This suggests that you haven't studied any of those that you are lumping in together, which makes me wonder why you're lumping them in together. Charles Russell claimed that prior to Jesus being born of Mary, he was Michael the archangel, a created being, which he then became again after his ascension. Charles had several false prophesies and his followers continue to change his translation of the Bible, the NWT, as contradictions with their teachings are found. JWs are not Christians. Joseph Smith claimed that Jesus was a literal spirit-child of the Father and his wife, as was Satan. When those good Mormons who get married in the Temple die, they too can become gods of their own worlds. They have their own Scriptures, the BoM, which is held higher than the Bible. Mormons are not Christians. As for Ellen White, I am not that familiar with her but she did have many heterodox beliefs, most, if not all, were given to her in visions and dreams. She seems to have been a bit of a loose canon and control freak. She was also a known plagiariser. There appear to be some that are almost entirely orthodox but others that are not. John Calvin most certainly is not to be lumped in with that kind of company. He is the only legitimate theologian of all of these. There is nothing unorthodox in his teachings.
