Whether carnal sins are of less guilt than spiritual sins?

Objections

Objection 1 : It would seem that carnal sins are not of less guilt than spiritual sins. Because adultery is a more grievous sin than theft: for it is written (Prov. 6:30,32): "The fault is not so great when a man has stolen . . . but he that is an adulterer, for the folly of his heart shall destroy his own soul." Now theft belongs to covetousness, which is a spiritual sin; while adultery pertains to lust, which is a carnal sin. Therefore carnal sins are of greater guilt than spiritual sins.
Objection 2 : Further, Augustine says in his commentary on Leviticus [*The quotation is from De Civ. Dei ii, 4 and iv, 31.] that "the devil rejoices chiefly in lust and idolatry." But he rejoices more in the greater sin. Therefore, since lust is a carnal sin, it seems that the carnal sins are of most guilt.
Objection 3 : Further, the Philosopher proves (Ethic. vii, 6) that "it is more shameful to be incontinent in lust than in anger." But anger is a spiritual sin, according to Gregory (Moral. xxxi, 17); while lust pertains to carnal sins. Therefore carnal sin is more grievous than spiritual sin.
