Whether covetousness is a sin?

❌ Objection 1 : It seems that covetousness is not aa sin. For covetousness [avaritia] denotes a certain greed for gold [aeris aviditas*], because, to wit, it consists in a desire for money, under which all external goods may be comprised. [*The Latin for covetousness "avaritia" is derived from "aveo" to desire; but the Greek {philargyria} signifies literally "love of money": and it is to this that St. Thomas is alluding (cf. Article [2], Objection [2])]. Now it is not a sin to desire external goods: since man desires them naturally, both because they are naturally subject to man, and because by their means man's life is sustained (for which reason they are spoken of as his substance). Therefore covetousness is not a sin.

❌ Objection 2 : Further, every sin is against either God, or one's neighbor, or oneself, as stated above (FS, Question [72], Article [4]). But covetousness is not, properly speaking, a sin against God: since it is opposed neither to religion nor to the theological virtues, by which man is directed to God. Nor again is it a sin against oneself, for this pertains properly to gluttony and lust, of which the Apostle says (1 Cor. 6:18): "He that committeth fornication sinneth against his own body." In like manner neither is it apparently a sin against one's neighbor, since a man harms no one by keeping what is his own. Therefore covetousness is not a sin.

❌ Objection 3 : Further, things that occur naturally are not sins. Now covetousness comes naturally to old age and every kind of defect, according to the Philosopher (Ethic. iv, 1). Therefore covetousness is not a sin.
