I think of Ellen White the same as I do Mother Teresa. Someone with a purpose. Trying to do Gods will. It is not for me to judge either one. I no longer attend SDA Church because of their focus on her. I have no conviction on her one way or the other. Jesus should be the focus of any Church or believer. No prophetess, priest, Pope or any object of adoration should be a distraction in the true worship of God.
Actually one shouldnt be an SDA because their doctrine allows abortion( in their eyes, in a limited sense) and their hospitals as a follow on to that doctrine, officially and openly perform abortions.Other than that current mainstream SDA has little against it, with a less than mainstream attachment to Ellen White.
