First Reading — Isaiah 1:10-17
Clement of Rome
On 1:16–20
The ministers of the grace of God have, by the Holy Spirit, spoken of repentance; and the Lord of all things has himself declared with an oath regarding it, "As I live, says the Lord, I desire not the death of the sinner, but rather his repentance;" [Ezekiel 33:11] adding, moreover, this gracious declaration, "Repent, O house of Israel, of your iniquity." [Ezekiel 18:30] Say to the children of my people, Though your sins reach from earth to heaven, and though they be redder than scarlet, and blacker than sack-cloth, yet if you turn to me with your whole heart, and say, Father! I will listen to you, as to a holy people. [2 Chronicles 7:14] And in another place He speaks thus: "Wash you and become clean; put away the wickedness of your souls from before my eyes; cease from your evil ways, and learn to do well; seek out judgment, deliver the oppressed, judge the fatherless, and see that justice is done to the widow; and come, and let us reason together. He declares, Though your sins be like crimson, I will make them white as snow; though they be like scarlet, I will whiten them like wool. And if you be willing and obey me, you shall eat the good of the land; but if you refuse, and will not hearken unto me, the sword shall devour you, for the mouth of the Lord has spoken these things." [Isaiah 1:16-20] Desiring, therefore, that all His beloved should be partakers of repentance, He has, by His almighty will, established [these declarations].
Responsorial Psalm — Psalm 50:8-9, 16bc-17, 21, 23
Clement of Rome
On 49:14
The Master, brothers, has need of nothing at all. He desires not anything of anyone, save to confess to him.
On 49:23
Let us … earnestly strive to be found in the number of those that wait for him, in order that we may share in his promised gifts. But how, beloved, shall this be done? If our understanding is fixed by faith toward God; if we earnestly seek the things that are pleasing and acceptable to him; if we do the things that are in harmony with his blameless will; and if we follow the way of truth, casting away from us all unrighteousness and iniquity, along with all covetousness, strife, evil practices, deceit, whispering and evil speaking, all hatred of God, pride and haughtiness, vainglory and ambition. For they that do such things are hateful to God; and not only they that do them, but also those that take pleasure in them that do them.
Gospel — Matthew 10:34-11:1
Hilary of Poitiers
On 10:5
The promulgation of the Law deserved also the first preaching of the Gospel; and Israel was to have less excuse for its crime, as it had experienced more care in being warned.
On 10:5
Though they are here called sheep, yet they raged against Christ with the tongues and throats of wolves and vipers.
On 10:5
The exercise of the Lord’s power is wholly entrusted to the Apostles, that they who were formed in the image of Adam, and the likeness of God, should now obtain the perfect image of Christ; and whatever evil Satan had introduced into the body of Adam, this they should now repair by communion with the Lord’s power.
On 10:9
The girdle is the making ready for the ministry, the girding up that we may be active in duty; we may suppose that the forbidding money in the girdle is to warn us from suffering any thing in the ministry to be bought and sold. We are not to have a scrip by the way, that is, we are to leave all care of our worldly substance; for all treasure on earth is hurtful to the heart, which will be there where the treasure is. Not two coats, for it is enough to have once put on Christ, nor after true knowledge of Him ought we to be clothed with any other garment of heresy or law. Not shoes, because standing on holy ground as was said to Moses not covered with the thorns and prickles of sin, we are admonished to have no other preparation of our walk than that we have received from Christ.
On 10:9
Neither a staff; that is, We are not to seek rights of extraneous power, having a rod from the root of Jesse.
On 10:11
Figuratively, The Lord teaches us not to enter the houses or to mix in the acquaintance of those who persecute Christ, or who are ignorant of Him; and in each town to enquire who among them is worthy, i. e. where there is a Church wherein Christ dwells; and not to pass to another, because this house is worthy, this host is our right host. But there would be many of the Jews who would be so well disposed to the Law, that though they believed in Christ because they admired His works, yet they would abide in the works of the Law; and others again who, desiring to make trial of that liberty which is in Christ, would feign themselves ready to forsake the Law for the Gospel; many also would be drawn aside into heresy by perverse understanding. And since all these would falsely maintain that with them only was Catholic verity, therefore we must with great caution seek out the house, i. e. the Church.
On 10:14
The Apostles salute the house with the prayer of peace; yet so as that peace seems rather spoken than given. For their own peace which was the bowels of their pity ought not to rest upon the house if it were not worthy; then the sacrament of heavenly peace could be kept within the Apostles own bosom. Upon such as rejected the precepts of the heavenly kingdom an eternal curse is left by the departure of the Apostles, and the dust shaken from their feet; And whosoever shall not receive you, nor hear your words, when ye go out of that house, or that town, cast the dust off your feet. For he that lives in any place seems to have a kind of fellowship with that place. By the casting the dust off the feet therefore all that belonged to that house is left behind, and nothing of healing or soundness is borrowed from the footsteps of the Apostles having trod their soil.
On 10:16
He first attempted the softer sex, allured her by hope, and promised a share of immortality. Do you in like manner seize every opportunity, look well into each man’s nature and inclination, use wisdom of speech, reveal hope of good things to come; that what he promised falsely we may preach truly according to God’s promise, that they that believe shall be like to the Angels.
