15 But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many.
[AD 253] Origen of Alexandria on Romans 5:15
It makes no difference that Paul said [in verse 12] that sin spread to all, whereas here he says that the grace and gift of God have abounded for many. In Paul’s usage, all and many are almost synonymous.… Yet Paul refrains from saying that all will benefit from the free grace of God, because if men had the assurance that they would be saved, they would not fear God and turn away from evil.[In this verse] Paul starts to explain how Adam may be regarded as a type of Christ. Any close similarity between them is obviously absurd, which is why he insists that “the free gift is not like the trespass.” … The judgment on Adam was that through his one sin condemnation came to all men. But in sharp contrast to this, through Christ justification is given to all for the many sins in which the entire human race is bound up.

[AD 384] Ambrosiaster on Romans 5:15
Paul said that Adam was a type of Christ, but in order to assure us that they were not alike in substance, he says that the gift is not like the trespass. The only similarity between them is that just as one man sinned, so one man put things right.If by the trespass of one man many have died by imitating his transgression, how much more has the grace of God and his gift abounded in those who flee to him for refuge! For there are more who have received grace than who have died because of Adam’s trespass. From this it is clear that Paul was not talking about ordinary death, which is common to us all, since everybody dies but not everybody receives grace. Death does not reign in everyone. It only reigns in those who have died because of the sin of Adam, who have sinned by a transgression like his. Paul is talking only about these when he says that although many have died because of Adam’s sin, many more have received grace.… For both to those who sinned in a way similar to Adam and to those who did not sin in that way but who were nevertheless confined to hell because of God’s judgment on Adam’s sin, the grace of God has abounded by the descent of the Savior to hell, granting pardon to all and leading them up to heaven in triumph.

[AD 390] Diodorus of Tarsus on Romans 5:15
At first sight it may seem that this verse contradicts what Paul said [in verse 12] above, for there he spoke of death having come to all humanity, whereas here he says only that many have died. In fact there is no contradiction, because death, although it came upon all because we have all sinned, came only to test and to try everyone. Death does not destroy all sinners automatically but only those who persist in their sins. By saying that “many died” Paul shows merely that many turned out to be unrepentant in their sins.

[AD 407] John Chrysostom on Romans 5:15
For what he says is somewhat of this kind. If sin had so extensive effects, and the sin of one man too; how can grace, and that the grace of God, not the Father only, but also the Son, do otherwise than be the more abundant of the two? For the latter is far the more reasonable supposition. For that one man should be punished on account of another does not seem to be much in accordance with reason. But for one to be saved on account of another is at once more suitable and more reasonable. If then the former took place, much more may the latter. Hence he has shown from these grounds the likelihood and reasonableness of it. For when the former had been made good, this would then be readily admitted. But that it is even necessarily so, he makes good from what follows. How then does he make it good?

[AD 407] John Chrysostom on Romans 5:15
What Paul is saying here seems to be something like this. If sin, and the sin of a single man moreover, had such a big effect, how is it that grace, and that the grace of God—not of the Father only but also of the Son—would not have an even greater effect? That one man should be punished on account of another does not seem reasonable, but that one man should be saved on account of another is both more suitable and more reasonable. So if it is true that the former happened, much more should the latter have happened as well!

[AD 418] Pelagius on Romans 5:15
The gift is not like the trespass, because one must not give equal value to the type as to the original. Righteousness had more power to bring to life than sin had to put to death. Adam killed only himself and his descendants, whereas Christ freed both those who were then in the body and also succeeding generations. Those who oppose the idea of the transmission of sin try to attack it as follows: “If Adam’s sin harmed even those who were not sinners, then Christ’s righteousness must help even those who are not believers. For Paul says that people are saved through Christ in the same way or to an even greater degree than they had previously perished through Adam.” Secondly, they say: “If baptism washes away that ancient sin, those who are born of two baptized parents should not have that sin, for they could not have passed on to their children what they did not possess themselves. Besides, if the soul does not exist by transmission, but only the flesh, then only the flesh carries the transmission of sin and it alone deserves punishment.” Declaring it to be unjust that a soul which is born today, not from the lump of Adam, bears so ancient a sin belonging to another, these people say that on no account should it be accepted that God, who forgives a man his own sins, imputes to him the sins of someone else.

