He that has the bride is the bridegroom: but the friend of the bridegroom, who stands and hears him, rejoices greatly because of the bridegroom's voice: this my joy therefore is fulfilled.

John Chrysostom
AD 407
But how does 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 says 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 calls 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, says 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 has come to pass, and the bride knows the Bridegroom, and you are witnesses of it when you 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.
3. But what means, He which stands and hears Him rejoices 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 says, Faith comes by hearing, and hearing by the word of God. Romans 10:17 At this 'Voice,' says he, I rejoice. And not without a cause does he put who stands, 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 says,
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. Therefore he continues,
