First Reading — Romans 5:12, 15b, 17-19, 20b-21
Irenaeus
On 5:14
For it was incumbent upon the Mediator between God and men, by His relationship to both, to bring both to friendship and concord, and present man to God, while He revealed God to man. For, in what way could we be partaken of the adoption of sons, unless we had received from Him through the Son that fellowship which refers to Himself, unless His Word, having been made flesh, had entered into communion with us? Wherefore also He passed through every stage of life, restoring to all communion with God. Those, therefore, who assert that He appeared putatively, and was neither born in the flesh nor truly made man, are as yet under the old condemnation, holding out patronage to sin; for, by their showing, death has not been vanquished, which "reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression."
But the law coming, which was given by Moses, and testifying of sin that it is a sinner, did truly take away his (death's) kingdom, showing that he was no king, but a robber; and it revealed him as a murderer. It laid, however, a weighty burden upon man, who had sin in himself, showing that he was liable to death. For as the law was spiritual, it merely made sin to stand out in relief, but did not destroy it. For sin had no dominion over the spirit, but over man. For it behoved Him who was to destroy sin, and redeem man under the power of death, that He should Himself be made that very same thing which he was, that is, man; who had been drawn by sin into bondage, but was held by death, so that sin should be destroyed by man, and man should go forth from death.
Wherefore Luke points out that the pedigree which traces the generation of our Lord back to Adam contains seventy-two generations, connecting the end with the beginning, and implying that it is He who has summed up in Himself all nations dispersed from Adam downwards, and all languages and generations of men, together with Adam himself. Hence also was Adam himself termed by Paul "the figure of Him that was to come," because the Word, the Maker of all things, had formed beforehand for Himself the future dispensation of the human race, connected with the Son of God; God having predestined that the first man should be of an animal nature, with this view, that he might be saved by the spiritual One. For inasmuch as He had a pre-existence as a saving Being, it was necessary that what might be saved should also be called into existence, in order that the Being who saves should not exist in vain.
On 5:17
Concurring with these statements, Paul, speaking to the Romans, declares: "Much more they who receive abundance of grace and righteousness for [eternal] life, shall reign by one, Christ Jesus." It follows from this, that he knew nothing of that Christ who flew away from Jesus; nor did he of the Saviour above, whom they hold to be impassible. For if, in truth, the one suffered, and the other remained incapable of suffering, and the one was born, but the other descended upon him who was born, and left him gain, it is not one, but two, that are shown forth.
On 5:19
For as by the disobedience of the one man who was originally moulded from virgin soil, the many were made sinners, and forfeited life; so was it necessary that, by the obedience of one man, who was originally born from a virgin, many should be justified and receive salvation. Thus, then, was the Word of God made man, as also Moses says: "God, true are His works." But if, not having been made flesh, He did appear as if flesh, His work was not a true one. But what He did appear, that He also was: God recapitulated in Himself the ancient formation of man, that He might kill sin, deprive death of its power, and vivify man; and therefore His works are true.
For as by one man's disobedience sin entered, and death obtained [a place] through sin; so also by the obedience of one man, righteousness having been introduced, shall cause life to fructify in those persons who in times past were dead. And as the protoplast himself Adam, had his substance from untilled and as yet virgin soil ("for God had not yet sent rain, and man had not tilled the ground"), and was formed by the hand of God, that is, by the Word of God, for "all things were made by Him," and the Lord took dust from the earth and formed man; so did He who is the Word, recapitulating Adam in Himself, rightly receive a birth, enabling Him to gather up Adam [into Himself], from Mary, who was as yet a virgin. If, then, the first Adam had a man for his father, and was born of human seed, it were reasonable to say that the second Adam was begotten of Joseph. But if the former was taken from the dust, and God was his Maker, it was incumbent that the latter also, making a recapitulation in Himself, should be formed as man by God, to have an analogy with the former as respects His origin. Why, then, did not God again take dust, but wrought so that the formation should be made of Mary? It was that there might not be another formation called into being, nor any other which should [require to] be saved, but that the very same formation should be summed up [in Christ as had existed in Adam], the analogy having been preserved.
On 5:20
All therefore speak falsely who disallow his (Adam's) salvation, shutting themselves out from life for ever, in that they do not believe that the sheep which had perished has been found. For if it has not been found, the whole human race is still held in a state of perdition. False, therefore, is that, man who first started this idea, or rather, this ignorance and blindness-Tatian. As I have already indicated, this man entangled himself with all the heretics. This dogma, however, has been invented by himself, in order that, by introducing something new, independently of the rest, and by speaking vanity, he might acquire for himself hearers void of faith, affecting to be esteemed a teacher, and endeavouring from time to time to employ sayings of this kind often [made use of] by Paul: "In Adam we all die;" ignorant, however, that "where sin abounded, grace did much more abound." Since this, then, has been clearly shown, let all his disciples be put to shame, and let them wrangle about Adam, as if some great gain were to accrue to them if he be not saved; when they profit nothing more [by that], even as the serpent also did not profit when persuading man [to sin], except to this effect, that he proved him a transgressor, obtaining man as the first-fruits of his own apostasy. But he did not know God's power. Thus also do those who disallow Adam's salvation gain nothing, except this, that they render themselves heretics and apostates from the truth, and show themselves patrons of the serpent and of death.
Responsorial Psalm — Psalm 40:7-8a, 8b-9, 10, 17
Athanasius of Alexandria
On 39:7
Here the psalmist introduces the person of Christ, who says, By the will of the Father he came and completed the things that are written concerning him in the law and the prophets. And he declared his righteousness in a great church, which is in all peoples and is more excellent than that of the law.
On 39:11
[At this point in the psalm] he introduces the persons of those who believed from Israel; for he confesses to God that he did not remove his mercy from it but then and now saved and supported them.
