And the Lord said,
If you had faith as a grain of mustard seed, you could say unto this sycamine tree, Be plucked up by the root, and be planted in the sea; and it would obey you.

If ye had faith. "This indeed," says S. Chrysostom, "is small in quantity but great in power. He means that the least portion of faith can do great things." And Bede, "Perfect faith is a grain of mustard seed: in appearance it is small, in the heart it is fervent."
You would say unto this sycamine tree (a mulberry tree (moro) close at hand, to which Christ pointed). Be thou rooted up and be thou east into the sea, and it would have obeyed you.—For mulberry tree, Matthew 17:20 has mountain. Christ therefore said both. It is called the mulberry tree allegorically, as if μώζος (foolish); that is by antithesis, because it is the wisest of trees; not putting forth its leaves till the frost is over, lest they should be cut off. The mulberry signifies the gospel of the cross of Christ, which to the Gentiles appears foolishness, but to the faithful is "the power of God and the wisdom of God," 1 Corinthians 1:24. Hence S. Augustine (Lib. II, Quæst. Evan.: quæst39): "Let those servants speak through the grain of mustard seed, to this mulberry tree; that Isaiah , to the gospel of the cross of Christ through the blood-coloured apples hanging like wounds on that tree which is to give food to the nations. Let them say that it is rooted up by the unbelief of the Jews, and transferred to the sea of the Gentiles and planted there, for by this home service they will minister to the hungering and thirsting Lord." So too Bede. "The mulberry tree," he says, "by the blood colour of the fruit and shoots, is the gospel of the cross of Christ, which, through the faith of the Apostles, when it was held as it were in the stem of its kind, was rooted up from the Jews, and planted in the sea of the Gentiles." The Gloss adds, "The leaves of the mulberry, offered to the serpent, bring death upon him, as the word of the cross destroys all hurtful and venomous things of the soul." On the other hand, SS. Ambrose and Chrysostom and the Gloss understand by the mulberry tree, the devil, whom the faith of Christ casts out and sends into hell. "The fruit of the mulberry, tree," says S. Ambrose, "is firstly white, when in flower, when fully blown red, and when ripe it becomes black. The devil also, from the white flower of his angelic nature and power, when cast out by his reddening wickedness, grew horrible from the foul odour of sin. Behold Christ saying to the mulberry tree, "Be thou rooted up and cast into the sea;" when He cast the Legion out of the Prayer of Manasseh , He permitted them to enter into the swine which, being driven by the spirit of the devils, cast themselves into the sea."
Hear also S. Chrysostom in the Catena: "As the mulberry feeds worms (silkworms) which spin silk from its leaves, so does the devil, from thoughts springing from those leaves, nourish in us an undying worm; but faith has power to root this tree out of our souls, and to plunge it into hell."
Lastly, the Arabic for the mulberry has "sycamine," or "sycamore," of which, chap. xix4. Christ, moreover, exalts the power of faith, that He might implant in the Apostles an additional desire of increasing its keenness, and of praying for its gift to them; for He who gave to men the mind and desire of praying, wished also to increase the faith of those who prayed. Hence He subsequently increased their faith, especially when He sent the Holy Spirit upon them at Pentecost. Hence too, by the strength of their excelling faith, they wrought so great wonders and miracles, converting the whole world; and, lest they should grow proud of such deeds, and become vainglorious, Christ, by the following Parable, teaches them to be humble-minded, and to say, "we are unprofitable servants."
