Summa Theologica Part II (Pars Prima Secundae) Part 118

Reply Obj. 1: Consent is an act of the appet.i.tive power, not absolutely, but in consequence of an act of reason deliberating and judging, as stated above (Q. 15, A. 3). Because the fact that the consent is finally given to a thing is due to the fact that the will tends to that upon which the reason has already pa.s.sed its judgment.

Hence consent may be ascribed both to the will and to the reason.

Reply Obj. 2: The higher reason is said to consent, from the very fact that it fails to direct the human act according to the Divine law, whether or not it advert to the eternal law. For if it thinks of G.o.d's law, it holds it in actual contempt: and if not, it neglects it by a kind of omission. Therefore the consent to a sinful act always proceeds from the higher reason: because, as Augustine says (De Trin.

xii, 12), "the mind cannot effectively decide on the commission of a sin, unless by its consent, whereby it wields its sovereign power of moving the members to action, or of restraining them from action, it become the servant or slave of the evil deed."

Reply Obj. 3: The higher reason, by considering the eternal law, can direct or restrain the internal delectation, even as it can direct or restrain the external action: nevertheless, before the judgment of the higher reason is p.r.o.nounced the lower reason, while deliberating the matter in reference to temporal principles, sometimes approves of this delectation: and then the consent to the delectation belongs to the lower reason. If, however, after considering the eternal law, man persists in giving the same consent, such consent will then belong to the higher reason.

Reply Obj. 4: The apprehension of the power of imagination is sudden and indeliberate: wherefore it can cause an act before the higher or lower reason has time to deliberate. But the judgment of the lower reason is deliberate, and so requires time, during which the higher reason can also deliberate; consequently, if by its deliberation it does not check the sinful act, this will deservedly be imputed to it.

EIGHTH ARTICLE [I-II, Q. 74, Art. 8]

Whether Consent to Delectation Is a Mortal Sin?

Objection 1: It would seem that consent to delectation is not a mortal sin, for consent to delectation belongs to the lower reason, which does not consider the eternal types, i.e. the eternal law, and consequently does not turn away from them. Now every mortal sin consists in turning away from the Divine law, as is evident from Augustine's definition of mortal sin, which was quoted above (Q. 71, A. 6). Therefore consent to delectation is not a mortal sin.

Obj. 2: Further, consent to a thing is not evil, unless the thing to which consent is given be evil. Now "the cause of anything being such is yet more so," or at any rate not less. Consequently the thing to which a man consents cannot be a lesser evil than his consent. But delectation without deed is not a mortal sin, but only a venial sin.

Therefore neither is the consent to the delectation a mortal sin.

Obj. 3: Further, delectations differ in goodness and malice, according to the difference of the deeds, as the Philosopher states (Ethic. x, 3, 5). Now the inward thought is one thing, and the outward deed, e.g. fornication, is another. Therefore the delectation consequent to the act of inward thought, differs in goodness and malice from the pleasure of fornication, as much as the inward thought differs from the outward deed; and consequently there is a like difference of consent on either hand. But the inward thought is not a mortal sin, nor is the consent to that thought: and therefore neither is the consent to the delectation.

Obj. 4: Further, the external act of fornication or adultery is a mortal sin, not by reason of the delectation, since this is found also in the marriage act, but by reason of an inordinateness in the act itself. Now he that consents to the delectation does not, for this reason, consent to the inordinateness of the act. Therefore he seems not to sin mortally.

Obj. 5: Further, the sin of murder is more grievous than simple fornication. Now it is not a mortal sin to consent to the delectation resulting from the thought of murder. Much less therefore is it a mortal sin to consent to the delectation resulting from the thought of fornication.

Obj. 6: Further, the Lord's prayer is recited every day for the remission of venial sins, as Augustine a.s.serts (Enchiridion lxxviii).

Now Augustine teaches that consent to delectation may be driven away by means of the Lord's Prayer: for he says (De Trin. xii, 12) that "this sin is much less grievous than if it be decided to fulfil it by deed: wherefore we ought to ask pardon for such thoughts also, and we should strike our b.r.e.a.s.t.s and say: 'Forgive us our trespa.s.ses.'"

Therefore consent to delectation is a venial sin.

_On the contrary,_ Augustine adds after a few words: "Man will be altogether lost unless, through the grace of the Mediator, he be forgiven those things which are deemed mere sins of thought, since without the will to do them, he desires nevertheless to enjoy them."

But no man is lost except through mortal sin. Therefore consent to delectation is a mortal sin.

_I answer that,_ There have been various opinions on this point, for some have held that consent to delectation is not a mortal sin, but only a venial sin, while others have held it to be a mortal sin, and this opinion is more common and more probable. For we must take note that since every delectation results from some action, as stated in _Ethic._ x, 4, and again, that since every delectation may be compared to two things, viz. to the operation from which it results, and to the object in which a person takes delight. Now it happens that an action, just as a thing, is an object of delectation, because the action itself can be considered as a good and an end, in which the person who delights in it, rests. Sometimes the action itself, which results in delectation, is the object of delectation, in so far as the appet.i.tive power, to which it belongs to take delight in anything, is brought to bear on the action itself as a good: for instance, when a man thinks and delights in his thought, in so far as his thought pleases him; while at other times the delight consequent to an action, e.g. a thought, has for its object another action, as being the object of his thought; and then his thought proceeds from the inclination of the appet.i.te, not indeed to the thought, but to the action thought of. Accordingly a man who is thinking of fornication, may delight in either of two things: first, in the thought itself, secondly, in the fornication thought of. Now the delectation in the thought itself results from the inclination of the appet.i.te to the thought; and the thought itself is not in itself a mortal sin; sometimes indeed it is only a venial sin, as when a man thinks of such a thing for no purpose; and sometimes it is no sin at all, as when a man has a purpose in thinking of it; for instance, he may wish to preach or dispute about it. Consequently such affection or delectation in respect of the thought of fornication is not a mortal sin in virtue of its genus, but is sometimes a venial sin and sometimes no sin at all: wherefore neither is it a mortal sin to consent to such a thought. In this sense the first opinion is true.

