John 3:29

29 He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled.
Commentaries
Clement of Alexandriaon John 3:29AD 215
Now the shoes which the Father bids the servant give to the repentant son who has be-taken himself to Him, do not impede or drag to the earth (for the earthly tabernacle weighs down the anxious mind); but they are buoyant, and ascending, and waft to heaven, and serve as such a ladder and chariot as he requires who has turned his mind towards the Father. For, beautiful after being first beautifully adorned with all these things without, he enters into the gladness within. For "Bring out" was said by Him who had first said, "While he was yet a great way off, he ran and fell upon his neck." For it is here that all the preparation for entrance to the marriage to which we are invited must be accomplished. He, then, who has been made ready to enter will say, "This my joy is fulfilled." But the unlovely and unsightly man will hear, "Friend, how camest thou in here, without having a wedding garment?"
Ambrose of Milanon John 3:29AD 397
That is, he alone is the husband of the Church, he is the expectation of the nations, offering to him the bond of nuptial grace, the prophets have loosed their sandals in his presence. He is the bridegroom, I am the friend of the bridegroom: I rejoice because he has come, because I hear the bridal voice, because no longer do we endure the harsh punishments of sins, the severe torments of the Law, but rather the forgiveness of sins, the voice of joy, the sound of gladness, we have heard the exultation of the festive nuptials.
John Chrysostomon John 3:29AD 407
"He that hath the bride is the bridegroom; but the friend of the bridegroom which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice."

"But how doth he who said, 'whose shoe's latchet I am not worthy to unloose,' now call himself His 'friend'?" It is not to exalt himself, nor boastingly, that he saith this, but from desire to show that he too most forwards this, (i.e. the exaltation of Christ,) and that these things come to pass not against his will or to his grief, but that he desires and is eager for them, and that it was with a special view to them that all his actions had been performed; and this he has very wisely shown by the term "friend." For on occasions like marriages, the servants of the bridegroom are not so glad and joyful as his "friends." It was not from any desire to prove equality of honor, (away with the thought,) but only excess of pleasure, and moreover from condescension to their weakness that he calleth himself "friend." For his service he before declared by saying, "I am sent before Him." On this account, and because they thought that he was vexed at what had taken place, he called himself the "friend of the Bridegroom," to show that he was not only not vexed, but that he even greatly rejoiced. "For," saith he, "I came to effect this, and am so far from grieving at what has been done, that had it not come to pass, I should then have been greatly grieved. Had the bride not come to the Bridegroom, then I should have been grieved, but not now, since my task has been accomplished. When His servants are advancing, we are they who gain the honor for that which we desired hath come to pass, and the bride knoweth the Bridegroom, and ye are witnesses of it when ye say, 'All men come unto Him.' This I earnestly desired, I did all to this end; and now when I see that it has come to pass, I am glad, and rejoice, and leap for joy."
John Chrysostomon John 3:29AD 407
But what meaneth, "He which standeth and heareth Him rejoiceth greatly, because of the Bridegroom's voice"? He transfers the expression from the parable to the subject in hand; for after mentioning the bridegroom and the bride, he shows how the bride is brought home, that is, by a "Voice" and teaching. For thus the Church is wedded to God; and therefore Paul saith, "Faith cometh by hearing, and hearing by the word of God." "At this 'Voice,'" saith he, "I rejoice." And not without a cause doth he put "who standeth," but to show that his office had ceased, that he had given over to Him "the Bride," and must for the future stand and hear Him; that he was a servant and minister; that his good hope and his joy was now accomplished. Therefore he saith,

"This my joy therefore is fulfilled."

That is to say, "The work is finished which was to be done by me, for the future I can do nothing more." Then, to prevent increase of jealous feeling, not then only, but for the future, he tells them also of what should come to pass, confirming this too by what he had already said and done.
Augustine of Hippoon John 3:29AD 430
There were prophets before John, and many, and great, and holy, worthy of God, full of God, announcers of the Savior; witnesses of the truth. However, it could not be said of any of them what was said of John: Among those born of women, none has arisen greater than John the Baptist. So what does this greatness placed before greatness mean? For the testimony of great humility. For he was so great that Christ could have been thought. John could have exploited the error of men and not exerted himself to persuade that he was the Christ, because those who heard and saw him, already thought he was without him saying it. There was no need for him to sow error, but to confirm it. But that humble friend of the bridegroom, zealous for the bridegroom, not substituting himself as the adulterer for the bridegroom, bears testimony to his friend, and commends him who was truly the bridegroom to the bride: that he might be loved in him, he hates to be loved instead of him. "He who has the bride is the bridegroom," he says. And as if you might say, "Who are you then?" He adds, "But the friend of the bridegroom stands and hears him, and rejoices greatly because of the bridegroom's voice." He stands and hears: the disciple hears the master; because he hears, he stands; for if he does not hear, he falls. Hence the greatness of John is especially commended; for when he could have been thought to be Christ, he preferred to bear testimony to Christ, to commend him; to humble himself rather than to be taken instead of him, and to deceive others.

