889 He says, When the people saw that Jesus was not there, nor his disciples, they got into the boats, which had come from Tiberias, looking for Jesus; and this is praiseworthy: “Search for the Lord while he can be found” (Is 55:6); “Seek the Lord, and your soul will have life” (Ps 68:33).
890 Once they found him, they questioned him. When they, the people, found him, Christ, on the other side of the sea, they asked him: Rabbi, when did you come here? This can be understood in two ways. In the first way, they were asking about the time only. And then, Chrysostom says, they should be rebuked for their rudeness, because, after such a miracle, they did not ask how he crossed without a boat, but only when he did so. Or, it can be said that by asking when, they wanted to know not just the time, but the other circumstances connected with this miraculous crossing.
891 Note that now, after they have found Christ, they do not wish to make him their king, while before, after he had fed them, they did. They wanted to make him their king then because they were emotionally excited with the joy of their meal; but such emotions quickly pass. So it is that things that we plan according to our emotions do not last; but matters that we arrange by our reason last longer: “A wise man continues on in his wisdom like the sun; a fool changes like the moon” (Sir 27:12); “The work of the wicked will not last” (Prv 11:18)
892 Then (v 26), our Lord begins to mention a food that is spiritual. First, he states a truth about this spiritual food. In the second place, he clears up a misunderstanding (6:41). As to the first he does three things. First, he presents a truth about this spiritual food; secondly, he mentions its origin; and thirdly, he tells them how this spiritual food is to be acquired (6:34). He does two things about the first. First, he explains this spiritual food and its power; in the second place, he tells what this food is (v 28). As to the first, he does two things. First, he rebukes them for their disordered desires; in the second place, he urges them to accept the truth (v 27).
893 He says, Amen, amen, I say to you, that although you seem to be devout, you seek me not because you have seen miracles, but because you have eaten of the bread and have been filled. As if to say: You seek me, not for the sake of the spirit, but for the sake of the flesh, because you hope for more food. As Augustine says, these people represent those who seek Jesus not for himself, but in order to gain certain worldly advantages: as those engaged in some business call on clerics and prelates, not for the sake of Christ, but so that through their intervention they might be advanced into the ranks of those who are important; and like those who hurry to the churches, not for Christ, but because they have been urged to do so by those who are more powerful; and like those who approach our Lord for sacred orders not because they desire the merits of the virtues, but because they are looking for the satisfactions of this present life, as wealth and praise, as Gregory says in his Moralia . This is obvious: for to perform miracles is a work of divine power, but to eat loaves of bread which have been multiplied is temporal. Accordingly, those who do not come to Christ because of the power they see in him, but because they eat his bread, are not serving Christ but their own stomachs, as we see from Philippians (3:19); and again, “He will praise you when you are good to him,” as we read in the Psalm (48:19).
894 He leads them back to the truth by calling their attention to spiritual food, saying, Do not work for the food that perishes, but for that which endures to eternal life. First, he mentions its power; secondly, that it comes from him, which the Son of Man will give you.
895 The power of this food is seen in the fact that it does not perish. In this respect we should point out that material things are likenesses of spiritual things, since they are caused and produced by them; and consequently they resemble spiritual things in some way. Now just as the body is sustained by food, so that which sustains the spirit is called its food, whatever it might be. The food that sustains the body is perishable, since it is converted into the nature of the body; but the food that sustains the spirit is not perishable, because it is not converted into the spirit; rather, the spirit is converted into its food. Hence Augustine says in his Confessions : “I am the food of the great; grow and you will eat me. But you will not change me into yourself, as you do bodily food, but you will be changed into me.”
