Theophylact of Ohrid
Catena Aurea · Johannesevangelium 3
John answered and said, A man can receive nothing, except it be given him from heaven. Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him. 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. He must increase, but I must decrease.
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 HolyGhost; 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.