Augustine of Hippoon John 3:29AD 430
(Tr. xiii. c. 12) As if He said, She is not My spouse. But dost thou therefore not rejoice in the marriage? Yea, I rejoice, he saith, because I am the friend of the Bridegroom.

(Tr. xiii) But wherefore doth he stand? Because he falleth not, by reason of his humility. A sure ground this to stand upon, Whose shoe's latchet I am not worthy to unloose. Again; He standeth, and heareth Him. So then if he falleth, he heareth Him not. Therefore the friend of the Bridegroom ought to stand and hear, i. e. to abide in the grace which he hath received, and to hear the voice in which he rejoiceth. I rejoice not, he saith, because of my own voice, but because of the Bridegroom's voice. I rejoice; I in hearing, He in speaking; I am the ear, He the Word. For he who guards the bride or wife of his friend, takes care that she love none else; if he wish to be loved himself in the stead of his friend, and to enjoy her who was entrusted to him, how detestable doth he appear to the whole world! Yet many are the adulterers I see, who would fain possess themselves of the spouse who was bought at so great a price, and who aim by their words at being loved themselves instead of the Bridegroom.

(Tr. xiv. c. 3) Or thus; This my Joy is fulfilled, i. e. my joy at hearing the Bridegroom's voice. I have my gift; I claim no more, lest I lose that which I have received. He who would rejoice in himself, hath sorrow; but he who would rejoice in the Lord, shall ever rejoice, because God is everlasting.
Augustine of Hippoon John 3:29AD 430
"He that hath the bride is the Bridegroom; but the friend of the Bridegroom, who standeth and heareth Him, rejoiceth greatly because of the Bridegroom's voice." Not of himself did he give himself joy. He that will have joy of himself shall be sad; but he that will have his joy of God will ever rejoice, because God is everlasting. Dost thou desire to have everlasting joy? Cleave to Him who is everlasting. Such an one John declared himself to be. "Because of the Bridegroom's voice, the friend of the Bridegroom rejoiceth," not because of his own voice, and "standeth and heareth." Therefore, if he falls, he heareth Him not: for of a certain one who fell it is said, "And he stood not in the truth;" this is said of the devil. It behoves the Bridegroom's friend, then, "to stand and to hear." What is it to stand? It is to abide in His grace, which he received. And he hears a voice at which he rejoices. Such was John: he knew whereof he rejoiced; he did not arrogate to himself to be what he was not; he knew himself as one enlightened, not the enlightener.
Augustine of Hippoon John 3:29AD 430
"This my joy therefore is fulfilled." What is his joy? To rejoice at the Bridegroom's voice. It is fulfilled in me, I bare my grace; more I do not assume to myself, lest also I lose what I have received. What is this joy? "With joy rejoiceth for the Bridegroom's voice." A man may understand, then, that he ought not to rejoice of his own wisdom, but of the wisdom which he has received from God. Let him ask nothing more, and he loses not what he found. For many, in that they affirmed themselves to be wise, became fools. The apostle convicts them, and says of them, "Because that which is known of God is manifest to them; for God has showed it unto them." Hear ye what he says of certain unthankful, ungodly men: "For the invisible things of Him from the creation of the world are seen, being understood by the things that are made, His eternal power likewise, and Godhead; so that they are without excuse." Why without excuse? "Because, knowing God" (he said not, "because they knew Him not"), "they glorified Him not as God, nor were thankful; but became vain in their imaginations, and their foolish heart was darkened: professing themselves to be wise, they became fools." If they had known God, they had known at the same time that God, and none other, had made them wise; and they would not then attribute to themselves that which they did not have from themselves, but to Him from whom they had received it. But by their unthankfulness they became fools. Therefore, what God gave freely, He took from the unthankful. John would not be this; he would be thankful: he confessed to have received, and declared that he rejoiced for the Bridegroom's voice, saying, "Therefore this my joy is fulfilled."
Augustine of Hippoon John 3:29AD 430
But hear a far stronger, a far more expressive testimony. See ye what it is we are treating of; see ye that to love any person in place of Christ is adultery. Why do I say this? Let us attend to the voice of John. People could be mistaken in him, could think him to be the person he was not. He rejects the false honor, in order to hold the truth complete. See what he declares Christ to be; what does he say himself is? "He that hath the bride is the bridegroom." Be chaste, love the bridegroom. But what art thou, who sayest to us, "He that hath the bride is the bridegroom? But the friend of the bridegroom, who standeth and heareth him, rejoiceth greatly because of the bridegroom's voice." The Lord our God will help me in proportion to the tumult of my heart, for it is full of sadness, to utter the grief I feel; but I beseech you by Christ Himself to imagine in thought what it will not be possible for me to utter; for I know that my grief cannot be expressed with befitting impressiveness. Now I see many adulterers who desire to get possession of the bride, purchased at so great a price, loved while deformed that she might be made fair, having been purchased and delivered and adorned by such an one; and those adulterers strive with their words to be loved instead of the bridegroom. Of that One it is said, "This is He that baptizeth." Who is he that goes forth from us and says, "I am he that baptizeth"? Who is he that goes forth from us and says, "That is holy which I give"? Who is he that goes hence and says, "It is good for thee to be born of me"? Let us hear the friend of the bridegroom, not the adulterers against the bridegroom; let us hear one jealous, but not for himself.
Augustine of Hippoon John 3:29AD 430
