Reply Obj. 1: Nothing hinders one thing from standing above another simply, and below it in some respect. Now a thing is deemed above another simply if it surpa.s.ses it in a point which is proper to both; while it is deemed above it in a certain respect, if it surpa.s.ses it in something which is accidental to both. Now it has been shown from the very nature of act and habit, that act surpa.s.ses habit both in goodness and in badness. Whereas the fact that habit is more lasting than act, is accidental to them, and is due to the fact that they are both found in a nature such that it cannot always be in action, and whose action consists in a transient movement. Consequently act simply excels in goodness and badness, but habit excels in a certain respect.
Reply Obj. 2: A habit is several acts, not simply, but in a certain respect, i.e. virtually. Wherefore this does not prove that habit precedes act simply, both in goodness and in badness.
Reply Obj. 3: Habit causes act by way of efficient causality: but act causes habit, by way of final causality, in respect of which we consider the nature of good and evil. Consequently act surpa.s.ses habit both in goodness and in badness.

Whether Sin Is Compatible with Virtue?
Objection 1: It would seem that a vicious act, i.e. sin, is incompatible with virtue. For contraries cannot be together in the same subject. Now sin is, in some way, contrary to virtue, as stated above (A. 1). Therefore sin is incompatible with virtue.
Obj. 2: Further, sin is worse than vice, i.e. evil act than evil habit. But vice cannot be in the same subject with virtue: neither, therefore, can sin.
Obj. 3: Further, sin occurs in natural things, even as in voluntary matters (Phys. ii, text. 82). Now sin never happens in natural things, except through some corruption of the natural power; thus monsters are due to corruption of some elemental force in the seed, as stated in _Phys._ ii. Therefore no sin occurs in voluntary matters, except through the corruption of some virtue in the soul: so that sin and virtue cannot be together in the same subject.
_On the contrary,_ The Philosopher says (Ethic. ii, 2, 3) that "virtue is engendered and corrupted by contrary causes." Now one virtuous act does not cause a virtue, as stated above (Q. 51, A. 3): and, consequently, one sinful act does not corrupt virtue. Therefore they can be together in the same subject.
_I answer that,_ Sin is compared to virtue, as evil act to good habit.
Now the position of a habit in the soul is not the same as that of a form in a natural thing. For the form of a natural thing produces, of necessity, an operation befitting itself; wherefore a natural form is incompatible with the act of a contrary form: thus heat is incompatible with the act of cooling, and lightness with downward movement (except perhaps violence be used by some extrinsic mover): whereas the habit that resides in the soul, does not, of necessity, produce its operation, but is used by man when he wills. Consequently man, while possessing a habit, may either fail to use the habit, or produce a contrary act; and so a man having a virtue may produce an act of sin. And this sinful act, so long as there is but one, cannot corrupt virtue, if we compare the act to the virtue itself as a habit: since, just as habit is not engendered by one act, so neither is it destroyed by one act as stated above (Q. 63, A. 2, ad 2). But if we compare the sinful act to the cause of the virtues, then it is possible for some virtues to be destroyed by one sinful act. For every mortal sin is contrary to charity, which is the root of all the infused virtues, as virtues; and consequently, charity being banished by one act of mortal sin, it follows that all the infused virtues are expelled _as virtues._ And I say [this] on account of faith and hope, whose habits remain unquickened after mortal sin, so that they are no longer virtues. On the other hand, since venial sin is neither contrary to charity, nor banishes it, as a consequence, neither does it expel the other virtues. As to the acquired virtues, they are not destroyed by one act of any kind of sin.
Accordingly, mortal sin is incompatible with the infused virtues, but is consistent with acquired virtue: while venial sin is compatible with virtues, whether infused or acquired.
Reply Obj. 1: Sin is contrary to virtue, not by reason of itself, but by reason of its act. Hence sin is incompatible with the act, but not with the habit, of virtue.
Reply Obj. 2: Vice is directly contrary to virtue, even as sin to virtuous act: and so vice excludes virtue, just as sin excludes acts of virtue.
Reply Obj. 3: The natural powers act of necessity, and hence so long as the power is unimpaired, no sin can be found in the act. On the other hand, the virtues of the soul do not produce their acts of necessity; hence the comparison fails.

FIFTH ARTICLE [I-II, Q. 71, Art. 5]
Whether Every Sin Includes an Action?
