I'm not sure which specific 'Father Johann's Christmas story' you are referring to. There could be many different stories involving a Father Johann during Christmas. Maybe it's a local or personal story. Without more context, it's hard to say exactly what it is.

Since we don't have much information about 'big mouth story', it might be a story that revolves around the idea of communication and the consequences of talking too much. It could be about how a person's big mouth affects their relationships, whether it's with friends, family, or in a work environment. For example, in the story, the character with a big mouth might lose friends because they can't keep secrets, or they might get in trouble at work for gossiping. It could also be a story that uses the concept of a 'big mouth' metaphorically, perhaps representing a loud or outspoken group or community within the story.
One moral could be to think before you speak. Just like in the story where the boy spread false rumors without thinking. If he had paused and considered the truthfulness of what he heard, a lot of trouble could have been avoided.
