First Reading — Acts 13:14, 43-52
Ignatius of Antioch
On 13:48
It is absurd to speak of Jesus Christ with the tongue, and to cherish in the mind a Judaism which has now come to an end. For where there is Christianity there cannot be Judaism. For Christ is one, in whom every nation that believes, and every tongue that confesses, is gathered unto God. And those that were of a stony heart have become the children of Abraham, the friend of God; and in his seed all those have been blessed who were ordained to eternal life in Christ.
Responsorial Psalm — Psalm 100:1-2, 3, 5
Augustine of Hippo
On 99:1
"Jubilate," therefore, "unto the Lord, all you lands" [Psalm 100:1]. This Psalm gives this exhortation to us, that we jubilate unto the Lord. Nor does it, as it were, exhort one particular corner of the earth, or one habitation or congregation of men; but since it is aware that it has sown blessings on every side, on every side it does exact jubilance. Does all the earth at this moment hear my voice? And yet the whole earth has heard this voice. All the earth is already jubilant in the Lord; and what is not as yet jubilant, will be so. For blessing, extending on every side, when the Church was commencing to spread from Jerusalem throughout all nations, [Luke 24:47] everywhere overturns ungodliness, and everywhere builds up piety: the good are mingled with the wicked throughout all lands. Every land is full of the discontented murmurs of the wicked, and of the jubilance of the good. What then is it, "to jubilate"? For the title of the present Psalm especially makes us give good heed to this word, for it is entitled, "A Psalm of confession." What means, to jubilate with confession? It is the sentiment thus expressed in another Psalm: "Blessed is the people that understands jubilance." Surely that which being understood makes blessed is something great. May therefore the Lord our God, who makes men blessed, grant me to understand what to say, and grant you to understand what ye hear: "Blessed is the people that understands jubilance." Let us therefore run unto this blessing, let us understand jubilance, let us not pour it forth without understanding. Of what use is it to be jubilant and obey this Psalm, when it says, "Jubilate unto the Lord, all you lands," and not to understand what jubilance is, so that our voice only may be jubilant, our heart not so? For the understanding is the utterance of the heart.
On 99:2
"O serve the Lord with gladness" (ver. 2): he addresseth you, whoever ye are who endure all things in love, and rejoice in hope. "Serve the Lord," not in the bitterness of murmuring, but in the "gladness of love." "Come before His presence with rejoicing." It is easy to rejoice outwardly: rejoice before the presence of God. Let not the tongue be too joyful: let the conscience be joyful. "Come before His presence with a song."
On 99:3
"Enter into His gates with confession" (ver. 3). At the gates is the beginning: begin with confession. Thence is the Psalm entitled, "A Psalm of Confession:" there be joyful. Confess that ye were not made by yourselves, praise Him by whom ye were made. Let thy good come from Him, in departing from whom thou hast caused thine evil. "Enter into His gates with confession." Let the flock enter into the gates: let it not remain outside, a prey for wolves. And how is it to enter? "With confession." Let the gate, that is, the commencement for thee, be confession. Whence it is said in another Psalm, "Begin unto the Lord with confession." What he there calleth "Begin," here he calleth "Gates." "Enter into His gates in confession." What? And when we have entered, shall we not still confess? Always confess Him: thou hast always what to confess for. It is hard in this life for a man to be so far changed, that no cause for censure be discoverable in him: thou must needs blame thyself, lest He who shall condemn blame thee. Therefore even when thou hast entered His courts, then also confess. When will there be no longer confession of sins? In that rest, in that likeness to the Angels. But consider what I have said: there will there be no confession of sins. I said not, there will be no confession: for there will be confession of praise. Thou wilt ever confess, that He is God, thou a creature; that He is thy Protector, thyself protected. In Him thou shalt be as it were hid. "Go into His courts with hymns; and confess unto Him." Confess in the gates; and when ye have entered the courts, confess with hymns. Hymn are praises. Blame thyself, when thou art entering; when thou hast entered, praise Him. "Open me the gates of righteousness," he saith in another Psalm, "that I may go into them, and confess unto the Lord." Did he say, when I have entered, I will no longer confess? Even after his entrance, he will confess. For what sins did our Lord Jesus Christ confess, when He said, "I confess unto Thee, O Father"? He confessed in praising Him, not in accusing Himself. "Speak good of His Name."
