I just find it amusing that it starts with a fixed point in time at Jesus and as Christendom start introducing new concepts based on Greek philosophy etc and are changing the narrative around the words of Jesus to something else entirely, that the WT point their finger and describe it as the great apostasy caused by "oppressive wolves infiltrating the congregation.
But when the WT organisation moves from a fixed point (C.T. Russell) forward introducing strange new ideas via Franz and Rutherford, the WT describe it as "new light from God".
Personally I see a parallel and am always surprised that WT members cannot even when they are brave enough to explore their own history!
