Matthew 7:29

(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. (De Cons. Ev. ii. 19.) From that which is here said, He seems to have left the crowd of disciples—those out of whom He chose twelve, whom He called Apostles—but Matthew omits to mention it. For to His disciples only, Jesus seems to have held this Sermon, which Matthew recounts, Luke omits. That after descending into a plain He held another like discourse, which Luke records, and Matthew omits. Still it may be supposed, that, as was said above, He delivered one and the same Sermon to the Apostles, and the rest of the multitude present, which has been recorded by Matthew and Luke, in different words, but with the same truth of substance; and this explains what is here said of the multitude wondering. (Serm. in Mont. ii. 25. i. 10, et seq.) This is what is signified in the eleventh Psalm, I will deal mightily with him; the words of the Lord are pure words, silver tried in the fire, purified of earth, purged seven times. (Ps. […]

Or; They measure the efficacy of His power, by the might of His words.

(Verse 29.) For he was teaching them as one having authority, and not as the scribes and Pharisees. For they taught the people, what was written in Moses and the Prophets. But Jesus, being like God and the Lord of Moses himself, for the freedom of his will, either added to the law what seemed less, or changing it, preached to the people, as we also read above: It was said to the ancients: But I say to you.

The mind of man when satisfied reasonably brings forth praise, but when overcome, wonder. For whatever we are not able to praise worthily, we admire. Yet their admiration pertained rather to Christ's glory than to their faith, for had they believed on Christ, they would not have wondered. For wonder is raised by whatever surpasses the appearance of the speaker or actor; and thence we do not wonder at what is done or said by God, because all things are less than God's power. But it was the multitude that wondered, that is the common people, not the chief among the people, who are not wont to hear with the desire of learning; but the simple folk heard in simplicity; had others been present they would have broken up their silence by contradicting, for where the greater knowledge is, there is the stronger malice. For he that is in haste to be first, is not content to be second.

Yet was it rather natural for them to grieve at the unpleasantness of His sayings, and to shudder at the loftiness of His injunctions; but now so great was the power of the Teacher, that many of them were even caught thereby, and thrown into very great admiration, and persuaded by reason of the sweetness of His sayings, not even when He ceased to speak, to depart from Him at all afterwards. For neither did the hearers depart, He having come down from the mountain, but even then the whole auditory followed Him; so great a love for His sayings had He instilled into them. But they were astonished most of all at His authority. For not with reference to another, like the prophet and Moses, did He say what He said; but everywhere indicating Himself to be the person that had the power of deciding. For so, when setting forth His laws, He still kept adding, "But I say unto you." And in reminding them of that day, He declared Himself to be the judge, both by the punishments, and by the honors. And yet it was likely that this too would disturb them. For if, when they saw Him by His works showing forth His authority, the scribes were for stoning and persecuting Him; while there were words only to prove this, how was it other than likely for them to be offended? and especially when at first setting out these things were said, and before He had given proof of His own power? But however, they felt nothing of this; for when the heart and mind is candid, it is easily persuaded by the words of the truth. And this is just why one sort, even when the miracles were proclaiming His power, were offended; while the other on hearing mere words were persuaded and followed Him.