On 99:3
And what is this? I asked the earth; and it answered, "I am not He;" and whatsoever are therein made the same confession. I asked the sea and the deeps, and the creeping things that lived, and they replied, "We are not thy God, seek higher than we." I asked the breezy air, and the universal air with its inhabitants answered, "Anaximenes was deceived, I am not God." I asked the heavens, the sun, moon, and stars: "Neither," say they, "are we the God whom thou seekest." And I answered unto all these things which stand about the door of my flesh, "Ye have told me concerning my God, that ye are not He; tell me something about Him." And with a loud voice they exclaimed, "He made us." My questioning was my observing of them; and their beauty was their reply.
On 99:4
"For the Lord is pleasant" [Psalm 100:4]. Think not that you faint in praising Him. Your praise of Him is like food: the more ye praise Him, the more ye acquire strength, and He whom you praise becomes the more sweet.
On 99:5
"His mercy is everlasting." For He will not cease to be merciful, after He has freed you: it belongs to His mercy to protect you even unto eternal life. "His mercy," therefore, "is to everlasting: and His Truth from generation to generation" [Psalm 100:5]. Understand by "from generation to generation," either every generation, or in two generations, the one earthly, the other heavenly. Here there is one generation which produces mortals; another which makes such as are everlasting. His Truth is both here, and there. Imagine not that His truth is not here, if His truth were not here, he would not say in another Psalm: "Truth is risen out of the earth;" nor would Truth Itself say, Lo, I am with you always, even unto the end of the world. [Matthew 28:20]
Second Reading — Revelation 7:9, 14b-17
Tertullian
On 7:14
Then to every conqueror the Spirit promises now the tree of life and exemption from the second death; now the hidden manna, with the stone of glistening whiteness, and the name unknown (to every man except those who receive it); now power to rule with a rod of iron and the brightness of the morning star; now the being clothed in white raiment, and not having the name blotted out of the book of life, and being made in the temple of God a pillar with the inscription on it of the name of God and of the Lord, and of the heavenly Jerusalem; now a sitting with the Lord on his throne, which once was persistently refused to the sons of Zebedee. Who, pray, are these so blessed conquerors, but martyrs in the strict sense of the word? For indeed theirs are the victories whose also are the fights; theirs, however, are the fights whose also is the blood. But the souls of the martyrs both peacefully rest in the meantime under the altar and support their patience by the assured hope of revenge; and, clothed in their robes, wear the dazzling halo of brightness, until others also may fully share in their glory. For yet again a countless throng are revealed, clothed in white and distinguished by palms of victory, celebrating their triumph doubtless over antichrist, since one of the elders says, "These are they who come out of that great tribulation, and have washed their robes, and made them white in the blood of the Lamb." For the flesh is the clothing of the soul. The uncleanness, indeed, is washed away by baptism, but the stains are changed into dazzling whiteness by martyrdom.

On 7:17
"Everlasting joy," says Isaiah, "shall be upon their heads." Well, there is nothing eternal until after the resurrection. "And sorrow and sighing," he continues, "shall flee away." The angel echoes the same to John: "And God shall wipe away all tears from their eyes"; from the same eyes indeed that had formerly wept and that might weep again, if the lovingkindness of God did not dry up every fountain of tears. And again: "God shall wipe away all tears from their eyes; and there shall be no more death," and therefore no more corruption, it being chased away by incorruption, even as death is by immortality. If sorrow, and mourning, and sighing, and death itself assail us from the afflictions both of soul and body, how shall they be removed, except by the cessation of their causes, that is to say, the afflictions of flesh and soul? Where will you find adversities in the presence of God? Where, incursions of an enemy in the bosom of Christ? Where attacks of the devil in the face of the Holy Spirit, now that the devil himself and his angels are "cast into the lake of fire."
On 7:17
The angel echoes the same to John: "And God shall wipe away all tears from their eyes; " from the same eyes indeed which had formerly wept, and which might weep again, if the loving-kindness of God did not dry up every fountain of tears.
Gospel — John 10:27-30
Hilary of Poitiers
On 10:29
(de Trin. vii. c. 22) This is the speech of conscious power. Yet to shew, that though of the Divine nature He hath His nativity from God, He adds, My Father which gave Me them is greater than all. He does not conceal His birth from the Father, but proclaims it. For that which He received from the Father, He received in that He was born from Him. He received it in the birth itself, not after it; though He was born when He received it.
On 10:29
(vii. de Trin. c. 22) The hand of the Son is spoken of as the hand of the Father, to let thee see, by a bodily representation, that both have the same nature, that the nature and virtue of the Father is in the Son also.
