63. It is the Spirit that quickeneth. By these words Christ shows the reason why the Jews did not profit by his doctrine to be, that, being spiritual and quickening, it does not find ears well prepared. But as this passage has been variously expounded, it will be of importance first to ascertain the natural meaning of the words; from which it will be easy to perceive Christ’s intention. When he affirms that the flesh profiteth nothing, Chrysostom improperly, in my opinion, refers it to the Jews, who were carnal I readily acknowledge that in heavenly mysteries the whole power of the human mind is utterly unavailing; but the words of Christ do not bear that meaning, if they be not violently tortured. Equally forced would be that opinion, as applied to the apposite clause; namely, it is the illumination of the Spirit that quickeneth. Nor do I approve of the views of those who say, that the flesh of Christ profiteth, so far as he was crucified, but that, when it is eaten, it is of no advantage to us; for, on the contrary, we must eat it, that, having been crucified, it may profit

Augustine thinks that we ought to supply the word only, or by itself, as if it had been said, “The flesh alone, and by itself, profiteth not,” ¹⁷³¹⁷³     “Comme s’il estoit dit, La chair seule et par soy ne profite de rien.” because it must be accompanied by the Spirit This meaning accords well with the scope of the discourse, for Christ refers simply to the manner of eating. He does not, therefore, exclude every kind of usefulness, as if none could be obtained from his flesh; but he declares that, if it be separated from the Spirit, it will then be useless. For whence has the flesh power to quicken, but because it is spiritual? Accordingly, whoever confines his whole attention to the earthly nature of the flesh, will find in it nothing but what is dead; but they who shall raise their eyes to the power of the Spirit, which is diffused over the flesh, will learn from the actual effect and from the experience of faith, that it is not without reason that it is called quickening

We now understand in what manner the flesh is truly food, and yet it profiteth not It is food, because by it life is procured for us, because in it God is reconciled to us, because in it we have all the parts of salvation accomplished. It profiteth not, if it be estimated by its origin and nature; for the seed of Abraham, which is in itself subject to death, does not bestow life, but receives from the Spirit its power to feed us; and, therefore, on our part also, that we may be truly nourished by it, we must bring the spiritual mouth of faith.

As to the sentence breaking off in so abrupt a manner, it is probable that this was done because Christ saw that it was necessary to act in this manner towards unbelievers. By this clause, therefore, he suddenly closed the sermon, because they did not deserve that he should speak to them any longer. Yet he did not overlook those who are godly and teachable; for they have here, in a few words, what may abundantly satisfy them.

The words which I speak to you. This is an allusion to the preceding statement, for he now employs the word Spirit in a different sense. But as he had spoken of the secret power of the Spirit, he elegantly applies this to his doctrine, because it is spiritual; for the word Spirit must be explained to mean spiritual Now the word is called spiritual, because it calls us upwards to seek Christ in his heavenly glory, through the guidance of the Spirit, by faith, and not by our carnal perception; for we know that of all that was said, nothing can be comprehended but by faith. And it is also worthy of observation, that he connects life with the Spirit He calls his word life, from its effect, as if he had called it quickening; but shows that it will not be quickening to any but those who receive it spiritually, for others will rather draw death from it. To the godly, this commendation bestowed on the Gospel is most delightful, because they are certain that it is appointed for their eternal salvation; but at the same time, they are reminded to labor to prove that they are genuine disciples.

64. But there are some of you who do not believe. He again imputes blame to them, because, being destitute of the Spirit, they wickedly corrupt and debase his doctrine, and thus turn it to their ruin. For otherwise they might have objected: “You boast, indeed, that what you speak is quickening, but we experience nothing of that nature.” He therefore says, that by themselves it is prevented; for unbelief, as it is always proud, will never understand any thing in the words of Christ which it despises and disdains. Wherefore, if we wish to profit at all under this Teacher, let us bring minds well disposed to listen to him; for if the entrance to his doctrine be not opened up by humility and reverence, our understandings are harder than stones, and will not receive any part of sound doctrine. And therefore, when in the present day we see so few people in the world profiting by the Gospel, we ought to remember that this arises from the depravity of men. For how many will you find who deny themselves, and truly submit to Christ? As to his saying only that there were some who did not believe, though almost all of them were liable to this charge, his reason for doing so appears to have been that, if there were any who were not yet beyond the possibility of cure, they might not cast down their minds in despair.

For Jesus knew from the beginning. The Evangelist added this, that none might think that Christ formed an opinion at random about his hearers. Many professed to belong to his flock, but a sudden apostacy exposed their hypocrisy. But the Evangelist says that their treachery, even while it was unknown to others, was well known to Christ. And this is stated, not so much on his account, as that we may learn not to form a judgment except on subjects which we have thoroughly investigated; for as to their being known to Christ from the beginning, this was peculiar to his Divinity. It is otherwise with us; for since we do not know the hearts, we ought to delay forming a judgment, until impiety be manifested by outward signs, and thus the tree be known by its fruits, (Matthew 7:16.)

