Theophylact of Ohrid — as excerpted in the Catena Aurea on John 3:27-30

“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.”
