We must now consider the distinction of sins or vices: under which head there are nine points of inquiry:
(1) Whether sins are distinguished specifically by their objects?
(2) Of the distinction between spiritual and carnal sins;
(3) Whether sins differ in reference to their causes?
(4) Whether they differ with respect to those who are sinned against?
(5) Whether sins differ in relation to the debt of punishment?
(6) Whether they differ in regard to omission and commission?
(7) Whether they differ according to their various stages?
(8) Whether they differ in respect of excess and deficiency?
(9) Whether they differ according to their various circ.u.mstances?

FIRST ARTICLE [I-II, Q. 72, Art. 1]
Whether Sins Differ in Species According to Their Objects?
Objection 1: It would seem that sins do not differ in species, according to their objects. For acts are said to be good or evil, in relation, chiefly, to their end, as shown above (Q. 1, A. 3; Q. 18, AA. 4, 6). Since then sin is nothing else than a bad human act, as stated above (Q. 71, A. 1), it seems that sins should differ specifically according to their ends rather than according to their objects.
Obj. 2: Further, evil, being a privation, differs specifically according to the different species of opposites. Now sin is an evil in the genus of human acts. Therefore sins differ specifically according to their opposites rather than according to their objects.
Obj. 3: Further, if sins differed specifically according to their objects, it would be impossible to find the same specific sin with diverse objects: and yet such sins are to be found. For pride is about things spiritual and material as Gregory says (Moral. x.x.xiv, 18); and avarice is about different kinds of things. Therefore sins do not differ in species according to their objects.
_On the contrary,_ "Sin is a word, deed, or desire against G.o.d"s law." Now words, deeds, and desires differ in species according to their various objects: since acts differ by their objects, as stated above (Q. 18, A. 2). Therefore sins, also differ in species according to their objects.
_I answer that,_ As stated above (Q. 71, A. 6), two things concur in the nature of sin, viz. the voluntary act, and its inordinateness, which consists in departing from G.o.d"s law. Of these two, one is referred essentially to the sinner, who intends such and such an act in such and such matter; while the other, viz. the inordinateness of the act, is referred accidentally to the intention of the sinner, for "no one acts intending evil," as Dionysius declares (Div. Nom. iv).
Now it is evident that a thing derives its species from that which is essential and not from that which is accidental: because what is accidental is outside the specific nature. Consequently sins differ specifically on the part of the voluntary acts rather than of the inordinateness inherent to sin. Now voluntary acts differ in species according to their objects, as was proved above (Q. 18, A. 2).
Therefore it follows that sins are properly distinguished in species by their objects.
Reply Obj. 1: The aspect of good is found chiefly in the end: and therefore the end stands in the relation of object to the act of the will which is at the root of every sin. Consequently it amounts to the same whether sins differ by their objects or by their ends.
Reply Obj. 2: Sin is not a pure privation but an act deprived of its due order: hence sins differ specifically according to the objects of their acts rather than according to their opposites, although, even if they were distinguished in reference to their opposite virtues, it would come to the same: since virtues differ specifically according to their objects, as stated above (Q. 60, A. 5).
Reply Obj. 3: In various things, differing in species or genus, nothing hinders our finding one formal aspect of the object, from which aspect sin receives its species. It is thus that pride seeks excellence in reference to various things; and avarice seeks abundance of things adapted to human use.

SECOND ARTICLE [I-II, Q. 72, Art. 2]
Whether Spiritual Sins Are Fittingly Distinguished from Carnal Sins?
Objection 1: It would seem that spiritual sins are unfittingly distinguished from carnal sins. For the Apostle says (Gal. 5:19): "The works of the flesh are manifest, which are fornication, uncleanness, immodesty, luxury, idolatry, witchcrafts," etc. from which it seems that all kinds of sins are works of the flesh. Now carnal sins are called works of the flesh. Therefore carnal sins should not be distinguished from spiritual sins.
Obj. 2: Further, whosoever sins, walks according to the flesh, as stated in Rom. 8:13: "If you live according to the flesh, you shall die. But if by the spirit you mortify the deeds of the flesh, you shall live." Now to live or walk according to the flesh seems to pertain to the nature of carnal sin. Therefore carnal sins should not be distinguished from spiritual sins.
Obj. 3: Further, the higher part of the soul, which is the mind or reason, is called the spirit, according to Eph. 4:23: "Be renewed in the spirit of your mind," where spirit stands for reason, according to a gloss. Now every sin, which is committed in accordance with the flesh, flows from the reason by its consent; since consent in a sinful act belongs to the higher reason, as we shall state further on (Q. 74, A. 7). Therefore the same sins are both carnal and spiritual, and consequently they should not be distinguished from one another.
Obj. 4: Further, if some sins are carnal specifically, this, seemingly, should apply chiefly to those sins whereby man sins against his own body. But, according to the Apostle (1 Cor. 6:18), "every sin that a man doth, is without the body: but he that committeth fornication, sinneth against his own body." Therefore fornication would be the only carnal sin, whereas the Apostle (Eph.
5:3) reckons covetousness with the carnal sins.
_On the contrary,_ Gregory (Moral. x.x.xi, 17) says that "of the seven capital sins five are spiritual, and two carnal."
_I answer that,_ As stated above (A. 1), sins take their species from their objects. Now every sin consists in the desire for some mutable good, for which man has an inordinate desire, and the possession of which gives him inordinate pleasure. Now, as explained above (Q. 31, A. 3), pleasure is twofold. One belongs to the soul, and is consummated in the mere apprehension of a thing possessed in accordance with desire; this can also be called spiritual pleasure, e.g. when one takes pleasure in human praise or the like. The other pleasure is bodily or natural, and is realized in bodily touch, and this can also be called carnal pleasure.
Accordingly, those sins which consist in spiritual pleasure, are called spiritual sins; while those which consist in carnal pleasure, are called carnal sins, e.g. gluttony, which consists in the pleasures of the table; and l.u.s.t, which consists in s.e.xual pleasures.
Hence the Apostle says (2 Cor. 7:1): "Let us cleanse ourselves from all defilement of the flesh and of the spirit."
Reply Obj. 1: As a gloss says on the same pa.s.sage, these vices are called works of the flesh, not as though they consisted in carnal pleasure; but flesh here denotes man, who is said to live according to the flesh, when he lives according to himself, as Augustine says (De Civ. Dei xiv, 2, 3). The reason of this is because every failing in the human reason is due in some way to the carnal sense.
This suffices for the Reply to the Second Objection.
Reply Obj. 3: Even in the carnal sins there is a spiritual act, viz.
the act of reason: but the end of these sins, from which they are named, is carnal pleasure.
Reply Obj. 4: As the gloss says, "in the sin of fornication the soul is the body"s slave in a special sense, because at the moment of sinning it can think of nothing else": whereas the pleasure of gluttony, although carnal, does not so utterly absorb the reason. It may also be said that in this sin, an injury is done to the body also, for it is defiled inordinately: wherefore by this sin alone is man said specifically to sin against his body. While covetousness, which is reckoned among the carnal sins, stands here for adultery, which is the unjust appropriation of another"s wife. Again, it may be said that the thing in which the covetous man takes pleasure is something bodily, and in this respect covetousness is numbered with the carnal sins: but the pleasure itself does not belong to the body, but to the spirit, wherefore Gregory says (Moral. x.x.xi, 17) that it is a spiritual sin.

