(Hom. lxxi. 1) He speaks now not to Peter alone, but to all: Ye call Me Master and Lord. He accepts their judgment; and to prevent the words being set down merely to favour on their parts, adds, And ye say well, for so I am.
(Hom. lxx. 1) He shows us the greater, that we may do the less. For He was the Lord, but we, if we do it, do it to our fellow-servants: For I have given you an example, that ye should do as I have done to you.
(Hom. lxxi. 2) He continues to urge them to wash one another's feet; Verily, verily, I say unto you, The servant is not greater than his lord, neither He that is sent greater than He that sent Him; as if to say, If I do it, much more ought you.
(Hom. Lxxi. 2) For all know, but all do not do. He then rebukes the traitor, not openly, but covertly: I speak not of you all.
(Hom. lxxi. 1) Then, that He might not sadden them all, He adds, But that the Scripture must be fulfilled, He that eateth bread with Me, hath lifted up his heel against Me: showing that He knew who the traitor was, an intimation that would surely have checked him, if any thing would. He does not say, shall betray Me, but, shall lift up his heel against Me, alluding to his deceit and secret plotting.
(Hom. lxxi. 2) He that eateth bread with Me; i. e. who was fed by Me, who partook of My table. So that if injured ever by our servants or inferiors, we need not be offended. Judas had received infinite benefits, and yet thus requited his Benefactor.
(Hom. Lxxii. 3) As the disciples were about to go forth and to suffer many things, He consoles them by promising His own assistance and that of others; His own, when He says, Happy are ye if ye do them; that of others, in what follows, Verily, verily, I say unto you, He that receiveth whomsoever I send, receiveth Me; and he that receiveth Me receiveth Him that sent Me.
Now when He had washed their feet, and taken His garments, and sat down, He said, "Know ye what I have done unto you?" He no longer addresseth Himself to Peter only, but to them all.
"Ye call Me Lord and Master, and ye say well, for so I am."
"Ye call Me." He taketh to Him their judgment, and then that the words may not be thought to be words of their kindness, He addeth, "for so I am." By introducing a saying of theirs, He maketh it not offensive, and by confirming it Himself when introduced from them, unsuspected. "For so I am," He saith. Seest thou how when He converseth with the disciples, He speaketh revealing more what belongeth unto Himself?
"If I then," He saith, "your Lord and Master have washed your feet, ye ought also to wash one another's feet. For I have given you an example, that ye should do as I have done to you."
And yet it is not the same thing, for He is Lord and Master, but ye are fellow-servants one of another. What meaneth then the "as"? "With the same zeal." For on this account He taketh instances from greater actions that we may, if so be, perform the less. Thus schoolmasters write the letters for children very beautifully, that they may come to imitate them though but in an inferior manner. Where now are they who spit on their fellow-servants? where now they who demand honors? Christ washed the feet of the traitor, the sacrilegious, the thief, and that close to the time of the betrayal, and incurable as he was, made him a partaker of His table; and art thou highminded, and dost thou draw up thine eyebrows?
"Let us then wash one another's feet," saith some one, "then we must wash those of our domestics." And what great thing if we do wash even those of our domestics? In our case "slave" and "free" is a difference of words; but there an actual reality. For by nature He was Lord and we servants, yet even this He refused not at this time to do. But now it is matter for contentment if we do not treat free men as bondmen, as slaves bought with money. And what shall we say in that day, if after receiving proofs of such forbearance, we ourselves do not imitate them at all, but take the contrary part, being in diametrical opposition, lifted up, and not discharging the debt? For God hath made us debtors one to another, having first so done Himself, and hath made us debtors of a less amount. For He was our Lord, but we do it, if we do it at all, to our fellow-servants, a thing which He Himself implied by saying, "If I then your Lord and Master-so also do ye." It would indeed naturally have followed to say, "How much more should ye servants," but He left this to the conscience of the hearers.
But why hath He done this "now"? They were for the future to enjoy, some greater, some less honor. In order then that they may not exalt themselves one above the other, and say as they did before, "Who is the greatest," nor be angry one against the other, He taketh down the high thoughts of them all, by saying, that "although thou mayest be very great, thou oughtest to have no high thoughts towards thy brother." And He mentioned not the greater action, that "if I have washed the feet of the traitor, what great matter if ye one another's?" but having exemplified this by deeds, He then left it to the judgment of the spectators.
"Verily I say unto you, the servant is not greater than his lord, neither he that is sent greater than he that sent him. If ye know these things, happy are ye if ye do them. I speak not of you all - but that the Scripture may be fulfilled, He that eateth bread with Me hath lifted up his heel against Me."
What He said before, this He saith here also, to shame them; "For if the servant is not greater than his master, nor he that is sent greater than him that sent him, and these things have been done by Me, much more ought they to be done by you." Then, lest any one should say, "Why now sayest Thou these things? Do we not already know them?" He addeth this very thing, "I speak not to you as not knowing, but that by your actions ye may show forth the things spoken of." For "to know," belongeth to all; but "to do," not to all. On this account He said, "Blessed are ye if ye do them"; and on this account I continually and ever say the same to you, although ye know it, that I may set you on the work. Since even Jews "know," but yet they are not "blessed"; for they do not what they know.
"I speak not," He saith, "of you all." O what forbearance! Not yet doth He convict the traitor, but veileth the matter, hence giving him room for repentance. He convicteth and yet doth not convict him when He saith thus, "He that eateth bread with Me hath lifted up his heel against Me." It seems to me that the, "The servant is not greater than his lord," was uttered for this purpose also, that if any persons should at any time suffer harm either from domestics or from any of the meaner sort, they should not be offended; looking to the instance of Judas, who having enjoyed ten thousand good things, repaid his Benefactor with the contrary. On this account He added, "He that eateth bread with Me," and letting pass all the rest, He hath put that which was most fitted to restrain and shame him; "he who was fed by Me," He saith, "and who shared My table." And He spake the words, to instruct them to benefit those who did evil to them, even though such persons should continue incurable.
But having said, "I speak not of you all," in order not to attach fear to more than one, He at last separateth the traitor, speaking thus; "He that eateth bread with Me." For the, "not of you all," doth not direct the words to any single one, therefore He added, "He that eateth bread with Me"; showing to that wretched one that He was not seized in ignorance, but even with full knowledge; a thing which of itself was most of all fitted to restrain him. And He said not, "betrayeth Me," but, "hath lifted up his heel against Me," desiring to represent the deceit, the treachery, the secrecy of the plot.
We have just heard in the holy Gospel the Lord speaking, and saying, "Verily, verily, I say unto you, The servant is not greater than his lord, nor the apostle greater than he that sent him: if ye know these things, blessed shall ye be if ye do them." He said this, therefore, because He had washed the disciples' feet, as the Master of humility both by word and example. But we shall be able, with His help, to handle what is in need of more elaborate handling, if we linger not at what is perfectly clear.
If therefore ye understand these things, He saith----that is, "if ye can clearly perceive the meaning of what I am saying,"----blessed are ye if ye do them. For it is not the knowledge of virtue, but rather the practice of it, that may well be pronounced worthy of both love and zeal. And I think that perchance it may be even better never at all to have learned, than after so learning to hamper one's mind with the bonds of indolence, and refuse to carry out in action what one knows to be the best and right course; according to the saying of the Saviour: He that knew not his lord's will, and did it not, shall be beaten with few stripes; but he that knew it, and did it not, shall be beaten with many stripes. For in the case of a man who has sinned in total ignorance, it would not be at all unseemly for him, if perchance he were being visited with correction for his carelessness, to ask for a partial forgiveness: but in the case of one who knew what he was doing, that knowledge would become grievously weighty towards his condemnation. For though nothing was wanting to enable him, yet he disdained to do what was right and seemly. Knowledge therefore must lead to action: for then, clothed with perfect confidence in our citizenship in Christ, we shall receive in due season our most plenteous reward. As an instance of this, the Saviour said that whosoever did and taught [His commandments] should be called great in the kingdom of heaven: and that very justly, for what is wanting to such a man to make his goodness perfect? And whensoever a man can show that he can take to himself full credit for good deeds, then surely he will be able to glory in receiving most perfect gifts from God. And so whenever actions go hand in hand with knowledge, then assuredly there is no trifling gain; but when either is lacking, the other will be very much crippled: and it is written: Even faith apart from works is dead. Although the knowledge of God Who is One even in nature, and the confession of Him in guilelessness and truth is all included in faith, yet even this is dead, if it is not accompanied by the bright light which proceeds from works. Surely therefore it is utterly profitless merely to know what is good and yet to be undesirous to practise it at once. For this reason then He says that His own disciples, and so also all that believe on Him, will be blessed, if they have not only grasped the knowledge of the words spoken by Him, but are also fulfilling those words by their deeds
To know what is good, and not to do it, tendeth not to happiness, but to condemnation; as James saith, To him that knoweth to do good, and doeth it not, to him it is sin (James 4:17). Wherefore He adds, If ye know these things, happy are ye if yo do them.
This was a necessary admonition to the Apostles, some of whom were about to rise higher, others to lower degrees of eminence. That none might exult over another, He changes the hearts of all.
