Great job as always, Blondie. Though I can stomach skimming these articles, I don't notice half the stuff that you do. You've definitely taught me to look for uh, what we might call Jesus' "invisible presence"--that is, a largely absent Jesus--in these articles. He is mentioned in there, but he gets overlooked quite a lot.
But in particular, you brought to my attention their mention of "this magazine" as the "primary channel for dispensing spiritual light." If this is true, then the Bible MUST be either (1) another 'primary channel' though not mentioned as such in this case or (2) a secondary channel. Either one of those possibilities presents a clear implication, which is really quite explicit--The Watchtower possesses EQUAL or GREATER authority than THE BIBLE. Okay. Well at least I know what I'm working against, here.
But the setup for this change was brilliant--smoke & mirrors all the way. God must be running the show in our religion, 'cause he's doing so in heaven! Uh...yeah...
If we assume the most naive assumption on this change, it still only buys maybe 40 reasonable years, tops. And by that time, it would seem implausible unless there is some clarifying explanation, as OntheWayOut said, as to when the overlap begins. Requiring a complete departure from even a hint of Bible evidence. But the Israel-in-the-wilderness parallelism would work--could reboot "this generation" at 1954 or so. Close enough to that Sputnik thing they were thinking about. Could work--at least goes reasonably beyond the lifetime of the current GB.
All in all, nice thread--satisfying as always.
