Chapter 5.--What is the Special Advantage in the Pelagian Opinions?
What advantage, then, is it to them that they say "that all sin descends not from nature, but from the will," and resist by the truth of this judgment the Manicheans, who say that evil nature is the cause of sin; when by being unwilling to admit original sin although itself also descends from the will of the first man, they make infants to depart in guilt from the body? What advantage is it to them "that they confess that baptism is necessary for all ages," while the Manicheans say that it is superfluous for every age, while they say that in infants it is false so far as it pertains to the forgiveness of sins? What advantage is it to them that they maintain "the flesh of Christ" (which the Manicheans contend was either no flesh at all, or a feigned flesh) to have been not only the true flesh, but also "that the soul itself was stained by no spot of sin," when other infants are by them so put on the same level with His infancy, with not unequal purity, as that both that flesh does not appear to keep its own holiness in comparison with these, and these obtain no salvation from that?
Chapter 6.--Not Death Alone, But Sin Also Has Passed into Us by Means of Adam.
In that particular, indeed, wherein they say "that death passed to us by Adam, not sins," they have not the Manicheans as their adversaries: since they, too, deny that original sin from the first man, at first of pure and upright body and spirit, and afterwards depraved by free will, subsequently passed and passes as sin into all with death; but they say that the flesh was evil from the beginning, and was created by an evil spirit and along with an evil spirit; but that a good soul--a portion, to wit, of God--for the deserts of its defilement by food and drink, in which it was before bound up, came into man, and thus by means of copulation was bound in the chain of the flesh. And thus the Manicheans agree with the Pelagians that it was not the guilt of the first man that passed into the human race--neither by the flesh, which they say was never good; nor by the soul, which they assert comes into the flesh of man with the merits of its own defilements with which it was polluted before the flesh. But how do the Pelagians say "that only death passed upon us by Adam's means"? For if we die because he died, but he died because be sinned, they say that the punishment passed without the guilt, and that innocent infants are punished with an unjust penalty by deriving death without the deserts of death. This, the catholic faith has known of the one and only mediator between God and man, the man Christ Jesus, who condescended to undergo death--that is, the penalty of sin--without sin, for us. As He alone became the Son of man, in order that we might become through Him sons of God, so He alone, on our behalf, undertook punishment without ill deservings, that we through Him might obtain grace without good deservings. Because as to us nothing good was due so to Him nothing bad was due. Therefore, commending His love to them to whom He was about to give undeserved life, He was willing to suffer for them an undeserved death. This special prerogative of the Mediator the Pelagians endeavour to make void, so that this should no longer be special in the Lord, if Adam in such wise suffered a death due to him on account of his guilt, as that infants, drawing from him no guilt, should suffer undeserved death. For although very much good is conferred on the good by means of death, whence some have fitly argued even "of the benefit of death;" yet from this what can be declared except the mercy of God, since the punishment of sin is converted into beneficent uses?
Chapter 7.--What is the Meaning of "In Whom All Have Sinned"?
But these speak thus who wish to wrest men from the apostle's words into their own thought. For where the apostle says, "By one man sin entered into the world, and death by sin, and so passed upon all men," [2784] they will have it there understood not that "sin" passed over, but "death." What, then, is the meaning of what follows, "Whereto all have sinned"? For either the apostle says that in that "one man" all have sinned of whom he had said, "By one man sin entered into the world," or else in that "sin," or certainly in "death." For it need not disturb us that he said not "in which" [using the feminine form of the pronoun], but "in whom" [using the masculine] all have sinned; since "death" in the Greek language is of the masculine gender. Let them, then, choose which they will,--for either in that "man" all have sinned, and it is so said because when he sinned all were in him; or in that "sin" all have sinned, because that was the doing of all in general which all those who were born would have to derive; or it remains for them to say that in that "death" all sinned. But in what way this can be understood, I do not clearly see. For all die in the sin; they do not sin in the death; for when sin precedes, death follows--not when death precedes, sin follows. Because sin is the sting of death--that is, the sting by whose stroke death occurs, not the sting with which death strikes. [2785] Just as poison, if it is drunk, is called the cup of death, because by that cup death is caused, not because the cup is caused by the death, or is given by death. But if "sin" cannot be understood by those words of the apostle as being that "wherein all have sinned," because in Greek, from which the Epistle is translated, "sin" is expressed in the feminine gender, it remains that all men are understood to have sinned in that first "man," because all men were in him when he sinned; and from him sin is derived by birth, and is not remitted save by being born again. For thus also the sainted Hilary understood what is written, "wherein all have sinned;" for he says, "wherein," that is, in Adam, "all have sinned." [2786] Then he adds, "It is manifest that all have sinned in Adam, as it were in the mass; for he himself was corrupted by sin, and all whom he begot were born under sin." When he wrote this, Hilary, without any ambiguity, indicated how we should understand the words, "wherein all have sinned."
