“The Church says covetousness is a deadly sin” but does she really think so? Is she ready to found welfare societies to deal with financial immorality as she does with sexual immorality,” Sayers mused, rhetorically asking “does the Church arrange services, with bright congregational singing, for total abstainers from usury?”
In the same vein, she upbraided contemporary society for a related sin. “Whether or not it is desirable to keep up this fearful whirligig of industrial finance based on gluttonous consumption,” she asserted, “it could not be kept up for a minute without the co-operative gluttony of the consumer.” Sayers would have agreed that the housing meltdown was, at base, a moral failure. The belief that it was not merely reasonable, but virtuous, to want that which you could not afford would have struck her as preposterous as well as sinful.