[AD 430] Augustine of Hippo on Romans 5:15
The gift excels in two ways: first, because grace abounds much more in that it bestows eternal life even though death reigns in the temporal sphere because of the death of Adam, and second, because by the condemnation of one sin the death of many came about through Adam, whereas by the forgiveness of many sins through our Lord Jesus Christ grace has been given for eternal life.

[AD 458] Theodoret of Cyrus on Romans 5:15
Paul calls Jesus a man in this passage in order to underline the parallel with Adam, for just as death came through one man, so the cure for death came through one man as well.

[AD 990] Oecumenius on Romans 5:15
Christ’s obedience was greater than Adam’s disobedience in the following sense. Death, which originated with the sin of Adam, had our cooperation in the sins which we all committed, and so it was able to gain control over us. For if men had remained free of all wrongdoing, death would not have been in control. But the grace of Christ has come to us all without our cooperation and shows that the grace of the resurrection is such that not only believers, who glory in their faith, will be resurrected, but also unbelievers, both Jews and Greeks. Something which works in us against our will is therefore obviously greater than something which works in us with our cooperation.

[AD 1274] Thomas Aquinas on Romans 5:15
After discussing the entry of sin into this world, the Apostle treats of the history of grace, which abolishes sin. And concerning this he does two things. First, he shows how the grace of Christ removed sin, which entered the world through one man; secondly, how it removed sin, which superabounded with the coming of the Law [v. 20; n. 448]. 223 In showing how Christ’s grace removed the sin introduced into the world by Adam, he compares Christ’s grace to Adam’s sin, stating that Christ’s grace can accomplish more good than Adam’s sin accomplishes evil. And concerning this he does two things. First, he compares the causes, namely, Christ’s grace, with Adam’s sin; secondly, he compares their effects [v. 16; n. 435]. In regard to the first he does two things: first, he gives the comparison; secondly, he clarifies it [v. 15b; n. 432]. 431. First, therefore, he says: It has been stated that Adam is the type of the one who was to come, but not like the trespass is the free gift. As if to say: the efficacy of Adam’s trespass must not be considered the equal of Christ’s gift. The reason is that sin came from the weakness of the human will, but grace comes from the immensity of the divine goodness, which excels the human will, especially in its weakness. Therefore, the power of grace exceeds every sin; consequently, David said: "Have mercy on me, O God, according to thy abundant mercy" (Ps 51:1). For this reason Cain’s attitude is justly reproved: "My sin is too great to merit pardon" (Gen 4:13). 432. Then (v.15b) he explains what he had said, namely, that the gift of grace exceeds Adam’s trespass, saying, if through one man’s trespass, namely, Adam’s, many died, i.e., if sin and death passed on to many others, because it passed on to all who sinned in him, much more have the grace of God and the free gift, where the "and" serves to explicate. Or, grace of God refers to the remission of sin as above (3:24): "Justified by his grace as a gift"; but gift refers to the blessings over and above the remission of sins, as 224 in Ps 67 (v.19): "The Lord gave gifts to men." Much more, I say, have the grace and gifts abounded for many. For the more potent something is, the more it can extend to a greater number. But the fact of death, which was Adam’s sin, extended to many. Hence, he says significantly that by the trespass of one many have died. For death is the argument for original sin, as stated above, for God said to Adam: "In the day that you eat of it, you shall die" (Gen 2:17). God’s grace, which is stronger, extends much more abundantly to many: "Who brings many sons to glory" (Heb 2:10). 433. It should be noted that he says, abounded, because God’s grace reached many not only to erase the sin incurred from Adam but also to remove actual sins and to bestow many other blessings: "God is able to provide you with every blessing in abundance" (2 Cor 9:8). For just as sin abounded from one man to many through the first suggestion of the devil, so God’s grace abounded to many through one man. Hence, he says, in the grace, i.e., through the grace, of that one man Jesus Christ. For grace is poured out by God upon many, in order that we might receive it through Christ, in whom every fullness of grace is found; "From his fullness have we all received, grace upon grace" (Jn 1:16). 