On 10:16
And by this their testimony not only was all excuse of ignorance of His divinity taken away from their persecutors, but also to the Gentiles was opened the way of believing on Christ, who was thus devotedly preached by the voices of the confessors among the flames of persecution; and this is that He adds, and the Gentiles.
On 10:20
For our faith, observing all the precepts of the Divine will, will be instructed with an answer according to knowledge, after the example of Abraham, to whom when he had given up Isaac, there was not wanting a ram for a victim. For it is not ye who speak, but the Spirit of your Father that speaketh in you.
On 10:23
Otherwise; He exhorts to fly from place to place; for His preaching driven from Judæa, first passed into Greece; then, wearied with divers sufferings of the Apostles up and down the cities of Greece, it takes an abiding refuge in the rest of the Gentile world. But to shew that the Gentiles would believe the preaching of the Apostles, but that the remnant of Israel should only believe at His second coming, He adds, Ye shall not have completed the cities of Israel; i. e. After the fulness of the Gentiles is brought in, that which remains of Israel to fill up the number of the Saints shall be called into the Church in Christ’s future coming to glory.
On 10:24
For the Lord, the Light eternal, the Captain of the faithful, the Parent of immortality, set before His disciples this solace of the sufferings that should come upon them, that we should embrace it as our glory when we are made like to our Lord in suffering; whence He says, The disciple is not above his master, nor the slave above his lord.
On 10:26
Therefore neither threatening, nor evil speaking, nor power of their enemies should move them, seeing the judgment-day will disclose how empty, how nought all these were.
On 10:28
Therefore they ought to inculcate constantly the knowledge of God, and the profound secret of evangelic doctrine, to be revealed by the light of preaching; having no fear of those who have power only over the body, but cannot reach the soul; Fear not those that kill the body, but cannot kill the soul.
On 10:29
Figuratively; That which is sold is our soul and body, and that to which it is sold, is sin. They then who sell two sparrows for a farthing, are they who sell themselves for the smallest sin, born for flight, and for reaching heaven with spiritual wings. (vid. Ps. 124:7.) Caught by the bait of present pleasures, and sold to the enjoyment of the world, they barter away their whole selves in such a market. It is of the will of God that one of them rather soar aloft; but the law proceeding according to God’s appointment decrees that one of them should fall. In like manner as, if they soared aloft they would become one spiritual body; so, when sold under sin, the soul gathers earthly matter from the pollution of vice, and there is made of them one body which is committed to earth.
On 10:29
For it is an unworthy task to number things that are to perish. Therefore that we should know that nothing of us should perish, we are told that our very hairs are numbered. No accident then that can befal our bodies is to be feared; thus He adds, Fear not, ye are better than many sparrows.
On 10:29
Or this, ye are better than many sparrows, teaches that the elect faithful are better than the multitude of the unbelieving, for the one fall to earth, the other fly to heaven.
On 10:32
This He says in conclusion, because it behoves them after being confirmed by such teaching, to have a confident freedom in confessing God.
On 10:32
This teaches us, that in what measure we have borne witness to Him upon earth, in the same shall we have Him to bear witness to us in heaven before the face of God the Father.
On 10:35
Mystically; A sword is the sharpest of all weapons, and thence it is the emblem of the right of authority, the impartiality of justice, the correction of offenders. The word of God, we may remember, is likened to a sword; (Eph. 6:17. Heb. 4:12.) so here the sword that is sent upon the earth is His preaching poured into the heart of man. The five inhabiting one house, whom He divides three against two, and two against three, we may explain thus; The three are the three parts of man, the body, the soul, and the will; for as the soul is bestowed in the body, so the will has power of using both in any way it chooses; and thence when a law is given it is given to the will. But this is only found in those who were first formed by God. By the sin and unbelief of the first parent, all the generations of men since have had sin for the father of their body, and unbelief for the mother of their soul. And as each man has his will within him, there are thus five in one house. When then we are renewed in the laver of baptism, by virtue of the word we are set apart from our original guilt, and severed, as it were, by the sword of God, from the lusts of this our father and mother, and thus there is great discord made in one house; the new man finding his foes within, he seeks with joy to live in newness of spirit; they which are derived from the old stock, lust to remain in their old pleasures.
On 10:37
For they who have esteemed domestic affection of relations higher than God, are unworthy to inherit good things to come.
On 10:38
Or; They that are Christ’s have crucified the body with its vices and lusts. (Gal. 5:24.) And he is unworthy of Christ who does not take up His cross, in which we suffer with Him, die with Him, are buried and rise again with Him, and follow his Lord, purposing to live in newness of spirit in this sacrament of the faith.
On 10:39
Thus the gain of life brings death, the loss of life brings salvation; for by the sacrifice of this short life we gain the reward of immortality.
On 10:40
These words shew that He has a Mediator’s office, and since He came from God, when He is received by us, through Him God is transfused into us; and by this disposition of grace to have received the Apostles is no other than to have received God; for Christ dwells in them, and God in Christ.
On 10:42
Or; Seeing beforehand that there would be many who would only glory in the name of Apostleship, but in their whole life and walk would be unworthy of it, He does not therefore deprive of its reward that service which might be rendered to them in belief of their religious life. For though they were the very least, that is, the greatest of sinners, yet even small offices of mercy shewn them, such as are denoted by the cup of cold water, should not be shewn in vain. For the honour is not done to a man that is a sinner, but to his title of disciple.