Brethren, return in thought to your own homes. I speak of carnal, I speak of earthly things; I speak after the manner of men, for the infirmity of your flesh. Many of you have, many of you wish to have, many, though you wish not to have, still have had wives; many who do not at all wish to have wives, are born of the wives of your fathers. This is a feeling that touches every heart. There is no man so alien from mankind in human affairs as not to feel what I say. Suppose that a man, having set out on a journey, had commended his bride to the care of his friend: "See, I pray thee, thou art my dear friend; see to it, lest in my absence some other may perchance be loved in my stead." Then what sort of a person must he be, who, while the guardian of the bride or wife of his friend, does indeed endeavor that none other be loved, but if he wishes himself to be loved instead of his friend, and desires to enjoy her who was committed to his care, how detestable must he appear to all mankind! Let him see her gazing out of the window, or joking with some one somewhat too heedlessly, he forbids her as one who is jealous. I see him jealous, but let me see for whom he is jealous; whether for his absent friend or for his present self. Think that our Lord Jesus Christ has done this. He has committed His bride to the care of His friend; He has set out on a journey to a far country to receive a kingdom, as He says Himself in the Gospel, but yet is present in His majesty. Let the friend who has gone beyond the sea be deceived; and if he is deceived, woe to him who deceives! Why do men attempt to deceive God,-God who looks at the hearts of all, and searches the secrets of all?
Augustine of Hippoon John 3:29AD 430
Let us return and see what this John saith: "He that hath the bride is the bridegroom;" she is not my bride. And dost thou not rejoice in the marriage? Yea, saith he, I do rejoice: "But the friend of the bridegroom, who standeth and heareth him, rejoiceth greatly because of the voice of the bridegroom." Not because of mine own voice, saith he, do I rejoice, but because of the Bridegroom's voice. I am in the place of hearer; He, of speaker: I am as one that must be enlightened, He is the light; I am as the ear, He is the word. Therefore the friend of the Bridegroom standeth and heareth Him. Why standeth? Because he falls not. How falls not? Because he is humble. See him standing on solid ground; "I am not worthy to loose the latchet of His shoe." Thou doest well to be humble; deservedly thou dost not fall; deservedly thou standest, and hearest Him, and rejoicest greatly for the Bridegroom's voice. So also the apostle is the Bridegroom's friend; he too is jealous, not for himself, but for the Bridegroom. Hear his voice when he is jealous: "I am jealous over you," said he, "with the jealousy of God:" not with my own, nor for myself, but with the jealousy of God. Why? How? Over whom art thou jealous, and for whom? "For I have espoused you to one husband, to present a chaste virgin to Christ." Why dost thou fear, then? Why art thou jealous? "I fear," saith he, "lest, as the serpent beguiled Eve by his subtilty, so your minds should be corrupted from the chastity which is in Christ." The whole Church is called a virgin. You see that the members of the Church are divers, that they are endowed with and do rejoice in divers gifts: some men wedded, some women wedded; some are widowers who seek no more to have wives, some are widows who seek no more to have husbands; some men preserve continence from their youth, some women have vowed their virginity to God: divers are the gifts, but all these are one virgin. Where is this virginity, for it is not in the body. It belongs to few women; and if virginity can be said of men, to few men in the Church belongs a holy integrity even of body; yet one such is a more honorable member. Other members, however, preserve virginity, not in body, but all in mind. What is the virginity of the mind? Entire faith, firm hope, sincere charity. This is the virginity which he, who was jealous for the Bridegroom, feared might be corrupted by the serpent. For, just as the bodily member is marred in a certain part, so the seduction of the tongue defiles the virginity of the heart. Let her who does not desire without cause to keep virginity of body, see to it that she be not corrupted in mind.
Augustine of Hippoon John 3:29AD 430
What shall I say, then, brethren? Even the heretics have virgins, and there are many virgins among heretics. Let us see whether they love the Bridegroom, so that this virginity may be guarded. For whom is it guarded? "For Christ." Let us see if it be for Christ, and not for Donatus: let us see for whom this virginity is preserved: you can easily prove. Behold, I show you the Bridegroom, for He shows Himself. John bears witness to Him: "This is He that baptizeth." O thou virgin, if for this Bridegroom thou preservest thy virginity, why runnest thou to him who says, "I am he that baptizeth," while the friend of the Bridegroom tells thee, "This is He that baptizeth"? Again, thy Bridegroom possesseth the whole world; why, then, shouldst thou be defiled with a part of it? Who is the Bridegroom? "For God is King of all the earth." This thy Bridegroom possesses the whole, because He purchased the whole. See at what price He purchased it, that thou mayest understand what He has purchased. What price has He given? He gave His blood. Where gave He, where shed He, His blood? In His passion.
Augustine of Hippoon John 3:29AD 430
Evidently, then, my brethren, it profits those men nothing to keep virginity, to have continence, to give alms. All those doings which are praised in the Church profit them nothing; because they rend unity, namely, that "coat" of charity. What do they? Many among them are eloquent; great tongues, streams of tongues. Do they speak like angels? Let them hear the friend of the Bridegroom, jealous for the Bridegroom, not for himself: "Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal."
Augustine of Hippoon John 3:29AD 430
