I agree with the main point of the O.P but more often than not the "window washer" bit has been used to describe how absolutely bereft of training the Elders are for their pastoral Role. They are trained how to "discipline", how to protect the Org, but not how to really care for the "sheep".
I think of one case, where they were dealing with a young man, married and working, but he had got badly in to debt, the Elders pulled him in and "disciplined" him for another matter, and he walked in to the sea and drowned himself a couple of days later.
Had they been qualified as Counsellors, and were really loving Shepherds, he would more than likely be alive today.
