Based on our best data from the White Estate, Ellen White’s writings do not contain explicit statements of racism as understood today. She consistently advocated for the dignity and salvation of all people, regardless of race, and condemned prejudice and injustice. Concerns about Ellen White and racism often arise because she lived during the 19th century, a time of widespread racial prejudice. In some cases, she addressed the realities of her time using language or recommendations that can be misunderstood without historical context. For example, she sometimes advised caution regarding social and marital relations between races—not out of a belief in racial superiority, but due to the severe prejudice and danger present in society at that time. The official White Estate position is that Ellen White was not a racist and that her counsel should be understood within its historical context. References: - White, E. G. (Various).
