A first century GB is a contrived entity to justify the current GB's position. Remember, these are the same guys who hire worldly lawyers to defend themselves in pedophile cases. These are the same "brothers" of Jesus who refuse to show up in court, admit to a hierarchy like the RCC, and haven't been able to make ONE DAMN VIDEO about Jesus in over 100+ years. Not one...
The current nonsense is that there was a GB but they were not the "Slave" which is a "composite" theological construct that doesn't really exist as an individual. ( very convenient for court)
This begs the question: Was Rutherford the first individual to comprise the composite "Slave?" Were Jesus' hand selected disciples feeding the sheep without a license? How could Peter feed the sheep, yet not be the "Slave" providing food?? When we teach others from the Bible, are we feeding them? If so, are we overstepping our bounds as domestics?
Or is the GB of the WTBTS simply trying to secure position and power? Only they are Slave on every Wednesday when they meet in the magical board room?? Is it all bull shit??
