We must now consider the debt of punishment.
We shall consider (1) the debt itself; (2) mortal and venial sin, which differ in respect of the punishment due to them.
Under the first head there are eight points of inquiry:
A Whether the debt of punishment is an effect of sin?
A Whether one sin can be the punishment of another?
A Whether any sin incurs a debt of eternal punishment?
A Whether sin incurs a debt of punishment that is infinite in quantity?
A Whether every sin incurs a debt of eternal and infinite punishment?
A Whether the debt of punishment can remain after sin?
A Whether every punishment is inflicted for a sin?
A Whether one person can incur punishment for another's sin?
