In the language of the Handbook, the power of "no" is something like "shalt not", "should not" and "not generally", with the latter as being fairly weak.leidasolo wrote:"Because stake presidencies and bishoprics are responsible for all members of the stake or ward, these brethren are not generally assigned as ministering brothers to specific individuals or families."
To me "not generally" isn't the same as "the function will not be available in LCR". I can see why a bishop would want a specific member assigned to him (or one of the bishopric). The bishop might have a reason for not having them be assigned to someone else and there isn't any other way to classify the person in such a way as to prevent them from being assigned. (Unassigned for a reason.)
In other words, I can understand the logic of not assigning the bishopric to the general pool of Ministers, but doesn't exclude the idea of having specific families assigned to them to accomodate special situations. To me, that's still in harmony with the directive quoted above.
However, the stake president does have the keys of interpretation for his units. If you have any special situations, it might be worth talking to him about that.
