John 6:63

For it is "the Spirit that quickeneth" us for the kingdom of God; "the flesh profiteth nothing." There is, however, something else which can be profitable thereunto, that is, the Spirit; and through the Spirit, the works also of the Spirit.

The words that I have spoken unto you, they are Spirit and are life. He filleth whole His Own Body with the Life-giving operation of the Spirit. For He now calls the Flesh Spirit, not turning It aside from being Flesh: but because by reason of Its being perfectly united to Him, and now endued with His whole Life-giving Power, It ought to be called Spirit too. And no wonder, for be not offended at this. For if he that is joined unto the Lord is one spirit, how shall not His Own Body rather be called One with Him? Something of this kind then He means in the passage before us: I perceive from your reasonings within you (saith He) that ye foolishly imagine that I am telling you, that the body of earth is of its own nature life-giving: but this is not the drift of My words. For My whole exposition to you was of the Divine Spirit and of Eternal Life,. For it is not the nature of the flesh which renders the Spirit life-giving, but the might of the Spirit maketh the Body life-giving. The words then which I have discoursed with you, are spirit, that is spiritual and of the Spirit, and are life, i. e., life-giving and of that which is by Nature Life. And not as repudiating His Own Flesh does He say these things, but as teaching us what is the truth. For what we have just said, this will we repeat for profit sake. The nature of the flesh cannot of itself quicken (for what more is there in Him That is God by Nature?) yet will it not be conceived of in Christ as Alone and by Itself: for it has united to it the Word, Which is by Nature Life. When therefore Christ calls it life-giving, He does not testify the Power of quickening to It so much, as to Himself, or to His Spirit. For because of Him is His Own Body too Life-giving, since He re-elemented It to His Own Power. […]

[In this passage Christ is saying,] "It is not the nature of the flesh that renders the Spirit life-giving but the might of the Spirit that makes the body life-giving. The words then that I have spoken with you are spirit, that, is both spiritual and of the Spirit, and they are life."

Even the body of Christ itself was sanctified by the power of the Word made one with it, and it is thus endowed with living force in the blessed Eucharist so that is it able to implant in us its sanctifying grace.… For here too he says that the flesh can profit nothing, that is, to sanctify and quicken those who receive it, insofar as it is mere human flesh. But when flesh is understood and believed to be the temple of the Word, then surely it will be a channel of sanctification and life, not altogether of itself but through God who has been made one with it, who is holy and life.

It is the Spirit That quickeneth, the flesh profiteth nothing. It is not unreasonably (He says) that ye have clothed the flesh in no power of giving life. For when the nature of the flesh is considered alone and by itself, plainly it is not life-giving. For never will ought of things that are, give life, but rather it hath itself need of Him who is mighty to quicken. But when the Mystery of the Incarnation is carefully considered, and ye then learn who it is who dwelleth in this Flesh, ye will then surely feel (He says) unless you would accuse the Divine Spirit Itself also, that It can impart life, although of itself the flesh profiteth not a whit. For since it was united to the Life-giving Word, it hath become wholly Life-giving, hastening up to the power of the higher Nature, not itself forcing unto its own nature Him who cannot in any wise be subjected. Although then the nature of the flesh be in itself powerless to give life, yet will it inwork this, when it has the Life-working Word, and is replete with His whole operation. For it is the Body of that which is by Nature Life, not of any earthly being, as to whom that might rightly hold, The flesh profiteth nothing. For not the flesh of Paul (for instance) nor yet of Peter, or any other, would work this in us; but only and specially that of our Saviour Christ in whom dwelt all the fulness of the Godhead bodily. For verily it would be a thing most absurd that honey should infuse its own quality into things which naturally have no sweetness, and should have power to transfer into itself that wherewith it is mingled, and that the Life-giving Nature of God the Word should not be able to elevate to Its own good that Body which It indwelt. […]

His meaning is, "Ye must hear spiritually what relateth to Me, for he who heareth carnally is not profited, nor gathereth any advantage." It was carnal to question how He came down from heaven, to deem that He was the son of Joseph, to ask, "How can he give us His flesh to eat?" All this was carnal, when they ought to have understood the matter in a mystical and spiritual sense. "But," saith some one, "how could they understand what the 'eating flesh' might mean?" Then it was their duty to wait for the proper time and enquire, and not to abandon Him. "The words that I speak unto you, they are spirit and they are life." That is, they are divine and spiritual, have nothing carnal about them, are not subject to the laws of physical consequence, but are free from any such necessity, are even set above the laws appointed for this world, and have also another and a different meaning. Now as in this passage He said "spirit," instead of "spiritual," so when He speaketh of "flesh," He meant not "carnal things," but "carnally hearing," and alluding at the same time to them, because they ever desired carnal things when they ought to have desired spiritual. For if a man receives them carnally, he profits nothing. "What then, is not His flesh, flesh?" Most certainly. "How then saith He, that the flesh profiteth nothing?" He speaketh not of His own flesh, (God forbid!) but of those who received His words in a carnal manner. But what is "understanding carnally"? It is looking merely to what is before our eyes, without imagining anything beyond. This is understanding carnally. But we must not judge thus by sight, but must look into all mysteries with the eyes within. This is seeing spiritually. He that eateth not His flesh, and drinketh not His blood, hath no life in him. How then doth "the flesh profit nothing," if without it we cannot live? […]

