Ambrose of Milan — Commentary on Scripture

John 4:11

The woman saith unto him, Sir, thou hast nothing to draw with, and the well is deep: from whence then hast thou that living water?

This well is clearly the grace of the Spirit, a stream proceeding from the living fountain. The Holy Spirit, then, is also the fountain of eternal life.… This water, the grace of the Spirit, is so refreshing. Who will give this fountain to my breast? Let it spring up in me, let what gives eternal life flow on me. Let that fountain overflow on us and not flow away.… How shall I keep this water so that it does not flow or glide away?

John 4:23 · 2 passages

But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.

What does it mean, then, that the Father is worshiped in Christ, except that the Father is in Christ and the Father speaks in Christ and abides in Christ? He does not abide, indeed, as a body in a body, for God is not a body.… So not an engrafting of a body is meant, but unity of power. Therefore, by unity of power, Christ is jointly worshiped in the Father when God the Father is worshiped in Christ. In the same way then, by unity of the same power the Spirit is jointly worshiped in God when God is worshiped in the Spirit.… When God is said to be worshiped in truth (by the proper meaning of the word itself often expressed after the same manner), it ought to be understood that the Son too is worshiped. So, in the same way, the Spirit is also worshiped because God is worshiped in Spirit. Therefore the Father is worshiped both with the Son and with the Spirit, because the Trinity is worshiped.

In the mystical doctrine, we understand that this well is also referred to there, because there the Samaritan woman, that is, the guardian (the guardian, however, of heavenly precepts), drew divine mysteries from that well, knowing that God is spirit, and is not worshipped in a place but in spirit; and because he is the Messiah, Christ. And therefore, he who is still expected by the Jews has already come. Having heard these things, that woman who appears to be of the Church, recognized the sacraments of the law, and believed.

John 4:34 · 2 passages

Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.

But as Christ is not yet made subject [to the Father], so also is the work of God not yet perfected. For the Son of God said, “My food is to do the will of him who sent me and to complete his work.” How can anyone doubt that the subjection of the Son in me is still in the future when the work of the Father is still unfinished [in me] because I myself am not yet perfect?

The food of a priest is the remission of sins. Therefore, the Prince of priests, Christ, says, “My food is to do the will of him who sent me.” What is the will of God but this: “When you turn and groan, then shall you be saved”?

John 5:4 · 2 passages

For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had.

What did the angel declare in this type but the descent of the Holy Spirit, which was to come to pass in our day and should consecrate the waters when invoked by the prayers of the priest? That angel, then, was a herald of the Holy Spirit, inasmuch as by means of the grace of the Spirit medicine was to be applied to our infirmities of soul and mind. The Spirit, then, has the same ministers as God the Father and Christ. He fills all things, possesses all things, works all and in all in the same manner as God the Father and the Son work.

No one was healed before the angel had descended. Because of those who did not believe, the water was troubled as a sign that the angel had descended. They had a sign, you have faith; for them an angel descended, for you the Holy Spirit; for them the creation was troubled, for you Christ himself, the Lord of creation, worked. Then, one was healed, now all are made whole.… For that pool was as a type so that you might believe that the power of God descends upon this font.

John 5:18

Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.

The Evangelist testifies that in calling himself God’s own Son, Jesus made himself equal to God. For the Jews are not presented as saying, “For this cause we sought to kill him.” Rather, the Evangelist, speaking for himself, says, “For this reason the Jews were seeking all the more to kill him.” Moreover, he has discovered the cause, [in saying] that the Jews were stirred with desire to slay him because, when as God he broke the sabbath and also claimed God as his own Father, Jesus ascribed to himself not only the majesty of divine authority in breaking the sabbath but also, in speaking of his Father, the right pertaining to eternal equality.

John 5:19 · 2 passages

Then answered Jesus and said unto them, Verily, verily, I say unto you, The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise.

The Son, therefore, is both entitled and proved the equal of the Father—a true equality, which both excludes difference of Godhead and discovers, together with the Son, the Father also, to whom the Son is equal. For there is no equality where there is difference, nor again where there is but one person, inasmuch as none is by himself equal to himself. And so, the Evangelist has shown why it is fitting that Christ should call himself the Son of God, that is, make himself equal with God.

Let unbelievers meditate on the fact that, both by nature and sovereignty, the Son is one with the Father and that his power at work is not at cross-purposes with the Father, inasmuch as “whatever the Father does, the Son does as well.” For no one can do in the same way the same work that another had done unless he shares in the unity of the same nature, but at the same time also is not inferior in the method of working.

John 5:22 · 2 passages

For the Father judgeth no man, but hath committed all judgment unto the Son:

But there is fear that the judge may be more severe. Consider who the judge is. Indeed, the Father has given all judgment to Christ. Therefore, can that very one condemn you, whom he redeemed from death, for whom he offered himself, and whose life he knows to be the reward of his own death?

He has given [judgment to the Son], that is to say, not out of largess but in the act of generation. See, then, how unwilling God was that you should dishonor his Son—even to the point that he gave him to be your judge.

John 6:15

When Jesus therefore perceived that they would come and take him by force, to make him a king, he departed again into a mountain himself alone.

