The Overlapping Whisky Doctrine is as follows:
It all started with Russell's whiskey. After a time and times and half a time of imbibing this spirit, Pastor Russell appointed himself the spiritual guide of Jehovah's people and came up with the 1914 doctrine. And then he died.
As an overlapping peer to Pastor Russell, upon his death, Judge Rutherford became the new spiritual guide of Jehovah's people. After an entire generation of imbibing this spirit, Rutherford came up with the doctrine of 'Millions Now Living Will Never Die'. And then he died.
As an overlapping peer to Judge Rutherford, upon his death, Fredrick Franz became the new spiritual guide of Jehovah's people. Since he was mostly a tea totaller , the spirit ran wild with this one. Franz came up with the doctrine of Armageddon by 1975. And then he died.
And now in the year 2019 we are blessed with Governing Body 2.0, some of whom supposedly overlapped with Fredrick Franz. We now realize that the 'spirit' that motivates these spiritual guides is probably Macallan's single malt. They have come up with the doctrines of tight pants, spanx and making a science out of begging for money. And soon they too will die. Lord only knows what 'spirit' will motivate the overlapping Governing Body 3.0.