So our Lord says: work, i.e., seek by your work, or merit by your works, not for the food that perishes, i.e., bodily food: “Food is for the stomach, and the stomach for food, but God will destroy both” (1 Cor 6:13), because we will not always need food; but work for that which, that is, the spiritual food, endures to eternal life. This food is God himself, insofar as he is the Truth which is to be contemplated and the Goodness which is to be loved, which nourish the spirit: “Eat my bread” (Prv 9:5); “Wisdom will feed him with the bread of life and understanding” (Sir 15:5). Again, this food is the obedience to the divine commands: “My food is to do the will of him who sent me” (above 4:34). Also, it is Christ himself: “I am the bread of life” (6:35); “My flesh truly is food and my blood truly is drink” (6:56): and this is so insofar as the flesh of Christ is joined to the Word of God, which is the food by which the angels live. The difference between bodily and spiritual food which he gives here, is like the one he gave before between bodily and spiritual drink: “Whoever drinks this water will be thirsty again, but whoever drinks the water that I give, will never be thirsty again” (4:13). The reason for this is that bodily things are perishable, while spiritual things, and especially God, are eternal.
896 We should note that according to Augustine, in his work, On the Labor of Monks, that certain monks misunderstood our Lord’s saying, Do not work for the food that perishes, and claimed that spiritual men should not perform physical work. But this interpretation is false because Paul, who was most spiritual, worked with his hands: as we read in Ephesians, there he says (4:28): “Let him who stole, steal no longer, rather let him work with his hands.” The correct interpretation, therefore, is that we should direct our work, i.e., our main interest and intention, to seeking the food that leads to eternal life, that is, spiritual goods. In regard to temporal goods, they should not be our principal aim but a subordinate one, that is, they are to be acquired only because of our mortal body, which has to be nourished as long as we are living this present life. So the Apostle speaks against this opinion, saying: “If any one will not work, neither let him eat” (2 Thes 3:10); as if to say: those who maintain that physical work is not to be done should not eat, since eating is physical.
897 Next (v 27), he mentions the one who gives this spiritual food. First, we see the author of this food; secondly, the source of his authority to give us this food. Christ is the author of this spiritual food, and the one who gives it to us. Thus he says, which, that is, the food that does not perish, the Son of Man will give you. If he had said, “the Son of God,” it would not have been unexpected; but he captures their attention by saying that the Son of Man gives this food. Yet the Son of Man gives this food in a spiritual way, because human nature, weakened by sin, found spiritual food distasteful, and was not able to take it in its spirituality. Thus it was necessary for the Son of Man to assume flesh and nourish us with it: “You have prepared a table before me” (Ps 22:5).
898 He adds the source of his authority to give us this food when he says, for on him has God the Father set his seal. As if to say: the Son of Man will give us this food because he surpasses all the sons of men by his unique and preeminent fulness of grace. Thus he says, on him, i.e., on the Son of Man, has God the Father set his seal, i.e., he has significantly distinguished him from others: “God, your God, has anointed you with the oil of gladness above your fellows” (Ps 44:8).
Hilary explains it this way. God set his seal, i.e., impressed with a seal. For when a seal is impressed on wax, the wax retains the entire figure of the seal, just as the Son has received the entire figure of the Father. Now the Son receives from the Father in two ways. One of these ways is eternal, and set his seal does not refer to this way, because when something is sealed the nature receiving the seal is not the same as the nature impressing the seal. Rather, these words should be understood as referring to the mystery of the incarnation, because God the Father has impressed his Word on human nature; this Word who is “the brightness of his glory, and the figure of his substance” (Heb 1:3).
Chrysostom explains it this way. God the Father has set his seal, i.e., God the Father specifically chose Christ to give eternal life to the world: “I came that they may have life” (below 10:10). For when someone is chosen to perform some great task, he is said to be sealed for that task: “After this, the Lord appointed ( designo, appoint; signo, seal, mark) seventy other disciples” (Lk 10:1).
Or, it could be said that God the Father set his seal, i.e., Christ was made known by the Father, by his voice at Christ’s baptism, and by his works, as we saw in the fifth chapter.
899 Next (v 28), we see the nature of spiritual food. First, the Jews pose their question; in the second place, we have the answer of Jesus Christ (v 29).
900 Concerning the first, we should note that the Jews, since they had been taught by the law, believed that only God was eternal. So when Christ said that his food would endure to eternal life, they understood that it would be a divine food. Thus when they question Christ, they do not mention this food, but rather the work of God, saying: What must we do that we may perform the works of God? Indeed, they were not far from the truth, since spiritual food is nothing else than performing and accomplishing the works of God: “What shall I do to gain eternal life?” (Lk 18:18).
