61 When Jesus knew in himself that his disciples murmured at it, he said unto them, Doth this offend you?
[AD 407] John Chrysostom on John 6:60-65
"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.

"When Jesus knew in Himself that His disciples murmured at it," (for this is an attribute of His Godhead to bring secret things to light,) "He said unto them, Doth this offend you? What and if ye shall see the Son of Man ascend up where He was before?"

This also He doth in the case of Nathanael, saying, "Because I said unto thee, I saw thee under the fig-tree, believest thou? Thou shall see greater things than these." And to Nicodemus, "No man hath ascended up to heaven but the Son of man which is in heaven." What then, doth He add difficulties to difficulties? No, (that be far from Him,) but by the greatness of the doctrines, and the number of them, He desireth to bring them over. For if one had said simply, "I have come down from heaven," and added nothing more, he would have been the more likely to offend them; but He who said, "My body is the life of the world"; He who said, "As the living Father hath sent Me, so I live by the Father"; and who said, "I have come down from heaven," solves the difficulty. For the man who utters any one great thing concerning himself may perhaps be suspected of feigning, but he who connects together so many one after another removes all suspicion. All that He doth and saith is intended to lead them away from the thought, that Joseph was His father. And it was not with a wish to strengthen, but rather to do away that stumbling-block, that He said this. For whosoever deemed that He was Joseph's son could not receive His sayings, while one that was persuaded that He had come down from heaven, and would ascend thither, might more easily give heed to His words: at the same time He bringeth forward also another explanation, saying, "It is the Spirit that quickeneth, the flesh profiteth nothing."

His meaning is, "Ye must hear spiritually what relateth to Me, for he who heareth carnally is not profited, nor gathereth any advantage." It was carnal to question how He came down from heaven, to deem that He was the son of Joseph, to ask, "How can he give us His flesh to eat?" All this was carnal, when they ought to have understood the matter in a mystical and spiritual sense. "But," saith some one, "how could they understand what the 'eating flesh' might mean?" Then it was their duty to wait for the proper time and enquire, and not to abandon Him.

"The words that I speak unto you, they are spirit and they are life."

That is, they are divine and spiritual, have nothing carnal about them, are not subject to the laws of physical consequence, but are free from any such necessity, are even set above the laws appointed for this world, and have also another and a different meaning. Now as in this passage He said "spirit," instead of "spiritual," so when He speaketh of "flesh," He meant not "carnal things," but "carnally hearing," and alluding at the same time to them, because they ever desired carnal things when they ought to have desired spiritual. For if a man receives them carnally, he profits nothing. "What then, is not His flesh, flesh?" Most certainly. "How then saith He, that the flesh profiteth nothing?" He speaketh not of His own flesh, (God forbid!) but of those who received His words in a carnal manner. But what is "understanding carnally"? It is looking merely to what is before our eyes, without imagining anything beyond. This is understanding carnally. But we must not judge thus by sight, but must look into all mysteries with the eyes within. This is seeing spiritually. He that eateth not His flesh, and drinketh not His blood, hath no life in him. How then doth "the flesh profit nothing," if without it we cannot live? Seest thou that the words, "the flesh profiteth nothing," are spoken not of His own flesh, but of carnal hearing?

"But there are some of you that believe not."

Again, according to His custom, He addeth weight to His words, by foretelling what would come to pass, and by showing that He spake thus not from desire of honor from them, but because He cared for them. And when He said "some," He excepted the disciples. For at first He said, "Ye have both seen Me, and believe not"; but here, "There are some of you that believe not."

For He "knew from the beginning who they were that believed not, and who should betray Him."

"And He said, Therefore said I unto you, that no man can come unto Me except it were given unto Him from above from My Father."

