Responsorial Psalm — Psalm 31:2-3, 3-4, 17, 25
Clement of Rome
On 30:11
Let your children take part in the instruction that is in Christ, let them learn how powerful with God is humility, how strong is a pure love, how the fear of him is beautiful and great and saves those who live in it in holiness with a pure mind. For he is a searcher of thoughts and desires; his breath is in us, and when he wills, he will take it away.
Second Reading — Romans 3:21-25, 28
Irenaeus
On 3:21
But the servants would then have been proved false, and not sent by the Lord, if Christ on His advent, by being found exactly such as He was previously announced, had not fulfilled their words. Wherefore He said, "Think not that I have come to destroy the law or the prophets; I came not to destroy, but to fulfil. For verily I say unto you, Until heaven and earth pass away, one jot or one tittle shall not pass from the law and the prophets till all come to pass." For by His advent He Himself fulfilled all things, and does still fulfil in the Church the new covenant foretold by the law, onwards to the consummation [of all things]. To this effect also Paul, His apostle, says in the Epistle to the Romans, "But now, without the law, has the righteousness of God been manifested, being witnessed by the law and the prophets; for the just shall live by faith." But this fact, that the just shall live by faith, had been previously announced by the prophets.
On 3:23
It was for this reason, too, that the Lord descended into the regions beneath the earth, preaching His advent there also, and [declaring] the remission of sins received by those who believe in Him. Now all those believed in Him who had hope towards Him, that is, those who proclaimed His advent, and submitted to His dispensations, the righteous men, the prophets, and the patriarchs, to whom He remitted sins in the same way as He did to us, which sins we should not lay to their charge, if we would not despise the grace of God. For as these men did not impute unto us (the Gentiles) our transgressions, which we wrought before Christ was manifested among us, so also it is not right that we should lay blame upon those who sinned before Christ's coming. For "all men come short of the glory of God," and are not justified of themselves, but by the advent of the Lord,-they who earnestly direct their eyes towards His light. And it is for our instruction that their actions have been committed to writing, that we might know, in the first place, that our God and theirs is one, and that sins do not please Him although committed by men of renown; and in the second place, that we should keep from wickedness. For if these men of old time, who preceded us in the gifts [bestowed upon them], and for whom the Son of God had not yet suffered, when they committed any sin and served fleshly lusts, were rendered objects of such disgrace, what shall the men of the present day suffer, who have despised the Lord's coming, and become the slaves of their own lusts? And truly the death of the Lord became [the means of] healing and remission of sins to the former, but Christ shall not die again in behalf of those who now commit sin, for death shall no more have dominion over Him; but the Son shall come in the glory of the Father, requiring from His stewards and dispensers the money which He had entrusted to them, with usury; and from those to whom He had given most shall He demand most. We ought not, therefore, as that presbyter remarks, to be puffed up, nor be severe upon those of old time, but ought ourselves to fear, lest perchance, after [we have come to] the knowledge of Christ, if we do things displeasing to God, we obtain no further forgiveness of sins, but be shut out from His kingdom. And therefore it was that Paul said, "For if [God] spared not the natural branches, [take heed] lest He also spare not thee, who, when thou wert a wild olive tree, wert grafted into the fatness of the olive tree, and wert made a partaker of its fatness."
We ought not, therefore, as that presbyter remarks, to be puffed up, nor be severe upon those of old time, but ought ourselves to fear, lest perchance, after [we have come to] the knowledge of Christ, if we do things displeasing to God, we obtain no further forgiveness of sins, but be shut out from His kingdom.
Gospel — Matthew 7:21-27
Hilary of Poitiers
On 7:21
For obeying God’s will and not calling on His name, shall find the way to the heavenly kingdom.
On 7:21
They even assure themselves of glory for their prophesying in teaching, for their casting out dæmons, for their mighty works; and hence promise themselves the kingdom of heaven, saying, Have we not prophesied in thy name?
On 7:23
But thus the hypocrites boasted, as though they spoke somewhat of themselves, and as though the power of God did not work all these things, being invoked; but reading has brought them the knowledge of His doctrine, and the name of Christ casts out the dæmons. Out of our own selves then is that blessed eternity to be earned, and out of ourselves must be put forth something that we may will that which is good, that we may avoid all evil, and may rather do what He would have us do, than boast of that to which He enables us. These then He disowns and banishes for their evil works, saying, Depart from me, ye that work iniquity.
On 7:24
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.
