What do Christians pay attention to in order to decide if a given piece of text or manuscript is divinely inspired?

[Epistemologically speaking](https://en.wikipedia.org/wiki/Epistemology) , when a Christian is faced with a given piece of text, manuscript, book, etc., how does he or she go about deciding whether the material at hand is divinely inspired or not? What features of the text itself, or about its origin, or about whatever might be relevant do Christians pay attention to in order to decide if the piece of text they have in front of them was divinely inspired? For example, let's say someone is handing out cards with quotes from the Book of Mormon, and I receive one. What should I do in order to decide if the quote I received is divinely inspired? I know this question sounds a bit opinion-based, so to mitigate this, I would rather favor answers that reference official recommendations by any Christian denomination, group or institution. I'm tagging the question with 'denomination-survey' for this reason.
