John Chrysostom
Catena Aurea · Matthäusevangelium 21
And he left them, and went out of the city into Bethany; and he lodged there. Now in the morning as he returned into the city, he hungered. And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the fig tree withered away. And when the disciples saw it, they marvelled, saying, How soon is the fig tree withered away! Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done. And all things, whatsoever ye shall ask in prayer believing, ye shall receive.
This was only a supposition of the disciples that it was cursed because it had not fruit; for another Evangelist says that it was not yet the season. Why then was it cursed? For the disciples’ sake, that they might learn that He had power to wither up those who crucified Him. And He worked this miracle in that which of all plants is the most juicy, that the greatness of the miracle might be more apparent. And when aught of this kind is done to brutes or vegetables, ask not whether the fig were with justice withered up, seeing it was not the season for its fruit; for to enquire thus were extreme madness, for in such creatures there can be neither fault nor punishment; but consider the miracle, and admire the Worker of it.
