Whether an indulgence ought to be granted for temporal help?

Objections

Objection 1 : It would seem that an indulgence ought not to be granted for temporal help. Because the remission of sins is something spiritual. Now to exchange a spiritual for a temporal thing is simony. Therefore this ought not to be done.
Objection 2 : Further, spiritual assistance is more necessary than temporal. But indulgences do not appear to be granted for spiritual assistance. Much less therefore ought they to be granted for temporal help.
