Mark 2:20

(Vict. Ant. e Cat. in Marc.) But intercourse with Him, He says, is far removed from all sorrow, when He adds, As long as they have the bridegroom with them, they cannot fast. He is sad, from whom some good is far removed; but he who has it present with him rejoices, and is not sad. But that He might destroy their elation of heart, and show that He intended not His own disciples to be licentious, He adds, But the days will come when the bridegroom shall be taken, &c. as if He said, The time will come, when they will show their firmness; for when the Bridegroom shall be taken from them, they will fast as longing for His coming, and in order to unite to Him their spirits, cleansed by bodily suffering. He shows also that there is no necessity for His disciples to fast, as having present with them the Bridegroom of human nature, Who every where executes the words of God, and Who gives the seed of life. The sons of the Bridegroom also cannot, because they are infants, be entirely conformed to their Father, the Bridegroom, Who, considering their infancy, deigns to allow them not to fast: but when the Bridegroom is gone, they will fast, through desire of Him; when they have been made perfect, they will be united to the Bridegroom in marriage, and will always feast at the king's banquet.

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. We must also understand, that every man whose works are good is the son of the Bridegroom; he has the Bridegroom with him, even Christ, and fasts not, that is, does no works of repentance, because he does not sin: but when the Bridegroom is taken away by the man's falling into sin, then he fasts and is penitent, that he may cure his sin.
