Seventh-day Adventists Answer Questions on Doctrine (generally known by the shortened title Questions on Doctrine, abbreviated QOD) is a book published by the Seventh-day Adventist Church in 1957 to help explain Adventism to conservative Protestants and Evangelicals. The book generated greater acceptance of the Adventist church within the evangelical community, where it had previously been widely regarded as a cult. However, it also proved to be one of the most controversial publications in Adventist history and the release of the book brought prolonged alienation and separation within Adventism and evangelicalism.