But what say they? "We have baptism." Thou hast, but not thine. It is one thing to have, another to own. Baptism thou hast, for thou hast received to be baptized, received as one enlightened, provided thou be not darkened of thyself; and when thou givest, thou givest as a minister, not as owner; as a herald proclaiming, not as a judge. The judge speaks through the herald, and nevertheless it is not written in the registers, "The herald said," but, "The judge said." Therefore see if what thou givest is thine by authority. But if thou hast received, confess with the friend of the Bridegroom, "A man cannot receive anything, except it be given him from heaven." Confess with the friend of the Bridegroom, "He that hath the bride is the Bridegroom; but the friend of the Bridegroom standeth and heareth Him." But O, would thou didst stand and hear Him, and not fall, to hear thyself! For by hearing Him, thou wouldst stand and hear; for thou wilt speak, and thy head is puffed with pride. I, saith the Church, if I am the bride, if I have received pledges, if I have been redeemed at the price of that blood, do hear the voice of the Bridegroom; and I do hear the voice of the Bridegroom's friend too, if he give glory to my Bridegroom, not to himself. Let the friend speak: "He that hath the bride is the Bridegroom; but the friend of the Bridegroom standeth and heareth Him, and rejoices greatly because of the voice of the Bridegroom." Behold, thou hast sacraments; and I grant that thou hast. Thou hast the form, but thou art a branch cut off from the vine; thou hast a form, I want the root. There is no fruit of the form, except where there is a root; but where is the root but in charity? Hear the form of the cut-off branches; let Paul speak: "Though I know all mysteries," saith he, "and have all prophecy, and all faith" (and how great a faith!), "so as to remove mountains, and have not charity, I am nothing."
Augustine of Hippoon John 3:29AD 430
Let no man tell you fables, then. "Pontius wrought a miracle; and Donatus prayed, and God answered him from heaven." In the first place, either they are deceived, or they deceive. In the last place, grant that he removes mountains: "And have not charity," saith the apostle, "I am nothing." Let us see whether he has charity. I would believe that he had, if he had not divided unity. For against those whom I may call marvel-workers, my God has put me on my guard, saying, "In the last times there shall arise false prophets, doing signs and wonders, to lead into error, if it were possible, even the elect: Lo, I have foretold it to you." Therefore the Bridegroom has cautioned us, that we ought not to be deceived even by miracles. Sometimes, indeed, a deserter frightens a plain countryman; but whether he is of the camp, and whether he is the better of that character with which he is marked, is what he who would not be frightened or seduced attends to. Let us then, my brethren, hold unity: without unity, even he who works miracles is nothing. The people Israel was in unity, and yet wrought no miracles: Pharaoh's magicians were out of unity, and yet they wrought the like works as Moses. The people Israel, as I have said, wrought no miracles. Who were saved with God-they who did, or they who did not, work miracles? The Apostle Peter raised a dead person: Simon Magus did many things: there were there certain Christians who were not able to do either what Peter did or what Simon did; and wherein did they rejoice? In this, that their names were written in heaven. For this is what our Lord Jesus Christ said to the disciples on their return, because of the faith of the Gentiles. The disciples, in truth, themselves said, boasting, "Behold, Lord, in Thy name even the devils are subject to us." Rightly indeed they confessed, they brought the honor to the name of Christ; and yet what does He say to them? "Do not ye glory in this, that the devils are subject to you; but rejoice that your names are written in heaven." Peter cast out devils. Some old widow, some lay person or other, having charity, and holding the integrity of faith, forsooth does not do this. Peter is the eye in the body, that man is the finger, yet is he in the same body in which Peter is; and if the finger has less power than the eye, yet it is not cut off from the body. Better is it to be a finger and to be in the body, than to be an eye and to be plucked out of the body.
Augustine of Hippoon John 3:29AD 430
Therefore, my brethren, let no man deceive you, let no man seduce you: love the peace of Christ, who was crucified for you, whilst He was God. Paul says, "Neither he that planteth is anything, neither he that watereth, but God who giveth the increase." And does any of us say that he is something? If we say that we are something, and give not the glory to Him, we are adulterers; we desire ourselves to be loved, not the Bridegroom. Love ye Christ, and us in Him, in whom also you are beloved by us. Let the members love one another, but live all under the Head.
Augustine of Hippoon John 3:29AD 430
But what of that resurrection of the body? For these who hear and live, whence live, except by hearing? For "the friend of the Bridegroom standeth and heareth Him, and rejoiceth greatly because of the Bridegroom's voice:" not because of his own voice; that is to say, they hear and live by partaking, not by coming into being; and all that hear live, because all that obey live.
Cyril of Alexandriaon John 3:29AD 444
The discourse again took its rise from likeness to our affairs, but leads us to the knowledge of subtle thoughts. For types of things spiritual are those which endure the touch of the hand, and the grossness of corporeal examples introduceth oftentimes a most accurate proof of things spiritual. Christ then, says he, is the Bridegroom and ruler of the assembly, I the bidder to the supper and conducter of the bride, having as my chiefest joy and illustrious dignity, to be only enrolled among His friends, and to hear the Voice of Him That feasteth. I have therefore even now that that I long for, and my dearest wish is fulfilled. For not only did I preach that Christ would come, but Him already present have I seen, and His very Voice do I lay up in my ears. But ye, most wise disciples, seeing the human nature that is betrothed to Christ, going to Him, and beholding the nature which was cut off and a run-away from its love to Him attaining to spiritual union through holy Baptism, grieve not, saith he, that it befits not me, but rather runs very gladly to the spiritual Bridegroom (for this were in truth just and more fitting). For He That hath the bride is the Bridegroom; that is, seek not in me the crown of the Bridegroom, not for me does the Psalmist rejoice, saying, Hearken, O daughter, and consider, and incline thine ear; forget also thine own people and thy father's house, for the King hath desired thy beauty: nor seeking my chamber doth the bride say, Tell me, O Thou Whom my soul loveth, where Thou feedest, where Thou makest Thy flock to rest at noon: she has the Bridegroom from Heaven. But I will rejoice, having surpassed the honour becoming a bondman, in the title and reality of friendship.

