There are books written about dealing with toxic older people. One author’s name comes to mind… Gloria Davenport… *… Or people suffering from Toxic Personality Disorder. It’s a form of OCD. Obsessive-Compulsive Disorder. Could also be a mild form of autism - engaging in inappropriate speech. A focus on small tiny insignificant things while ignoring “the big picture” could also be a symptom of a form of schizophrenia.
Could also be the result of a twisted upbringing. Children who lacked something at critical developmental stages may grow up with the inability to socialize well. I’ve had people say that they believe their “strength” is in criticizing others… [even though they are so personally fragile that can’t personally handle criticism from others.]…
Sometimes, AN approach might be to suggest a “format” for criticism or an “alternative form” of criticism… [for example, writing down the criticism in detail and then not mailing it.] Suggest some alternate wording for them. Or, that’s ok to lighten up just a bit … or “did you know that criticism can cause damage to the person on the receiving end and that we have a special obligation NOT to correct everyone”. Or “could we pray over this and let the Holy Spirit reach that other person who needs correcting.”
This is a difficult issue, and as other posters have suggested, is unfortunately quite common. I’ve had priests in weaker moments comment about complainers who actually go all the way to the Pope over minor issues.
I’ve seen these folks totally “unrecognize” the damage that criticism can do… with the result that whole congregations and ministers have been wrecked. Other people pull away…
Some of these folks just don’t have “a life”. So they focus all their energy on their parish and their efforts to make things “perfect”.
Another approach could be to spend some extra time before Jesus-in-the Monstrance… and simply ask Him to deal with it (the situation) in some very charitable sort of way… or for Him to send the Holy Spirit to you to give you the words to deal with it charitably.
I’m blathering, but this is a common issue and a very annoying one.*
