Lastly, God rested from the works of the world not from holy works, for His working is constant and everlasting; as the Son says, My Father worketh until now, and I work; (John 5:17.) that after the likeness of God our worldly, not our religious, works should cease. Accordingly our Lord pointedly answered him, as it follows, Thou hypocrite, doth not each one of you on the sabbath-day loose his ox or his ass? &c.

Or the fig tree represents the synagogue; afterwards in the infirm woman there follows as it were a figure of the Church, which having fulfilled the measure of the law and the resurrection, and now raised up on high in that eternal resting place, can no more experience the frailty of our weak inclinations. Nor could this woman be healed except she had fulfilled the law and grace. For in ten sentences is contained the perfection of the law, and in the number eight the fulness of the resurrection.

Now this miracle is a sign of the coming sabbath, when every one who has fulfilled the law and grace, shall by the mercy of God put off the toils of this weak body. But why did He not mention any more animals, save to show that the time would come when the Jewish and Gentile nations should quench their bodily thirst, and this world's heat in the fulness of the fountain of the Lord, and so through the calling forth of two nations, the Church should be saved.

In another place, a grain of mustard seed is introduced where it is compared to faith. If then the mustard seed is the kingdom of God, and faith is as the grain of mustard seed; faith is truly the kingdom of heaven, which is within us. (Luke 17:21.) A grain of mustard seed is indeed a mean and trifling thing, but as soon as it is crushed, it pours forth its power. And faith at first seems simple, but when it is buffeted by adversity, pours forth the grace of its virtue. The martyrs are grains of mustard seed. They have about them the sweet odour of faith, but it is hidden. Persecution comes; they are smitten by the sword; and to the farthest boundaries of the whole world they have scattered the seeds of their martyrdom. The Lord Himself also is a grain of mustard seed; He wished to be bruised that we might see that we are a sweet savour of Christ. (2 Cor. 2:15.) He wishes to be sown as a grain of mustard seed, which when a man takes he puts it into his garden. For Christ was taken and buried in a garden, where also He rose again and became a tree, as it follows, And it waxed into a great tree. For our Lord is a grain when He is buried in the earth, a tree when He is lifted up into the heaven. He is also a tree overshadowing the world, as it follows, And the fowls of the air rested in his branches; that is, the heavenly powers and they whoever (for their spiritual deeds) have been thought worthy to fly forth. Peter is a branch, Paul is a branch, into whose arms, by certain hidden ways of disputation, we who were a far off now fly, having taken up the wings of the virtues. Sow then Christ in thy garden; a garden is truly a place full of flowers, wherein the grace of thy work may blossom, and the manifold odour of thy different virtues be breathed forth. Wherever is the fruit of the seed, there is Christ.

Many think Christ is the leaven, for leaven which is made from meal, excels its kind in strength, not in appearance. So also Christ (according to the Fathers) shone forth above others equal in body, but unapproachable in excellence. The Holy Church therefore represents the type of the woman, of whom it is added, Which a woman, took and hid in three measures (sata) of meal, till the whole was leavened.

But we are the meal of the woman which hide the Lord Jesus in the secrets of our hearts, until the heat of heavenly wisdom penetrates our innermost recesses. And since He says it was hid in three measures, it seems fitting that we should believe the Son of God to have been hid in the Law, veiled in the Prophets, manifested in the preaching of the Gospel. Here however I am invited to proceed farther, because our Lord Himself has taught us, that the leaven is the spiritual teaching of the Church. Now the Church sanctifies with its spiritual leaven the man who is renewed in body, soul, and spirit, seeing that these three are united in a certain equal measure of desire, and there breathes forth a complete harmony of the will. If then in this life the three measures abide in the same person until they are leavened and become one, there will be hereafter an incorruptible communion with them that love Christ.

He turned to the Gentiles from the careless scorn of the rich. He invites both good and evil to enter in order to strengthen the good and change the disposition of the wicked for the better. The saying that was read today is fulfilled, “Then wolves and lambs will feed together.” He summons the poor, the maimed and the blind. By this, he shows us either that handicaps do not exclude us from the kingdom of heaven and whoever lacks the enticements of sinning rarely offends, or that the Lord’s mercy forgives the weakness of sinners. Whoever glories in the Lord glories as one redeemed from reproach not by works but by faith.He sends them into the highways, because wisdom sings aloud in passages. He sends them to the streets, because he sent them to sinners, so that they should come from the broad paths to the narrow way that leads to life. He sends them to the highways and hedges. They, who are not busied with any desires for present things, hurry to the future on the path of good will. Like a hedge that separates the wild from the cultivated and wards off the attacks of wild beasts, they can distinguish between good and evil and extend a rampart of faith against the temptations of spiritual wickedness.

