Part II (Pars Prima Secundae) Part 111 (1/2)

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?

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.
