Whether covetousness is the greatest of sins?

Objections

Objection 1 : It seems that covetousness is the greatest of sins. For it is written (Ecclus. 10:9): "Nothing is more wicked than a covetous man," and the text continues: "There is not a more wicked thing than to love money: for such a one setteth even his own soul to sale." Tully also says (De Offic. i, under the heading, 'True magnanimity is based chiefly on two things'): "Nothing is so narrow or little minded as to love money." But this pertains to covetousness. Therefore covetousness is the most grievous of sins.
Objection 2 : Further, the more a sin is opposed to charity, the more grievous it is. Now covetousness is most opposed to charity: for Augustine says (Questions [83], qu. 36) that "greed is the bane of charity." Therefore covetousness is the greatest of sins.
Objection 3 : Further, the gravity of a sin is indicated by its being incurable: wherefore the sin against the Holy Ghost is said to be most grievous, because it is irremissible. But covetousness is an incurable sin: hence the Philosopher says (Ethic. iv, 1) that "old age and helplessness of any kind make men illiberal." Therefore covetousness is the most grievous of sins.
Objection 4 : Further, the Apostle says (Eph. 5:5) that covetousness is "a serving of idols." Now idolatry is reckoned among the most grievous sins. Therefore covetousness is also.
