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. You place a great value on the doctrine that Moses fed the body; yet that did not permanently profit, for your fathers are dead. You seek also food from me, but your views and desires are gross and earthly."

Quickeneth - Gives life. See the notes at John 5:21.

The flesh - Your carnal views and desires, and the literal understanding of my doctrine. By this Jesus shows them that he did not intend that his words should be taken literally.

Profiteth nothing - Would not avail to the real needs of man. The bread that Moses gave, the food which you seek, would not be of real value to man's highest wants.

They are spirit - They are spiritual. They are not to be understood literally, as if you were really to eat my flesh, but they are to be understood as denoting the need of that provision for the soul which God has made by my coming into the world.

Are life - Are fitted to produce or give life to the soul dead in sins.

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, 2 Corinthians 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.

It is the Spirit that quickeneth,.... It is the spirit of man that quickens him; or which being breathed into him, he becomes a living soul; for the body, without the spirit, is dead; it is a lifeless lump: and it is the Spirit of God that quickens dead sinners, by entering into them as the spirit of life, and causing them to live: and it is spiritual eating, or eating the flesh, and drinking the blood of Christ in a spiritual sense, which quickens, refreshes, and comforts the minds of believers; it is that by, and on which they live, and by which their spiritual strength is renewed: unless, by spirit, is meant the divine nature of Christ, by which he was quickened and raised from the dead, and ascended up into heaven, and was declared to be the Son of God with power:

the flesh profiteth nothing; the human nature of Christ, though profitable, as in union with the Son of God, to be given for the life of his people, and to be an offering, and a sacrifice for their sins, yet not as alone, or as abstracted from the divine nature; nor would his flesh and blood, corporeally eaten, could, or should it be done, be of any avail to eternal life; nor is any other flesh, literally understood, profitable of itself for life; for man lives not by bread, or meat, or flesh alone, but by the word and blessing of God upon it, and along with it; nor flesh, in a figurative sense, as creature acts and performances, self-righteousness, obedience to the ceremonial law, carnal descent, and birth privileges:

the words that I speak unto you, they are spirit, and they are life; the doctrines which Christ had then been delivering concerning himself, his flesh and blood, being spiritually understood, are the means of quickening souls. The Gospel, and the truths of it, which are the wholesome words of our Lord Jesus Christ, are the means of conveying the Spirit of God, as a spirit of illumination and sanctification, into the hearts of men, and of quickening sinners dead in trespasses and sins: the Gospel is the Spirit that giveth life, and is the savour of life unto life, when it comes not in word only, or in the bare ministry of it, but with the energy of the Holy Ghost, and the power of divine grace.

{14} It is the {x} spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.

(14) The flesh of Christ therefore quickens us, because he that is man is God: and this mystery is only comprehended by faith, which is the gift of God, found only in the elect.

(x) Spirit, that is, that power which flows from the Godhead causes the flesh of Christ (which is otherwise nothing but flesh) both to live in itself and to give life to us.

6:63 It is the spirit that quickeneth. We may paraphrase this verse thus: I shall ascend to heaven so that my body cannot be literally eaten; the flesh literally profits nothing. It is the spirit that makes alive. The spirits of men must feed upon me by faith, that they may be made alive. My words are spirit and life. He who feeds upon them will be made alive.

6:63 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.

63. the flesh profiteth nothing-Much of His discourse was about "flesh"; but flesh as such, mere flesh, could profit nothing, much less impart that life which the Holy Spirit alone communicates to the soul.

the words that I speak . are spirit and . life-The whole burden of the discourse is "spirit," not mere flesh, and "life" in its highest, not its lowest sense, and the words I have employed are to be interpreted solely in that sense.

6:60-65 The human nature of Christ had not before been in heaven, but being God and man, that wondrous Person was truly said to have come down from heaven. The Messiah's kingdom was not of this world; and they were to understand by faith, what he had said of a spiritual living upon him, and his fulness. As without the soul of man the flesh is of no value, so without the quickening Spirit of God all forms of religion are dead and worthless. He who made this provision for our souls, alone can teach us these things, and draw us unto Christ, that we may live by faith in him. Let us apply to Christ, thankful that it is declared that every one who is willing to come unto him shall be made welcome.
