John 13:10

"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.

(Tr. lvi. 4) Clean all except the feet. The whole of a man is washed in baptism, not excepting his feet; but living in the world afterwards, we tread upon the earth. Those human affections then, without which we cannot live in this world, are, as it were, our feet, which connect us with human things, so that if we say we have no sin, we deceive ourselves. (1 John 1:8) But if we confess our sins, He who washed the disciples' feet, forgives us our sins even down to our feet, wherewith we hold our converse with earth. (Ad. Seleuc. Ep. c. viii.) From what is here said, we understand that Peter was already baptized. Indeed that He baptized by His disciples, shows that His disciples must have been baptized, either with John's baptism, or, which is more probable, Christ's. He baptized by means of baptized servants; for He did not refuse the ministry of baptizing, Who had the humility to wash feet. (Tr. lvi. 4) Or, the disciples when washed had only to have their feet washed; because while man lives in this world, he contracts himself with earth, by means of his human affections, which are as it were his feet.

"Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit." Some one perhaps may be aroused at this, and say: Nay, but if he is every whit clean, what need has He even to wash his feet? But the Lord knew what He was saying, even though our weakness reach not into His secret purposes. Nevertheless, so far as He is pleased to instruct and teach us out of His law, up to the little measure of my apprehension, I would also, with His help, make some answer bearing on the depths of this question: and, first of all, I shall have no difficulty in showing that there is no self-contradiction in the manner of expression. For who may not say, as here, with the greatest propriety, He is all clean, except his feet?—although he would speak with greater elegance were he to say, He is all clean, save his feet; which is equivalent in meaning. Thus, then, doth the Lord say, "He needeth not save to wash his feet, but is all clean." All, that is, except, or save his feet, which he still needs to wash. But what is this? what does it mean? and what is there in it we need to examine? The Lord says, The Truth declares that even he who has been washed has need still to wash his feet. What, my brethren, what think you of it, save that in holy baptism a man has all of him washed, not all save his feet, but every whit; and yet, while thereafter living in this human state, he cannot fail to tread on the ground with his feet. And thus our human feelings themselves, which are inseparable from our mortal life on earth, are like feet wherewith we are brought into sensible contact with human affairs; and are so in such a way, that if we say we have no sin, we deceive ourselves, and the truth is not in us. And every day, therefore, is He who intercedeth for us, washing our feet: and that we, too, have daily need to be washing our feet, that is, ordering aright the path of our spiritual footsteps, we acknowledge even in the Lord's prayer, when we say, "Forgive us our debts as we also forgive our debtors." For "if," as it is written, "we confess our sins," then verily is He, who washed His disciples' feet, "faithful and just to forgive us our sins, and to cleanse us from all unrighteousness," that is, even to our feet wherewith we walk on the earth.

But the topic on which we were speaking, and which led to our entering on this inquiry, was our Lord's washing His disciples' feet, after the disciples themselves had already been washed, and needed not, save to wash their feet. And we there saw it to be understood that a man is indeed wholly washed in baptism; but while thereafter he liveth in this present world, and with the feet of his human passions treadeth on this earth, that is, in his life-intercourse with others, he contracts enough to call forth the prayer, "Forgive us our debts." And thus from these also is he cleansed by Him who washed His disciples' feet, and ceaseth not to make intercession for us.
