Does this imply that there is never a "truth"
Of course not!
Since the organization IS the truth, it's just a matter that imperfect people don't understand certain things. As new light is introduced, the meek R&F then realize how stupid they were for not understanding something much sooner. Typically, it's because they lack understanding and have not applied the information sufficiently in their lives. They need to study more in the publications to readjust their minds to the truth.
Did that make any sense?
