The forgiveness of sins committed after Baptism is conferred by a particular sacrament called the sacrament of conversion, confession, penance, or reconciliation. Only priests who have received the faculty of absolving from the authority of the Church can forgive sins in the name of Christ.
(Catechism of the Catholic Church, 1486; 1495).
The Sacrament of Reconciliation is available 30 mins prior to our masses or you can contact the Pastoral Center.
