The Irish... developed a form of confession that was exclusively private and that had no equivalent on the continent. In the ancient church, confession of one's sins—and the subsequent penance... had always been public.... one did not necessarily choose one's "priest" from among ordained professionals: the act of confession was too personal and too important for such a limitation. One looked for an anmchara, a soul-friend, someone to be trusted over a whole lifetime.