Here the Evangelist intimates to us the voluntary character of the Dispensation, and His endurance of evil. Nor is the, "from the beginning," put here without a cause, but that thou mayest be aware of His foreknowledge from the first, and that before the words were uttered, and not after the men had murmured nor after they had been offended, He knew the traitor, but before, which was an attribute of Godhead. Then He added, "Except it be given him from above from My Father"; thus persuading them to deem God His Father, not Joseph, and showing them that it is no common thing to believe in Him. As though He had said, "Unbelievers disturb Me not; trouble Me not, astonish Me not. I know of old before they were created, I know to whom the Father hath given to believe"; and do thou, when thou hearest that "He hath given," imagine not merely an arbitrary distribution, but that if any hath rendered himself worthy to receive the gift, he hath received it.

[AD 407] John Chrysostom on John 6:60-65
(Hom. xlvii. 2) i. e. difficult to receive, too much for their weakness. They thought He spoke above Himself, and more loftily than He had a right to do; and so said they, Who can bear it? which was answering in fact for themselves, that they could not.

(Hom. xlvii. 2) The revelation however of these hidden things was a mark of His Divinity: hence the meaning of what follows; And if ye shall see the Son of man ascend up where He was before; supply, What will ye say? He said the same to Nathanael, Because I said to thee, I saw thee under the fig tree, believest thou? Thou shalt see greater things than these. He does not add difficulty to difficulty, but to convince them by the number and greatness of His doctrines. For if He had merely said that He came down from heaven, without adding any thing further, he would have offended His hearers more; but by saying that His flesh is the life of the world, and that as He was sent by the living Father, so He liveth by the Father; and at last by adding that He came down from heaven, He removed all doubt. Nor does He mean to scandalize His disciples, but rather to remove their scandal. For so long as they thought Him the Son of Joseph, they could not receive His doctrines; but if they once believed that He had come down from heaven, and would ascend thither, they would be much more willing and able to admit them.

(Hom. xlvii. 3) He tries to remove their difficulties in another way, as follows, It is the spirit that quickeneth, the flesh profiteth nothing: that is to say, You ought to understand My words in a spiritual sense: he who understands them carnally is profited nothing. To interpret carnally is to take a proposition in its bare literal meaning, and allow no other. But we should not judge of mysteries in this way; but examine them with the inward eye; i. e. understand them spiritually. It was carnal to doubt how our Lord could give His flesh to eat. What then? Is it not real flesh? Yea, verily. In saying then that the flesh profiteth nothing, He does not speak of His own flesh, but that of the carnal hearer of His word.

(Hom. xlvii. 2) i. e. are spiritual, have nothing carnal in them, produce no effects of the natural sort; not being under the dominion of that law of necessity, and order of nature established on earth.

(Hom. xlvii. 2) Having spoken of His words being taken carnally, He adds, But there are some of you that believe not. Some, He says, not including His disciples in the number. This insight shows His high nature.

(Hom. xlvii. 2) To let you know that it was before these words, and not after, that the people murmured and were offended, the Evangelist adds, For Jesus knew from the beginning, who they were that believed not, and who should betray Him.

(Hom. xlvi. 2) As if He said, Men's unbelief does not disturb or astonish Me: I know to whom the Father hath given to come to Me. He mentions the Father, to show first that He had no eye to His own glory; secondly, that God was His Father, and not Joseph.

[AD 430] Augustine of Hippo on John 6:61
"But Jesus, knowing in Himself that His disciples murmured at it,"-for they so said these things with themselves that they might not be heard by Him: but He who knew them in themselves, hearing within Himself,-answered and said, "This offends you;" because I said, I give you my flesh to eat, and my blood to drink, this forsooth offends you.

[AD 430] Augustine of Hippo on John 6:61
(Tr. xxvii. 3) They spoke, however, so as not to be heard by Him. But He, who knew what was in them, heard within Himself: When Jesus knew within Himself that His disciples murmured at it, He said unto them, Doth this offend you?

[AD 1107] Theophylact of Ohrid on John 6:60-61
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.
