John 13:10

He draws His illustration from a common incident of ordinary human life, and opportunely contrives the rebuke to the traitor, teaching the man both to repent of his purpose and to change himself to a better mind. For even if Christ's reproaches do not yet convict him of his meditated treachery, yet the saying must carry with it a stern significance. For in testifying to the perfect cleanness of some [but not all] of the disciples, He thereby makes the one who was not clean feel an uneasy suspicion, and points out the presence of a polluted one. For Christ graciously commends the cleanness of His other disciples, as shown by their willing joy in attending on Him continually, the hardship they underwent in following Him, their firmness in faith, and their fulness of love towards Him. On Judas, however, the reproach of his insatiable covetousness and the feebleness of his affection for our Lord Jesus the Christ are branding the ineffaceable stain, and steeping him in the pollution, of his incomparably hideous treachery. When therefore Christ says: Now ye are clean, but not all, though the language is obscure, yet it conveys a profitable rebuke to the traitor. For although He did not speak plainly, as we have just said, still in each man's heart conscience was sitting in judgment, pricking the sinner to the heart, and bringing home to the guilty one the force of the words according to their necessary meaning. And notice how fully the conduct of Christ is expressive of a certain set purpose and of God-befitting forbearance. For if He had said plainly who it was that would betray Him, He would have made the other disciples to be at enmity with the traitor. […]

"He that is washed, needeth not save to wash his feet, but is clean every whit; and ye are clean, but not all. For He knew who should betray Him." "And if they are clean, why washeth He their feet?" That we may learn to be modest. On which account He came not to any other part of the body, but to that which is considered more dishonorable than the rest. But what is, "He that is washed"? It is instead of, "he that is clean." Were they then clean, who had not yet been delivered from their sins, nor deemed worthy of the Spirit, since sin still had the mastery, the handwriting of the curse still remaining, the victim not having yet been offered? How then calleth He them "clean"? That thou mayest not deem them clean, as delivered from their sins, He addeth, Behold, "ye are clean through the word that I have spoken unto you." That is, "In this way ye are so far clean; ye have received the light, ye have been freed from Jewish error. For the Prophet also saith, 'Wash you, make you clean, put away the wickedness from your souls'; so that such a one is washed and is clean." Since then these men had cast away all wickedness from their souls, and had companied with Him with a pure mind, therefore He saith according to the word of the Prophet, "he that is washed is clean already." For in that place also It meaneth not the "washing" of water, practiced by the Jews; but the cleansing of the conscience.

Simon did not want his teacher to wash his feet. The purpose of our Lord's action was … to teach you that you should deeply love and eagerly help one another. Peter did not know that that was the purpose of his action. So again …

Many ask: why did the Lord say to the apostles "you are clean," when they had not yet been freed from sins, had not received the Spirit, since sin still reigned, the curse still retained its force, for the Lamb who takes away the sin …

Jesus says to him: He who has been washed, namely with that washing of which it is said in Isaiah 1: "Wash yourselves, be clean"; and Zechariah 13: "There shall be a fountain open to the house of David and to the inhabitants of Jerusalem …

Jesus is giving clear notice that this washing of the feet indicates pardoning of sins, and not only that which is given once in baptism but in addition that by which the daily guilty actions of the faithful that everyone lives with in this life …

Then (v 10), the Evangelist gives our Lord's answer. First, our Lord states a general principle; secondly, he applies it to this situation; and thirdly, the Evangelist explains these words of Christ. He says at first, he who has bathed does not need to wash, …

He washed them himself, and then said, You are clean; but he excepts Judas: not all; they were all baptized, even Judas, yet not all clean; many have the sign that have not the thing signified. Note, [1.] Even among those who are called disciples of Christ, and profess relation to him, there are some who are not clean, Prov. xxx.

Jesus saith to him, he that is washed,....

Peter had gone from one extreme to the other. At first he would not let Christ wash his feet; and now he overlooks what Christ had done for him in his baptism, and what was signified thereby, and cries out to have his hands and head washed.

