7th Day Adventist Church, What is It, and is there Anything Interesting about it?

OK, I stand corrected on some things, and I did almost put "prophetess" in quotes along with "founding." I may have stated things as being common knowledge as I perceived it. Thanks for everyone's input. I probably deserved the hammering. BTW, I always thought the Adventists did have a creed, but I have become aware that many churches do not.
