Haydock's Catholic Bible Commentary: John
Ver. 64. The flesh profiteth nothing. Dead flesh, separated from the spirit, in the gross manner they supposed they were to eat his flesh, would profit nothing. Neither doth man's flesh, that is to say, man's natural and carnal apprehension, (which refuses to be subject to the spirit, and words of Christ) profit any thing. But it would be the height of blasphemy, to say the living flesh of Christ (which we receive in the blessed sacrament, with his spirit, that is, with his soul and divinity) profiteth nothing. For if Christ's flesh had profited us nothing, he would never have taken flesh for us, nor died in the flesh for us. --- Are spirit and life. By proposing to you a heavenly sacrament, in which you shall receive, in a wonderful manner, spirit, grace and life. These words sufficiently correct the gross and carnal imagination of these Capharnaites, that he meant to give them his body and blood to eat in a visible and bloody manner, as flesh, says St. Augustine, is sold in the market, and in the shambles;[3] but they do not imply a figurative or metaphorical presence only. The manner of Christ's presence is spiritual and under the outward appearances of bread and wine; but yet he is there truly and really present, by a change of the substance of bread and wine into the substance of his body and blood, which truly and really become our spiritual food, and are truly and really received in the holy sacrament. --- The flesh[4] of itself profiteth nothing, not even the flesh of our Saviour Christ, were it not united to the divine person of Christ. But we must take care how we understand these words spoken by our Saviour: for it is certain, says St. Augustine, that the word made flesh, is the cause of all our happiness. (Witham) --- When I promise you life if you eat my flesh, I do not wish you to understand this of that gross and carnal manner, of cutting my members in pieces: such ideas are far from my mind: the flesh profiteth nothing. In the Scriptures, the word flesh is often put for the carnal manner of understanding any thing. If you wish to enter into the spirit of my words, raise your hearts to a more elevated and spiritual way of understanding them. (Calmet) --- The reader may consult Des Mahis, p. 165, a convert from Protestantism, and who has proved the Catholic doctrine on the Eucharist in the most satisfactory manner, from the written word. Where he shows that Jesus Christ, speaking of his own body, never says the flesh, but my flesh:
the former mode of expression is used to signify, as we have observed above, a carnal manner of understanding any thing.
Ver. 68. Jesus said to the twelve: Will you also go away? He shews them, says St. Chrysostom, that he stood not in need of them, and so leaves them to their free choice. (Witham) --- Jesus Christ remarking in the previous verse that the apostate disciples had left him, to walk no more with him, turning to the twelve, asks them, Will you also go away? The twelve had heard all that passed; they had seen the Jews strive amongst themselves, and the disciples murmur and leave their Master; they understood what he said in the same literal sense; it could, indeed, bear no other meaning; but when Jesus put the above question to them, leaving them to their free choice, whether to follow him, or to withdraw themselves, Simon Peter answered him: "Lord, to whom shall we go? Thou hast the words of eternal life;" and therefore art able to make good thy words, however hard and difficult they may appear to others. --- We may here admire not only the excellency of their faith, but the plain, yet noble motive of their faith: they believe, because he is Christ, the Son of God, (or, as it is in the Greek, the Son of the living God) who is absolutely incapable of deceiving his creatures, and whose power is perfectly equal to perform the promises he here makes them.
Ver. 69. Simon Peter, the chief or head of them, said in the name of the rest: Lord, to whom shall we go? It is only from thee that we hope for salvation. Thou hast the words of eternal life: we have believed, and known, and remain in this belief, that thou art the Christ, the Son of God. (Witham)
Concluding reflexions on this chapter.
If we take into consideration all the circumstances of this chapter, it will be difficult to conceive how any person can bring their mind to think that there is no connexion between this chapter and the institution of the blessed sacrament. It must proceed, as Dr. Clever, the Protestant Bishop of Bangor, affirms, "from the fear of giving advantage to the doctrine of transubstantiation." He moreover adds: "whilst the institution is considered as a memorial only, nothing can well be further from being plain." See his Sermon on the Lord's Supper. The holy Fathers have unanimously understood these repeated promises of Christ with a reference to the institution. St. Cyprian, of the third age[century], quoting the promises of Christ, the bread which I will give, is my flesh, for the life of the world, deduces this conclusion: "Hence it is manifest, that they have this life, who touch his body, and receive the Eucharist." Qui corpus ejus attingunt. (De Orat. Dom. p. 147.) St. Hilary, of the fourth age[century], quoting Christ's words, says: "there is no place left to doubt of the truth of Christ's flesh and blood, de veritate carnis et sanguinis non relictus est ambigendi locus; for now, by the profession of the Lord himself, and according to our belief, it is truly flesh and truly blood." (De Trin. lib. viii. p. 954-6.) St. Basil, of the fourth century also, citing ver. 53 and 54 of this chapter, says: "about the things that God has spoken there should be no hesitation, nor doubt, but a firm persuasion that all is true and possible, though nature be against it: Kan e phusis machetai. Herein lies the struggle of faith." (Reg. viii. Moral. t. 2, p. 240.) Again the same saint says: "it is very profitable every day, to partake of the body and blood of Christ, phagein to soma kai piein to aima tou kuriou emon, for he that eateth my flesh. &c." (John vi. 55.) "We communicate four times in the week; on Sunday, Wednesday, Friday, and Saturday, and on the other days, if there be a commemoration of any saint." (Ep. xcii. t. 3, p. 186.) --- St. Ambrose, of the same age, says: "the manna in the desert was given in figure. You have known things more excellent. For light is preferable to the shadow; truth to the figure; the body of Christ to the manna of heaven. But you may say: I see somewhat else: how do you assert that I shall receive the body of Christ?" He gives this answer: "How much more powerful is the virtue of the divine blessing, than that of nature; because by the former, nature itself is changed?
... If the blessing of men (he here instances Moses changing a rod into a serpent, and many other miraculous changes) was powerful enough to change nature, what must we not say of the divine consecration, when the very words of the Lord operate? For that sacrament which you receive, is accomplished by the word of Christ. If the word of Elias could call down fire from heaven, shall not the word of Christ be able to change the outward elements? ... The word of Christ could draw out of nothing what was not, shall it not be able to change the things that are into that which they were not? ... Was the order of nature followed when Jesus was born of a Virgin? Certainly not. Then why is that order to be looked for here? It was the true flesh of Christ, which was crucified, which was buried; and this is truly the sacrament of his flesh ... Our Lord himself proclaims, This is my body." --- If Jesus Christ, during his public ministry, performed so many visible and palpable miracles as we read of in the gospels, was it not to induce us to believe without doubting the truths that escape our senses, and surpass our reason? If we believe the water was changed into wine at the marriage feast of Cana; if we believe that the bread in the hands of Christ and his apostles was not diminished, by being broken and divided among five thousand, why cannot we believe the miracle of the Eucharist on the authority of Christ's word, "the bread that I will give you, is my flesh? This is my body," &c. Not one of all the ancient Fathers has ever denied the real presence; not one of them all has ever said, that the body of Jesus Christ is received in figure only.
