We do not know we are in the End Times. The idea that we are is an Adventist doctrine, based on the Millerite movement, and the Great Disappointment of 1844. Our Lord said that no one, not even the angels in Heaven, knows when the End Times will be, so such a doctrine contradicts the words of our Lord, the Only Begotten Son and Word of God, who is God Incarnate.
I can’t speak for the SDA church; I simply believe Ellen White is not a valid prophet. This does not exclude the possibility of the SDA producing a valid prophet.
So firstly, while I am not a Cessationist, Scripture does not refute Cessationism, which is why many of the mainline Protestant churches are Cessationist. So once again, I find myself being told what Scriptures say, when that is merely an interpretation.
They are also riddled with historical errors, failed predictions (where is the law prohibiting worshipping on Saturday and mandating worship on Sunday?), and historical inaccuracies and, additionally, plagiarism. One can see obvious plagiarism in
this article from Andrew’s University of the writings Octavius Winslow, which the article attempts to excuse as “borrowing,” and Ellen White being the “Master of these works.” Actually, only today did I look into the accusations of plagiarism against Ellen White, but I was startled by the dramatic extent to which she actually plagiarized. When I previously read The Great Controversy, I noted the numerous historical errors, but assumed they were entirely her own, due to a lack of knowledge of ecclesiastical history, but now it seems to me they are in many cases just reiterations of inaccurate books about church history by a variety of authors and groups in the 19th century, for example, the Landmark Baptists.
That does not excuse them from their failed predictions, historical errors and plagiarism.
What question did I not answer?
