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.
All Commentaries on John 3:29 Go To John 3
Cyril of Alexandria
AD 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.
