1. I've issued six CFRs on BC's claim that everything the Church publishes is doctrine.
2. BC cannot produce a statement from the Church to this effect. When pressed, however, he points to other texts that don't make this claim either.
3. When I bring up the contents of these other documents to demonstrate that they don't make the claim, BC doesn't respond.
All incorrect. The 2007 statement states exactly what the doctrine is; official publication (IRI is not mentioned anywhere as it relates to doctrine). What you're missing is the fact that the Church has not made a list of exceptions. However, disclaimers and context do exist, thus the only conclusion you can reach is that it's all doctrine unless otherwise specified.
Notice also that in order to teach the doctrine and to keep the doctrine pure (both titles to sections in Teaching, No Greater Call), the publications are also referenced, no exceptions given. This is the way the Church views it and it's also the way most members of the Church view, they only exceptions I've seen are some online. In addition, as I have already referrenced, all these publications are started to be the "voice of the Church".
There are only so many different ways to state it and so far it has proven impossible for detractors to come up with something different so I don't feel obligated to always remain in a discussion where they ignore the pertinent facts and where their agenda takes precedence over intellectual honesty.