Thus it is that the worn out soldier is appointed to serve degraded offices, as he who intent upon things below buys for himself earthly possessions, can not enter into the kingdom of heaven. Our Lord says, Sell all that thou hast, and follow me.
It follows, And another said, I have bought five yoke of oxen, and I go to prove them.

Or marriage is not blamed; but purity is held up to greater honour, since the unmarried woman careth for the things of the Lord, that she may be holy in body and spirit, but she that is married careth for the things of the world. (1 Cor. 7:34.)

Or let us suppose that three classes of men are excluded from partaking of that supper, Gentiles, Jews, Heretics. The Jews by their fleshly service impose upon themselves the yoke of the law, for the five yoke are the yoke of the Ten Commandments, of which it is said, And he declared unto you his covenant, which he commanded you to perform, even ten commandments; and he wrote them upon two tables of stone. (Deut. 4:13.) That is, the commands of the Decalogue. Or the five yoke are the five books of the old law. But heresy indeed, like Eve with a woman's obstinacy, tries the affection of faith. And the Apostle says that we must flee from covetousness, lest entangled in the customs of the Gentiles we be unable to come to the kingdom of Christ. (Eph. 5:3, Col. 3:5, Heb. 13:5, 1 Tim. 6:11.) Therefore both he who has bought a farm is a stranger to the kingdom, and he who has chosen the yoke of the law rather than the gift of grace, and he also who excuses himself because he has married a wife.
It follows, And the servant returned, and told these things to his Lord.

He invites the poor, the weak, and the blind, to show that weakness of body shuts out no one from the kingdom of heaven, and that he is guilty of fewer sins who lacks the incitement to sin; or that the infirmities of sin are forgiven through the mercy of God. Therefore he sends to the streets, that from the broader ways they may come to the narrow way.
Because then the proud refuse to come, the poor (Greg. Hom. 36.) are chosen, since they are called weak and poor who are weak in their own judgment of themselves, for there are poor, and yet as it were strong, who though lying in poverty are proud; the blind are they who have no brightness of understanding; the lame are they who have walked not uprightly in their works. But since the faults of these are expressed in the weakness of their members, as those were sinners who when bidden refused to come, so also are these who are invited and come; but the proud sinners are rejected, the humble are chosen. God then chooses those whom the world despises, because for the most part the very act of contempt recals a man to himself. And men so much the sooner hear the voice of God, as they have nothing in this world to take pleasure in. When then the Lord calls certain from the streets and lanes to supper, He denotes that people who had learnt to observe in the city the constant practice of the law. But the multitude who believed of the people of Israel did not fill the places of the upper feast room. Hence it follows, And the servant said, Lord, it is done as thou hast commanded, and yet there is room. For already had great numbers of the Jews entered, but yet there was room in the kingdom for the abundance of the Gentiles to be received. Therefore it is added, And the Lord said unto the servant, Go out into the highways and hedges, and compel them to come in, that my house may be filled. When He commanded His guests to be collected from the wayside and the hedges, He sought for a rural people, that is, the Gentiles.

Or, He sends to the highways and about the hedges, because they are fit for the kingdom of God, who, not absorbed in the desire for present goods, are hastening on to the future, set in a certain fixed path of good will. And who like a hedge which separates the cultivated ground from the uncultivated, and keeps off the incursion of the cattle, know how to distinguish good and evil, and to hold up the shield of faith against the temptations of spiritual wickedness.

The woman did not idly rejoice to find her coin. The coin, having the image of the emperor, is not ordinary. The image of the King is the register of the church. We are sheep. Let us pray that he would be pleased to place us beside the water of rest. We are sheep. Let us seek pastures. We are coins. Let us have a price. We are sons. Let us hurry to the Father. Let us not fear because we have squandered the inheritance of spiritual dignity that we received on earthly pleasures. Since the Father conferred on the Son the treasure that he had, the wealth of faith is never made void. Although he has given all, he possesses all and does not lose what he has bestowed. Do not fear that perhaps he will not receive you, for the Lord has no pleasure in the destruction of the living. Already meeting you on the way, he falls on your neck, “for the Lord sets the fallen right.” He will give you a kiss, that is, the pledge of piety and love. He will order the robe, ring and the shoes to be brought. You still dread harshness, but he has restored dignity. You are terrified of punishment, but he offers a kiss. You fear reproach, but he prepares a banquet. Let us now discuss the actual parable.
