I speak after the manner of men because of the weakness of your flesh: for as you have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness.

AD 1274
After showing with a reason based on God’s grace that we should not continue in sin but should serve God, the Apostle shows the same thing with a reason based on a condition of the former life. In regard to this he does three things: first, he describes the terms in which he will present his teaching; secondly, he presents the teaching [v. 19b; n. 506]; thirdly, be gives the reason for the teaching [v. 20; n. 507]. 505. First, therefore, he says: I have advised that you yield yourselves to God. I am now speaking to you in human terms, i.e., as suited to human feebleness. For man is sometimes so presented in Scripture to signify a weakness of the human condition: "I am a weak man, and of a short time, and falling short of the understanding of judgment and laws" (Wis 9:5); "Since there are jealousy and strife among you, are you not carnal and walking as mere men?" (1 Cor 3:3). He assigns the cause, when he adds, because of the limitations; for it is to the mature that the more perfect precepts are given: "Wisdom, however, we speak among those who are mature" (1 Cor 2:6); "Solid food is for the mature" (Heb 5:14), but lighter precepts are given to weaker men: "As to little ones in Christ, I fed you with milk, not 256 with solid food" (1 Cor 3:1); "You have become such as have need of milk and not of solid food" (Heb 5:12). But this weakness comes not from the spirit but from the flesh, because the body, which is subject to decay is a load on the soul, as it says in Wis (9:15); hence, he adds: of your flesh: "The spirit is willing, but the flesh is weak" (Mt 26:41). 506. Then (v.19b) he presents the teaching he called human, in which he teaches that the body must be yielded to the slavery of righteousness in the same measure as we yielded it to the slavery of sin. And this is what he says: For just as you once yielded your members, namely, by doing evil works, to impurity and to iniquity born in the heart. Here "impurity" refers to sins of the flesh: "But immorality and every uncleanness, let it not even be named among you" (Eph 5:3), and "iniquity" to spiritual sins, particularly those that harm one’s neighbor: "He plots mischief [iniquity] while on his bed" (Ps 36:4). So now, set free from sin, yield your members, namely, by performing good works, to righteousness proposed to us in the divine law: and this for sanctification, i.e., for the increase of holiness: "Let the holy still be holy" (Rev 22:11). He calls this human, because right reason demands that man serve righteousness more than he previously served sin: "For as it was your mind to go astray from God; so when you return again, you shal1 seek him ten times as much (Bar 4:28). 507. Then when he says, When you were slaves, he assigns the reason for this teaching. In regard to this he does two things: first, he presents a reason for the teaching; secondly, he proves something he had presupposed [v. 23; n. 516]. 257 The reason behind the above teaching is that the state of grace is preferable to the state of sin. For if more benefits accrue to us from the state of righteousness than from sin, we should be more eager to serve righteousness than we were to serve sin. First, therefore, he describes the state of sin; secondly, the state of righteousness [v. 22; n. 512]. In regard to the first he does three things: first, he describes the condition of the sinner; secondly, the effect of sin [v. 21; n. 510]; thirdly, its end [v. 21b; n. 511]. 508. In regard to the first it should be noted that man is by nature free because of his reason and will, which cannot be forced but can be inclined by certain things. Therefore, in regard to the freedom of the will man is always free of compulsion, although he is not free of inclinations. For the free judgment is sometimes inclined to the good through the habit of grace or righteousness; and then it is in slavery to righteousness but free from sin. But sometimes the free judgment is inclined to evil through the habit of sin; and then it is in slavery to sin and free from righteousness. Now, slavery to sin consists in being drawn to consent to sin against the judgment of reason: "Everyone who commits sin is the slave of sin" (Jn 8:34). And in regard to this he says: When you were slaves of sin. Freedom from righteousness, on the other hand, implies that a man rushes headlong into sin without the restraint of righteousness; in regard to this he says: you were free in regard to righteousness. This happens especially in those who sin of set purpose: "Long ago you 258 broke your yoke and burst your bonds; and you said, ‘I will not serve’" (Jer 2:20); "A vain man is lifted up into pride, and thinks himself born free like a wild ass’ colt" (Jb 11:12). 509. Yet it should be noted that this state involves true slavery and only apparent freedom. For since man should act according to reason, be is truly a slave when he is led away from what is reasonable by something alien. Furthermore, if he is not restrained by the yoke of reason from following concupiscence, he is free only in the opinion of those who suppose that the highest good is to follow one’s concupiscence. 510. Then (v.21) he shows the effect of sin. One effect he excludes, namely, a fruitful return, when he says: But then what return did you get, namely, when you were committing those sins. For the works of sin are unfruitful, because they do not help man to obtain happiness: Their works are unprofitable works" (Is 59:6); "Woe to you that devise that which is unprofitable and work evil in your beds" (Mic 2:1). The effect he mentions is confusion, saying: from the things, namely, the sins, of which you are now, in the state of repentance, ashamed because of their baseness. "You shall be ashamed of the gardens" (Is 1:29), namely, of the pleasure you had chosen. 511. Then (v.21b) he mentions the end of sin, saying: For the end of those things, namely of sins, is death. This of course is not the objective in the mind of the sinner, because be does not intend to incur death by sin; nevertheless, it is the end of those sins, because of their very nature they bring temporal death. For when the soul separates God from itself, it 259 deserves to have its body separated from it. Sins also bring eternal death, because when one wills to be separated from God for a time, he deserves to be separated from him forever; and this is eternal death: "Those who do such things deserve to die" (Rom 1:32). 512. Then (v.22) he describes the state of righteousness: first, he describes a condition of this state; secondly, the effect [v. 22b; n. 514]; thirdly, the end [v. 22c; n. 515]. 513. In regard to the first it should be noted that just as when one is by sin inclined to evil, he is free from righteousness, so when one is by the habit of righteousness and grace inclined to good, he is free from sin, so that he is not overcome by it to the point of consenting to it. Hence he says: But now in the state of righteousness, having been set free from sin: "If the Son makes you free, you will be free indeed" (Jn 8:36). On the other hand, just as in the state of sin one is a slave of sin which he obeys, so in the state of righteousness one is a slave of God and obeys him willingly: "Serve the Lord with gladness" (Ps 100:2); "O Lord, I am thy servant" Ps 116 (v.16). And this is what he adds: you have become slaves of God. But this is true freedom and the best form of slavery, because by righteousness man is inclined to what befits him and is turned from what befits concupiscence which is distinctively bestial. 514. Then (v.22b) he mentions the effect of righteousness, saying: The return you get is sanctification, i.e., the fruit of sanctity by good works is your return, inasmuch as 260 these please you in a spiritual and holy way: "My flowers are the fruit of honor and riches" (Si 24:23). 515. After that he mentions the end, saying, and its end, eternal life, which is the goal of all just men who do all their works for the sake of obtaining eternal life: "Seek first the kingdom of God and all these things will be added unto you" (Mt 6:33). It is also the end of the works themselves which merit eternal life, since they are done out of obedience to God and in imitation of God: "My sheep hear my voice, and they follow me; and I give them eternal life" (Jn 10:27). 516. Then (v.22c) he clarifies what he had said about the ends of evil and of good. First, in regard to evil he says: We have stated that the end of sins is death: the wages of sin is death. Wages or stipends were the salaries paid soldiers. These were paid in money. Therefore, because by sinning one makes war by using his members as arms for sin, death is said to be the wages of sin, i.e., the return paid to those who serve it. Death, therefore, is the return which pays those who are its slaves. It is not the end they seek but the end paid to them: "On the wicked he will rain coals of fire and brimstone; a scorching wind will be the portion of their cup" (Ps 11:6). 517. In regard to the good he says: The free gift [grace] of God is eternal life. For since he had said that just men have eternal life, which it is certain cannot be had except through grace, then the very fact that we do what is good and that our works are worthy of eternal life is the result of God’s grace: "He bestows grace and glory" (Ps 84:11). Thus, therefore, if our works are considered in themselves and as coming from our free will they do not merit eternal life ex condigno, but only as coming from the grace 261 of the Holy Spirit. Hence it says in Jn (4:14): "The water that I shall give him will become in him a spring of water welling up to eternal life." And this in Christ Jesus our Lord, i.e., through Christ or inasmuch as we exist in him through faith and love: "Every one who sees the Son and believes in him has eternal life" (Jn 6:40). 2
