Whether one may confess through another, or by writing?

Objections

Objection 1 : It would seem that one may confess through another, or by writing. For confession is necessary in order that the penitent's conscience may be made known to the priest. But a man can make his conscience known to the priest, through another or by writing. Therefore it is enough to confess through another or by writing.
Objection 2 : Further, some are not understood by their own priests on account of a difference of language, and consequently cannot confess save through others. Therefore it is not essential to the sacrament that one should confess by oneself, so that if anyone confesses through another in any way whatever, it suffices for his salvation.
Objection 3 : Further, it is essential to the sacrament that a man should confess to his own priest, as appears from what has been said (Question [8], Article [5]). Now sometimes a man's own priest is absent, so that the penitent cannot speak to him with his own voice. But he could make his conscience known to him by writing. Therefore it seems that he ought to manifest his conscience to him by writing to him.
