1 The lesson of the Holy Gospel which has just been read, has given us an alarming warning, lest we have leaves only, and have no fruit. That is, in few words, lest words be present and deeds be wanting. Very terrible! Who does not fear when in this lesson he sees with the eyes of the heart the withered tree, withered at that word being spoken to it, “Let no fruit grow on you henceforward for ever”? Let the fear work amendment, and the amendment bring forth fruit. For without doubt, the Lord Christ foresaw that a certain tree would deservedly become withered, because it would have leaves, and would have no fruit.
That tree is the synagogue, not that which was called, but that which was reprobate. For out of it also was called the people of God, who in sincerity and truth waited in the Prophets for the salvation of God, Jesus Christ. And forasmuch as it waited in faith, it was thought worthy to know Him when He was present. For out of it came the Apostles, out of it came the whole multitude of those who went before the ass of the Lord, and said, “Hosanna to the Son of David, blessed is He that comes in the Name of the Lord.” There was a great company then of believing Jews, a great company of those who believed in Christ before He shed His Blood for them.
For it was not in vain that the Lord Himself had come to none “but to the lost sheep of the house of Israel.” But in others, after He was crucified, and was now exalted into heaven, He found the fruit of repentance; and these He did not make to wither, but cultivated them in His field, and watered them with His word. Of this number were those four thousand Jews who believed, after that the disciples and those who were with them, filled with the Holy Ghost, spoke with the tongues of all nations, and in that diversity of tongues announced in a way beforehand, that the Church should be throughout all nations.
They believed at that time, and “they were the lost sheep of the house of Israel;” but because “the Son of Man had come to seek and to save that which was lost,” He found these also. But they lay hid here and there among thorns, as though wasted and dispersed by the wolves; and because they lay hid among thorns, He did not come to find them, save when torn by the thorns of His Passion; yet come He did, He found, He redeemed them. They had slain, not Him so much, as themselves.
They were saved by Him who was slain for them. For, as the Apostles spoke, they were pricked; they were pricked in conscience, who had pricked Him with the spear; and being pricked they sought for counsel, received it when it was given, repented, found grace, and believing drunk that Blood which in their fury they had shed. But they who have remained in this bad and barren race, even unto this day, and shall remain unto the end, were figured in that tree. You come to them at this day, and find with them all the writings of the Prophets.
But these are but leaves; Christ is an hungred, and He seeks for fruit; but finds no fruit among them, because He does not find Himself among them. For He has no fruit, who has not Christ. And he has not Christ, who holds not to Christ's unity, who has not charity. And so by this chain he has no fruit who has not charity. Hear the Apostle, “Now the fruit of the Spirit is charity;” so setting forth the praise of this cluster, that is, of this fruit; “The fruit of the Spirit,” he says, “is charity, joy, peace, long-suffering.” Do not wonder at what follows, when charity leads the way.
