Ellen G White claimed that in a vision, she saw that, and I quote, "I saw that the holy Sabbath is, and will be, the separating wall between the true Israel of God and unbelievers; and that the Sabbath is the great question to unite the hearts of God's dear, waiting saints." (Ellen G. White, Early Writings, p. 33).An highly inaccurate post.
William Miller was the prophet that stated Jesus would return in October 1844.
William Miller was not actually giving a prophecy but only his analysis of Daniel and the 2,300 days.
Ellen White believed that the analysis of the 2,300 day analysis in Daniel was correct.
Ellen White was evicted from the Methodist church for being a Millerite in 1843.
That was not Ellen's prophecy but a different analysis of the text in Daniel that William Miller gave.
William Miller admitted he was wrong and was never seen again.
All Ellen White did was modify that analysis of the prophecy in Daniel, that William Miller got wrong.
As for the ten commandments they were already insitu in the Reformation, then in the Methodist church.
Ellen White was raised as a child under the law.
So it's not a big step to go from under the law to a literal reading of the fourth commandment.
Why is Ellen White called a prophet?
"The pope has changed the day of rest from the seventh to the first day. (Not true, by the way). He has thought to change the very commandment that was given to cause man to remember his Creator. He has thought to change the greatest commandment in the Decalogue and thus make himself equal with God, or even exalt himself above God (Ellen G. White, Early Writings, p. 65).
Jesus begs to differ. He said that the greatest commandment is the first, not the fourth, and the second commandment is like the first. He also said that all the Law and prophets hang on the first and second commandment. Lord Jesus said nothing about the sabbath.
Ellen G White and her followers dismiss vast numbers of Christian who sacrificed their lives for the sake of the gospel. She derides mighty men of God as sabbath breakers.
I could go one, but to be honest, I find EG White's writings to be detestable and insulting to believers. She and her cult introduce nothing of value to the church. They sow division and confusion. Reject them.
