John 6:60

"But many of the disciples, when they had heard this, said, This is a hard saying." What means "hard"? Rough, laborious, troublesome. Yet He said nothing of this kind, for He spake not of a mode of life, but of doctrines, continually handling the faith which is in Him. What then means, "is a hard saying"? Is it because it promiseth life and resurrection? Is it because He said that He came down from heaven? Or that it was impossible for one to be saved who ate not His flesh? Tell me, are these things "hard"? Who can assert that they are? What then means "hard"? It means, "difficult to be received," "transcending their infirmity," "having much terror." For they thought that He uttered words too high for His real character, and such as were above Himself. Therefore they said, "Who can hear it?" Perhaps making excuse for themselves, since they were about to start away.

We have just heard out of the Gospel the words of the Lord which follow the former discourse. From these a discourse is due to your ears and minds, and it is not unseasonable to-day; for it is concerning the body of the Lord which He said that He gave to be eaten for eternal life. And He explained the mode of this bestowal and gift of His, in what manner He gave His flesh to eat, saying, "He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him." The proof that a man has eaten and drank is this, if he abides and is abode in, if he dwells and is dwelt in, if he adheres so as not to be deserted. This, then, He has taught us, and admonished us in mystical words that we may be in His body, in His members under Himself as head, eating His flesh, not abandoning our unity with Him. But most of those who were present, by not understanding Him, were offended; for in hearing these things, they thought only of flesh, that which themselves were. But the apostle says, and says what is true, "To be carnally-minded is death." The Lord gives us His flesh to eat, and yet to understand it according to the flesh is death; while yet He says of His flesh, that therein is eternal life. Therefore we ought not to understand the flesh carnally. As in these words that follow: "Many therefore," not of His enemies, but "of His disciples, when they had heard this, said. This is a hard saying; who can hear it?" If His disciples accounted this saying hard, what must His enemies have thought? And yet so it behoved that to be said which should not be understood by all. The secret of God ought to make men eagerly attentive, not hostile. But these men quickly departed from Him, while the Lord said such things: they did not believe Him to be saying something great, and covering some grace by these words; they understood just according to their wishes, and in the manner of men, that Jesus was able, or was determined upon this, namely, to distribute the flesh with which the Word was clothed, piecemeal, as it were, to those that believe on Him. "This," say they, "is a hard saying; who can hear it?"

(Tr. xxvii. 2) Such is our Lord's discourse. The people did not perceive that it had a deep meaning, or, that grace went along with it: but receiving the matter in their own way, and taking His words in a human sense, understood Him as if He spoke of cutting of the flesh of the Word into pieces, for distribution to those who believed on Him: Many therefore, not of His enemies, but even of His disciples, when they heard this, said, This is an hard saying, who can hear it? (Tr. xxvii. 2) And if His disciples thought that saying hard, what would His enemies think? Yet it was necessary to declare a thing, which would be unintelligible to men. God's mysteries should draw men's attention, not enmity.

i. e. that I said, you should eat My flesh, and drink My blood.

When you hear, however, of His disciples murmuring, understand not those really such, but rather some who, as far as their air and behaviour went, seemed to be receiving instruction from Him. For among His disciples were some of the people, who were called such, because they stayed some time with His disciples.
