Reconciliation (also called Confession or Penance) is one of two Sacraments of Healing, along with the Anointing of the Sick.
In Reconciliation, a Catholic has the opportunity to talk about his or her shortcomings and sins with the priest and to hear Christ's words of forgiveness absolving them from their sin.
It is recommended that Catholics receive Reconciliation at least twice a year, usually during the seasons of Lent and Advent. At All Saints, Reconciliation is offered every Saturday afternoon in the Church at 3:30 pm.
