Matthew 7:26

Wherefore also He made His argument more expressive, by trying its force in a parable; for it was not the same thing to say, "The virtuous man shall be impregnable but the wicked easily subdued," as to suppose a rock, and a house, and rivers, and rain, and wind, and the like. "And every one," saith He, "that heareth these sayings of mine, and doeth them not, shall be likened to a foolish man, which built his house upon the sand." And well did He call this man "foolish": for what can be more senseless than one building a house on the sand, and while he submits to the labor, depriving himself of the fruit and refreshment, and instead thereof undergoing punishment? For that they too, who follow after wickedness, do labor, is surely manifest to every one: since both the extortioner, and the adulterer, and the false accuser, toil and weary themselves much to bring their wickedness to effect; but so far from reaping any profit from these their labors, they rather undergo great loss. For Paul too intimated this when he said, "He that soweth to his flesh, shall of his flesh reap corruption." To this man are they like also, who build on the sand; as those that are given up to fornication, to wantonness, to drunkenness, to anger, to all the other things. Such an one was Ahab, but not such Elijah (since when we have put virtue and vice along side of one another, we shall know more accurately the difference): for the one had built upon the rock, the other on the sand; wherefore though he were a king, he feared and trembled at the prophet, at him that had only his sheepskin. Such were the Jews but not the apostles; and so though they were few and in bonds, they exhibited the steadfastness of the rock; but those, many as they were, and in armor, the weakness of the sand. For so they said, "What shall we do to these men?" Seest thou those in perplexity, not who are in the hands of others, and bound, but who are active in holding down and binding? And what can be more strange than this? Hast thou hold of the other, and art yet in utter perplexity? Yes, and very naturally. For inasmuch as they had built all on the sand, therefore also were they weaker than all. For this cause also they said again, "What do ye, seeking to bring this man's blood upon us?" What saith he? Dost thou scourge, and art thou in fear? entreatest thou despitefully, and art in dismay? Dost thou judge, and yet tremble? So feeble is wickedness. But the Apostles not so, but how? "We cannot but speak the things which we have seen and heard." Seest thou a noble spirit? seest thou a rock laughing waves to scorn? seest thou a house unshaken? And what is yet more marvellous; so far from turning cowards themselves at the plots formed against them, they even took more courage, and cast the others into greater anxiety. For so he that smites adamant, is himself the one smitten; and he that kicks against the pricks, is himself the one pricked, the one on whom the severe wounds fall: and he who is forming plots against the virtuous, is himself the one in jeopardy. For wickedness becomes so much the weaker, the more it sets itself in array against virtue. And as he who wraps up fire in a garment, extinguishes not the flame, but consumes the garment; so he that is doing despite to virtuous men, and oppressing them, and binding them, makes them more glorious, but destroys himself.

Or otherwise; On sand which is loose and cannot be bound into one mass, all the doctrine of heretics is built so as to fall.

(Serm. in Mont. in fin.) Otherwise; Rain, when it is put to denote any evil, is understood as the darkness of superstition; rumours of men are compared to winds; the flood signifies the lust of the flesh, as it were flowing over the land, and because what is brought on by prosperity is broken off by adversity. None of these things does he fear who has his house founded upon a rock, that is, who not only hears the command of the Lord, but who also does it. And in all these he submits himself to danger, who hears and does not. For no man confirms in himself what the Lord commands, or himself hears, but by doing it. But it should be noted, that when he said, He that heareth these words of mine, He shows plainly enough that this sermon is made complete by all those precepts by which the Christian life is formed, so that with good reason they that desire to live according to them, may be compared to one that builds on a rock.

He said not, I will account him that hears and does, as wise; but, He shall be likened to a wise man. He then that is likened is a man; but to whom is he likened? To Christ; but Christ is the wise man who has built His house, that is, the Church, upon a rock, that is, upon the strength of the faith. The foolish man is the Devil, who has built his house, that is, all the ungodly, upon the sand, that is, the insecurity of unbelief, or upon the carnal, who are called the sand on account of their barrenness; both because they do not cleave together, but are scattered through the diversity of their opinions, and because they are innumerable. The rain is the doctrine that waters a man, the clouds are those from which the rain falls. Some are raised by the Holy Spirit, as the Apostles and Prophets, and some by the spirit of the Devil, as are the heretics. The good winds are the spirits of the different virtues, or the Angels who work invisibly in the senses of men, and lead them to good. The bad winds are the unclean spirits. The good floods are the Evangelists and teachers of the people; the evil floods are men full of an unclean spirit, and overflowing with many words; such are philosophers and the other professors of worldly wisdom, out of whose belly come rivers of dead water. The Church then which Christ has founded, neither the rain of false doctrine shall sap, nor the blast of the Devil overturn, nor the rush of mighty floods remove. Nor does it contradict this, that certain of the Church do fall; for not all that are called Christians, are Christ's, but, The Lord knows them that are his. (2 Tim. 2:19.) But against that house that the Devil has built comes down the rain of true doctrine, the winds, that is, the graces of the Spirit, or the Angels; the floods, that is, the four Evangelists and the rest of the wise; and so the house falls, that is, the Gentile world, that Christ may rise; and the ruin of that house was great, its errors broken up, its falsehoods laid open, its idols throughout the whole world broken down. He then is like unto Christ, who hears Christ's words, and does them; for he builds on a rock, that is, upon Christ, who is all good, so that on whatsoever kind of good any one shall build, he may seem to have built upon Christ. But as the Church built by Christ cannot be thrown down, so any such Christian who has built himself upon Christ, no adversity can overthrow, according to that, Who shall separate us from the love of Christ? (Rom. 8:35.) Like to the Devil is he that hears the words of Christ, and does them not. For words that are heard, and are not done, are likened to sand, they are dispersed and shed abroad. For the sand signifies all evil, or even worldly goods. For as the Devil's house is overthrown, so such as are built upon the sand are destroyed and fall. And great is that ruin if he have suffered any thing to fail of the foundation of faith; but not if he have committed fornication, or homicide, because he has whence he may arise through penitence, as David.
