Confidentiality
Things should be kept in secret when someone confides in you.
Someone might share information with you that is between you and they alone.
Priests, ministers, rabbis, counsellors, and doctors are required to keep information shared with them private and their prescribings and diagnoses private. However, the patients and confiders are allowed to share the diagnoses with whomever they choose.
The scripture speaks of wise counsel. If a person has spoken something to you, it is scriptural to seek Godly counsel on the matter when it is or seems troubling.
We know that it is common practice for people to share diagnoses after receiving it. If not for consolation but to gain better understanding. If you wish a conversation to remain private which involves a diagnosis, make it plain that the persons involved know they are to keep it silent. Otherwise, no breach of confidentiality has occurred.