65. Therefore have I told you. He again states that faith is an uncommon and remarkable gift of the Spirit of God, that we may not be astonished that the Gospel is not received in every place and by all. For, being ill qualified to turn to our advantage the course of events, we think more meanly of the Gospel, because the whole world does not assent to it. The thought arises in our mind, How is it possible that the greater part of men shall deliberately reject their salvation? Christ therefore assigns a reason why there are so few believers, namely, because no man, whatever may be his acuteness, ¹⁷⁴¹⁷⁴     “Tant aigu soit il.” can arrive at faith by his own sagacity; for all are blind, until they are illuminated by the Spirit of God, and therefore they only partake of so great a blessing whom the Father deigns to make partakers of it. If this grace were bestowed on all without exception, it would have been unseasonable and inappropriate to have mentioned it in this passage; for we must understand that it was Christ’s design to show that not many believe the Gospel, because faith proceeds only from the secret revelation of the Spirit.

Unless it be given him by my Father. He now uses the word give instead of the word which he formerly used, draw; by which he means that there is no other reason why God draws, than because out of free grace he loves us; for what we obtain by the gift and grace of God, no man procures for himself by his own industry.

66. From that time many of his disciples went back. The Evangelist now relates what trouble was the consequence of that sermon. It is a dreadful and monstrous thing, that so kind and gracious an invitation of Christ could have alienated the minds of many, and especially of those who had formerly professed to belong to him, and were even his ordinary disciples. But this example is held out to us for a mirror, as it were, in which we may perceive how great is the wickedness and ingratitude of men, who turn a plain road into an occasion of stumbling to them, that they may not come to Christ. Many would say that it would have been better that a sermon of this kind should never have been preached, which occasioned the apostacy of many. But we ought to entertain a widely different view; for it was then necessary, and now is daily necessary, that what had been foretold concerning Christ should be perceived in his doctrine, namely, that

he is the stone of stumbling, (Isaiah 8:14.)

We ought, indeed, to regulate our doctrine in such a manner that none may be offended through our fault; as far as possible, we ought to retain all; and, in short, we ought to take care that we do not, by talking inconsiderately or at random, ¹⁷⁵¹⁷⁵     “Inconsiderement, ou a la volee.” disturb ignorant or weak minds. But it will never be possible for us to exercise such caution that the doctrine of Christ shall not be the occasion of offense to many; because the reprobate, who are devoted to destruction, suck venom from the most wholesome food, and gall from honey. The Son of God undoubtedly knew well what was useful, and yet we see that he cannot avoid ¹⁷⁶¹⁷⁶     “Il ne peut eviter.” offending many of his disciples. Whatever then may be the dislike entertained by many persons for pure doctrine, still we are not at liberty to suppress it. Only let the teachers of the Church remember the advice given by Paul, that the word of God ought to be properly divided, (2 Timothy 2:15;) and next let them advance boldly amidst all offenses. And if it happen that many apostatize, let us not be disgusted at the word of God, because it is not relished by the reprobate; for they who are so much shaken by the revolt of some that, when those persons fall away, they are immediately discouraged, are too delicate and tender.

And walked no more with him. When the Evangelist adds these words, he means that it was not a complete apostacy, but only that they withdrew from familiar intercourse with Christ; and yet he condemns them as apostates. Hence we ought to learn that we cannot go back a foot breadth, without being immediately in danger of falling into treacherous denial of our Master.

67. Jesus therefore said to the twelve. As the faith of the apostles might be greatly shaken, when they saw that they were so small a remnant of a great multitude, Christ directs his discourse to them, and shows that there is no reason why they should allow themselves to be hurried away by the lightness and unsteadiness of others. When he asks them if they also wish to go away, he does so in order to confirm their faith; for, by exhibiting to them himself, that they may remain with him, he likewise exhorts them not to become the companions of apostates. And, indeed, if faith be founded on Christ, it will not depend on men, and will never waver, though it should see heaven and earth mingling. We ought also to observe this circumstance, that Christ, when deprived of nearly all his disciples, retains the twelve only, in like manner as Isaiah was formerly commanded to

bind the testimony and seal the law among the disciples,
(Isaiah 8:16.)

By such examples, every one of the believers is taught to follow God, even though he should have no companion.

68. Simon Peter therefore answered him. Peter replies here in the name of all, as he does on other occasions; because all of them were of the same mind, except that in Judas there was no sincerity. This reply contains two clauses; for Peter first states the reason why he cheerfully adheres to Christ, along with his brethren; namely, because they feel that his doctrine is wholesome and quickening; and, secondly, he acknowledges that to whomsoever they might go, if they left Christ, there remained for them nothing but death.

Thou hast the words of eternal life. When he says the words of life, by the phrase of life, he means quickening, using the genitive case instead of the adjective, which is a very common mode of expression among the Hebrews. It is a remarkable commendation bestowed on the Gospel, that it administers to us eternal life, as Paul testifies, that

it is the power of God for salvation to every one who believeth,
(Romans 1:16.)

True, the Law also contains life, but because it denounces against all transgressors ¹⁷⁷¹⁷⁷     “A tous transgresseurs.” the condemnation of eternal death, it can do nothing but kill. Widely different is the manner in which life is offered to us in the Gospel, that is, when God reconciles us to himself through free grace, by not imputing our sins, (2 Corinthians 5:19.) It is no ordinary assertion that Peter makes concerning Christ, when he says that he has the words of eternal life; but he ascribes this to Christ as belonging to him alone. Hence follows the second statement which I glanced at a little ago, that as soon as they have gone away from Christ, there remains for them everywhere nothing but death. Certain destruction, therefore, awaits all who, not satisfied with that Teacher, fly to the inventions of men.
