I also think this overlapping generation idea was something that allows them to keep appointing younger and younger people to the Governing Body.
Shall we consider the ages involved of these overlapping groups?
D. Splane used the example of F. Franz, who died in 1992, 78 years after 1914. A similarly aged anointed, ( or older as D.S mentioned in the video), would live into the 2070s.
Wt bases the overlapping generation idea on Ex. 1:6, mentioning "Joseph,---- and that whole generation", and he himself lived to 110 years old; but even that is not enough for wt, they have to add his overlapping generation to it. So wt has a group overlapping a 110 year old as the only scriptural bases for their current light. Not making light of this, but
wt has come up with a 200 year period of invisible 1914-19 rulers waiting for the over lappers to die and join them.
Younger people are not going to fix that. A fix that is unfixable.
wt generated one generous generation. ~ 200 years, scripturally.