Objection 1: It would seem that every sin includes an action. For as merit is compared with virtue, even so is sin compared with vice. Now there can be no merit without an action. Neither, therefore, can there be sin without action.
Obj. 2: Further, Augustine says (De Lib. Arb. iii, 18) [*Cf. De Vera Relig. xiv.]: So "true is it that every sin is voluntary, that, unless it be voluntary, it is no sin at all." Now nothing can be voluntary, save through an act of the will. Therefore every sin implies an act.
Obj. 3: Further, if sin could be without act, it would follow that a man sins as soon as he ceases doing what he ought. Now he who never does something that he ought to do, ceases continually doing what he ought. Therefore it would follow that he sins continually; and this is untrue. Therefore there is no sin without an act.
_On the contrary,_ It is written (James 4:17): "To him ... who knoweth to do good, and doth it not, to him it is a sin." Now "not to do" does not imply an act. Therefore sin can be without act.
_I answer that,_ The reason for urging this question has reference to the sin of omission, about which there have been various opinions.
For some say that in every sin of omission there is some act, either interior or exterior--interior, as when a man wills _not to go to church,_ when he is bound to go--exterior, as when a man, at the very hour that he is bound to go to church (or even before), occupies himself in such a way that he is hindered from going. This seems, in a way, to amount to the same as the first, for whoever wills one thing that is incompatible with this other, wills, consequently, to go without this other: unless, perchance, it does not occur to him, that what he wishes to do, will hinder him from that which he is bound to do, in which case he might be deemed guilty of negligence.
On the other hand, others say, that a sin of omission does not necessarily suppose an act: for the mere fact of not doing what one is bound to do is a sin.
Now each of these opinions has some truth in it. For if in the sin of omission we look merely at that in which the essence of the sin consists, the sin of omission will be sometimes with an interior act, as when a man wills _not to go to church:_ while sometimes it will be without any act at all, whether interior or exterior, as when a man, at the time that he is bound to go to church, does not think of going or not going to church.
If, however, in the sin of omission, we consider also the causes, or occasions of the omission, then the sin of omission must of necessity include some act. For there is no sin of omission, unless we omit what we can do or not do: and that we turn aside so as not to do what we can do or not do, must needs be due to some cause or occasion, either united with the omission or preceding it. Now if this cause be not in man"s power, the omission will not be sinful, as when anyone omits going to church on account of sickness: but if the cause or occasion be subject to the will, the omission is sinful; and such cause, in so far as it is voluntary, must needs always include some act, at least the interior act of the will: which act sometimes bears directly on the omission, as when a man wills _not to go to church,_ because it is too much trouble; and in this case this act, of its very nature, belongs to the omission, because the volition of any sin whatever, pertains, of itself, to that sin, since voluntariness is essential to sin. Sometimes, however, the act of the will bears directly on something else which hinders man from doing what he ought, whether this something else be united with the omission, as when a man wills to play at the time he ought to go to church--or, precede the omission, as when a man wills to sit up late at night, the result being that he does not go to church in the morning. In this case the act, interior or exterior, is accidental to the omission, since the omission follows outside the intention, and that which is outside the intention is said to be accidental (Phys. ii, text. 49, 50). Wherefore it is evident that then the sin of omission has indeed an act united with, or preceding the omission, but that this act is accidental to the sin of omission.
Now in judging about things, we must be guided by that which is proper to them, and not by that which is accidental: and consequently it is truer to say that a sin can be without any act; else the circ.u.mstantial acts and occasions would be essential to other actual sins.
Reply Obj. 1: More things are required for good than for evil, since "good results from a whole and entire cause, whereas evil results from each single defect," as Dionysius states (Div. Nom. iv): so that sin may arise from a man doing what he ought not, or by his not doing what he ought; while there can be no merit, unless a man do willingly what he ought to do: wherefore there can be no merit without act, whereas there can be sin without act.
Reply Obj. 2: The term "voluntary" is applied not only to that on which the act of the will is brought to bear, but also to that which we have the power to do or not to do, as stated in _Ethic._ iii, 5.
Hence even not to will may be called voluntary, in so far as man has it in his power to will, and not to will.
Reply Obj. 3: The sin of omission is contrary to an affirmative precept which binds always, but not for always. Hence, by omitting to act, a man sins only for the time at which the affirmative precept binds him to act.

