There are four steps in the Sacrament of Reconciliation:
Sin hurts our relationship with God, ourselves and others. As the Catechism states:
Monday -Friday confessions are held in the Chapel
Saturday confessions are held in the Cathedral
The sinner wounds God’s honor and love, his own human dignity…and the spiritual well-being of the Church, of which each Christian ought to be a living stone. To the eyes of faith no evil is graver than sin and nothing has worse consequences for the sinners themselves, for the Church, and for the whole world. (CCC 1487, 1488)
