All may, none must, some should.
Saturdays at 12:30 noon
A priest is available to hear confessions every Saturday after the noon mass. If you wish to give your confession, speak with the priest celebrating the mass. For those who have never given their confession, the priest will shepherd the penitent through the rite. The Rite of Reconciliation in the Book of Common Prayer begins on page 447. Confessions may also be heard by appointment.
From the Book of Common Prayer
The ministry of reconciliation, which has been committed by Christ to his Church, is exercised through the care each Christian has for others, through the common prayer of Christians assembled for public worship, and through the priesthood of Christ and his ministers declaring
The Reconciliation of a Penitent is available for all who desire it. It is not restricted to times of sickness. Confessions may be heard anytime and anywhere. . . .
When the penitent has confessed all serious sins troubling the conscience and has given evidence of due contrition, the priest gives such counsel and encouragement as are needed and pronounces the absolution. Before giving absolution, the priest may assign to the penitent a psalm, prayer, or hymn to be said, or something to be done, as a sign of penitence and act of thanksgiving.
The content of a confession is not normally a matter of subsequent discussion. The secrecy of a confession is morally absolute for the confessor, and must under no circumstances be broken.
