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.

❌ Objection 2 : Further, whosoever sins, walks according to the flesh, as stated in Rm. 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.

❌ Objection 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 (Question [74], Article [7]). Therefore the same sins are both carnal and spiritual, and consequently they should not be distinguished from one another.

❌ Objection 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.
