ACC ~ Matthew 17 v20

FAITH AS A GRAIN OF MUSTARD SEED

ORIGEN: The mountains here spoken of, in my opinion, are the hostile powers that have their being in a flood of great wickedness, such as are settled down, so to speak, in some souls of various people. But when someone has total faith, such that he no longer disbelieves in anything found in holy Scripture and has faith like that of Abraham, who so believed in God to such a degree that his faith was reckoned to him as righteousness, [1] then he has all faith like a grain of mustard seed. Then such a man will say to this mountain—I mean in this case the deaf and dumb spirit in him who is said to be epileptic—“Move from here to another place.” It will move. This means it will move from the suffering person to the abyss. The apostle, taking this as his starting point, said with apostolic authority, “If I have all faith, so as to remove mountains.” [2] For he who has all faith—which is like a grain of mustard seed—moves not just one mountain but also more just like it. And nothing will be impossible for the person who has so much faith.

Let us examine also this statement: “This kind is not cast out except through prayer and fasting.” [3] If at any time it is necessary that we should be engaged in the healing of one suffering from such a disorder, we are not to adjure nor put questions nor speak to the impure spirit as if it heard. But [by] devoting ourselves to prayer and fasting, we may be successful as we pray for the sufferer, and by our own fasting we may thrust out the unclean spirit from him. COMMENTARY ON MATTHEW 13.7.

SAY TO THIS MOUNTAIN:

MOVE

CHRYSOSTOM: The disciples seem to me to be in anxiety and fear that they had lost the grace with which they had been entrusted. For they had received power over unclean demons. So they approached him in private and asked him the question, not out of shame (for if the matter had got out and they were criticized, it would have been superfluous for the future to have been ashamed of admitting it in their words) but because what they were going to ask him was secret and of great moment.

What, then, does Christ say? “Because of your little faith. For truly, I say to you, if you have faith as a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible to you.” But if you say “Where did they move a mountain?” I will say that they did things much greater than that in raising up innumerable dead. For moving a mountain and moving death from a body are not at all comparable. After them other saints, far inferior to the disciples, are said to have moved mountains when necessity demanded. It is clear that the disciples also would have done so had necessity demanded. But if there was never need at that time, do not find fault with them. THE GOSPEL OF MATTHEW, HOMILY 57.4. [1]
