Are priests bound by confidentiality?
Also asked, are pastors bound by confidentiality?
The duty of confidentiality applies in all contexts and is an ethical matter every minister must navigate carefully. A minister's duty of confidentiality is breached when they disclose confidences to anyone, anywhere. Of those, only three of the cases found the minister civilly liable for sharing confidences.
Also to know, can a priest ever break the seal of confession?
Under Roman Catholic law, it is forbidden for a priest to disclose information — under any circumstances — obtained in the form of religious confession. If a priest breaks what's called "the sacred seal of confession," he will be subject to excommunication from the church.
If you had told the priest that you had murdered someone, as part of the sacramental act of confession, in which the priest had agreed to provide you with that act, the priest would tell no one. The Catholic church is very strict on that point. No exception is allowed.
