased, as if their coming had been predicted. Here in opposition to pagan enemies the witness of other enemies offers itself. …

2. Now observe I pray how each one of these writers speaks as if concerning things already past, signifying by the use of this tense the absolute inevitable certainty of the event. So also David, describing this tribunal, said, “Why did the heathen rage and the people imagine vain things? The Kings of the earth stood up, and the rulers were gathered together against the Lord and against his Christ.” And not only does he mention the trial, and the cross, and the incidents on the cross, but also him who betrayed him, declaring that he was his familiar companion and guest. …
