I will give you a personal one. Among other things this person is in charge of altar servers at my parish. Thankfully I’m grandfathered and do not fall under her dominion. This incident happened while my parish was between pastors several years ago.
A guy from the Scripture study program I was involved with wanted to learn how to serve Mass with all the “bells and smells” so that he could do so for his out-of-town best friend that was going to be married at our parish.
Knowing it was only for this Mass (he was close to graduating from college and moving on) and knowing this problem person had no jurisdiction over nuptial Masses (outside clerics, servers, EMsHC, readers, etc. are very common – she’s not part of the loop unless someone asks her to be) I agreed to train him. I did so at a series of three Saturday morning Mass with the happy permission of the celebrant --a retired priest that had given me first communion decades before.
The training was complete and he was ready and waiting for the nuptial Mass when she heard about it. She went ballistic. It had nothing to do with doing the right thing, it had everything to do with a perceived threat to her turf.
She sent me 4 emails harsh, threatening emails telling me to tell the guy I trained to stand down. That she would assign a server for the coming nuptial Mass. In very careful terms I essentially told her to mind her own business. Then she started to call me with the same demands. My response was the same.
Then the vicar general (who I barely know) of the diocese called me – remember, we had no pastor at the time. She had started to email him! I very carefully explained what was going on and forwarded her emails to him. He then sent a brief email back telling me that it was taken care of, etc.
This the sort of thing that members of the parish had been exposed to.