I deem then that the meaning of the passage, has been full well interpreted: and having already sufficiently explained the spiritual marriage, I think it tedious to write any more about it.
Gregory the Dialogiston John 3:29AD 604
"Whose sandal strap I am not worthy to untie." The custom among the ancients was that if someone did not wish to take as wife the one who was suited to him, he who came as bridegroom by right of kinship to her would untie his sandal. What then did Christ appear as among men, if not the bridegroom of holy Church? Of whom the same John also says: "He who has the bride is the bridegroom." But because men thought John was the Christ, which the same John denies, he rightly declares himself unworthy to untie the strap of his sandal. As if he openly said: I am unable to uncover the footsteps of our Redeemer, because I do not undeservedly usurp for myself the name of bridegroom.
Gregory the Dialogiston John 3:29AD 604
Those who thought John was Christ believed the Church to be his bride. But he said: "He who has the bride is the bridegroom." As if to say: I am not the bridegroom, but the friend of the bridegroom. Nor did he declare that he rejoiced because of his own voice, but in the voice of the bridegroom, because he did not rejoice in his heart because he was humbly heard by the people when he spoke, but because he himself heard the voice of truth within so that he might speak outwardly. He rightly says his joy was fulfilled, because whoever rejoices in his own voice does not have full joy.
Bedeon John 3:29AD 735
The one who has the bride is the bridegroom. By the bride he means the church gathered from among all nations.… It is a virgin pure of heart, perfect in love, bound to him in the bond of peace, in chastity of body and soul and in the unity of the Catholic faith. For it is useless for her to be a virgin in body without retaining the purity of the Catholic faith. Our Lord therefore committed his bride to his friends who are the preachers of the true gospel. Therefore, John says, "The friend of the bridegroom who stands and hears him rejoices greatly because of the bridegroom's voice." The friend is able to stand and hear him because he remains in the true faith and preaches what he believes.

