First Reading — Revelation 21:9b-14
Tertullian
On 21:10
This both Ezekiel had knowledge of and the Apostle John beheld. And the word of the new prophecy which is a part of our belief, attests how it foretold that there would be for a sign a picture of this very city exhibited.
Responsorial Psalm — Psalm 145:10-11, 12-13, 17-18
Gregory of Nyssa
On 144:16
A person, then, who remains the same and yet babbles to himself about the change for the better he has undergone in baptism should attend to what Paul says: "If anyone thinks he is something when he is nothing, he deceives himself." For you are not what you have not become; whereas the gospel says of the regenerate that "he gave all those who received him the power to become God's children." Now the child born of someone certainly shares his parent's nature. If, then, you have received God and become his child, let your way of life testify to the God within you; make it clear who your Father is! The marks by which we recognize God are the very ones by which a son of his must show his relation to him: "he opens his hand and fills everything living with joy"; "he overlooks iniquity"; "he relents of his evil purpose";29 "the Lord is kind to all and is not angry with us every day"; "God is straightforward, and there is no unrighteousness in him"31—and the similar sayings scattered through Scripture for our instruction. If you are like this, you have genuinely become a child of God. But if you persist in displaying the marks of evil, it is useless to babble to yourself about the birth from above. Prophecy will tell you, "You are a son of humankind, not a son of the most High. You love vanity and seek lies. You fail to realize that the only way one is magnified is by becoming holy."
Gospel — John 1:45-51
John Chrysostom
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.