But that a man in thinking of fornication takes pleasure in the act thought of, is due to his desire being inclined to this act.

Wherefore the fact that a man consents to such a delectation, amounts to nothing less than a consent to the inclination of his appet.i.te to fornication: for no man takes pleasure except in that which is in conformity with his appet.i.te. Now it is a mortal sin, if a man deliberately chooses that his appet.i.te be conformed to what is in itself a mortal sin. Wherefore such a consent to delectation in a mortal sin, is itself a mortal sin, as the second opinion maintains.

Reply Obj. 1: Consent to delectation may be not only in the lower reason, but also in the higher reason, as stated above (A. 7).

Nevertheless the lower reason may turn away from the eternal types, for, though it is not intent on them, as regulating according to them, which is proper to the higher reason, yet, it is intent on them, as being regulated according to them: and by turning from them in this sense, it may sin mortally; since even the acts of the lower powers and of the external members may be mortal sins, in so far as the direction of the higher reason fails in directing them according to the eternal types.

Reply Obj. 2: Consent to a sin that is venial in its genus, is itself a venial sin, and accordingly one may conclude that the consent to take pleasure in a useless thought about fornication, is a venial sin. But delectation in the act itself of fornication is, in its genus, a mortal sin: and that it be a venial sin before the consent is given, is accidental, viz. on account of the incompleteness of the act: which incompleteness ceases when the deliberate consent has been given, so that therefore it has its complete nature and is a mortal sin.

Reply Obj. 3: This argument considers the delectation which has the thought for its object.

Reply Obj. 4: The delectation which has an external act for its object, cannot be without complacency in the external act as such, even though there be no decision to fulfil it, on account of the prohibition of some higher authority: wherefore the act is inordinate, and consequently the delectation will be inordinate also.

Reply Obj. 5: The consent to delectation, resulting from complacency in an act of murder thought of, is a mortal sin also: but not the consent to delectation resulting from complacency in the thought of murder.

Reply Obj. 6: The Lord's Prayer is to be said in order that we may be preserved not only from venial sin, but also from mortal sin.

NINTH ARTICLE [I-II, Q. 74, Art. 9]

Whether There Can Be Venial Sin in the Higher Reason As Directing the Lower Powers?

Objection 1: It would seem that there cannot be venial sin in the higher reason as directing the lower powers, i.e. as consenting to a sinful act. For Augustine says (De Trin. xii, 7) that the "higher reason is intent on considering and consulting the eternal law." But mortal sin consists in turning away from the eternal law. Therefore it seems that there can be no other than mortal sin in the higher reason.

Obj. 2: Further, the higher reason is the principle of the spiritual life, as the heart is of the body's life. But the diseases of the heart are deadly. Therefore the sins of the higher reason are mortal.

Obj. 3: Further, a venial sin becomes a mortal sin if it be done out of contempt. But it would seem impossible to commit even a venial sin, deliberately, without contempt. Since then the consent of the higher reason is always accompanied by deliberate consideration of the eternal law, it seems that it cannot be without mortal sin, on account of the contempt of the Divine law.

_On the contrary,_ Consent to a sinful act belongs to the higher reason, as stated above (A. 7). But consent to an act of venial sin is itself a venial sin. Therefore a venial sin can be in the higher reason.

_I answer that,_ As Augustine says (De Trin. xii, 7), the higher reason "is intent on contemplating or consulting the eternal law"; it contemplates it by considering its truth; it consults it by judging and directing other things according to it: and to this pertains the fact that by deliberating through the eternal types, it consents to an act or dissents from it. Now it may happen that the inordinateness of the act to which it consents, is not contrary to the eternal law, in the same way as mortal sin is, because it does not imply aversion from the last end, but is beside that law, as an act of venial sin is. Therefore when the higher reason consents to the act of a venial sin, it does not turn away from the eternal law: wherefore it sins, not mortally, but venially.

This suffices for the Reply to the First Objection.

Reply Obj. 2: Disease of the heart is twofold: one which is in the very substance of the heart, and affects its natural consistency, and such a disease is always mortal: the other is a disease of the heart consisting in some disorder either of the movement or of the parts surrounding the heart, and such a disease is not always mortal. In like manner there is mortal sin in the higher reason whenever the order itself of the higher reason to its proper object which is the eternal law, is destroyed; but when the disorder leaves this untouched, the sin is not mortal but venial.

Reply Obj. 3: Deliberate consent to a sin does not always amount to contempt of the Divine law, but only when the sin is contrary to the Divine law.

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 G.o.d, 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 G.o.d, 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 G.o.d. 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 G.o.d, 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 G.o.d 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.
