Reply to Objection 4: No man is bound to confess sins that he has no longer. Consequently, if a man has confessed to the bishop's penitentiary, or to someone else having faculties from the bishop, his sins are forgiven both before the Church and before God, so that he is not bound to confess them to his own priest, however much the latter may insist: but on account of the Ecclesiastical precept (De Poenit. et Remiss., Cap. Omnis utriusque) which prescribes confession to be made once a year to one's own priest, he is under the same obligation as one who has committed none but venial sins. For such a one, according to some, is bound to confess none but venial sins, or he must declare that he is free from mortal sin, and the priest, in the tribunal of conscience, ought, and is bound, to believe him. If, however, he were bound to confess again, his first confession would not be useless, because the more priests one confesses to, the more is the punishment remitted, both by reason of the shame in confessing, which is reckoned as a satisfactory punishment, and by reason of the power of the keys: so that one might confess so often as to be delivered from all punishment. Nor is repetition derogatory to a sacrament, except in those wherein there is some kind of sanctification, either by the impressing of a character, or by the consecration of the matter, neither of which applies to Penance. Hence it would be well for him who hears confessions by the bishop's authority, to advise the penitent to confess to his own priest, yet he must absolve him, even if he declines to do so.