434. This is how the text should be read according to Augustine’s interpretation, such that the word "many" is not taken comparatively but absolutely. So Augustine would have it that the comparison points to this, that if the sin of the one man Adam spread to many, much more will the grace of the one man Christ spread to many. But according to Ambrose the word "many" should be taken comparatively, so that the meaning is that by the sin, i.e., the actual sin, of one man, namely Adam, many, 225 not all, died by the death of sin, namely by imitating the sin of Adam by idolatry, as was explained above [n. 426]. Wisdom 13(:10) says of idolaters: "They are unhappy, and their hope is among the dead." And much more has the grace of God abounded unto many, namely more than in the idolaters who sinned in the likeness of Adam, because not only their sins are taken away by the grace of Christ but also the sins of those who persevered in the faith of the one God: "He will put away our iniquities: and he will cast all our sins into the bottom of the sea" (Mic 7:19). 435. Then when he says, and the free gift, he compares Christ’s grace to Adam’s sin as regards the effect, because not only does each affect many, but Christ’s grace had a greater effect than Adam’s sin. And concerning this he does three things. First, he states his proposition; secondly, he clarifies it [v. 16b; n. 437]; thirdly, he proves it [v. 17; n. 438]. 436. First, therefore, he says: Not only does Christ’s grace more abound for many than Adam’s sin, but it produces a greater effect in them. And this is what he says: The free gift is not like the effect of that one man’s sin. As if to say: Not as great an effect comes to many through the one sin of Adam as comes to many through the gift of Christ’s grace. For the effect of a stronger cause is stronger. Hence, since it has been established that grace is stronger than Adam’s sin, it follows that it produces a greater effect. 437. Then (v.16b) he clarifies what he has said: For the judgment, i.e., God’s punishment, following one trespass, i.e., the sin of the first parent, brought condemnation on all men, because they sinned in his sin, as stated above (v.12): "Death spread to all 226 men because all men sinned." But the free gift, which is given through Christ, following many trespasses, i.e., following not only that one original sin but also many actual sins, brings justification, i.e., comp1ete cleansing: "And such were some of you. But you were washed, you were sanctified, you were justified" (1 Cor 6:11). 438. Then when he says, If, because of one man’s trespass, he proves what he has said, namely, that Christ’s grace passes from many sins to righteousness. First, he proves this from something later; secondly, from something earlier [v. 19; n. 445]. 439. In regard to the first it should be noted that in the foregoing comparison the Apostle does not posit things that correspond, i.e., things of the same class. For on the side of sin he posits condemnation, which pertains to punishment, while on the side of grace he posits justification, which does not pertain to reward but to the state of merit. Consequently, in stating that sin brings condemnation the Apostle intends to show that grace brings justification. He uses this argument: As the condemnation of death proceeds from the first parent’s sin, so the kingdom of life proceeds from Christ’s grace. 440. For these two correspond uniformly, but no one can attain to the kingdom of life save by justice. Therefore, men are justified by Christ’s grace. First, he lays down the premises; secondly, he draws the conclusion [n. 442]. 441. He states the first premise when he says, If, because of one man’s trespass, death reigned through that one man, because it was stated above (v.12): "Sin came into the world through one man and death through sin," much more will those reign in life, namely, eternal, through the one man Jesus Christ, who says (Jn 10:10): "I came that 227 they may have life, and have it abundantly," by sharing in the eternity of life, the abundance being designated here by "kingdom." Hence, it is stated in Rev (20:4) that they will reign with Christ a thousand years, i.e., eternally. The minor premise is presented in the words, those who receive the abundance of grace and the gift of justice. As if to say: Men cannot attain to the kingdom of life except by receiving this. Here Christ’s grace is referred to the remission of sin, which no merits can anticipate and, therefore, is due entirely to grace: "If it is from works, it is no longer by grace" (Rom 11:6). Gift refers to the gifts by which men are advanced in blessings: "He gave gifts with royal liberality" (Est 2:18). Justice refers to upright actions: "Whom God made our righteousness" (1 Cor 1:30). 