Whether it is necessary for one to confess to one's own priest?

Objections

Objection 1 : It would seem that it is nol necessary to confess to one's own priest. For Gregory [*Cf. Can. Ex auctoritate xvi, Question [1]] says: "By our apostolic authority and in discharge of our solicitude we have decreed that priests, who as monks imitate the ex. ample of the apostles, may preach, baptize, give communion, pray for sinners, impose penances, and absolve from sins." Now monks are not the proper priests of anyone, since they have not the care of souls. Since, therefore confession is made for the sake of absolution it suffices for it to be made to any priest.
Objection 2 : Further, the minister of this sacrament is a priest, as also of the Eucharist. But any priest can perform the Eucharist. Therefore any priest can administer the sacrament of Penance. Therefore there is no need to confess to one's own priest.
Objection 3 : Further, when we are bound to one thing in particular it is not left to our choice. But the choice of a discreet priest is left to us as appears from the authority of Augustine quoted in the text (Sent. ix, D, 17): for he says in De vera et falsa Poenitentia [*Work of an unknown author]: "He who wishes to confess his sins, in order to find grace, must seek a priest who knows how to loose and to bind." Therefore it seems unnecessary to confess to one's own priest.
Objection 4 : Further, there are some, such as prelates, who seem to have no priest of their own, since they have no superior: yet they are bound to confession. Therefore a man is not always bound to confess to his own priest.
Objection 5 : Further, "That which is instituted for the sake of charity, does not militate against charity," as Bernard observes (De Praecept. et Dispens. ii). Now confession, which was instituted for the sake of charity, would militate against charity, if a man were bound to confess to any particular priest: e.g. if the sinner know that his own priest is a heretic, or a man of evil influence, or weak and prone to the very sin that he wishes to confess to him, or reasonably suspected of breaking the seal of confession, or if the penitent has to confess a sin committed against his confessor. Therefore it seems that one need not always confess to one's own priest.
Objection 6 : Further, men should not be straitened in matters necessary for salvation, lest they be hindered in the way of salvation. But it seems a great inconvenience to be bound of necessity to confess to one particular man, and many might be hindered from going to confession, through either fear, shame, or something else of the kind. Therefore, since confession is necessary for salvation, men should not be straitened, as apparently they would be, by having to confess to their own priest.
