I never that individuals wrote articles. Golden Age was before my time. I don't see how you can attribute them to the WT. If someone can't provide a more concrete answer, I would just state that it is hard to trace the policy of the WT through the Golden Age articles. Your revelation changed my mind concerning using such articles as WT policy.
There is nothing in the archives. When I stumble upon the archives, I find that past posters seemed to spend a lot of time researching JW history. Why not call James Penton, who wrote Aocalypse Delayed. When I had some questions concerning his book, Mouthy encouraged me to call. He was still alive about six months ago. He is a historian. In fact, his book might contain information from The Golden Age. Certainly, your chart shows a clear split in belief. It would be wrong to assert a WTBTS policy from such divergent views.
I'm wondering if the Golden Age was a sort of measuring device to decide which way to go. Understanding the process of the Witnesses often reveals more than the doctrines themselves. Thank you for pointing out your problem. I learned something from it. So at one time it was allowed to have varying views. The WT has become more uniform over time.
I am curious whether someone's understanding of science gives a clue as to their theocratic position. Your research shows how complex the Witnesses once were. My mom forged my father's signature so my brother and I could receive vaccines. I cried so hard when the Sabin polio vaccine was distrubuted to the community at the local elementary school. The entire neighborhood was there - minus my father. Everyone was so grateful that a vaccine was available. There was a big argument at home. I touched the edge of the cup accidentally. I feared I would infect my father. Worse yet, I was too afraid to ask anyone. I am almost certain this was long after the Witnesses dropped their anti-vaccination stance.
Let me just remind people that my generation grew up with people who were seriously affected. Iron lung machines were particularly scary. It is hard to see how Satan controls this evil world when polio and smallpox are just about eradicated.
There were all kinds of fraudulent, nutty medical devices at Bethel while my father was there. Something like an Orgone box but not an Orgone box. I don't know why they were so anti Western Medicine.