SIXTH ARTICLE [I-II, Q. 71, Art. 6]
Whether Sin Is Fittingly Defined As a Word, Deed, or Desire Contrary to the Eternal Law?
Objection 1: It would seem that sin is unfittingly defined by saying: "Sin is a word, deed, or desire, contrary to the eternal law."
Because "word," "deed," and "desire" imply an act; whereas not every sin implies an act, as stated above (A. 5). Therefore this definition does not include every sin.
Obj. 2: Further, Augustine says (De Duab. Anim. xii): "Sin is the will to retain or obtain what justice forbids." Now will is comprised under desire, in so far as desire denotes any act of the appet.i.te.
Therefore it was enough to say: "Sin is a desire contrary to the eternal law," nor was there need to add "word" or "deed."
Obj. 3: Further, sin apparently consists properly in aversion from the end: because good and evil are measured chiefly with regard to the end as explained above (Q. 1, A. 3; Q. 18, AA. 4, 6; Q. 20, AA.
2, 3): wherefore Augustine (De Lib. Arb. i) defines sin in reference to the end, by saying that "sin is nothing else than to neglect eternal things, and seek after temporal things": and again he says (Qq. lx.x.xii, qu. 30) that "all human wickedness consists in using what we should enjoy, and in enjoying what we should use." Now the definition in question contains no mention of aversion from our due end: therefore it is an insufficient definition of sin.
Obj. 4: Further, a thing is said to be forbidden, because it is contrary to the law. Now not all sins are evil through being forbidden, but some are forbidden because they are evil. Therefore sin in general should not be defined as being against the law of G.o.d.
Obj. 5: Further, a sin denotes a bad human act, as was explained above (A. 1). Now man"s evil is to be against reason, as Dionysius states (Div. Nom. iv). Therefore it would have been better to say that sin is against reason than to say that it is contrary to the eternal law.
_On the contrary,_ the authority of Augustine suffices (Contra Faust.
xxii, 27).
_I answer that,_ As was shown above (A. 1), sin is nothing else than a bad human act. Now that an act is a human act is due to its being voluntary, as stated above (Q. 1, A. 1), whether it be voluntary, as being elicited by the will, e.g. to will or to choose, or as being commanded by the will, e.g. the exterior actions of speech or operation. Again, a human act is evil through lacking conformity with its due measure: and conformity of measure in a thing depends on a rule, from which if that thing depart, it is incommensurate. Now there are two rules of the human will: one is proximate and h.o.m.ogeneous, viz. the human reason; the other is the first rule, viz.
the eternal law, which is G.o.d"s reason, so to speak. Accordingly Augustine (Contra Faust. xxii, 27) includes two things in the definition of sin; one, pertaining to the substance of a human act, and which is the matter, so to speak, of sin, when he says "word, deed, or desire"; the other, pertaining to the nature of evil, and which is the form, as it were, of sin, when he says, "contrary to the eternal law."
Reply Obj. 1: Affirmation and negation are reduced to one same genus: e.g. in Divine things, begotten and unbegotten are reduced to the genus "relation," as Augustine states (De Trin. v, 6, 7): and so "word" and "deed" denote equally what is said and what is not said, what is done and what is not done.
Reply Obj. 2: The first cause of sin is in the will, which commands all voluntary acts, in which alone is sin to be found: and hence it is that Augustine sometimes defines sin in reference to the will alone. But since external acts also pertain to the substance of sin, through being evil of themselves, as stated, it was necessary in defining sin to include something referring to external action.
Reply Obj. 3: The eternal law first and foremost directs man to his end, and in consequence, makes man to be well disposed in regard to things which are directed to the end: hence when he says, "contrary to the eternal law," he includes aversion from the end and all other forms of inordinateness.
Reply Obj. 4: When it is said that not every sin is evil through being forbidden, this must be understood of prohibition by positive law. If, however, the prohibition be referred to the natural law, which is contained primarily in the eternal law, but secondarily in the natural code of the human reason, then every sin is evil through being prohibited: since it is contrary to natural law, precisely because it is inordinate.
Reply Obj. 5: The theologian considers sin chiefly as an offense against G.o.d; and the moral philosopher, as something contrary to reason. Hence Augustine defines sin with reference to its being "contrary to the eternal law," more fittingly than with reference to its being contrary to reason; the more so, as the eternal law directs us in many things that surpa.s.s human reason, e.g. in matters of faith.
