First Reading — Jeremiah 30:1-2, 12-15, 18-22
John Cassian
On 30:11
Although we say that trial is twofold, that is, in prosperity and in adversity, yet you must know that all people are tried in three different ways. Often they are tried for their probation, sometimes for their improvement, and in some cases because their sins deserve it. For their probation indeed! We read that the blessed Abraham and Job and many of the saints endured countless tribulations.… For improvement, because God chastens his righteous ones for some small and venial sins or to raise them to a higher state of purity, and he delivers them over to various trials that he may purge away all their unclean thoughts, and, to use the prophet's word, the "dross," which he sees to have collected in their secret parts. Thus may he transmit them like pure gold to the judgment to come, as he allows nothing to remain in them for the fire of judgment to discover when hereafter it searches them with penal torments according to this saying: "Many are the tribulations of the righteous." … To whom under the figure of Jerusalem the following words are spoken by Jeremiah, in the person of God: "I will make a full end of all the nations among whom I scattered you, but of you I will not make a full end. I will discipline you in just measure, and I will by no means leave you unpunished." … But as a punishment for sins, the blows of trial are inflicted, as where the Lord threatens that he will send plagues on the people of Israel: "I will send the teeth of beasts on them, with the fury of creatures that trail on the ground," and "In vain have I struck your children. They have not received correction." … We find, it is true, a fourth way also in which we know on the authority of Scripture that some sufferings are brought on us simply for the manifestation of the glory of God and his works, according to these words of the Gospel: "Neither did this man sin nor his parents, but that the works of God might be manifested in him," and again, "This sickness is not to death, but for the glory of God that the Son of God may be glorified by it." … The perfect person will always remain steadfast in either kind of trial; now let us return to it once more.
Responsorial Psalm — Psalm 102:16-18, 19-21, 29, 22-23
Tertullian
On 101:25
But it is not thus that the prophets and the apostles have told us that the world was made by God merely appearing and approaching matter. They did not even mention any matter but [said] that Wisdom was first set up, the beginning of his ways, for his works. Then that the Word was produced, "through whom all things were made, and without whom nothing was made." Indeed, "by the Word of the Lord were the heavens made, and all their hosts by the breath of his mouth." He is the Lord's right hand, indeed his two hands, by which he worked and constructed the universe. "For," he says, "the heavens are the works of your hands." Wherewith "he has measured out the heaven, and the earth with a span." Do not be willing so to cover God with flattery, as to contend that he produced by his mere appearance and simple approach so many vast substances, instead of rather forming them by his own energies. For this is proved by Jeremiah when he says, "God has made the earth by his power; he has established the world by his wisdom and has stretched out the heaven by his understanding." These are the energies by the stress of which he made this universe. His glory is greater if he labored.
On 101:25–26
In like manner David says, "The heavens, the works of your hands, shall themselves perish. For even as a garment shall he change them, and they shall be changed." Now to be changed is to fall from that primitive state that they lose while undergoing the change. "And the stars too shall fall from heaven, even as a fig tree casts its green figs when it is shaken by a mighty wind." "The mountains shall melt like wax at the presence of the Lord"; that is, "when he rises to shake terribly the earth." "But I will dry up the pools"; and "they shall seek water, and they shall find none." Even "the sea shall be no more." Now if any person should go so far as to suppose that all these passages ought to be spiritually interpreted, he will still be unable to deprive them of the true accomplishment of those issues that must come to pass just as they have been written. For all figures of speech necessarily arise out of real things, not out of chimerical ones; because nothing is capable of imparting anything of its own for a similitude, except it actually be that very thing that it imparts in the similitude. I return therefore to the principle that defines that all things that have come from nothing shall return at last to nothing.
Gospel — Matthew 14:22-36
Hilary of Poitiers
On 14:22
But Christ coming in the end shall find His Church wearied, and tossed by the spirit of Anti-Christ, and by the troubles of the world. And because by their long experience of Anti-Christ they will be troubled at every novelty of trial, they shall have fear even at the approach of the Lord, suspecting deceitful appearances. But the good Lord banishes their fear, saying, It is I; and by proof of His presence takes away their dread of impending shipwreck.
On 14:22
That when Peter was seized with fear, the Lord gave him not power of coming to Him, but held him by the hand and sustained him, this is the signification thereof; that He who alone was to suffer for all alone forgave the sins of all; and no partner is admitted into that which was bestowed upon mankind by one.
On 14:23
Or, that He is alone in the evening, signifies His sorrow at the time of His passion, when the rest were scattered from Him in fear.
On 14:23
That He commands His disciples to enter the ship and to go across the sea, while He sends the multitudes away, and after that He goes up into the mountain to pray; He therein bids us to be within the Church, and to be in peril until such time as returning in His splendour He shall give salvation to all the people that shall be remaining of Israel, and shall for give their sins; and having dismissed them into His Father’s kingdom, returning thanks to His Father, He shall sit down in His glory and majesty. Meanwhile the disciples are tossed by the wind and the waves; struggling against all the storms of this world, raised by the opposition of the unclean spirit.
On 14:25
The first watch Was therefore of the Law, the second of the Prophets, the third His coming in the flesh, the fourth His return in glory.
On 14:28
Or; That Peter alone out of all the number of those that were in the vessel has courage to answer, and to pray that the Lord would bid him come to Him upon the waters, figures the frowardness of his will in the Lord’s passion, when following after the Lord’s steps he endeavoured to attain to despise death. But his fearfulness shews his weakness in his after trial, when through fear of death, he was driven to the necessity of denial. His crying out here is the groaning of his repentance there.
On 14:33
Also by this entrance of Christ into the boat, and the calm of the wind and sea thereupon, is pointed out the eternal peace of the Church, and that rest which shall be after His return in glory. And forasmuch as He shall then appear manifestly, rightly do they all cry out now in wonder, Truly thou art the Son of God. For there shall then be a free and public confession of all men that the son of God is come no longer in lowliness of body, but that He has given peace to the Church in heavenly glory.
On 14:36
Otherwise; When the times of the Law were ended, and five thousand out of Israel were entered within the Church, it was then that the people of believers met Him, then those that were saved out of the Law by faith set before the Lord the rest of their sick and weak; and they that were thus brought sought to touch the hem of His garment, because through their faith they would be healed. And as the virtue of the hem proceeded from the whole garment, so the virtue of the grace of the Holy Spirit went forth from our Lord Jesus Christ, and imparted to the Apostles, who proceeded as it were from the same body, administers salvation to such as desire to touch.
