Whether the debt of punishment remains after the guilt has been forgiven through Penance?

Objections

Objection 1 : It would seem that no debt of punishment remains after the guilt has been forgiven through Penance. For when the cause is removed, the effect is removed. But the guilt is the cause of the debt of punishment: since a man deserves to be punished because he has been guilty of a sin. Therefore when the sin has been forgiven, no debt of punishment can remain.
Objection 2 : Further, according to the Apostle (Rm. 5) the gift of Christ is more effective than the sin of Adam. Now, by sinning, man incurs at the same time guilt and the debt of punishment. Much more therefore, by the gift of grace, is the guilt forgiven and at the same time the debt of punishment remitted.
Objection 3 : Further, the forgiveness of sins is effected in Penance through the power of Christ's Passion, according to Rm. 3:25: "Whom God hath proposed to be a propitiation, through faith in His Blood . . . for the remission of former sins." Now Christ's Passion made satisfaction sufficient for all sins, as stated above (Questions [48],49,79, Article [5]). Therefore after the guilt has been pardoned, no debt of punishment remains.
