What is Confessor?

Legal Definition
Evid. A priest of some Christian sect, who receives an account of the sins of his people, and undertakes to give them absolution of their sins.

2. The general rule on the subject of giving evidence of confidential communications is, that the privilege is confined to counsel, solicitors, and attorneys, and the interpreter between the counsel and the client. Vide Confidential Communications. Contrary to this general rule, it has been decided in New York, that a priest of the Roman Catholic denomination could not be compelled to divulge secrets which he had received in auricular confession. 2 City Hall Rec. 80, n.; Joy on Conf. 4, p. 49. See Bouv. Inst. n. 3174 and note.
