First Reading — Sirach 27:30-28:7
Cyprian
On 27:5
After shipwrecks, after scourgings, after many and terrible tortures of the flesh and body, the apostle Paul says that he is not hurt but benefited by his adversity because through such terrible affliction he might more truly be proved. "There was given to me," he says, "a thorn in the flesh, the messenger of Satan to buffet me, that I should not be lifted up. I sought the Lord three times about this so that it might leave me; and he said to me, My grace is sufficient for you, for strength is made perfect in weakness." When, therefore, weakness and inefficiency and any destruction seize us, then our strength is made perfect. Then, if our faith is put to the test, it will stand fast and receive a crown, as it is written: "The furnace tries the vessels of the potter, and the trial of tribulation tests just people." This, in short, is the difference between us and others who do not know God, that in misfortune they complain and murmur, while adversity does not call us away from the truth of virtue and faith but strengthens us by its suffering.
Responsorial Psalm — Psalm 103:1-2, 3-4, 9-10, 11-12
Gregory of Nyssa
On 102:8
God is not an expression, and he does not have his essence in voice or utterance. God is of himself what also he is believed to be. He is named by those who call on him, not what he is essentially (for the nature of him who alone is unspeakable), but he receives his names from what are believed to be his works in regard to our life. To take an instance ready at hand, when we speak of him as God, we so name him from his overlooking and surveying all things and seeing through the things that are hidden. But if his essence is prior to his works, and if we understand his works by our senses and express them in words as we are best able, why should we be afraid of calling things by words of later origin than themselves? For if we stop interpreting any of the attributes of God until we understand them, and if we understand them only by what his works teach us, and if his power precedes its exercise and depends on the will of God, while his will resides in the spontaneity of the divine nature, are we not clearly taught that the words that represent things are of later origin than the things themselves and that the words that are framed to express the operations of things are reflections of the things themselves? And that this is so, we are clearly taught by holy Scripture, by the mouth of great David, when, as by certain peculiar and appropriate names, derived from his contemplation of the works of God, he thus speaks of the divine nature: "The Lord is full of compassion and mercy, long-suffering, and of great goodness." Now what do these words tell us? Do they indicate his operations or his nature? No one will say that they indicate anything but his operations. At what time, then, after showing mercy and pity, did God acquire his name from the display of his works? Was it before a person's life began? But who was there to be the object of pity? Was it, then, after sin entered into the world? But sin entered after humankind. The exercise, therefore, of pity, and the name itself, came after humanity. What then? Will our adversary [Eunomius], wise as he is above the prophets, convict David of error in applying names to God derived from his opportunities of knowing him? Or, in contending with him, will he use against him the pretense in his stately passage as out of a tragedy, saying that "he glories in the most blessed life of God with names drawn from human imagination, whereas it gloried in itself alone, long before people were born to imagine them"? The psalmist's advocate will readily admit that the divine nature gloried in itself alone even before the existence of human imagination but will contend that the human mind can speak only so much in respect of God as its capacity, instructed by his works, will allow. "For," as says the Wisdom of Solomon, "by the greatness and beauty of the creatures proportionably the Maker of them is seen."
Second Reading — Romans 14:7-9
Irenaeus
On 14:9
As it has been clearly demonstrated that the Word, who existed in the beginning with God, by whom all things were made, who was also always present with mankind, was in these last days, according to the time appointed by the Father, united to His own workmanship, inasmuch as He became a man liable to suffering, [it follows] that every objection is set aside of those who say, "If our Lord was born at that time, Christ had therefore no previous existence." For I have shown that the Son of God did not then begin to exist, being with the Father from the beginning; but when He became incarnate, and was made man, He commenced afresh the long line of human beings, and furnished us, in a brief, comprehensive manner, with salvation; so that what we had lost in Adam-namely, to be according to the image and likeness of God-that we might recover in Christ Jesus.
For as it was not possible that the man who had once for all been conquered, and who had been destroyed through disobedience, could reform himself, and obtain the prize of victory; and as it was also impossible that he could attain to salvation who had fallen under the power of sin,-the Son effected both these things, being the Word of God, descending from the Father, becoming incarnate, stooping low, even to death, and consummating the arranged plan of our salvation, upon whom [Paul], exhorting us unhesitatingly to believe, again says, "Who shall ascend into heaven? that is, to bring down Christ; or who shall descend into the deep? that is, to liberate Christ again from the dead." Then he continues, "If thou shall confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shall be saved." And he renders the reason why the Son of God did these things, saying, "For to this end Christ both lived, and died, and revived, that He might rule over the living and the dead."
Gospel — Matthew 18:21-35
Origen
On 18:21
Or, because the number six seems to denote toil and labour, and the number seven repose, He says that forgiveness should be given to all brethren who live in this world, and sin in the things of this world. But if any commit transgressions beyond these things, he shall then have no further forgiveness.
On 18:23
The Son of God, as He is wisdom, righteousness, and truth (vid. 1 Cor. 1:30.), so is He a kingdom; not indeed any of those which are beneath, but all those which are above, reigning over those in whose senses reigns justice and the other virtues; these are made of heaven because they bear the image of the heavenly. This kingdom of heaven then, i. e. the Son of God, when He was made in the likeness of sinful flesh, was then like to a king, in uniting man to himself.
On 18:23
The servants, in these parables, are only they who are employed in dispensing the word, and to whom this business is committed.
On 18:23
The King takes account of our, whole life then, when we must all be presented before the judgment-seat of Christ. (2 Cor. 5:10.) We mean not this so as that any should think that the business itself must needs require a long time. For God, when He will scrutinize the minds of all, will by some undescribable power cause every thing that every man has done to pass speedily before the mind of each. He says, And when he began to take account, because the beginning of the judgment is that it begin from the house of God. (1 Pet. 4:17.) At His beginning to take account there is brought unto Him one who owes Him many talents; one, that is, who had wrought great evils; one on whom much had been enjoined, and had yet brought no gain; who perhaps had destroyed as many men as he owed talents; one who was therefore become a debtor of many talents, because he had followed the woman sitting upon a talent of lead, whose name is Iniquity. (Zech. 5:7.)
On 18:23
He therefore, as I suppose, took him by the throat, because he had come forth from the king; for he would not have so handled his fellow servant, if he had not gone forth from the king.
On 18:23
Observe the exactness of Scripture; the servant who owed many talents fell down, and worshipped the king; he who owed the hundred denarii falling down, did not worship, but besought his fellow servant, saying, Have patience. But the ungrateful servant did not even respect the very words which had saved himself, for it follows, but he would not.
On 18:23
He seeks to instruct us, that we should be ready to shew clemency to those who have done us harm, especially if they offer amends, and plead to have forgiveness.
