Some don’t have the discernment to see the dangers of authority outside the Bible. Glad that you do!
I would never worship in an SDA church. But most of the SDA’s I have known don’t consider themselves to be any more subject to Ellen G. White than a Presbyterian would be to Calvin, or a Methodist would be to Wesley, or a Baptist would be to Spurgeon. In a candidate, if I am looking at the moral potential, I certainly would prefer a conscientious SDA to a strictly nominal mainliner. Now, as to whether Carson would be an effective president, I don’t think he would be and I would not want him to get the nomination. But this business of trying to scare people away from Carson with the SDA bugbear is just silly.
