Of the Cause of Sin, on the Part of Man

Of the Cause of Sin, on the Part of Man — St. Thomas Aquinas asks: Whether the first sin of our first parent is contracted by his descendants, by way of origin?; Whether also other sins of the first parent or of nearer ancestors are transmitted to their descendants?; Whether the sin of the first parent is transmitted, by the way of origin, to all men?; Whether original sin would be contracted by a person formed miraculously from human flesh?; Whether if Eve, and not Adam, had sinned, their children would have contracted original sin?.

We must now consider the cause of sin, on the part of man. Now, while man, like the devil, is the cause of another's sin, by outward suggestion, he has a certain special manner of causing sin, by way of origin. Wherefore we must speak about original sin, the consideration of which will be three-fold: (1) Of its transmission; (2) of its essence; (3) of its subject.

Under the first head there are five points of inquiry:

Article 1: Whether the first sin of our first parent is contracted by his descendants, by way of origin?

The Apostle says (Rom. 5:12): "By one man sin entered into this world, and by sin death." Nor can this be understood as denoting imitation or suggestion, since it is written (Wis. 2:24): "By the envy of the devil, death came into this world." It follows therefore that through origin from the first man sin entered into the world.

According to the Catholic Faith we are bound to hold that the first sin of the first man is transmitted to his descendants, by way of origin. For this reason children are taken to be baptized soon after their birth, to show that they have to be washed from some uncleanness. The contrary is part of the Pelagian heresy, as is clear from Augustine in many of his books [*For instance, Retract. i, 9; De Pecc. Merit. et Remiss. ix; Contra Julian. iii, 1; De Dono Persev. xi, xii.]

In endeavoring to explain how the sin of our first parent could be transmitted by way of origin to his descendants, various writers have gone about it in various ways. For some, considering that the subject of sin is the rational soul, maintained that the rational soul is transmitted with the semen, so that thus an infected soul would seem to produce other infected souls. Others, rejecting this as erroneous, endeavored to show how the guilt of the parent's soul can be transmitted to the children, even though the soul be not transmitted, from the fact that defects of the body are transmitted from parent to child---thus a leper may beget a leper, or a gouty man may be the father of a gouty son, on account of some seminal corruption, although this corruption is not leprosy or gout. Now since the body is proportionate to the soul, and since the soul's defects redound into the body, and vice versa, in like manner, say they, a culpable defect of the soul is passed on to the child, through the transmission of the semen, albeit the semen itself is not the subject of the guilt.

But all these explanations are insufficient. Because, granted that some bodily defects are transmitted by way of origin from parent to child, and granted that even some defects of the soul are transmitted in consequence, on account of a defect in the bodily habit, as in the case of idiots begetting idiots; nevertheless the fact of having a defect by the way of origin seems to exclude the notion of guilt, which is essentially something voluntary. Wherefore granted that the rational soul were transmitted, from the very fact that the stain on the child's soul is not in its will, it would cease to be a guilty stain binding its subject to punishment; for, as the Philosopher says (Ethic. iii, 5), "no one reproaches a man born blind; one rather takes pity on him."

Therefore we must explain the matter otherwise by saying that all men born of Adam may be considered as one man, inasmuch as they have one common nature, which they receive from their first parents; even as in civil matters, all who are members of one community are reputed as one body, and the whole community as one man. Indeed Porphyry says (Praedic., De Specie) that "by sharing the same species, many men are one man." Accordingly the multitude of men born of Adam, are as so many members of one body. Now the action of one member of the body, of the hand for instance, is voluntary not by the will of that hand, but by the will of the soul, the first mover of the members. Wherefore a murder which the hand commits would not be imputed as a sin to the hand, considered by itself as apart from the body, but is imputed to it as something belonging to man and moved by man's first moving principle. In this way, then, the disorder which is in this man born of Adam, is voluntary, not by his will, but by the will of his first parent, who, by the movement of generation, moves all who originate from him, even as the soul's will moves all the members to their actions. Hence the sin which is thus transmitted by the first parent to his descendants is called "original," just as the sin which flows from the soul into the bodily members is called "actual." And just as the actual sin that is committed by a member of the body, is not the sin of that member, except inasmuch as that member is a part of the man, for which reason it is called a "human sin"; so original sin is not the sin of this person, except inasmuch as this person receives his nature from his first parent, for which reason it is called the "sin of nature," according to Eph. 2:3: "We . . . were by nature children of wrath."

Article 2: Whether also other sins of the first parent or of nearer ancestors are transmitted to their descendants?

Good is more self-diffusive than evil. But the merits of the nearer ancestors are not transmitted to their descendants. Much less therefore are their sins.

Augustine puts this question in the Enchiridion xlvi, xlvii, and leaves it unsolved. Yet if we look into the matter carefully we shall see that it is impossible for the sins of the nearer ancestors, or even any other but the first sin of our first parent to be transmitted by way of origin. The reason is that a man begets his like in species but not in individual. Consequently those things that pertain directly to the individual, such as personal actions and matters affecting them, are not transmitted by parents to their children: for a grammarian does not transmit to his son the knowledge of grammar that he has acquired by his own studies. On the other hand, those things that concern the nature of the species, are transmitted by parents to their children, unless there be a defect of nature: thus a man with eyes begets a son having eyes, unless nature fails. And if nature be strong, even certain accidents of the individual pertaining to natural disposition, are transmitted to the children, e.g. fleetness of body, acuteness of intellect, and so forth; but nowise those that are purely personal, as stated above.

Now just as something may belong to the person as such, and also something through the gift of grace, so may something belong to the nature as such, viz. whatever is caused by the principles of nature, and something too through the gift of grace. In this way original justice, as stated in the , was a gift of grace, conferred by God on all human nature in our first parent. This gift the first man lost by his first sin. Wherefore as that original justice together with the nature was to have been transmitted to his posterity, so also was its disorder. Other actual sins, however, whether of the first parent or of others, do not corrupt the nature as nature, but only as the nature of that person, i.e. in respect of the proneness to sin: and consequently other sins are not transmitted.

Article 3: Whether the sin of the first parent is transmitted, by the way of origin, to all men?

The Apostle says (Rom. 5:12): "Death passed upon all men in whom all have sinned."

According to the Catholic Faith we must firmly believe that, Christ alone excepted, all men descended from Adam contract original sin from him; else all would not need redemption [*Cf. Translator's note inserted before ] which is through Christ; and this is erroneous. The reason for this may be gathered from what has been stated (), viz. that original sin, in virtue of the sin of our first parent, is transmitted to his posterity, just as, from the soul's will, actual sin is transmitted to the members of the body, through their being moved by the will. Now it is evident that actual sin can be transmitted to all such members as have an inborn aptitude to be moved by the will. Therefore original sin is transmitted to all those who are moved by Adam by the movement of generation.

Article 4: Whether original sin would be contracted by a person formed miraculously from human flesh?

They would not have been in Adam "according to seminal virtue," which alone is the cause of the transmission of original sin, as Augustine states (Gen. ad lit. x, 18, seqq.).

As stated above (), original sin is transmitted from the first parent to his posterity, inasmuch as they are moved by him through generation, even as the members are moved by the soul to actual sin. Now there is no movement to generation except by the active power of generation: so that those alone contract original sin, who are descended from Adam through the active power of generation originally derived from Adam, i.e. who are descended from him through seminal power; for the seminal power is nothing else than the active power of generation. But if anyone were to be formed by God out of human flesh, it is evident that the active power would not be derived from Adam. Consequently he would not contract original sin: even as a hand would have no part in a human sin, if it were moved, not by the man's will, but by some external power.

Article 5: Whether if Eve, and not Adam, had sinned, their children would have contracted original sin?

The Apostle says (Rom. 5:12): "By one man sin entered into this world." Now if the woman would have transmitted original sin to her children, he should have said that it entered by two, since both of them sinned, or rather that it entered by a woman, since she sinned first. Therefore original sin is transmitted to the children, not by the mother, but by the father.

The solution of this question is made clear by what has been said. For it has been stated () that original sin is transmitted by the first parent in so far as he is the mover in the begetting of his children: wherefore it has been said () that if anyone were begotten materially only, of human flesh, they would not contract original sin. Now it is evident that in the opinion of philosophers, the active principle of generation is from the father, while the mother provides the matter. Therefore original sin, is contracted, not from the mother, but from the father: so that, accordingly, if Eve, and not Adam, had sinned, their children would not contract original sin: whereas, if Adam, and not Eve, had sinned, they would contract it.
