From earliest times the True Prophets and Messengers of the Lord have had to work against a barrage of criticism and contempt heaped upon them by the ungodly or misinformed. Ellen Gould (Harmon) White was no exception. 

Often the very ones who would most uphold The Testimonies to others, would, when the rebuke fell across their own path, turn tables to become venomous adversaries of what they once advocated.

The prime example of this is found in the life of Dudley Marvin Canright, who was helped and treated almost as a son by the Whites, and later turned away and wrote and published the grossest lies and most scathing criticism of what he once advocated. What Happened to D. M. Canright? See a short Biography of this man here:
