Breaking news at NCT, which claims that "[LDS] leadership is worried about a growing rift in the church where members are identifying themselves as either orthodox or unorthodox members." That's nice to know, except what exactly is an unorthodox Mormon and why are they a problem?
While it is generally considered bad form to put labels on people, we nevertheless do require some categories to talk about what goes on in the Church. But at least we understand what these categories mean. Active or less active is straightforward: either you go to meetings regularly or you don't. Either you hold a temple recommend or you don't. You can be BIC or a convert. You can be a Ute fan or a BYU fan. You may agree or disagree about the utility of these distinctions, but we all know what they are talking about. When we use them, we know what we are saying and so do our listeners.
But what is an orthodox or an unorthodox Mormon? These terms are not in general use in LDS discussions. Are these just new terms referring to conservative or liberal Mormons? Those are equally confusing terms, first because many LDS seem to think are political labels designating Mormon conservatives and Mormon liberals and second because even if you use them with reference to variation in religious belief or practice it is still not clear what they mean in the Mormon context. Do these terms refer to orthodox or unorthodox doctrinal beliefs? If so, how do you determine orthodoxy or unorthodoxy without creeds to define orthodoxy?
So you make the call: How should we define an orthodox Mormon? An unorthodox Mormon? My view is that if you went to church last Sunday, you're an orthodox Mormon.
