Amen, amen I say unto you: He that believeth in me, hath everlasting life.

“(Tr. xxvi. s. 10.) Our Lord wishes to reveal what He is; Verily, verily, I say unto you, He that believeth on Me, hath everlasting life. As if He said; He that believeth on Me hath Me: but what is it to have Me? It is to have eternal life: for the Word which was in the beginning with God is life eternal, and the life was the light of men. Life underwent death, that life might kill death.”

“With the murmuring of the Jews checked, the Lord accordingly satisfies the doubt that had arisen in the hearts of the Jews concerning the word he had spoken, namely, I am the bread which came down from heaven, where he intends to prove that this is true of himself; and he argues thus: that bread came down from heaven which gives life to the world; but I am the bread giving life to the world; therefore I am the bread which came down from heaven, and so on. Concerning this he does three things. First, he sets down, as it were, the minor premise of his argument, namely, I am the bread of life; second, he sets down the major premise, namely, that the bread which came down from heaven ought to give life, at the place, your fathers ate manna in the desert, and they died; third, he sets down the conclusion, at the place, I am the living bread. Concerning the first he does two things. First he makes clear his proposal; second he brings forward what was intended as, so to speak, proven, at the place, I am the bread of life. His proposal is to show that he is the bread of life. Now bread gives life inasmuch as it is taken. But it is agreed that whoever believes in Christ takes him within himself, according to that word of Ephesians 3:17: that Christ may dwell through faith in our hearts. If therefore he who believes in Christ has life, it is clear that by eating this bread he is given life; therefore this bread is the bread of life. And this is what he says: Amen, amen, I say to you, whoever believes in me — namely with formed faith, which perfects not only the intellect but also the affection (for one does not tend toward the thing believed unless one loves it) — has eternal life. Now Christ is in us in two ways: namely in the intellect through faith, inasmuch as it is faith; and in the affection through charity, which informs faith: 1 John 4:16, whoever abides in charity abides in God, and God in him. Whoever therefore believes in Christ in such a way as to tend toward him has him in affection and in intellect; and if we add that Christ is eternal life, as is said in 1 John 5:20, that we may be in his true Son Jesus Christ: this is the true God and eternal life; and above, John 1:4, in him was life — we can infer that whoever believes in Christ has eternal life. He has it, I say, in cause and in hope, and will one day have it in reality. Having made clear his proposal, he brings forward what was intended, when he says, I am the bread of life, that is, giving life, as evidently follows from what has been said. Concerning this bread, Genesis 49:20: Asher, his bread is fat, he shall yield delights — namely of eternal life — to kings. Accordingly, when he says, your fathers ate manna in the desert, and they died, he sets down the major premise: namely, that to give life is the effect of bread descending from heaven. And first he prefaces the manifestation of the proposal; second he sets down what was intended, at the place, this is the bread which comes down from heaven. Now he makes clear his proposal by its contrary. For it was said above that Moses did not give the Jews bread from heaven, but only from the air; but all bread which is not from the true heaven cannot give sufficient life; therefore this is proper to heavenly bread, that it gives life. And therefore the bread of Moses, in which you take pride, does not give life; and this he proves when he says, your fathers ate manna in the desert, and they died. Here he first reproaches their vice, when he says your fathers, etc. — whose sons you are, not only according to the origin of the flesh, but also according to the imitation of their works, because you are murmurers, just as they also murmured in their tents, as is said in Psalm 105:25; and therefore he said to them, Matthew 23:32, fill up the measure of your fathers. Whence, as Augustine says, the people are said to have offended God in no matter more than by murmuring against God. Second, he insinuates the short span of time, when he says in the desert: for it was not a long time in which the manna was given to them, nor did it come with them into the land of promise, but only in the desert, as is said in Joshua 5:12. This bread, however, preserves and refreshes forever. Third, he makes clear the deficiency of the food, because it did not preserve unfailing life; hence he says, and they died. For, as is found in Joshua 5, all who murmured, except Joshua and Caleb, died in the desert. Whence this was also the cause of the second circumcision, namely that all the people who went out from Egypt died in the desert, as is said in the same place. But it is asked of what death God here speaks. For if he speaks of bodily death, there will be no difference between that bread which was in the desert and our bread which came down from heaven, because even Christians who take this one die bodily. But if he speaks of spiritual death, it is clear that here and there some die spiritually and some do not. For Moses, and many who pleased God, did not die, although others died. Likewise, those who take this bread unworthily also die spiritually; 1 Corinthians 11:29: for he who eats and drinks unworthily eats and drinks judgment to himself. To this it must be said that that food agrees with our spiritual food. They agree indeed as to this, that each signifies the same thing: for both that one and this one signify Christ, on account of which it is called the same food; 1 Corinthians 10:3: all ate the same food. He says the same because both are a figure of spiritual food. But they differ, because that one only prefigured, whereas this bread contains what it prefigures, namely Christ himself. It must therefore be said that each of these foods can be taken in two ways: either as to the sign only, that is, that it is taken only as food, its meaning not understood; and by this neither spiritual nor bodily death is removed. Or it can be taken as to both, that is, that the visible food is so taken that the spiritual food is understood, and is spiritually tasted, so that it spiritually satisfies; and in this way those who ate the manna spiritually did not die spiritually. But those also who eat the Eucharist spiritually, and now live spiritually without sin, will also live bodily forever. Our food, therefore, has more than their food, because it contains in itself what it prefigures. Having made clear the proposal, therefore, he brings forward what was intended; hence he says, this is the bread which comes down from heaven. And according to the Gloss, he says this pointing to himself. But this is not the Lord's meaning, because since he immediately adds, I am the living bread which came down from heaven, it would be a repetition of words. It must therefore be said that the Lord intends this: namely, to say that that bread comes down from heaven which can do this, namely give life; but I am such; therefore I am the bread which comes down from heaven. And the reason that bread coming down from heaven gives unfailing life is that all food nourishes according to