He spoke also this parable;
A certain man had a fig tree planted in his vineyard; and he came and sought fruit thereon, and found none.

Ambrose of Milan
AD 397
There was avineyard of the Lord of hosts, which He gave for a spoil to the Gentiles. And the comparison of the fig tree to the synagogue is well chosen, because as that tree abounds with wide and spreading foliage, and deceives the hopes of its possessor with the vain expectation of promised fruit, so also in the synagogue, while its teachers are unfruitful in good works, yet magnify themselves with words as with abundant leaves, the empty shadow of the law stretches far and wide. This tree also is the only one which puts forth fruit in place of flowers. And the fruit falls, that other fruit may succeed; yet some few of the former remain, and donot fall. For the first people of the synagogue fell off as a useless fruit, in order that out of the fruitfulness of the old religion might arise the new people of the Church; yet they who were the first out of Israel whom a branch of a stronger nature bore, under the shadow of the law and the cross, in the bosom of both, stained with a double juice after the example of aripening fig, surpassed all others in the grace of most excellent fruits; to whom it is said, You shall sit upon twelve thrones. Some however think the fig tree to be a figure not of the synagogue, but of wickedness and treachery; y et these differ in nothing from what has gone before, except that they choose the genus instead of the species.
But our Lord sought, not because He was ignorant that the fig tree had no fruit, but that He might show in a figure that the synagogue ought by this time to have fruit. Lastly, from what follows, He teaches that He Himself came not before the time who came after three years. For so it is said, Then said he to the dresser of the vineyard, Behold, these three years I come seeking fruit on this fig tree, and find none. He came to Abraham, He came to Moses, He came to Mary, that is, He came in the seal of the covenant, He came in the law, He came in the body. We recognise His coming by His gifts; at one time purification, at another sanctification, at another justification. Circumcision purified, the law sanctified, grace justified. The Jewish people then could not be purified because they had not the circumcision of the heart, but of the body; nor be sanctified, because ignorant of the meaning of the law, they followed carnal things rather than spiritual; nor justified, because not working repentance for the their offences, they knew nothing of grace. Rightly then was there no fruit found in the synagogue, and consequently it is ordered to be cut down; for it follows, Cut it down, why cumbers it the ground? But the merciful dresser, perhaps meaning him on whom the Church is founded, foreseeing that another would be sent to the Gentiles, but he himself to them who were of the circumcision, piously intercedes that it may not be cut off; trusting tohis calling, that the Jewish people also might be saved through the Church. Hence it follows, And he answering said to him, Lord, let it alone this year also. He soon perceived hardness of bears and pride to be the causes of the barrenness of the Jews. He knew therefore how to discipline, who knew how to censure faults. Therefore adds He, till I shall dig about it. He promises that the hardness of their hearts shall be dug about by the Apostles' spades, lest aheap of earth cover up and obscure the root of wisdom. And He adds, and dung it, that is, bythe grace of humility, by which even the fig is thought to become fruitful toward the Gospel of Christ. Hence He adds, And if it bear fruit, well, that is, it shall be well, but if not, then after that you shall cut it down.
