Catena Aurea · Markusevangelium 2
And the disciples of John and of the Pharisees used to fast: and they come and say unto him, Why do the disciples of John and of the Pharisees fast, but thy disciples fast not? And Jesus said unto them, Can the children of the bridechamber fast, while the bridegroom is with them? as long as they have the bridegroom with them, they cannot fast. But the days will come, when the bridegroom shall be taken away from them, and then shall they fast in those days. No man also seweth a piece of new cloth on an old garment: else the new piece that filled it up taketh away from the old, and the rent is made worse. And no man putteth new wine into old bottles: else the new wine doth burst the bottles, and the wine is spilled, and the bottles will be marred: but new wine must be put into new bottles.
(de Con. Evan. ii. 27) But it may be thought that He added Pharisees, because they joined with the disciples of John in saying this to the Lord, whilst Matthew relates that the disciples of John alone said it: but the words which follow rather shew that those who said it spoke not of themselves, but of others. For it goes on, And they come and say unto him, Why do the disciples, &c. For these words shew, that the guests who were there came to Jesus, and had said this same thing to the disciples, so that in the words which he uses, they came, he speaks not of those same persons, of whom he had said, And the disciples of John and the Pharisees were fasting. But as they were fasting, those persons who remembered it, come to him. Matthew then says this, And there came to him the disciples of John, saying, because the Apostles also were there, and all eagerly, as each could, objected these things.
