Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 2:18-22

“He also calls Himself a bridegroom, not only as betrothing to Himself virgin minds, but because the time of His first coming is not a time of sorrow, nor of sadness to believers, neither does it bring with it toil, but rest. For it is without any works of the law, giving rest by baptism, by which we easily obtain salvation without toil. But the sons of the nuptials or of the Bridegroom are the Apostles; because they, by the grace of God, are made worthy of every heavenly blessing, by the grace of God, and partakers of every joy.”
