First Reading — Isaiah 49:1-6
Athanasius of Alexandria
On 49:5
In respect of nature, [Christ] differs in nothing from us, though he precedes us in time, so long as we all consist and are created by the same hand.
Responsorial Psalm — Psalm 139:1b-3, 13-14ab, 14c-15
Clement of Rome
On 138:7–10
Since, therefore, all things are seen and heard, let us fear him and abandon the abominable lusts that spawn evil works, in order that we may be shielded by his mercy from the coming judgments. For where can any of us escape from his mighty hand? For the Scripture says somewhere, "Where shall I go, and where shall I be hidden from your presence? If I ascend to heaven, you are there; if I depart to the ends of the earth, there is your right hand; if I take my bed in the depths, there is your Spirit." Where, then, can one go, or where can one flee from him who embraces the universe?
Second Reading — Acts 13:22-26
John Chrysostom
On 13:22–23
"And when he had removed him, He raised up unto them David to be their king: to whom also He gave testimony, and said, I have found David the son of Jesse, a man after Mine own heart, which shall fulfil all My will. Of this man's seed hath God according to His promise raised unto Israel a Saviour, Jesus." This was no small thing that Christ should be from David.
Observe how he twines the thread of his discourse alternately from things present, from the prophets. Thus, "from this man's seed according to the promise" - the name of David was dear to them; well then, is it not a thing to be desired that a son of his, he says, should be their king? - then he adduces John: then again the prophets, where he says, "By condemning they fulfilled," and again, "All that was written:" then the Apostles as witnesses of the Resurrection: then David bearing witness. For neither the Old Testament proofs seemed so cogent when taken by themselves as they are in this way, nor yet the latter testimonies apart from the former: wherefore he makes them mutually confirm each other.
The Promise then, he says, the fathers received; ye, the reality. And observe, he nowhere mentions right deeds of theirs, but only benefits on God's part: "He chose: Exalted: Suffered their manners:" these are no matters of praise to them: "They asked, He gave." But David he does praise, and him only, because from him the Christ was to come. "I have found David, the son of Jesse, a man after Mine own heart, which shall fulfil all My will." Observe also; it is with praise that he says of him, "David after that he had served the will of God:" just as Peter - seeing it was then the beginning of the Gospel - making mention of him, said, "Let it be permitted me to speak freely of the patriarch David." Also, he does not say, Died, but, "was added to his fathers."
On 13:24–25
Then John bears witness to this: "When John had first preached before His coming the baptism of repentance to all the people of Israel. And as John fulfilled his course, he said, Whom think ye that I am? I am not He. But, behold, there cometh one after me, whose shoes of His feet I am not worthy to loose." And John too not merely bears witness to the fact, but does it in such sort that when men were bringing the glory to him, he declines it: for it is one thing not to affect an honor which nobody thinks of offering; and another, to reject it when all men are ready to give it, and not only to reject it, but to do so with such humility.
Then he adduces John: then again the prophets, where he says, "By condemning they fulfilled," and again, "All that was written:" then the Apostles as witnesses of the Resurrection: then David bearing witness. For neither the Old Testament proofs seemed so cogent when taken by themselves as they are in this way, nor yet the latter testimonies apart from the former: wherefore he makes them mutually confirm each other.
"Of this man's seed," etc. "When John," he says, "had first preached before His entry" - by entry he means the Incarnation - "the baptism of repentance to all the people of Israel." Thus also John, writing his Gospel, continually has recourse to him: for his name was much thought of in all parts of the world. And observe, he does not say it "Of this man's seed," etc. from himself, but brings John's testimony.
On 13:26–28
"Men and brethren, children of the stock of Abraham, and whosoever among you feareth God, to you is the word of this salvation sent. For they that dwell at Jerusalem, and their rulers, because they knew Him not, nor yet the voices of the prophets which are read every sabbath day, they have fulfilled them in condemning Him. And though they found no cause of death in Him, yet desired they Pilate that He should be slain."
On all occasions we find them making a great point of showing this, that the blessing is peculiarly theirs, that they may not flee from Christ, as thinking they had nothing to do with Him, because they had crucified Him. "Because they knew Him not," he says: so that the sin was one of ignorance. See how he gently makes an apology even on behalf of those crucifiers. And not only this: but he adds also, that thus it must needs be. And how so? "By condemning Him, they fulfilled the voices of the prophets."
