14 And Jesus answered and said unto it, No man eat fruit of thee hereafter for ever. And his disciples heard it.
[AD 407] John Chrysostom on Mark 11:11-14
(in Matt. Hom. 67) How is it that He was hungry in the morning, as Matthew says, if it were not that by an economy He permitted it to His flesh? There follows, And seeing a fig tree afar off having leaves, he came, if haply he might find any thing thereon. Now it is evident that this expresses a conjecture of the disciples, who thought that it was for this reason that Christ came to the fig tree, and that it was cursed, because He found no fruit upon it. For it goes on: And when he came to it, he found nothing but leaves; for the time of figs was not yet. And Jesus answered and said unto it, No man eat fruit of thee hereafter for ever. He therefore curses the fig tree for His disciples sake, that they might have faith in Him. For He every where distributed blessings, and punished no one, yet at the same time, it was right to give them a proof of His chastising power, that they might learn that He could even cause the persecuting Jews to wither away; He was however unwilling to give this proof on men, wherefore He showed them on a plant a sign of His power of punishing. This proves that He came to the fig tree principally for this reason, and not on account of His hunger, for who is so silly as to suppose that in the morning He felt so greatly the pains of hunger, or what prevented the Lord from eating before He left Bethany? Nor can it be said that the sight of the figs excited His appetite to hunger, for it was not the season of figs; and if He were hungry, why did He not seek food elsewhere, rather than from a fig-tree which could not yield fruit before its time? What punishment also did a fig tree deserve for not having fruit before its time? From all this then we may infer, that He wished to show His power, that their minds might not be broken by His Passion.

(non occ.) We may also say, in another sense, that the Lord sought for fruit on the fig tree before its time, and not finding it, cursed it, because all who fulfil the commandments of the Law, are said to bear fruit in their own time, as, for instance, that commandment, Thou shalt not commit adultery; but he who not only abstains from adultery but remains a virgin, which is a greater thing, excels them in virtue. But the Lord exacts from the perfect not only the observance of virtue, but also that they bear fruit over and above the commandments.

[AD 735] Bede on Mark 11:11-14
(ubi sup.) As the time of His Passion approached, the Lord wished to approach to the place of His Passion, in order to intimate that He underwent death of His own accord: wherefore it is said, And Jesus entered into Jerusalem, and into the temple. And by His going to the temple on first entering the city, He shows us beforehand a form of religion, which we are to follow, that if by chance we enter a place, where there is a house of prayer, we should first turn aside to it. We should also understand from this, that such was the poverty of the Lord, and so far was He from flattering man, that in so large a city, He found no one to be His host, no abiding place, but lived in a small country place with Lazarus and his sisters; for Bethany is a hamlet of the Jews. Wherefore there follows: And when he had looked round about upon all things, (that is, to see whether any one would take Him in,) and now the eventide was come, he went out into Bethany with the twelve. Nor did He do this once only, but during all the five days, from the time that He came to Jerusalem, to the day of His Passion, He used always to do the same thing; during the day He taught in the temple, but at night, He went out and dwelt in the mount of Olives. It goes on, And on the morrow, when they were come from Bethany, he was hungry.

(ubi sup.) Farther, He looks round about upon the hearts of all, and when in those who opposed the truth, He found no place to lay His head, He retires to the faithful, and takes up His abode with those who obey Him. For Bethany means the house of obedience.

(ubi sup.) Just in the same way as He speaks parables, so also His deeds are parables; therefore He comes hungry to seek fruit off the fig tree, and though He knew the time of figs was not yet, He condemns it to perpetual barrenness, that He might show that the Jewish people could not be saved through the leaves, that is, the words of righteousness which it had, without fruit, that is, good works, but should be cut down and cast into the fire. Hungering therefore, that is, desiring the salvation of mankind, He saw the fig tree, which is, the Jewish people, having leaves, or, the words of the Law and the Prophets, and He sought upon it the fruit of good works, by teaching them, by rebuking them, by working miracles, and He found it not, and therefore condemned it. Do thou too, unless thou wouldest be condemned by Christ in the judgment, beware of being a barren tree, but rather offer to Christ the fruit of piety which He requires.

[AD 1107] Theophylact of Ohrid on Mark 11:11-14
Wishing to show His disciples that if He chose He could in a moment exterminate those who were about to crucify Him. In a mystical sense, however, the Lord entered into the temple, but came out of it again, to show that He left it desolate, and open to the spoiler.

[AD 1274] Pseudo-Jerome on Mark 11:11-14
He went in the morning to the Jews, and visits us in the eventide of the world.

[AD 373] Ephrem the Syrian on Mark 11:14
The owner of the fig tree did not obey the law but spurned it. Our Lord came and found that there was [nothing] left on it, so he cursed it, lest its owner eat from it again, since he had left [nothing] for the orphan and widows.… He cursed the fig tree and it shriveled up to show them the power of his divinity, so that by means of [this] action near at hand which they could see, they might believe that which was to come. Because [Jerusalem] had not accepted the law, he cursed [the fig tree], so that there might no longer be fruit on it, according to its law.… He sought fruit from the fig tree at an inopportune time, that it might be a symbol of one who had deceitfully withheld the fruits of the law at the opportune time. For, if he had sought fruit from it at the opportune time, no one would have known that there was a figurative meaning embedded here. Instead of the fig tree, therefore, he showed that it was Jerusalem that he was reproaching, for he had sought love in her, but she had despised the fruit of repentance.… Why, therefore, did he who was good and gentle, who everywhere revealed great things out of little things, and completion out of imperfection, why did he command the fig tree to dry up? For he healed the sufferings of everyone, changed water to wine, made an abundance from a little bread, opened the eyes of the blind, cleansed lepers and raised the dead to life. But this fig tree alone did he cause to wither. It was because the time of his suffering was near, and, lest it be thought that he was captured because he was unable to free himself, he cursed the fig tree, that it might be a sign for his friends, and a miracle for his enemies. Thus, the disciples would be strengthened by his word, and others would be amazed at his power. Because he did all things well, and [the time] for him to suffer was near, it might be thought, as indeed it was, that he was captured because he possessed no power. He showed in advance, therefore, by means of a living plant which he caused to wither, that he would have been able to destroy his crucifiers with a word.

[AD 386] Cyril of Jerusalem on Mark 11:14
Remember at the time of the sin of Adam and Eve they clothed themselves—with what? Fig leaves. That was their first act after the fall. So now Jesus is making the same figure of the fig tree the very last of his wondrous signs. Just as he was headed toward the cross, he cursed the fig tree—not every fig tree, but that one alone for its symbolic significance—saying: “May no one ever eat fruit of you again.” In this way the curse laid upon Adam and Eve was being reversed. For they had clothed themselves with fig leaves.
