Actually, this is not a Don Camillo story, but it could be. If it were, at the end Dom Camillo (or "Mr Pulaski") would brag of his cleverness to Christ Crucified and be royally slapped down.
What would have made the story morally palatable is if the parish council hired a detective to find out what was going on with Fr. Stan. Then they could have gone to him in person and presented him with the evidence and the ultimatum. Or, indeed, depending on the severity (personally I suspect he just up to no good with the wannabe priestess), they could have gone to the police.
Ah me. O tempora, o mores.
