| 1490 The movement of return to God, called conversion and repentance, entails sorrow for and abhorrence of sins committed, and the firm purpose of sinning no more in the future. Conversion touches the past and the future and is nourished by hope in God's mercy. |
| 1491 The sacrament of Penance is a whole consisting in three actions of the penitent and the priest's absolution. The penitent's acts are repentance, confession or disclosure of sins to the priest, and the intention to make reparation and do works of reparation. |
