Hey, Rod,
Yes, I think teachers need to think over how they present information, considering the audience, and try to be clear as possible, especially for difficult or controversial topics.
Ravi Zacharias, for example, recognizes that theology should be handled precisely, and is careful to define terms, especially when analyzing others beliefs.
These days, there is a need for pastors has to express clearly, comprehensively (and defensively, unfortunately) what it is they are trying to communicate. in the past, Pastors spoke freely, as to "family", because their people knew where they were coming from and were
empathetic listeners. Those days are gone, with fault-finders and HH lurking around like sharks, ready to chomp on a sound bite they don't like.
