Catechism Section 1473
The forgiveness of sin and restoration of communion with God entail the remission of the eternal punishment
of sin, but temporal
punishment of sin remains. While patiently bearing sufferings and trials of all kinds and, when
the day comes, serenely
facing death, the Christian must strive to accept this temporal punishment of sin as a grace.
He should strive by
works of mercy and charity, as well as by prayer and the various practices of penance, to put
off completely the
"old man" and to put on the "new man."
