If the Watchtower Society had integrity, they would come right out and say neither Russell nor Rutherford were legitimately approved by Jehovah.
Of course, that will not ever happen.
They need to come up with a "change" which explains a sensible reason why they continue to teach things FROM JEHOVAH which need "adjusting" other than giving that lame illustration of "light" growing brighter and brighter.
It is NOT a reason for Jehovah to disseminate WRONG teaching!
The WTS is an organization exactly like the Catholic church and just as historically prone to corruption.
LET THEM EXPLAIN THAT and they might get some credibility back.
Note: It ain't uh gonna happen.
