One view is that a significant number of theological issues re Christianity are debated because they are debatable. So, this view says, a relevant text might admit of multiple plausible interpretations, or weighing different texts against each other can lead to different plausible conclusions, and so on.
Is there a term for a theological principle that if the New Testament texts appear to be unclear about something, therefore that point is not important for salvation?
Note: this isn't a question about whether the relevant texts in fact are unclear, whether multiple interpretations are equally valid, and so on. It's a question about whether there's a term for this sort of theological principle.
