TENTH ARTICLE [I-II, Q. 74, Art. 10]

Whether Venial Sin Can Be in the Higher Reason As Such?

Objection 1: It would seem that venial sin cannot be in the higher

reason as such, i.e. as considering the eternal law. For the act of a

power is not found to fail except that power be inordinately disposed

with regard to its object. Now the object of the higher reason is the

eternal law, in respect of which there can be no disorder without

mortal sin. Therefore there can be no venial sin in the higher reason

as such.

Obj. 2: Further, since the reason is a deliberative power, there can

be no act of reason without deliberation. Now every inordinate

movement in things concerning God, if it be deliberate, is a mortal

sin. Therefore venial sin is never in the higher reason as such.

Obj. 3: Further, it happens sometimes that a sin which takes us

unawares, is a venial sin. Now a deliberate sin is a mortal sin,

through the reason, in deliberating, having recourse to some higher

good, by acting against which, man sins more grievously; just as when

the reason in deliberating about an inordinate pleasurable act,

considers that it is contrary to the law of God, it sins more

grievously in consenting, than if it only considered that it is

contrary to moral virtue. But the higher reason cannot have recourse

to any higher tribunal than its own object. Therefore if a movement

that takes us unawares is not a mortal sin, neither will the

subsequent deliberation make it a mortal sin; which is clearly false.

Therefore there can be no venial sin in the higher reason as such.

_On the contrary,_ A sudden movement of unbelief is a venial sin. But

it belongs to the higher reason as such. Therefore there can be a

venial sin in the higher reason as such.

_I answer that,_ The higher reason regards its own object otherwise

than the objects of the lower powers that are directed by the higher

reason. For it does not regard the objects of the lower powers,

except in so far as it consults the eternal law about them, and so it

does not regard them save by way of deliberation. Now deliberate

consent to what is a mortal sin in its genus, is itself a mortal sin;

and consequently the higher reason always sins mortally, if the acts

of the lower powers to which it consents are mortal sins.

With regard to its own object it has a twofold act, viz. simple

_intuition,_ and _deliberation,_ in respect of which it again

consults the eternal law about its own object. But in respect of

simple intuition, it can have an inordinate movement about Divine

things, as when a man suffers a sudden movement of unbelief. And

although unbelief, in its genus, is a mortal sin, yet a sudden

movement of unbelief is a venial sin, because there is no mortal sin

unless it be contrary to the law of God. Now it is possible for one

of the articles of faith to present itself to the reason suddenly

under some other aspect, before the eternal law, i.e. the law of God,

is consulted, or can be consulted, on the matter; as, for instance,

when a man suddenly apprehends the resurrection of the dead as

impossible naturally, and rejects it, as soon as he had thus

apprehended it, before he has had time to deliberate and consider

that this is proposed to our belief in accordance with the Divine

law. If, however, the movement of unbelief remains after this

deliberation, it is a mortal sin. Therefore, in sudden movements, the

higher reason may sin venially in respect of its proper object, even

if it be a mortal sin in its genus; or it may sin mortally in giving

a deliberate consent; but in things pertaining to the lower powers,

it always sins mortally, in things which are mortal sins in their

genus, but not in those which are venial sins in their genus.

Reply Obj. 1: A sin which is against the eternal law, though it be

mortal in its genus, may nevertheless be venial, on account of the

incompleteness of a sudden action, as stated.

Reply Obj. 2: In matters of action, the simple intuition of the

principles from which deliberation proceeds, belongs to the reason,

as well as the act of deliberation: even as in speculative matters it

belongs to the reason both to syllogize and to form propositions:

consequently the reason also can have a sudden movement.

Reply Obj. 3: One and the same thing may be the subject of different

considerations, of which one is higher than the other; thus the

existence of God may be considered, either as possible to be known by

the human reason, or as delivered to us by Divine revelation, which

is a higher consideration. And therefore, although the object of the

higher reason is, in its nature, something sublime, yet it is

reducible to some yet higher consideration: and in this way, that

which in the sudden movement was not a mortal sin, becomes a mortal

sin in virtue of the deliberation which brought it into the light of

a higher consideration, as was explained above.
