Jerome
Catena Aurea · Matthäusevangelium 9
Then came to him the disciples of John, saying, Why do we and the Pharisees fast oft, but thy disciples fast not? And Jesus said unto them, Can the children of the bridechamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast. No man putteth a piece of new cloth unto an old garment, for that which is put in to fill it up taketh from the garment, and the rent is made worse. Neither do men put new wine into old bottles; else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.
Christ is the Bridegroom and the Church the Bride. Of this spiritual union the Apostles were born; they cannot mourn so long as they see the Bridegroom in the chamber with the Bride. But when the nuptials are past, and the time of passion and resurrection is come, then shall the children of the Bridegroom fast. The days shall come when the bridegroom shall be taken from them, and then shall they fast.