THIRD ARTICLE [I-II, Q. 72, Art. 3]
Whether Sins Differ Specifically in Reference to Their Causes?
Objection 1: It would seem that sins differ specifically in reference to their causes. For a thing takes its species from that whence it derives its being. Now sins derive their being from their causes.
Therefore they take their species from them also. Therefore they differ specifically in reference to their causes.
Obj. 2: Further, of all the causes the material cause seems to have least reference to the species. Now the object in a sin is like its material cause. Since, therefore, sins differ specifically according to their objects, it seems that much more do they differ in reference to their other causes.
Obj. 3: Further, Augustine, commenting on Ps. 79:17, "Things set on fire and dug down," says that "every sin is due either to fear inducing false humility, or to love enkindling us to undue ardor."
For it is written (1 John 2:16) that "all that is in the world, is the concupiscence of the flesh, or [Vulg.: "and"] the concupiscence of the eyes, or [Vulg.: "and"] the pride of life." Now a thing is said to be in the world on account of sin, in as much as the world denotes lovers of the world, as Augustine observes (Tract. ii in Joan.). Gregory, too (Moral. x.x.xi, 17), distinguishes all sins according to the seven capital vices. Now all these divisions refer to the causes of sins. Therefore, seemingly, sins differ specifically according to the diversity of their causes.
_On the contrary,_ If this were the case all sins would belong to one species, since they are due to one cause. For it is written (Ecclus.
10:15) that "pride is the beginning of all sin," and (1 Tim. 6:10) that "the desire of money is the root of all evils." Now it is evident that there are various species of sins. Therefore sins do not differ specifically according to their different causes.
_I answer that,_ Since there are four kinds of causes, they are attributed to various things in various ways. Because the _formal_ and the _material_ cause regard properly the substance of a thing; and consequently substances differ in respect of their matter and form, both in species and in genus. The _agent_ and the _end_ regard directly movement and operation: wherefore movements and operations differ specifically in respect of these causes; in different ways, however, because the natural active principles are always determined to the same acts; so that the different species of natural acts are taken not only from the objects, which are the ends or terms of those acts, but also from their active principles: thus heating and cooling are specifically distinct with reference to hot and cold. On the other hand, the active principles in voluntary acts, such as the acts of sins, are not determined, of necessity, to one act, and consequently from one active or motive principle, diverse species of sins can proceed: thus from fear engendering false humility man may proceed to theft, or murder, or to neglect the flock committed to his care; and these same things may proceed from love enkindling to undue ardor. Hence it is evident that sins do not differ specifically according to their various active or motive causes, but only in respect of diversity in the final cause, which is the end and object of the will. For it has been shown above (Q. 1, A. 3; Q. 18, AA. 4, 6) that human acts take their species from the end.
Reply Obj. 1: The active principles in voluntary acts, not being determined to one act, do not suffice for the production of human acts, unless the will be determined to one by the intention of the end, as the Philosopher proves (Metaph. ix, text. 15, 16), and consequently sin derives both its being and its species from the end.
Reply Obj. 2: Objects, in relation to external acts, have the character of matter "about which"; but, in relation to the interior act of the will, they have the character of end; and it is owing to this that they give the act its species. Nevertheless, even considered as the matter "about which," they have the character of term, from which movement takes its species (Phys. v, text. 4; _Ethic._ x, 4); yet even terms of movement specify movements, in so far as term has the character of end.
Reply Obj. 3: These distinctions of sins are given, not as distinct species of sins, but to show their various causes.
