One of the main strengths of the Canadian Forces chaplaincy is we that don't keep notes. We don't write reports on conversations we have. The level of confidentiality is significant within the legal bounds of confidentiality and counselling.
Regardless of rank, chaplains would move freely and become the sounding board for trauma, personal difficulties, marital disruptions, moral dilemmas, anger, and for distress with commanding officers or a superior or frustration with subordinates. Chaplains get it all and we're in a very privileged position to receive that information. Sometimes all that's necessary is to walk that individual through their event and the resolve. Other times we advocate for services they may need, or we may encourage them to come forward with a particular need.