901 The Lord’s answer is given when he says: This is the work of God, that you believe in him whom he sent. Here we should reflect that in Romans (4:2), the Apostle distinguished faith from works, saying that Abraham was justified by his faith, not by his works. If this is so, why does our Lord say here that to have faith, i.e., to believe, is a work of God? There are two answers to this. One is that the Apostle is not distinguishing faith from absolutely all works, but only from external works. External works, being performed by our body, are more noticeable, and so the word “works” ordinarily refers to them. But there are other works, interior works, performed within the soul, and these are known only to the wise and those converted in heart.
From another point of view, we can say that to believe can be regarded as included in our external works, not in the sense that it is an external work, but because it is the source of these works.
Thus he significantly says: that you believe in him ( in illum ) . Now it is one thing to say: “I believe in God,” ( credere Deum ), for this indicates the object. It is another thing to say: “I believe God,” ( credere Deo ), for this indicates the one who testifies. And it is still another thing to say: “I believe in God,” ( in Deum ), for this indicates the end. Thus God can be regarded as the object of faith, as the one who testifies, and as the end, but in different ways. For the object of faith can be a creature, as when I believe in the creation of the heavens. Again, a creature can be one who testifies, for I believe Paul ( credo Paulo ) or any of the saints. But only God can be the end of faith, for our mind is directed to God alone as its end. Now the end, since it has the character of a good, is the object of love. Thus, to believe in God ( in Deum ) as in an end is proper to faith living through the love of charity. Faith, living in this way, is the principle of all our good works; and in this sense to believe is said to be a work of God.
902 But if faith is a work of God, how do men do the works of God? Isaiah (26:12) gives us the answer when he says: “You have accomplished all our works for us.” For the fact that we believe, and any good we do, is from God: “It is God who is working in us, both to will and to accomplish” (Phil 2:13). Thus he explicitly says that to believe is a work of God in order to show us that faith is a gift of God, as Ephesians (2:8) maintains.
903 Next, we see the origin of this food. First, we have the question asked by the Jews; secondly, the answer of Christ (v 32). Three things are done about the first: first, the Jews look for a sign; secondly, they decide what it should be; and thirdly, they bring in what is narrated in Scripture.
904 They look for a sign by asking Christ: What sign then are you going to give that we may see and believe you? This question is explained differently by Augustine and by Chrysostom. Chrysostom says that our Lord was leading them to the faith. But the evidence that leads one to the faith are miracles: “Signs were given to unbelievers” (1 Cor 14:22). And so the Jews were looking for a sign in order to believe, for it is their custom to seek such signs: “For Jews demand signs” (1 Cor 14:22). So they say: What sign then are you going to give?
But it seems foolish to ask for a miracle for this reason, for Christ had just performed some in their presence which could lead them to believe, as multiplying the bread and walking on the water. What they were asking was that our Lord always provide them with food. This is clear because the only sign they mention is the one given by Moses to their ancestors for forty years, and they ask in this way that Christ always provide food for them. Thus they say: Our fathers ate manna in the desert. They did not say that God provided their ancestors with the manna, so that they would not seem to be making Christ equal to God. Again, they did not say that Moses fed their ancestors, so they would not seem to be preferring Moses to Christ, trying in this way to influence our Lord. We read of this food: “Man ate the bread of angels” (Ps 77:25).
905 According to Augustine, however, our Lord had said that he would give them food that would endure to eternal life. Thus, he seemed to put himself above Moses. The Jews, on the other hand, considered Moses greater than Christ; so they said: “We know that God spoke to Moses, but we do not know where this man is from” (below 9:29). Accordingly, they required Christ to accomplish greater things than Moses; and so they recall what Moses did, saying: Our Fathers ate manna in the desert. As if to say: What you say about yourself is greater than what Moses did, for you are promising a food that does not perish, while the manna that Moses gave became wormy if saved for the next day. Therefore, if we are to believe you, do something greater than Moses did. Although you have fed five thousand men once with five barley loaves, this is not greater than what Moses did, for he fed all the people with manna from heaven for forty years, and in the desert too: “He gave them the bread of heaven” (Ps 77:24).
