Any advice for dealing with a higher grade officer, not in my command, who is constantly trying to "help" but actually causing more problems?

LCDR (Join to see) - Then, Sir, I would suggest Plan B, where you have someone of equal or higher rank speak with that individual......if possible, that is.

I agree with SSG Livingston and don’t give up on all the considerate field grades out there...there are a few;)

Also, I’ve dealt with this before and with success. I chose to discuss the issue with my boss and he in turn found a round about way to get this officer to back down a bit. I think my boss told this officer that if he wanted to recommend something to our department, that he should contact him first.

Maj (Join to see) - Thanks. This is more of a case of this officer taking it upon themselves to be a mentor to me but the advice they are giving goes against every other piece of advice I've gotten from every other chaplain I've ever spoken to.

Also, my boss, the command chaplain, retires soon and the billet will be gapped for an undetermined period, so I'll be the acting command chaplain. This other chaplain will then be the senior ranking chaplain on the base.

Not quite an appropriate response for a chaplain. However, my human nature and my prior life in the Army makes me a little tempted. :)