the property of its own nature; but heavenly things are incorruptible; and therefore, because that food is heavenly, it is not corrupted, and as long as it remains it gives life. Whoever therefore eats of it will not die. Just as if some bodily food were never corrupted, giving nourishment, it would always give life. And therefore this bread was signified by the tree of life which was in the middle of paradise, in a certain way giving life forever, according to that word of Genesis 3:22: now therefore lest perhaps he put forth his hand, and take of the tree of life, and eat, and live forever. If therefore this is the effect of this bread, namely that whoever eats of it does not die, and I am such: therefore, and so on. I am the living bread, etc. Concerning this, then, he does two things. First he speaks of himself in general; second specifically, at the place, and the bread which I will give is my flesh. Concerning the first he does two things. First he concludes the origin of himself. Second he shows his power, at the place, if anyone eats of this bread, he will live forever. He said, then, I am the living bread, and therefore I can give life. For bodily bread does not give life forever, because it does not have life in itself; but it gives life, once altered and converted into nourishment, by the power of the one living. Who came down from heaven: this was expounded above, in chapter 3, namely how he came down. And by this the heresies of those saying Christ was a mere man are excluded, because according to this he would not have come down from heaven. Now his power is to give eternal life; and therefore he says, if anyone eats of this bread — spiritually, that is — he will live, not only in the present through faith and righteousness, but forever; below, John 11:26: everyone who lives and believes in me will never die. Accordingly he speaks of the body, when he says, and the bread which I will give is my flesh. For he had said that he was the living bread, and lest it be understood that this belonged to him only inasmuch as he is the Word, or according to the soul only, he therefore shows that his flesh also is life-giving: for it is the instrument of his divinity; hence, since an instrument acts by the power of the agent, just as the divinity of Christ is life-giving, so also, as Damascene says, the flesh, by the power of the Word joined to it, gives life; hence Christ by his touch healed the sick. Thus, then, what he said above, I am the living bread, pertains to the power of the Word; but what he adds here pertains to the communion of his body, namely to the sacrament of the Eucharist. Here we can consider four things concerning this sacrament: namely, its species, the authority of its institutor, the truth of the sacrament, and its usefulness. The species of the sacrament indeed: this is bread; Proverbs 9:5: come, and eat my bread. The reason for this is that this is the sacrament of the body of Christ; but the body of Christ is the Church, which rises into the unity of one body out of many faithful; hence this is the sacrament of the unity of the Church; Romans 12:5: we are all one body. Because, then, bread is made up of many grains, therefore this species is fitting for this sacrament; and therefore he says, and the bread which I will give is my flesh. The author of this sacrament is Christ: for although the priest consecrates, nevertheless Christ himself gives power to the sacrament, because even the priest himself consecrates in the person of Christ. Hence in the other sacraments the priest uses his own words, or those of the Church, but in this one he uses the words of Christ: because just as Christ gave his own body to death by his own will, so by his own power he gives himself as food; Matthew 26:26: taking bread, he blessed, and broke it, and gave it to his disciples, and said, take and eat: this is my body. And therefore he says, which I will give: and he says I will give, because this sacrament was not yet instituted. Now the truth of this sacrament is insinuated when he says, is my flesh. He does not say, however, signifies my flesh, but is my flesh; because according to the truth of the matter, what is taken is truly the body of Christ; Job 31:31: if the men of my tabernacle have not said: who will give us of his flesh, that we may be filled? But since in this sacrament the whole Christ is contained, why did he say only, is my flesh? In answer to this, it must be known that in that mystical sacrament the whole Christ is contained according to truth, but the body is there by force of the conversion, while the divinity and the soul are there by natural concomitance. For if it be granted — though impossible — that the divinity were separated from the body of Christ, the divinity would no longer be in the sacrament. Likewise also, if someone had consecrated during the three days of his death, the soul of Christ would not have been there, but such a body as it was on the cross, or in the tomb. The reason he rather says flesh is that, since this sacrament is a remembrance of the Lord's passion, according to that word of 1 Corinthians 11:26: as often as you shall eat this bread, and drink the cup, you shall show forth the death of the Lord — and the passion of Christ was from weakness, according to that word of 2 Corinthians 13:4: he died from weakness, etc. — therefore, so that the weakness from which he died might be insinuated, he rather says, is my flesh: for this word signifies weakness. Now the usefulness of this sacrament is great, and universal. Great indeed, because it works in us now spiritual life, and at length eternal life, as has been said. For, as appears from what has been said above, since this sacrament is of the Lord's passion, it contains in itself Christ having suffered; hence whatever is the effect of the Lord's passion is also wholly the effect of this sacrament. For this sacrament is nothing other than the application of the Lord's passion to us. For it was not fitting that Christ should always be with us according to his presence; and therefore he willed to supply for this through this sacrament. Whence it is clear that the destruction of death, which Christ destroyed by dying, and the reparation of life, which he effected by rising, is the effect of this sacrament. Universal, however, because the life which it confers is not only the life of one man, but, as far as it is in itself, of the whole world: for which the death of Christ is sufficient; 1 John 2:2: he is the propitiation for our sins, and not for ours only, but also for those of the whole world. It must be noted, however, that it is one way in this sacrament, and another way in the others: for the other sacraments have singular effects, as in Baptism only the one baptized receives grace; but in the immolation of this sacrament the effect is universal, because not only does the priest obtain the effect, but also those for whom he prays, and the whole Church, both of the living and of the dead. The reason for this is that in it is contained the universal cause itself of all the sacraments, namely Christ. Nor yet, if a layman takes this sacrament, does it profit others as far as concerns the work performed, inasmuch as it is considered as reception; although from the intention of the one performing it and of the one receiving it, it can be communicated to all to whom he directs his intention. From which it is clear that laypeople who receive the Eucharist for those who are in Purgatory are in error.”

