I would suggest that you still can write a letter to the offending parish and her priest, admonishing them for their insolence to authority.
The 4th Commandment comes to mind (honor your mother and father), here.
Run it by your priest and inquire of correct wording and citations...don’t ask for approval.
I’ve done such before.
They don’t like to be called out.
In my case(s), they never whined about my admonition to my pastor.
They kept on, keeping on.
At least my conscience was assuaged.
I see. Writing the offending parish priest... 👍
