John 6:63

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 - 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.

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.
