And the apostles said unto the Lord, Increase our faith.
Read Chapter 17
Ambrose of Milan
AD 397
Or this is said because faith keeps out the unclean spirit, especially since the nature of the tree falls in with this meaning. For the fruit of the mulberryis at first white in the blossom, and being formed from thence grows red, and blackens as it gets ripe. The devil also having by transgression fallen from the white flower of the angelic nature and the bright beams of his power, grows terrible in the black odor of sin.
We may indeed understand that they asked for the increase of that faith by which men believe in the things which they see not; but there is further signified a faith in things, whereby not with the words only, but the things themselves present, we believe. And this shall be, when the Wisdom of God, by whom all things were made, shall reveal Himself openly to His saints face to face.
A mustard seed looks small. Nothing is less noteworthy to the sight, but nothing is stronger to the taste. What does that signify but the very great fervor and inner strength of faith in the church? Sermon
Or our Lord here compares perfect faith to a grain of mustard seed, because it is lowly in appearance, but fervid in heart. But mystically by the mulberry tree, (whose fruit and branches are red with a blood-red color,) is represented the Gospel of the cross, which, through the faith of the Apostles being uprooted by the word of preaching from the Jewish nation, in which it was kept as it were in the lineal stock, was removed and planted in the sea of the Gentiles.
And the Apostles said to the Lord, Increase our faith. The Apostles said this, when, from their little faith, they had been unable to cast out the devil from the lunatic. They then asked for greater faith, as appears from the above words compared with those of S. Matthew 17:19, &c, for Christ made the same reply in each place, "If you had faith as a grain of mustard seed you would move mountains."
They ask, “Add faith to us.” They do not ask simply for faith, for perhaps you might imagine them to be without faith. They rather ask Christ for an addition to their faith and to be strengthened in faith. Faith partly depends on us and partly is the gift of the divine grace. The beginning of faith depends on us and our maintaining confidence and faith in God with all our power. The confirmation and strength necessary for this comes from the divine grace. For that reason, since all things are possible with God, the Lord says that all things are possible for him who believes. The power that comes to us through faith is of God. Knowing this, blessed Paul also says in the first epistle to the Corinthians, “For to one is given through the Spirit the word of wisdom, to another the word of knowledge according to the same Spirit, and to another faith in the same Spirit.” You see that he has placed faith also in the catalogue of spiritual graces. The disciples requested that they might receive...
Increase our faith. The disciples having heard our Saviour inculcating maxims hard to flesh and blood, such as avoiding scandal, and forgiving our enemies, humbly beg their faith may be increased, that they may be able to comply with these maxims; for they had heard Christ say, that every thing was possible to him that believed. (Theophylactus)
Christ compares faith to a grain of mustard seed; because, though the grain be small, it is nevertheless stronger than most herbs. (St. Chrysostom)
He mentions the mustard seed, because, though small in size, it is mightier in power than all the others. He implies then that the least part of faith can do great things. But thought he Apostles did not transplant the mulberry tree, do not you accuse them; for our Lord said not, You shall transplant, but, You shall be able to transplant. But they did not, because there was no need, seeing that they did greater things. But some one will ask, How does Christ say, that it is the least part of faith which can transplant a mulberry tree or a mountain, whereas Paul says that it is all faith which moves mountains? We must then answer, that the Apostle imputes the moving of mountains to all faith, not as though only the whole of faith could do this, but because this seemed a great thing to carnal men on account of the vastness of the body.
The mulberry may be also compared to the devil, for as by the leaves of the mulberry tree certain worms are fed, so the devil, by the imaginations which pr...
But our Lord told them that they asked well, and that they ought to believe steadfastly, forasmuch as faith could do many things; and hence it follows, And the Lord; said, you had faith as a grain. of mustard seed,c. Two mighty acts are here brought together in the same sentence; the transplanting of that which was rooted in the earth, and the planting thereof in the sea, (for what is ever planted in the waves?) by which two things He declares the power of faith.
