RR,
I've been reading Pastor Russell's writings, and I get the impression that the "high calling" was not strictly speaking a "heavenly calling" as JWs think of it today. The emphasis seemed to be that it was a call to a higher level of existence (the divine nature) more than it was to a "place" called "heaven."
Pastor Russell believed that Jesus had actually returned to the earth's vicinity, though invisibly, whereas Rutherford changed this to a symbolic presence where Jesus actually remains in heaven. So to Russell, the saints when resurrected would have to remain at the earth with Jesus until the Millennial work was finished, at which time they could then return with Jesus to the Father's house.
But it seems also that the Bible Students were not consistent in this, and at times spoke of the departed ones as though they were already in heaven.
Do you think I have understood correctly what the original Bible Student teachings were, or have I overlooked something?
