First Reading — Wisdom 12:13, 16-19
Augustine of Hippo
On 12:18
Why did he not say "in wrath" but "as in wrath"? Because God does everything with absolute tranquility. Indeed, it is also written, "You, master of strength, judge with gentleness." Therefore, even when he threatens he does not become angry, nor is he disturbed in any way. It calls him angry because he punishes and does justice. Similarly, people who do not want to amend their lives are as though they were alive, but they do not live, because vengeance for the first sin, and for those that they have added, hangs over them. This vengeance is called the wrath of God, because it proceeds from God's judgment. Thus the Lord says of the one who does not believe, "but the wrath of God hangs over him." We also, being born mortal, were under the wrath of God. Therefore the apostle says, "We were once by nature deserving of wrath, like the others." What does "by nature deserving of wrath" mean, if not that we carry with us the wrath of the first sin? But if we convert, wrath ceases, and grace is offered to us. If, however, you do not want to convert, you add other offenses to the ones you were born with. And, "as in wrath," you will be devoured even in the present time.
On 12:18
How is it that it is written, "Power is in your hands whenever you want," as if God needs a period of time to carry out some work? Or, rather, are all things accomplished by God (as we say) like an artist thinks out a design—not over an extended period of time—but by that power that accomplishes in an enduring way even those things that we see are not enduring but passing? Even with our own speech, when some words pass away while others follow, we should not think that the same thing happens with the thought that gave rise to the expression we just finished. Consequently, although God, who exercises power when he wishes, accomplishes his works without the passage of time, nonetheless temporal natures themselves carry out their movements within time.
Responsorial Psalm — Psalm 86:5-6, 9-10, 15-16
Irenaeus
On 85:13
For they do not choose to understand, that if these things are as they say, the Lord Himself, in whom they profess to believe, did not rise again upon the third day; but immediately upon His expiring on the cross, undoubtedly departed on high, leaving His body to the earth. But the case was, that for three days He dwelt in the place where the dead were, as the prophet says concerning Him: "And the Lord remembered His dead saints who slept formerly in the land of sepulture; and He descended to them, to rescue and save them." And the Lord Himself says, "As Jonas remained three days and three nights in the whale's belly, so shall the Son of man be in the heart of the earth." [Matthew 12:40] Then also the apostle says, "But when He ascended, what is it but that He also descended into the lower parts of the earth?" [Ephesians 4:9] This, too, David says when prophesying of Him, "And thou hast delivered my soul from the nethermost hell;" and on His rising again the third day, He said to Mary, who was the first to see and to worship Him, "Touch Me not, for I have not yet ascended to the Father; but go to the disciples, and say unto them, I ascend unto My Father, and unto your Father." [John 20:17]
If, then, the Lord observed the law of the dead, that He might become the first-begotten from the dead, and tarried until the third day "in the lower parts of the earth;" [Ephesians 4:9] then afterwards rising in the flesh, so that He even showed the print of the nails to His disciples, He thus ascended to the Father;— [if all these things occurred, I say], how must these men not be put to confusion, who allege that "the lower parts" refer to this world of ours, but that their inner man, leaving the body here, ascends into the super-celestial place? For as the Lord "went away in the midst of the shadow of death," where the souls of the dead were, yet afterwards arose in the body, and after the resurrection was taken up [into heaven], it is manifest that the souls of His disciples also, upon whose account the Lord underwent these things, shall go away into the invisible place allotted to them by God, and there remain until the resurrection, awaiting that event; then receiving their bodies, and rising in their entirety, that is bodily, just as the Lord arose, they shall come thus into the presence of God. "For no disciple is above the Master, but every one that is perfect shall be as his Master." [Luke 6:40] As our Master, therefore, did not at once depart, taking flight [to heaven], but awaited the time of His resurrection prescribed by the Father, which had been also shown forth through Jonas, and rising again after three days was taken up [to heaven]; so ought we also to await the time of our resurrection prescribed by God and foretold by the prophets, and so, rising, be taken up, as many as the Lord shall account worthy of this [privilege].
Second Reading — Romans 8:26-27
Clement of Alexandria
On 8:26
If he but form the thought in the secret chamber of his soul, and call on the Father "with unspoken groanings," He is near, and is at his side, while yet speaking.
Gospel — Matthew 13:24-43
Hilary of Poitiers
On 13:31
Or; The Lord compares Himself to a grain of mustard seed, sharp to the taste, and the least of all seeds, whose strength is extracted by bruising.
On 13:32
This grain then when sown in the field, that is, when seized by the people and delivered to death, and as it were buried in the ground by a sowing of the body, grew up beyond the size of all herbs, and exceeded all the glory of the Prophets. For the preaching of the Prophets was allowed as it were herbs to a sick man; but now the birds of the air lodge in the branches of the tree. By which we understand the Apostles, who put forth of Christ’s might, and overshadowing the world with their boughs, are a tree to which the Gentiles flee in hope of life, and having been long tossed by the winds, that is by the spirits of the Devil, may have rest in its branches.
On 13:33
Or otherwise; The Lord compares Himself to leaven; for leaven is produced from meal, and communicates the power that it has received to a heap of its own kind. The woman, that is the Synagogue, taking this leaven hides it, that is by the sentence of death; but it working in the three measures of meal, that is equally in the Law, the Prophets, and the Gospels, makes all one; so that what the Law ordains, that the Prophets announce, that is fulfilled in the developements of the Gospels. But many, as I remember, have thought that the three measures refer to the calling of the three nations, out of Shem, Ham, and Japhet. But I hardly think that the reason of the thing will allow this interpretation; for though these three nations have indeed been called, yet in them Christ is shewn and not hidden, and in so great a multitude of unbelievers the whole cannot be said to be leavened.
