First the Bible students represented an insulated layer. They were the faithful and discreet slave of Jehovah who were expected to guide the people in all matters of overall import. But eventually someone noticed that in the first century, the seven churches were not independent, but had a council to guide them in weightier matters. These council members were sometimes divided and even given to bickering on occasion; thus, though they received revelation on occasion, they weren't inspired in all things and they added consistency to the church.
But now that they've edged out everyone else and they have their Governing Body, what's the chance of going with a one-man rule?
