She was in her day starting to meet this and was fighting this. She had different issues she had to deal with and put forth different amounts of effort on what was pressing at the time. The last issues was a tie about things that were starting to grow out of the first world war, and the proper use of her writings. This was her last great battle. She fought this battle as she was old and frail. Sadly, this is a battle she lost.
Stephen Haskell was a very close friend of hers, so close that when they were both widowed that he proposed to her. Yet, they had one big, on going argument; how prophecy works. He had a much more fundamentalist view and insisted that Mrs. White's experience fit the view of the Fundamentalists. She held a much more liberal view of inspiration and what visions did and DID NOT do for her. Both were frustrated that they could not convince the other to their understanding, but remained close friends.
After she died, he continued the same argument with Willie, where Willie gave the same ideas as his mother, but Haskell was far less cordial to Willie than he was to Mrs. White.
I see the wisdom for her turning down his proposal (and finding another woman for him.) Marriage can change attitudes, especially with the role of men in the 1800s. Would he have remained cordial with their different views of inspiration? Could their differences on how inspiration worked ripped the church apart?
There were less friendly correspondence between the Whites and the pastors who's thought developed into what is called "Historic Adventism."
Among their followers (I did not find this in their writings directly) there were people saying that Mrs. White no longer believed that she was a prophet. No, she did not give up believing that she was a prophet, she just had a different view of what a prophet was than what they insisted a prophet should be.
Sadly, I'm not sure how "shocked" she would be since she really had to face these issues, but she would be greatly disappointed that she lost the battle.