By ancient right imperial power had been given by bishops, never assumed, and it was commonly said that emperors had desired the priesthood, rather than priests the imperial power. That Christ withdrew lest He should be made a king. That we had our own power; for the power of a bishop was his weakness. "When I am weak," says the Apostle, "then I become strong."

John 6:27

Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.

Therefore, since Christ was already formed in this [Church], He says, 'Set me as a seal upon your heart, as a seal upon your arm' (Song of Songs 8:6). Christ is a seal on the forehead, a seal on the heart. On the forehead, so that we may always confess [our faith]; on the heart, so that we may always love; a seal on the arm, so that we may always work. Therefore, let His image shine forth in our confession, shine forth in our love, shine forth in our deeds and actions; so that, if possible, His whole appearance may be expressed in us. He himself is our head, because the head of man is Christ: he himself is our eye, so that through him we may see the Father: he himself is our voice, through whom we speak to the Father: he himself is our right hand, through whom we offer our sacrifice to God the Father: he himself is also our seal, which is a sign of perfection and charity, because the loving Father has sealed the Son, as we read: "Whom the Father has sealed, God" (John 6:27). Therefore, Christ is our charity. Good love, when it offered itself for our sins: good love, which forgave sin…

John 6:35

And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.

Who then is rich, unless where the height of riches is wisdom and knowledge of God? Who is rich but the Lord Jesus, who always abounds, and never fails? The poor came into this world, and has abounded to all, and has filled all. How great is he in riches, who by his poverty has made all rich! But he became poor for our sake, being rich with the Father. He became poor so that he might deliver us from poverty; as the Apostle teaches, saying: "For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that by his poverty you might become rich." His poverty enriches, heals wounds, satisfies hunger, gives life to the dead, and raises the buried. Therefore, he is a treasure, and his is the abundant bread. And whoever eats this rich bread will never hunger. He gave this bread to the apostles, so that they would distribute it to the people who believed; and today he gives us the same bread, which the priest consecrates daily with his words. Therefore, this bread has become the food of the saints.

John 6:44

No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.

And you say that the Son of God is subject by reason of weakness—the Son, to whom the Father brings men and women that he may raise them up in the last day. Does this seem in your eyes to be subjection where the kingdom is prepared for the Father and the Father brings it to the Son? There is no place for perversion of words since the Son gives the kingdom to the Father and none is preferred before him. For as the Father gives to the Son, and the Son, again, to the Father, here are plain proofs of love and regard: seeing that they [i.e., Father and Son] give to each other that neither he who receives obtains, as it were, what was another’s, nor he that gives loses anything.

John 6:49

Your fathers did eat manna in the wilderness, and are dead.

It has been proven that the sacraments of the church are more ancient; now realize that they are more powerful. In very fact it is a marvelous thing that God rained manna on the ancestors and they were fed by daily nourishment from heaven. Therefore, it is said, “Humankind has eaten the bread of angels.” And yet all those who ate that bread died in the desert, but this food that you receive, this “living bread, which came down from heaven,” furnishes the substance of eternal life, and whoever eats this bread “will not die forever,” for it is the body of Christ.

John 6:50

This is the bread which cometh down from heaven, that a man may eat thereof, and not die.

We are able to receive the Lord Himself, who gave His flesh for us, as He Himself says: "I am the bread of life. Your fathers ate the manna in the desert, and they died: but this is the bread which comes down from heaven, that if any man eat of it, he may not die" (John 6:48-50). And so that no one may think that He is speaking of the death which comes through the separation of soul and body, and may doubt with reason, since he knows that the holy apostles died this death, He added: "I am the living bread, which came down from heaven. If anyone eats of this, he will live forever" (John 6:51-52): that is, I did not speak about temporal life above, nor about the death of this life, in which even if anyone dies, nevertheless if he receives my bread, he will live forever. For he who receives, proves himself: but he who receives will not die the death of a sinner, because this bread is the forgiveness of sins.

John 6:51

I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.

The mysteries of the more perfect Sacraments are of one kind; for the Scripture says, "Eye hath not seen, nor ear heard, neither hath entered into the heart of man the things which God hath prepared for them that love Him." Of another kind are the things which the prophets have announced concerning future glory, unto whom it was revealed, and to whom the saints have preached the Gospel with the Holy Ghost sent down from heaven, which things the Angels desired to look into. Of another kind again are those mysteries wherein is the redemption of the world, the remission of sins, the distribution of graces, the participation of the Sacraments: when you receive these you will wonder that a gift so transcendent should have been bestowed on man, as to make the manna which we wonder should have been rained down from heaven on the Jews seem to you to have possessed neither so much grace nor so much efficacy towards salvation. For all who received this manna in the wilderness died, save Joshua the son of Nun, and Caleb, whereas he who tastes this Sacrament shall never die.

John 6:63

It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.

Learn now that as the Father is the Fount of life, so, too, many have stated that the Son is signified as the Fount of life. This is why he says that with you, almighty God, your Son is the Fount of life. That is the Fount of the Holy Spirit, for the Spirit is life, as the Lord says: “The words that I have spoken to you are spirit and life,” for where the Spirit is, there also is life. And where life is, there is also the Holy Spirit.