“I am that bread of life. See Gill on Joh 6:35. . John 6:49 joh 6:49 joh 6:49 joh 6:49Your fathers did eat manna in the wilderness,.... All the while they were in the wilderness, for the space of forty years, till they came to the borders of the land of Canaan; this was their only food on which they lived, during their travels through the wilderness. It is observable, that Christ says, not "our fathers", but "your fathers"; for though Christ, as concerning the flesh, came of these fathers, yet in every sense they were rather theirs than his; because regard may be had to such of them more especially who ate the manna as common food, and not as spiritual meat, as typical of the Messiah, as others did; and whom these, their offspring, did very much resemble. Though perhaps the reason of the use of this phrase may be, because the Jews themselves had used it in Joh 6:31, and Christ takes it up from them. And are dead. This food, though it supported them in life for a while, could not preserve them from a corporeal death, and still less from an eternal one: for some of them not only died the first, but the second death.”

“Hath everlasting life - He is entitled to this, on his believing me to be the Messiah, and trusting in me alone for salvation. Our blessed Lord recapitulates here what he had said in the preceding discourse. The person who is saved is, 1. drawn by the Father; 2. hears his instructions; 3. accepts the salvation offered; 4. is given to Christ Jesus, that he may be justified by faith; 5. is nourished by the bread of life; 6. perseveres in the faith; 7. is not lost, but is raised up at the last day; and 8. is made a partaker of eternal life.”

“The text is in the present tense. Without the reception of the flesh and blood of Christ — at least in desire — the soul has not the life of grace, and has no title to everlasting life. The interchange of tenses, which is so frequent in Hebrew, has given occasion to the Latin interpreter to use them, one for the other. " Inasmuch as the flesh of the Saviour, being united with the Word of God, which is naturally the life, has beei made life-giving, when we eat it, then we have life in us, being unite with that which has been made life." St. Cyril Alex.”
