The Watchtower has always tried to draw parallels or precedent from Bible record and apply these to themselves.
Russell is now been given the honored position of the 19th century "John the Baptist" who layed the theological groundwork for the Watchtower organization. The Faithful Slave / Governing Body acts as mankind's mediator to God.
They effectively erased Jesus from the 'chain-of-command'. Why not Russell as well...
