John 6:52 - Joseph Benson’s Commentary on the Old and New Testaments

The Jews therefore strove among themselves Greek, εμαχοντο, literally, they fought, that is, they debated with great violence, some being inclined to believe, others to reject this doctrine; some, doubtless, taking his words in one sense, others in another, and some vindicating, and others deriding and censuring them, and, as if what he had advanced was to be taken in a literal sense, the generality saying, How can this man give us his flesh to eat? What a monstrous and unintelligible doctrine is this! Observe, reader, the effects of this discourse of Christ: the Jews are tried here; the disciples, John 6:60; John 6:66; the apostles, John 6:67. Then Jesus Proceeding in the same figurative language he had used before, and without condescending to make any further explication; said unto them, Verily, Except ye eat the flesh of the Son of man, &c., ye have no life in you As if he had said, However you may censure my doctrine as unintelligible and absurd, yet nothing can be more certain than it, or more important to you. For except you be entirely united to me by a firm and lively faith in the truth and importance of my doctrine, and a cordial dependance, for acceptance with God, on the merit of the sacrifice which I shall offer for the sins of the world, thereby deriving spiritual strength and nourishment from me, through the influences of my Spirit, in the use of those means of grace which I shall institute, you can have no spiritual life in you here, nor attain eternal life hereafter. The reader will easily observe, that by eating his flesh and drinking his blood, our Lord did not mean any corporeal action whatever, but men's receiving in faith, and with gratitude, those blessings, to confer which he assumed the human nature. The expression therefore implies a true and lively faith in “the revelation he came to make, concerning the merciful counsels of God for the salvation of sinners; or, as he himself expresses it, John 6:63, The word that he spake to them, especially concerning his incarnation, and his dying to make atonement for sin. Which articles of the Christian faith, being particularly understood here, give propriety to the metaphors of eating Christ's flesh and drinking his blood, by which the whole of that faith is denominated. The reason is, of all the discoveries made by Christ, those concerning his incarnation, and the nature and ends of his death, received and meditated upon with a lively faith, afford sovereign and salutary nourishment unto the minds of sinners. They are as effectual for sustaining the spiritual life in the soul, as flesh, fitly prepared, is for nourishing the animal life in the body.” The sacrament of the eucharist was plainly intended to affect our minds with a sense of these important truths, and our Lord might probably think of that intended institution while he spoke: but as this was a future thing, and utterly unknown to his hearers, it would be very unwarrantable to interpret this text as chiefly referring to that ordinance.
