I suggest again that you speak with your bishop or missionaries.
My personal understanding is that this is a living Church, and that the present day Prophet or Authorities may tell us things which then, might or might not be considered doctrine. So the way to know the doctrine is to read the texts, attend the conferences, and listen to what the Authorities teach.
Other than that, I don't know what to tell you.
Is there a particular doctrine you're interested in?
If you think I'm mistaken, perhaps you should speak with the missionaries?
