Wonderful article. You really explained this situation clearly and offered specific actions and questions we can use.
The only part that struck me as a little off was the line "If we believe firmly in our particular faith (and to be a good practitioners of our faith then we surely must!)". This seems to imply if you don't believe firmly in your faith then you're not a good practitioner of it. Doubt is usually at least some part of most believers faith practices, whether we're talking about nurses or patients.
