Whether the whole of this life is the time for contrition?

Objections

Objection 1 : It would seem that the time for contrition is not the whole of this life. For as we should be sorry for a sin committed, so should we be ashamed of it. But shame for sin does not last all one's life, for Ambrose says (De Poenit. ii) that "he whose sin is forgiven has nothing to be ashamed of." Therefore it seems that neither should contrition last all one's life, since it is sorrow for sin.
Objection 2 : Further, it is written (1 Jn. 4:18) that "perfect charity casteth out fear, because fear hath pain." But sorrow also has pain. Therefore the sorrow of contrition cannot remain in the state of perfect charity.
Objection 3 : Further, there cannot be any sorrow for the past (since it is, properly speaking, about a present evil) except in so far as something of the past sin remains in the present time. Now, in this life, sometimes one attains to a state in which nothing remains of a past sin, neither disposition, nor guilt, nor any debt of punishment. Therefore there is no need to grieve any more for that sin.
Objection 4 : Further, it is written (Rm. 8:28) that "to them that love God all things work together unto good," even sins as a gloss declares [*Augustine, De Correp. et Grat.]. Therefore there is no need for them to grieve for sin after it has been forgiven.
Objection 5 : Further, contrition is a part of Penance, condivided with satisfaction. But there is no need for continual satisfaction. Therefore contrition for sin need not be continual.
