3 These Jews then saw the man; they neither perceived nor believed Him to be God: and you have already heard how, among all the rest, they said to Him, “You bear witness of yourself; your witness is not true.” You have also heard what He said in reply, as it was read to you yesterday, and according to our ability discussed. Today have been read these words of His, “You judge after the flesh.” Therefore it is, says He, that you say to me, “You bear witness of yourself; your witness is not true,” because you judge after the flesh, because you perceive not God; the man you see, and by persecuting the man, you offend God hidden in Him. “You,” then, “judge after the flesh.” Because I bear witness of myself, I therefore appear to you arrogant. For every man, when he wishes to bear commendatory witness of himself, seems arrogant and proud. Hence it is written, “Let not your own mouth praise you, but let your neighbor's” mouth praise you. But this was said to man. For we are weak, and we speak to the weak. We can speak the truth, but we can also lie; although we are bound to speak the truth, still we have it in our power to lie when we will. But far be it from us to think that the darkness of falsehood could be found in the splendor of the divine light. He spoke as the light, spoke as the truth; but the light was shining in the darkness, and the darkness comprehended it not: therefore they judged after the flesh. “You,” says He, “judge after the flesh.”
4. “I judge not any man.” Does not the Lord Jesus Christ, then, judge any man? Is He not the same of whom we confess that He rose again on the third day, ascended into heaven, there sits at the right hand of the Father, and thence shall come to judge the quick and the dead? Is not this our faith of which the apostle says, “With the heart man believes unto righteousness, and with the mouth confession is made unto salvation?” When, therefore, we confess these things, do we contradict the Lord? We say that He shall come a judge of the quick and the dead, while He says Himself, “I judge not any man.” This question may be solved in two ways: Either that we may understand this expression, “I judge not any man,” to mean, I judge not any man now; in accordance with what He says in another place, “I am not come to judge the world, but to save the world;” not denying His judgment here, but deferring it. Or, otherwise, surely that when He said, “You judge after the flesh,” He subjoined, “I judge not any man,” in such manner that you should understand “after the flesh” to complete the sense. Therefore let no scruple of doubt remain in our heart against the faith which we hold and declare concerning Christ as judge. Christ has come, but first to save, then to judge: to adjudge to punishment those who would not be saved; to bring them to life who, by believing, did not reject salvation. Accordingly, the first dispensation of our Lord Jesus Christ is medicinal, not judicial; for if He had come to judge first, He would have found none on whom He might bestow the rewards of righteousness. Because, therefore, He saw that all were sinners, and that none was exempt from the death of sin, His mercy had first to be craved, and afterwards His judgment must be executed; for of Him the psalm had sung, “Mercy and judgment will I sing to You, O Lord.” Now, He says not “judgment and mercy,” for if judgment had been first, there would be no mercy; but it is mercy first, then judgment. What is the mercy first? The Creator of man deigned to become man; was made what He had made, that the creature He had made might not perish. What can be added to this mercy? And yet He has added thereto. It was not enough for Him to be made man, He added to this that He was rejected of men; it was not enough to be rejected, He was dishonored; it was not enough to be dishonored, He was put to death; but even this was not enough, it was by the death of the cross. For when the apostle was commending to us His obedience even unto death, it was not enough for him to say, “He became obedient unto death;” for it was not unto death of any kind whatever: but he added, “even the death of the cross.” Among all kinds of death, there was nothing worse than that death. In short, that wherein one is racked by the most intense pains is called cruciatus, which takes its name from crux, a cross. For the crucified, hanging on the tree, nailed to the wood, were killed by a slow lingering death. To be crucified was not merely to be put to death; for the victim lived long on the cross, not because longer life was chosen, but because death itself was stretched out that the pain might not be too quickly ended. He willed to die for us, yet it is not enough to say this; He deigned to be crucified, became obedient even to the death of the cross. He who was about to take away all death, chose the lowest and worst kind of death: He slew death by the worst of deaths. To the Jews who understood not, it was indeed the worst of deaths, but it was chosen by the Lord. For He was to have that very cross as His sign; that very cross, a trophy, as it were, over the vanquished devil, He was to put on the brow of believers, so that the apostle said, “God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified to me, and I to the world.” Nothing was then more intolerable in the flesh, nothing is now more glorious on the brow. What does He reserve for His faithful one, when He has put such honor on the instrument of His own torture? Now is the cross no longer used among the Romans in the punishment of criminals, for where the cross of the Lord came to be honored, it was thought that even a guilty man would be honored if he should be crucified. Hence, He who came for this cause judged no man: He suffered also the wicked. He suffered unjust judgment, that He might execute righteous judgment. But it was of His mercy that He endured unjust judgment. In short, He became so low as to come to the cross; yea, laid aside His power, but published His mercy. Wherein did He lay aside His power? In that He would not come down from the cross, though He had the power to rise again from the sepulchre. Wherein did He publish His mercy? In that, when hanging on the cross, He said, “Father, forgive them; for they know not what they do.” Whether, then, it be that He said, “I judge not any man,” because He had come not to judge the world, but to save the world; or, that, as I have mentioned, when He had said, “You judge after the flesh,” He added, “I judge not any man,” for us to understand that Christ judges not after the flesh, like as He was judged by men.