"Men and brethren," etc. For since they were possessed by fear, as having slain Him, and conscience made them aliens, the Apostles discourse not with them as unto Christicides, neither as putting into their hands a good which was not theirs, but one peculiarly their own. "For they that dwell at Jerusalem, and their rulers:" as much as to say, not ye, but they: and again, apologizing even for those, "Because they knew Him not, and the voices of the Prophets which are read every sabbath day, in condemning Him, they fulfilled them." A great charge it is against them that they continually hearing heeded not. But no marvel: for what was said above concerning Egypt and the wilderness, was enough to show their ingratitude.
"Men and brethren, children of the stock of Abraham" - he also calls them after their father - "unto you was the word of this salvation sent." Here the expression, "Unto you," does not mean, Unto you Jews, but it gives them a right to sever themselves from those who dared that murder. And what he adds, shows this plainly. "For," he says, "they that dwell at Jerusalem, because they know Him not." And how, you will say, could they be ignorant, with John to tell them? What marvel, seeing they were so, with the prophets continually crying aloud to them? Then follows another charge: "And having found no cause of death in Him:" in which ignorance had nothing to do. For let us put the case, that they did not hold Him to be the Christ: why did they also kill Him? And "they desired of Pilate, he says, that He should be slain."
Gospel — Luke 1:57-66, 80
Origen
On 1:59
(non occ.) Zacharias is by interpretation “remembering God,” but John signifies “pointing to.” Now “memory” relates to something absent, “pointing to,” to something present. But John was not about to set forth the memory of God as absent, but with his finger to point him out as present, saying, Behold the Lamb of God.
On 1:67
Now Zacharias being filled with the Holy Spirit utters two prophecies, the first relating to Christ, the second to John. And this is plainly proved by those words in which he speaks of the Saviour as present and already going about in the world, saying, Blessed be the Lord God of Israel, for he hath visited, &c.
On 1:69
Because Christ was born of the seed of David, according to the flesh, it is said, A horn of salvation to us in the house of his servant David; as it has also elsewhere been said, A vineyard hath been planted in a horn, (Is. 5:1.) i. e. in Jesus Christ.
On 1:71
Let us not suppose that this refers to our bodily enemies, but our ghostly. For the Lord Jesus came mighty in battle (Ps. 24:8) to destroy all our enemies, that He might deliver us from their snares and temptation.
On 1:72
I think that at the coming of our Lord and Saviour Jesus Christ, both Abraham, Isaac, and Jacob, were partakers of His mercy. For it is not to be believed, that they who had before seen His day, and were glad, should afterwards derive no advantage from His coming, since it is written, Having made peace through the blood of his Cross, whether in earth or in heaven. (Coloss. 1:20.)
On 1:74
Or in another way; Frequently are men delivered from the hands of the enemy, but not without fear. For when fear and peril have gone before, and a man is then plucked from the enemies’ hand, he is delivered indeed, but not without fear. Therefore said he, that the coming of Christ caused us to be snatched from the enemies’ hands without fear. For we suffered not from their evil designs, but He suddenly parting us from them, hath led us out to our own allotted resting place.
On 1:76
The reason I suppose that Zacharias hastened to speak to his son, was because he knew that John was shortly about to be a sojourner in the wilderness, and that he himself should see him no more.
On 1:80
Or he increased in spirit, remaining not in the same measure in which he had begun, but the Spirit was ever growing in him. His will ever tending to better things, was making its own advances, and his mind ever contemplating something more divine, while his memory was exercising itself, that it might lay up more and more things in its treasury, and more firmly retain them. But he adds, And he waxed strong. For human nature is weak, as we learn, the flesh is weak. (Matt. 26:41.) It must therefore be made strong by the Spirit, for the Spirit is ready. Many wax strong in the flesh, but the wrestler of God must be strengthened by the Spirit that he may crush the wisdom of the flesh. He retires therefore to escape the noise of cities, and the thronging of the people. For it follows, And he was in the deserts. Where the air is purer, the sky more clear, and God a closer friend, that as the time had not yet arrived for his baptism and preaching, he might have leisure for praying, and might hold converse with the angels, calling upon God and fearing Him, saying, Behold, here am I.
