Whether covetousness is a spiritual sin?

Objections

Objection 1 : It seems that covetousness is not a spiritual sin. For spiritual sins seem to regard spiritual goods. But the matter of covetousness is bodily goods, namely, external riches. Therefore covetousness is not a spiritual sin.
Objection 2 : Further, spiritual sin is condivided with sin of the flesh. Now covetousness is seemingly a sin of the flesh, for it results from the corruption of the flesh, as instanced in old people who, through corruption of carnal nature, fall into covetousness. Therefore covetousness is not a spiritual sin.
Objection 3 : Further, a sin of the flesh is one by which man's body is disordered, according to the saying of the Apostle (1 Cor. 6:18), "He that committeth fornication sinneth against his own body." Now covetousness disturbs man even in his body; wherefore Chrysostom (Hom. xxix in Matth.) compares the covetous man to the man who was possessed by the devil (Mk. 5) and was troubled in body. Therefore covetousness seems not to be a spiritual sin.