Bedeon John 3:29AD 735
Who art thou then, since thou art not the Christ, and who is He to Whom thou bearest witness? John replies, He is the Bridegroom; I am the friend of the Bridegroom, sent to prepare the Bride for His approach: He that hath the Bride, is the Bridegroom. By the Bride he means the Church, gathered from amongst all nations; a Virgin in purity of heart, in perfection of love, in the bond of peace, in chastity of mind and body; in the unity of the Catholic faith; for in vain is she a virgin in body, who continueth not a virgin in mind. This Bride hath Christ joined unto Himself in marriage, and redeemed with the price of His own Blood.

His Bride therefore our Lord committed to His friend, i. e. the order of preachers, who should be jealous of her, not for themselves, but for Christ; The friend of the Bridegroom which standeth and heareth Him, rejoiceth greatly because of the Bridegroom's voice.

He rejoiceth at hearing the Bridegroom's voice, who knows that he should not rejoice in his own wisdom, but in the wisdom which God giveth him. Whoever in his good works seeketh not his own glory, or praise, or earthly gain, but hath his affections set on heavenly things; this man is the friend of the Bridegroom.
Theophylact of Ohridon John 3:29AD 1107
Christ is the spouse of every soul; the wedlock, wherein they are joined, is baptism; the place of that wedlock is the Church; the pledge of it, remission of sins, and the fellowship of the Holy Ghost; the consummation, eternal life; which those who are worthy shall receive. Christ alone is the Bridegroom: all other teachers are but the friends of the Bridegroom, as was the forerunner. The Lord is the giver of good; the rest are the despisers of His gifts.

For which cause I rejoice now, that all men follow Him. For had the bride, i. e. the people, not come forth to meet the Bridegroom, then I, as the friend of the Bridegroom, should have grieved,
Theophylact of Ohridon John 3:29AD 1107
If the Bride, that is, the people, were not coming to this Bridegroom, then I, the friend of the bridegroom, would grieve; but now that this has happened, I rejoice greatly, for I see that the Bridegroom — Christ — calls out to the bride — the people — and teaches them.
Not without purpose did he say "standing," but by this he shows that his work is finished and he stands already without activity, and that he finally needs to stand and only listen to the teaching of Christ and His conversation with the bride.
"My joy," he says, "has been fulfilled in the Bridegroom." The task entrusted to me as the friend of the bridegroom, I see, has succeeded.
So, the Lord is the bridegroom of every soul; the bridal chamber in which the union takes place is the place of baptism, that is, the church; He gives the bride a pledge — the forgiveness of sins, the communion of the Holy Spirit, and the rest in the age to come, when He will lead those who are worthy into better and higher mysteries. Note, then, that the bridegroom is none other than Christ alone, while all teachers are friends of the bridegroom, as was the Forerunner. For the giver of blessings is none other than the Lord alone; all the rest are mediators and ministers of the blessings bestowed by the Lord.
Thomas Aquinason John 3:29AD 1274
He shows how John is related to his own office when he says: It is the groom who has the bride. First, he gives a simile. Secondly, he applies it to his own situation. With respect to the first he does two things. First, he gives a simile which applies to Christ; and secondly, to himself.

