Dudley M. Canright was born on September 22, 1840 and died on May 12, 1919. When he was 19 years old he joined the Seventh-day Adventist organization after working as a farm hand for Adventist minister Roswell Cottrell and attending a camp meeting held by James White. Encouraged by White, Dudley became a minister and evangelist for the Adventists and rose to prominence among the General Conference leaders.
In 1867 he married Lucretia Cranson who had been orphaned and partially reared by Ellen G. White. Together they had two surviving children, but in 1879 Lucretia died of tuberculosis. Two years later Dudley remarried. He and his second wife, Lucy Hadden, had three surviving children.
For 20 years Dudley worked as a minister and evangelist for the Adventists and was a frequent writer for the official Adventist magazine Review and Herald (now the Adventist Review). He was also often called on to debate Christian ministers, defending the seventh-day Sabbath.
Canright gradually became unable to support the “autocratic” behavior of James and Ellen White. He grew to disbelieve Ellen White’s visions and realized that according to Scripture, the Ten Commandments were not binding upon the church. He believed the Adventists were putting the law above Christ, and in 1887, Canright and his wife Lucy left the Seventh-day Adventist organization. He pastored two Baptist churches after he left, first in the Otsego Baptist Church in Michigan, and then, in 1890, he became the Pastor Emeritus of the Berean Baptist Church in Grand Rapids, Michigan.
During these years Canright wrote Seventh-day Adventism Renounced, and two months after his death in May, 1919, his critique The Life of Mrs. E. G. White was published.
The Adventist organization invented a story that members still believe—that Canright repented of his “apostasy” from Adventism before his death and returned to the Adventist fold. In fact, he never "repented" nor returned. According to a close friend, E.S. Ballenger, who was with Canright days before he died, "He said he was so disgusted with the deceptions of Mrs. White, James White and other leaders that he wanted to wash his hands entirely clean of the whole system. He died very quietly and peacefully and never made any confession or expressed any regrets regarding his course after leaving the denomination."
