"Confess your sins to one another, and pray for one another, that you may be healed"
Sin is before all else an offense against God, a rupture of communion with him. At the same time it damages communion with the Church. For this reason conversion entails both God's forgiveness and reconciliation with the Church, which are expressed and accomplished liturgically by the sacrament of Penance and Reconciliation. ˜Catechism of the Catholic Church
