First Reading — 1 John 3:11-21
Clement of Alexandria
On 3:15
"Every one who hates his brother is a murderer." For in him through unbelief Christ dies. Rightly, therefore, he continues, "And you know that no murderer and unbeliever has eternal life abiding in him." For the living Christ abides in the believing soul.
On 3:15
And if we owe our lives to the brethren, and have made such a mutual compact with the Saviour, why should we any more hoard and shut up worldly goods, which are beggarly, foreign to us and transitory? Shall we shut up from each other what after a little shall be the property of the fire? Divinely and weightily John says, "He that loveth not his brother is a murderer," the seed of Cain, a nursling of the devil. He has not God's compassion. He has no hope of better things. He is sterile; he is barren; he is not a branch of the ever-living supercelestial vine. He is cut off; he waits the perpetual fire.
On 3:16
"For He Himself laid down His life for us;" that is, for those who believe; that is, for the apostles. If then He laid down His life for the apostles, he means His apostles themselves: us if he said, We, I say, the apostles, for whom He laid down His life, "ought to lay down our lives for the brethren;" for the salvation of their neighbours was the glory of the apostles.
On 3:18
"Little children, let us not love in word, or in tongue," says John, teaching them to be perfect, "but in deed and in truth; hereby shall we know that we are of the truth." And if "God be love," piety also is love: "there is no fear in love; but perfect love casteth out fear." "This is the love of God, that we keep His commandments." And again, to him who desires to become a Gnostic, it is written, "But be thou an example of the believers, in word, in conversation, in love, in faith, in purity." For perfection in faith differs, I think, from ordinary faith.
On 3:20
He says, "For God is greater than our heart;" that is, the virtue of God [is greater] than conscience, which will follow the soul. Wherefore he continues, and says, "and knoweth all things."
Responsorial Psalm — Psalm 100:1b-2, 3, 4, 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]
Gospel — John 1:43-51
John Chrysostom
On 1:43
(Hom. xix) After gaining these disciples, Christ proceeded to convert others, viz. Philip and Nathanael: The day following, Jesus would go forth into Galilee.
On 1:43
(Hom. xx. 1) Observe, He did not call them, before some had of their own accord joined Him: for had He invited them, before any had joined Him, perhaps they would have started back: but now having determined to follow of their own free choice, they remain firm ever after. He calls Philip, however, because he would be known to him, from living in Galilee. But what made Philip follow Christ? Andrew heard from John the Baptist, and Peter from Andrew; he had heard from no one; and yet on Christ saying, Follow Me, was persuaded instantly. It is not improbable that Philip may have heard John: and yet it may have been the mere voice of Christ which produced this effect.
On 1:43
(Hom. xx. 1) The power of Christ appears by His gathering fruit out of a barren country. For from that Galilee, out of which there ariseth no prophet, He takes His most distinguished disciples.
On 1:45
(Hom. xx. 1) Philip is not persuaded himself, but begins preaching to others: Philip findeth Nathanael, and saith unto him, We have found Him of whom Moses in the Law, and the Prophets, did write, Jesus of Nazareth, the Son of Joseph. See how zealous he is, and how constantly he is meditating on the books of Moses, and looking for Christ’s coming. That Christ was coming he had known before; but he did not know that this was the Christ, of whom Moses and the Prophets did write: He says this to give credibility to his preaching, and to shew his zeal for the Law and the Prophets, and how that he had examined them attentively. Be not disturbed at his calling our Lord the Son of Joseph; this was what He was supposed to be.
On 1:46
(Hom. xx. 1, 2) Nathanael knew from the Scriptures, that Christ was to come from Bethlehem, according to the prophecy of Micah, And thou, Bethlehem, in the land of Judah,—out of thee shall come a Governor, that shall rule my people Israel. (Micah 5:2) On hearing of Nazareth, then, he doubted, and was not able to reconcile Philip’s tidings with prophecy. For the Prophets call Him a Nazarene, only in reference to His education and mode of life. Observe, however, the discretion and gentleness with which he communicates his doubts. He does not say, Thou deceivest me, Philip; but simply asks the question, Can any good thing come out of Nazareth? Philip too in turn is equally discrete. He is not confounded by the question, but dwells upon it, and lingers in the hope of bringing him to Christ: Philip saith unto him, Come and see. He takes him to Christ, knowing that when he had once tasted of His words and doctrine, he will make no more resistance.
On 1:47
(Hom. xix) Nathanael, in difficulty as to Christ coming out of Nazareth, shewed the care with which he had read the Scriptures: his not rejecting the tidings when brought him, shewed his strong desire for Christ’s coming. He thought that Philip might be mistaken as to the place. It follows, Jesus saw Nathanael coming to Him, and saith of him, Behold an Israelite indeed, in whom is no guile! There was no fault to be found with him, though he had spoken like one who did not believe, because he was more deeply read in the Prophets than Philip. He calls him guileless, because he had said nothing to gain favour, or gratify malice.
On 1:47
(Hom. xxi. [al. xx.] 1) Many when they read this passage, are perplexed at finding that, whereas Peter was pronounced blessed for having, after our Lord’s miracles and teaching, confessed Him to be the Son of God, Nathanael, who makes the same confession before, has no such benediction. The reason is this. Peter and Nathanael both used the same words, but not in the same meaning. Peter confessed our Lord to be the Son of God, in the sense of very God; the latter in the sense of mere man; for after saying, Thou art the Son of God, he adds, Thou art the King of Israel; whereas the Son of God was not the King of Israel only, but of the whole world. This is manifest from what follows. For in the case of Peter Christ added nothing, but, as if his faith were perfect, said, that he would build the Church upon his confession; whereas Nathanael, as if his confession were very deficient, is led up to higher things: Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? Thou shalt see greater things than these. As if He said, What I have just said has appeared a great matter to thee, and thou hast confessed Me to be King of Israel; what wilt thou say when thou seest greater things than these? What that greater thing is He proceeds to shew: And He saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man. See how He raises him from earth for a while, and forces him to think that Christ is not a mere man: for how could He be a mere man, whom angels ministered to? It was, as it were, saying, that He was Lord of the Angels; for He must be the King’s own Son, on whom the servants of the King descended and ascended; descended at His crucifixion, ascended at His resurrection and ascension. Angels too before this came and ministered unto Him, and angels brought the glad tidings of His birth. Our Lord made the present a proof of the future. After the powers He had already shewn, Nathanael would readily believe that much more would follow.
On 1:48
(Hom. xx) He asks as man, Jesus answers as God: Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee: not having beheld him as man, but as God discerning him from above. I saw thee, He says, that is, the character of thy life, when thou wast under the fig tree: where the two, Philip and Nathanael, had been talking together alone, nobody seeing them; and on this account it is said, that on seeing him a long way off, He said, Behold an Israelite indeed; whence it appears that this speech was before Philip came near, so that no suspicion could attach to Christ’s testimony. Christ would not say, I am not of Nazareth, as Philip told you, but of Bethlehem; in order to avoid an argument: (ἀμφισβητήσιμον λόγον.) and because it would not have been sufficient proof, had He mentioned it, of His being the Christ. He preferred rather proving this by His having been present at their conversation.
On 1:49
(Hom. xx) That our Lord then had this knowledge, had penetrated into his mind, had not blamed but praised his hesitation, proved to Nathanael that He was the true Christ: Nathanael answered and saith unto Him, Rabbi, Thou art the Son of God, Thou art the King of Israel: as if he said, Thou art He who was expected, thou art He who was sought for. Sure proof being obtained, he proceeds to make confession; herein shewing his devotion, as his former hesitation had shewn his diligence.