He that is washed - That is, he who has been in the bath, as probably all the apostles had lately been, in order to prepare themselves the better for the paschal solemnity; for on that occasion, it was the custom of the Jews to bathe twice. Needeth not save to wash his feet - To cleanse them from any dirt or dust that might have adhered to them, in consequence of walking from the bath to the place of supper.

This sentence is singularly instructive. Of the two cleansings, the one points to that which takes place at the commencement of the Christian life, embracing complete absolution from sin as a guilty state, and entire deliverance from it as a polluted life (Re 1:5; 1Co 6:11) --or, in the language of theology, Justification and Regeneration.

Lord, dost thou wash my feet?--Our language cannot bring out the intensely vivid contrast between the "Thou" and the "my," which, by bringing them together, the original expresses, for it is not good English to say, "Lord, Thou my feet dost wash?" But every word of this question is emphatic.

The verses we have now read conclude the story of our Lord's washing the feet of His disciples, the night before He was crucified. It is a story full of touching interest, which for some wise reason no Evangelist records except John. The wonderful condescension of Christ, in doing such a menial action, can hardly fail to strike any reader. The mere fact that the Master should wash the feet of the servants might well fill us with surprise. But the circumstances and sayings which arose out of the action are just as interesting as the action itself.

The verses we have now read conclude the story of our Lord's washing the feet of His disciples, the night before He was crucified. It is a story full of touching interest, which for some wise reason no Evangelist records except John. The wonderful condescension of Christ, in doing such a menial action, can hardly fail to strike any reader. The mere fact that the Master should wash the feet of the servants might well fill us with surprise. But the circumstances and sayings which arose out of the action are just as interesting as the action itself. Let us see what they were. We should notice, firstly, the hasty ignorance of the Apostle Peter. One moment we find him refusing to allow his Master to do such a servile work as He is about to do—"Do you wash my feet?" "You shall never wash my feet." Another moment we find him rushing with characteristic impetuosity into the other extreme—"Lord, wash not my feet only, but my hands and my head." But throughout the transaction we find him unable to take in the real meaning of what his eyes behold. He sees, but he does not understand. Let us learn from Peter's conduct that a man may have plenty of faith and love, and yet be sadly destitute of clear knowledge. We must not set down men as graceless and godless because they are dull, and stupid, and blundering in their religion. The heart may often be quite right when the head is quite wrong. We must make allowances for the corruption of the understanding, as well as of the will. We must not be surprised to find that the brains as well as the affections of Adam's children have been hurt by the fall. It is a humbling lesson, and one seldom fully learned except by long experience.

He that is washed - This is a difficult passage, and interpreters have been divided about its meaning. Some have supposed that it was customary to bathe before eating the paschal supper, and that the apostles did it; Jesus having said, “he that hath bathed his body is clean except in regard to his feet - to the dirt contracted in returning from the bath, and that there was need only that the feet should be washed in order to prepare them properly to receive the supper.” They suppose, also, that the lesson which Jesus meant to teach was that they were really pure Joh 15:3; that they were qualified to partake of the ordinances of religion, and needed only to be purified from occasional blemishes and impurities (Grotius). Others say that there is not evidence that the Jews bathed before partaking of the Paschal Supper, but that reference is made to the custom of washing their hands and their face. It is known that this was practiced. See the Mat 15:2 note; Mar 7:3-4 notes. Peter had requested him to wash his hands and his head. Jesus told him that as that had been done, it was unnecessary to repeat it; but to wash the feet was an act of hospitality, the office of a servant, and that all that was needed now was for him to show this condescension and humility. Probably reference is had here to internal purity, as Jesus was fond of drawing illustrations from every quarter to teach them spiritual doctrine; as if he had said, “You are clean by my word and ministry Joh 15:3; you are my followers, and are prepared for the scene before you. But one thing remains. […]