As to the first, we should note that on the human level it is the groom who regulates, governs and has the bride. Hence he says, It is the groom who has the bride. Now the groom is Christ: "Like a bridegroom coming out of his bridal chamber" (Ps 18:6). His bride is the Church, which is joined to him by faith: "I will espouse you to myself in faith" (Hos 2:20). In keeping with this figure, Zipporah said to Moses: "You are a spouse of blood to me" (Ex 4:25). We read of the marriage: "The marriage of the Lamb has come" (Rv 19:7). So, because Christ is the groom, he has the bride, that is, the Church; but my part is only to rejoice in the fact that he has the bride.

Consequently he says, The groom's friend waits there and listens to him, rejoicing at hearing his voice. Although John had said earlier that he was not worthy to unfasten the strap of Jesus' sandal, he here calls himself the friend of Jesus in order to bring out the faithfulness of his love for Christ. For a servant does not act in the spirit of love in regard to the things that pertain to his master, but in a spirit of servitude; while a friend, on the other hand, seeks his friend's interests out of love and faithfulness. Hence a faithful servant is like a friend to his master: "If you have a faithful servant, treat him like yourself" (Sir 33:31). Indeed, it is proof of a servant's faithfulness when he rejoices in the prosperity of his master, and when he obtains various goods, not for himself, but for his master. And so because John did not keep the bride entrusted to his care for himself, but for the groom, we can see that he was a faithful servant and a friend of the groom. It is to suggest this that he calls himself the groom's friend.

Those who are friends of the truth should act in the same way, not turning the bride entrusted to their care to their own advantage and glory, but treating her honorably for the honor and glory of the groom; otherwise they would not be friends of the groom but adulterers. This is why Gregory says that a servant who is sent by the groom with gifts for the bride is guilty of adulterous thoughts if he himself desires to please the bride. This is not what the Apostle did: "I espoused you to one husband in order to present you to Christ as a chaste virgin" (2 Cor 11:2). And John did the same, because he did not keep the bride, i.e., the faithful, for himself, but brought them to the groom, that is, to Christ.

And so by saying, the groom's friend, he suggests the faithfulness of his love. Further, he suggests his constancy when he says, waits, firm in friendship and faithfulness, not extolling himself above what he really is: "I will stand my watch" (Hb 2:1); "Be steadfast and unchanging" (1 Cor 15:58); "A faithful friend, if he is constant, is like another self" (Sir 6:11).

He suggests his attention when he says, and listens to him, i.e., attentively considers the way in which the groom is united to the bride. For according to Chrysostom, these words explain the manner of this marriage, for it is accomplished through faith, and "faith comes through hearing" (Rom 10:17). Or, he listens to him, i.e., reverently obeys him, by caring for the bride according to the commands of the groom: "I will listen to him as my master," as is said in Isaiah (50:4). This is in opposition to those evil prelates who do not follow Christ's command in governing the Church.

Likewise, he hints at his spiritual joy when he says, rejoicing at hearing his voice, that is, when the groom talks to his bride. And he says, rejoicing (literally, "rejoicing with joy"), to show the truth and perfection of his joy. For one whose rejoicing is not over the good, does not rejoice with true joy. And so, if it made me sad that Christ, who is the true groom, preaches to the bride, i.e., the Church, I would not be a friend of the groom; but I am not sad.

Therefore in this case my joy is complete, namely, in seeing what I have so long desired, that is, the groom speaking to his bride. Or, my joy is complete, i.e., brought to its perfect and due measure, when the bride is united to the groom, because I now have my grace and I have completed my work: "I will rejoice in the Lord, and I will take joy in God, my Jesus" (Hb 3:18).
