The prudential call here would seem to be the final check on my reasons for sharing this information. These judgments arise situation by situation. Prudence presumes good judgment which results from an accumulation of wisdom from experience, individually and collectively. It is no wonder our primary method of learning is in the group process experience where a live situation arises and is reflected upon in the setting, not written out in textbooks. Thirdly, an ethic of prudence comes down to the practical skills in reporting.
Language is primary here.
There are ways of saying things and there are ways of saying things. Whether verbal or written, there is a science to the way of reporting. Precision comes with practice. I don't believe there is anybody who could not benefit from some practice sessions on confidentiality. Perhaps this Fall, chaplains in a given geographical area might consider gathering for an evening to work with this issue of confidentiality.
