First Reading — 1 John 2:29-3:6
Ignatius of Antioch
On 2:22
Whosoever, therefore, declares that there is but one God, only so as to take away the divinity of Christ, is a devil, and an enemy of all righteousness. He also that confesseth Christ, yet not as the Son of the Maker of the world, but of some other unknown being, different from Him whom the law and the prophets have proclaimed, this man is an instrument of the devil. And he that rejects the incarnation, and is ashamed of the cross for which I am in bonds, this man is antichrist. Moreover, he who affirms Christ to be a mere man is accursed, according to the [declaration of the] prophet, since he puts not his trust in God, but in man. Wherefore also he is unfruitful, like the wild myrtle-tree.
Responsorial Psalm — Psalm 98:1, 3cd-4, 5-6
Eusebius of Caesarea
On 97:1–2
Along with my prayers I now add book 10 to the Church History and dedicate it to you, my most consecrated Paulinus, and blazon you as the seal of the whole work. It is appropriate that in a perfect number I shall here provide a completed account in celebration of the restoration of the churches, in obedience to the divine Spirit who urges us:
Sing to the Lord a new song, for he has done marvelous things;
His right and his holy arm have wrought salvation for him.
The Lord has made known his salvation:
His righteousness he has revealed in the sight of the heathen.
Accordingly, let me now sing the new song, since after those grim and horrifying scenes and narratives, I was now privileged to see and to celebrate what many righteous people and martyrs of God before me desired to see but did not see and to hear but did not hear. But they hurried on to far better things in the heavens, caught up into a paradise of divine bliss, while I, admitting that even the present circumstances are more than I deserve, have been totally astonished at the magnitude of grace he has conferred and offer him my total awe and worship, confirming the truth of the prophecies that declare:
Come and behold the works of the Lord,
What wonders he has wrought on the earth,
Making wars to cease to the ends of the world.
He will break the bow and shatter the spear,
And the shields he will burn with fire.
Rejoicing that all this has been clearly fulfilled, let me proceed with my narrative.
Gospel — John 1:29-34
Origen
On 1:29
(tom. vi. c. 30) After this testimony, Jesus is seen coming to John, not only persevering in his confession, but also advanced in goodness: as is intimated by the second day. Wherefore it is said, The next day John seeth Jesus coming to him. Long before this, the Mother of Jesus, as soon as she had conceived Him, went to see the mother of John then pregnant; and as soon as the sound of Mary’s salutation reached the ears of Elisabeth, John leaped in the womb: but now the Baptist himself after his testimony seeth Jesus coming. Men are first prepared by hearing from others, and then see with their own eyes. The example of Mary going to see Elisabeth her inferior, and the Son of God going to see the Baptist, should teach us modesty and fervent charity to our inferiors. What place the Saviour came from when He came to the Baptist we are not told here; but we find it in Matthew, Then cometh Jesus from Galilee to Jordan unto John to be baptized of him. (Matt. 3:13)
On 1:29
(tom. vi. c. 32. et seq.) But whereas five kinds of animals are offered in the temple, three beasts of the field, a calf, a sheep, and a goat; and two fowls of the air, a turtle dove and a pigeon; and of the sheep kind three are introduced, the ram, the ewe, the lamb; of these three he mentions only the lamb; the lamb, as we know, being offered in the daily sacrifice, one in the morning, and one in the evening. But what other daily offering can there be, that can be meant to be offered by a reasonable nature, except the perfect Word, typically called the Lamb? This sacrifice, which is offered up as soon as the soul begins to be enlightened, shall be accounted as a morning sacrifice, referring to the frequent exercise of the mind in divine things; for the soul cannot continually apply to the highest objects because of its union with an earthly and gross body. By this Word too, Which is Christ the Lamb, we shall be able to reason on many things, and shall in a manner attain to Him in the evening, while engaged with things of the bodyt. But He Who offered the lamb for a sacrifice, was God hid in human form, the great Priest, He who saith below, No man taketh it (My life) from Me, but I lay it down of Myself: (John 10:18) whence this name, the Lamb of God: for He carrying our sorrows, (Isaiah 53:4. 1 Pet. 2:24.) and taking away the sins of the whole world, hath undergone death, as it were baptism. (Luke 12:50.) For God suffers no fault to pass uncorrected; but punishes it by the sharpest discipline.
On 1:29
(tom. vi. c. 36) As there was a connexion between the other sacrifices of the law, and the daily sacrifice of the lamb, in the same way the sacrifice of this Lamb has its reflexion in the pouring out of the blood of the Martyrs, by whose patience, confession, and zeal for goodness, the machinations of the ungodly are frustrated.
