So, why do you think there is so much "change" in doctrine? About things like the "generation?" Why do you think there is a lack of acknowledgement about 1914 and the generation that saw it? Why do you think they talk so little about 1914 these days?
Three reasons:
- Lame attempt at remaining relevant by coming up with "new light" nonsense so people still feel like they are getting something unique that no one else does
- They got sued left and right over all kinds of things from copyright infringement to sexual abuse coverups
- The way society is today doesn't help their model. People read a lot less magazines and go online, and people are a lot more aware about them, and people are more rude so they have a harder time buying into going house to house preaching.
I guess there's a 4th reason, which is that they are still as full of shit as they have always been, and they want to keep that status.