442. Then when he says, Therefore as one man’s trespass, he draws the intended conclusion which states the same thing as stated earlier, namely, that as by the sin of one man, Adam, the divine judgment led all men born of him according to the flesh to death, so by the righteous of one, namely, Christ, divine grace passed to all men, leading to acquittal and life for all men. 443. But this seems false, since not all men are justified by Christ, although all men die through Adam. To answer this it must be noted that just as all men born according to the flesh from Adam incur condemnation through his sin, so all men who are reborn spiritually through Christ obtain the justification of life, because, as stated in Jn (3:5): "Unless one is born of water and the spirit, he cannot enter the kingdom of God." 228 Although it can be said that Christ’s justification passes on to justify all men in the sense that it is capable of doing so, although de facto it passes only to believers. Hence, it is stated in 1 Tim (4:10): "He is the Savior of all men, especially of those who believe." 444. From what is said here we should gather that as no one dies except through Adam’s sin, so no one is justified except through Christ’s righteousness; and this is brought about through faith in him "The righteousness of God through faith in Jesus Christ for all who believe" (Rom 3:22). But the men who believe in him are not only those who lived after the resurrection but even those who lived before. For as we believe in him as one who was born and suffered, so they believed in him as one who would be born and suffer. Hence, our faith and theirs is the same: "Having the same spirit of faith…we too believe and so we speak" (2 Cor 4:13). Thus it is that the grace of Christ redounds to the justification of many by appeal to something later, namely to the reign of life. 445. Then the Apostle proves the same thing from something prior, when he says, For as by one man’s disobedience. For causes are similar to their effects. But the disobedience of the first parent, which bears the character of unrighteousness, made men sinners and unrighteous. Therefore, the obedience of Christ, which bears the character of righteousness, made them righteous. And this is what he stated previously, namely, that grace proceeds forth into all men unto justification (v.16). 229 446. But there seems to be some problem about the statement that by one man’s disobedience many were made sinners, i.e., all who are born from his seed. For his first sin seems to have been pride rather than disobedience, as is stated in Sir (10:13): "The beginning of every sin is pride." In answer it must be noted that the same writer says in 10(:21), "The beginning of pride makes men separate themselves from God," because the first step of pride consists in a man’s not willing to be subject to God’s precepts, which pertains to disobedience. Hence, man’s first sin seems to have been disobedience, not as far as the outward action was concerned but in regard to the inner movement of pride, by which be wills to go against the divine command. Hence, the Lord reproves his disobedience: "Because you have listened to the voice of your wife and have eaten of the tree of which I commanded you, ‘You shall not eat of it, cursed is the ground…in your work. In you labor you shall eat from it all the days of your life" (Gen 3:17). On the other hand Christ’s obedience consisted in accepting death for our salvation in accordance with the Father’s command: "He became obedient unto death" (Phil 2:8). This, of course, does not contradict the statement that Christ died out of love for us (Eph 5:2), because the obedience proceeded from the love he had for the Father and for us. 447. And one should not that by obedience and disobedience he proves that through one man we were made sinners and through one man we were justified, because legal justice, which is the ensemble of all virtues, is recognizable in observing the precepts of the law, which pertains to the notion of obedience. But legal injustice, which 230 is the ensemble of all wickedness, is recognizable in transgressing the precepts of the law, which pertains to the notion of disobedience. Consequently, it is fittingly stated that by obedience men were made just and by disobedience sinners.