"It is the Spirit that gives life, the flesh" — that is, carnal understanding — "profits nothing"; Second Corinthians chapter three: "The letter kills, but the spirit gives life"; and therefore the words are not to be understood carnally, because they do not profit that …

Afterwards he showed them a higher degree of love when he said, "It is the Spirit who gives life, the flesh profits nothing." Perhaps this was also true of the Prophet who said: "A Spirit before our face is Christ the Lord." When he adds: …

I do not mean that he who is God is not also man, for the one Christ is both God and man; I mean that all things which are good, even those of which man is the agent, really come from God rather than man. …

Then he settles the offense they took at what he said, concerning the person speaking. The occasion for their scandal was when they heard our Lord say divine things about himself. And so, because they believed that he was the son of Joseph, they were …

They understood Christ's words in a carnal manner, as we have often said, and were scandalized. Therefore He says that only the spiritual understanding of My words is profitable, while the flesh, that is, the carnal understanding of them, is not at all profitable, but …

It is the Spirit - The spiritual meaning of these words, by which God giveth life. The flesh - The bare, carnal, literal meaning, profiteth nothing. The words which I have spoken, they are spirit - Are to be taken in a spiritual sense and, when they are so understood, they are life - That is, a means of spiritual life to the hearers.

It is the Spirit that quickeneth,....

It is the Spirit that quickeneth - These words have been understood in different ways. The word “Spirit,” here, evidently does not refer to the Holy Spirit, for he adds, “The words that I speak unto you, they are spirit.” He refers here, probably, to the doctrine which he had been teaching in opposition to their notions and desires. “My doctrine is spiritual; it is fitted to quicken and nourish the soul. It is from heaven. Your doctrine or your views are earthly, and may be called flesh, or fleshly, as pertaining only to the support of the body.

We learn from these verses that some of Christ's sayings seem hard to flesh and blood. We are told that "many" who had followed our Lord for a season, were offended when He spoke of "eating his flesh and drinking his blood." They murmured and said, "This is an hard saying; who can accept it?" Murmurs and complaints of this kind are very common. It must never surprise us to hear them. They have been, they are, they will be as long as the world stands. To some Christ's sayings appear hard to understand.

OUR Lord had plainly told His hearers that He was the Bread of Life. And that except they ate His flesh and drank His blood there was no life in them. His hearers understood this in a sensual manner and they very naturally put the question, "How can this Man give us His flesh to eat?" Now the Savior had never intended to be understood in a carnal manner. It was far enough from His design to inculcate the carnal eating of His body and therefore He at once told them that His words were not understood.

To a casual reader, it looks as if the meaning of this passage lay upon the very surface, but he who has studied the chapter carefully has discovered that it is a sentence replete with many difficulties as to the exact interpretation of it. I shall not, however, waste your time by entering into any critical discussion of it, but shall only try to give you simply what I believe to be the mind of the Spirit, as uttered by the lips of Jesus in this passage.

We learn from these verses that some of Christ's sayings seem hard to flesh and blood. We are told that "many" who had followed our Lord for a season, were offended when He spoke of "eating his flesh and drinking his blood." They murmured and said, "This is an hard saying; who can accept it?" Murmurs and complaints of this kind are very common. It must never surprise us to hear them. They have been, they are, they will be as long as the world stands. To some Christ's sayings appear hard to understand. To others, as in the present case, they appear hard to believe, and harder still to obey. It is just one of the many ways in which the natural corruption of man shows itself. So long as the heart is naturally proud, worldly, unbelieving, and fond of self-indulgence, if not of sin, so long there will never be lacking people who will say of Christian doctrines and precepts, "These are hard sayings; who can hear them?" Humility is the frame of mind which we should labor and pray for, if we would not be offended by scriptural teaching. If we find any of Christ's sayings hard to understand, we should humbly remember our present ignorance, and believe that we shall know more by and bye. If we find any of His sayings difficult to obey, we should humbly recollect that He will never require of us impossibilities, and that what He bids us do, He will give us grace to perform. We learn, secondly, from these verses, that we must beware of putting a carnal meaning on spiritual words. We read that our Lord said to the murmuring Jews who stumbled at the idea of eating His flesh and drinking His blood, "It is the Spirit who gives life; the flesh profits nothing—the words that I speak unto you, they are spirit and they are life." It is useless to deny that this verse is full of difficulties. It contains expressions "hard to be understood."

OUR Lord had plainly told His hearers that He was the Bread of Life. And that except they ate His flesh and drank His blood there was no life in them. His hearers understood this in a sensual manner and they very naturally put the question, "How can this Man give us His flesh to eat?" Now the Savior had never intended to be understood in a carnal manner. It was far enough from His design to inculcate the carnal eating of His body and therefore He at once told them that His words were not understood. And He delivered Himself of a great general principle, as truly applicable to our day as to His own. In effect He taught them just this—"It is not the eating My flesh in a carnal way, even if you could do it, which would be of any service to you. For that would be only feeding the flesh, which profits nothing. A spiritual feeding can alone quicken and bless you. It is this which you cannot understand. And therefore you hear My words as if they were as dead and fleshly as yourselves, whereas My teaching bears no gross and sensuous meaning, for the words which I speak unto you, they are spirit, and they are life." If I am not mistaken, this verse contains a great principle which needs, in these days, to be proclaimed on the housetops. It is the medicine which would cure the diseases of this present time if men were divinely led to receive it. The text is very deep—like all the teaching of our Savior recorded by John, the words are extremely simple—but the mystery is most profound. May the Holy Spirit lead us all not only to comprehend its teaching, but to feel its power. What is meant by "the flesh" here? The word "flesh" in Scripture has eleven or twelve different modifications of its one abiding meaning. In this passage it means that which is outward and sensuous and appeals to the eye, or the ear, or to other powers of man's bodily nature.

To a casual reader, it looks as if the meaning of this passage lay upon the very surface, but he who has studied the chapter carefully has discovered that it is a sentence replete with many difficulties as to the exact interpretation of it. I shall not, however, waste your time by entering into any critical discussion of it, but shall only try to give you simply what I believe to be the mind of the Spirit, as uttered by the lips of Jesus in this passage. And after I have done that, I shall then revert to what I shall call the meaning which any person would give to it who is not a diligent and careful student of Scripture. That meaning being true, although not the special Truth of God taught in this passage, I shall briefly enlarge upon it. "It is the spirit that quickens; the flesh profits nothing." I suppose there is not a man in the world who could form any intelligent idea of what a spirit is. It is very easy for persons to define a spirit by saying what it is not, but I question whether there is, or ever could be, any man who could form any idea of what it is. We sometimes talk about seeinga spirit—ignorant persons in ages gone by—and some living now in benighted villages talk about seeing spirits by night. They must know that such talk is a contradiction. Matter can be seen, but a spirit, if it clothed itself in any light substance, could not even then be seen—it would only be the substance that would be visible! The spirit itself is a thing which can neither be tasted, handled, seen, nor discerned in any way whatever by our senses, for if it could thus be perceived, there would then be proof positive that it was not a spirit at all, but that it belonged to the material realm. We divide all things into matter and spirit. And whatever can be recognized by the senses in any way, is matter, depend on it.

It is the spirit that quickeneth - It is the spiritual sense only of my words that is to be attended to, and through which life is to be attained, 2Co 3:6. Such only as eat and drink what I have mentioned, in a spiritual sense, are to expect eternal life. The flesh profiteth nothing - If ye could even eat my flesh and drink my blood, this would not avail for your salvation. These words contain a caution that the hearers should not understand his words in the strict literal sense, as if his body were really Bread, and as if his flesh and blood were really to be eaten and drank. The words that I speak - Or, I have spoken. Instead of λαλω, I speak, I read λελαληκα, I have spoken, on the authority of BCDKLT, thirteen others; the Syriac, all the Arabic, all the Persic, Coptic, Ethiopic, Gothic, Slavonic, Vulgate, all the Itala; Origen, Eusebius, Athanasius, Basil, Cyril, Chrysostom, Tertullian, Ambrosias, Augustin, Gaudentius, and Vigilius Taps. This is an important reading, and plainly shows that our Lord’s words here do not refer to any new point of doctrine which he was then inculcating, but to what he had spoken concerning his being the living bread, and concerning the eating of his flesh, and drinking of his blood, in the preceding verses. Are spirit, and they are life - As my words are to be spiritually understood, so the life they promise is of a spiritual nature: see Bishop Pearce.
