What does Martin Luther think is a better use of the money spent on indulgences?

-''Committed to the idea that salvation could be reached through faith and by divine grace only, Luther vigorously objected to the corrupt practice of selling indulgences.''

-"He argued that the practice of relying on indulgences drew believers away from the one true source of salvation: faith in Christ. God alone had the power to pardon the repentant faithful. The pontifical council ordered him to retract his claims immediately, but Luther refused."
