Great how the subtly imply in paragraph 4 that you are being "selfish" if your research interferes in the "unified Good news" and further imply that any independent research amounts to "foolish questionings." Then they go own to recommend studying a book that is now unavailable and out of print: "All Scripture in Inspired" Who knows how much longer the Insight books will still be relevant.
Notice to how they use a "straw man" argument in paragraph two - they use the extreme case of brothers publishing websites or holding conferences to try and de-legitimise what started out in paragraph 1 as just brothers "meeting together to discuss."
