i refer to seventh day adventists as jehovah's witness-lite.
but my knowledge of the adventists is limited, that's only from knowledge of my psycho grandfather's widow who is one...and from third hand knowledge, women can hold prominent positions and i think they're a bit looser when it comes to holidays, not sure about the trinity, but she used to address her letters as 'may jehovah bless you', type stuff.
also, my wife's friend was in something, i think it was the church of christ, or very similar wording, where the member numbers were similar and the shunning seemed spot on as well as the shaming of sexuality. if someone knows what i'm talking about and has the correct name of the church...i'd be interested.
in COC, didn't franz discuss a church that published a magazine similar to the Watchtower and they had the same date as 1914, but when they realized they were wrong, they apologized to their members....that might have been his other book....
as you can see i'm going through the memory of my fried brain, so hopefully someone can make sense out of one of the above better than i can.
