The Millerites predated the SDAs. We need to be objective and fair about the Seventh Day Adventists and Ellen G. White. All one can say is that there is a MIXTURE of truth and error in this denomination. The problem is that 1% error can undermine 99% truth. With God it has to be 100% truth.
Well then, the issue is what is the truth and where can it be found, it is in Gods Word. So what church follows what God says, most dont bother to follow the Ten Commandments because the Sabbath is there, others dont want to hold that God is coming to resurrect the saints and take us at the Second Coming to heaven because they've allowed error to creep in, and we can just go through all the denominations. The scripture is Gods truth to us and we must allow the Holy Spirit to guide us into its truth, not follow traditions of man.
So what do Adventist believe, well, the following list comes from Steve Wohlberg's (an SDA pastor and theologian) website.
His page entitled is "
