You will also struggle to find an up to date, and explicit explanation of why the year 1914 is given as the start of the Time of the End, or Christ "sitting down on the Throne to rule" or whatever, it is simply, if spoken of at all, expressed as a given.
The most up to date "explanation" is just an obfuscation.
The G.B and Writing Committee obviously take note of when us 'Poztates tear their pronouncements to shreds, and proceed to hide what their true, very silly, stance on matters is.
As steve2 says, this does not mean they have changed their view at all, it is just to hide the true Craziness that their teachings are from the Public.
If they believed they had the truth they simply would not do that, that is how we know that those at the top are fully aware they are running a huge SCAM !!
