21. Not every one that says to me, Lord, Lord, shall enter into the kingdom of heaven; but he that does the will of my Father which is in heaven.
JEROME; As He had said above that those who have the robe of a good life are yet not to be received because of the impiety of their doctrines; so now on the other hand, He forbids is to participate the faith with those who while they are strong in sound doctrine, destroy it with civil works for it is necessary that the servants of God that both their work should be approved by their teaching and their teaching by their works. And therefore He says, Not every one that says to me, Lord, Lord, enters into the kingdom of heaven.
CHRYS. Wherein He seems to touch the Jews chiefly who placed everything in dogmas; as Paul accuses then, If you are called a Jew, and rest in the Law.
PSEUDO-CHRYS. Otherwise; having taught that the false prophets and the true are to be discerned by their fruits, He now goes on to teach more plainly what are the fruits by which we are to discern the godly from the ungodly teachers.
AUG. For even in the very name of Christ we must be on our guard against heretics, and all that understand amiss and love this world, that we may not be deceived, and therefore He says, Not every one that says to me, Lord, Lord. But it may fairly create a difficulty how this is to he reconciled with of the Apostle, No man can say that Jesus is the Lord, but by the Holy Ghost. For we cannot say that those who are not to enter into the kingdom of heaven have the Holy Spirit. But the Apostle uses the word 'say,' to express the will and understanding of him that says it. He only properly says a thing, who by the sound of his voice depresses his will and purpose. But the Lord uses the word in its ordinary sense, for he seems to say who neither wishes nor understands what he says.
JEROME; For Scripture uses to take words for deeds; according to which the Apostle declares, They make confession that they know God, but in works deny him.
AMBROSIASTER; For all truth by whomsoever uttered is from the Holy Spirit.
AUG. Let us not therefore think that this belongs to those fruits of which He had spoken above, when one says to our Lord, Lord, Lord; and thence seems to us to be a good tree; the true fruit spoken of is to do the will of God; whence it follows, But who does the will of my Father which is in heaven, he shall enter into the kingdom of heaven.
HILARY; For obeying God's will and not calling on His name, shall find the way to the heavenly kingdom.
24. Therefore whosoever hears these sayings of mine, and does them, I will liken him to a wise man, which built his house upon a rock:
25. And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
26. And every one that hears these sayings of mine, and does them not, shall be likened to a foolish man, which built his house upon the sand:
27. And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
CHRYS. Because there would be some who would admire the things that were said by the Lord, but would not add that showing forth of them which is in action, He threatens them before, saying, Every man that hears these words of mine, and does them, shall be likened to a wise man.
PSEUDO-CHRYS. 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 amid 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. 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 through out the whole world broken down. He then is like to 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 should 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? Like to the Devil is he that hears the words of Christ, and does them not. For words that are heard, amid 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 anything 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.
RABAN. Or the great ruin is to be understood that with which the Lord will say to them that hear and do not, Go you into everlasting fire.
JEROME; 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.
HILARY; Otherwise; By the showers He signifies the allurements of smooth and gently invading pleasures, with which the faith is at first watered as with spreading rills, afterwards Comes down the rush of torrent floods, that is, the motions of fiercer desire, and lastly, the whole force of the driving tempests rages against it, that is, the universal spirits of the Devil's reign attack it.
AUG. Otherwise; Rain, when it is put to denote any evil, is understood as the darkness of superstition; rumors 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 He noted, that when He said, He that hears 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.
