SECOND ARTICLE [I-II, Q. 81, Art. 2]

Whether Also Other Sins of the First Parent or of Nearer Ancestors

Are Transmitted to Their Descendants?

Objection 1: It would seem that also other sins, whether of the first

parent or of nearer ancestors, are transmitted to their descendants.

For punishment is never due unless for fault. Now some are punished

by the judgment of God for the sin of their immediate parents,

according to Ex. 20:5: "I am . . . God . . . jealous, visiting the

iniquity of the fathers upon the children, unto the third and fourth

generation." Furthermore, according to human law, the children of

those who are guilty of high treason are disinherited. Therefore the

guilt of nearer ancestors is also transmitted to their descendants.

Obj. 2: Further, a man can better transmit to another, that which he

has of himself, than that which he has received from another: thus

fire heats better than hot water does. Now a man transmits to his

children, by the way, of origin, the sin which he has from Adam. Much

more therefore should he transmit the sin which he has contracted of

himself.

Obj. 3: Further, the reason why we contract original sin from our

first parent is because we were in him as in the principle of our

nature, which he corrupted. But we were likewise in our nearer

ancestors, as in principles of our nature, which however it be

corrupt, can be corrupted yet more by sin, according to Apoc. 22:11:

"He that is filthy, let him be filthier still." Therefore children

contract, by the way of origin, the sins of their nearer ancestors,

even as they contract the sin of their first parent.

_On the contrary,_ 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.

_I answer that,_ 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 First Part (Q. 100, A. 1), 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.

Reply Obj. 1: According to Augustine in his letter to Avitus [*Ep. ad

Auxilium ccl.], children are never inflicted with spiritual punishment

on account of their parents, unless they share in their guilt, either

in their origin, or by imitation, because every soul is God's

immediate property, as stated in Ezech. 18:4. Sometimes, however, by

Divine or human judgment, children receive bodily punishment on their

parents' account, inasmuch as the child, as to its body, is part of

its father.

Reply Obj. 2: A man can more easily transmit that which he has of

himself, provided it be transmissible. But the actual sins of our

nearer ancestors are not transmissible, because they are purely

personal, as stated above.

Reply Obj. 3: The first sin infects nature with a human corruption

pertaining to nature; whereas other sins infect it with a corruption

pertaining only to the person.
