"It's a very positive and aggressive statement of Adventist beliefs", according to George Knight. "This book played an important role in the history of the Adventist Church", according to Gerhard Pfandl. "Questions on Doctrine" generated a theological movement which backs the theology of Andreasen and opposes the teaching set forward in the book. These "historic Adventists" perceive "Questions on Doctrine" as representing a major departure from traditional Adventist teaching, and believe that its publication has been harmful to the church. Other Adventists feel that "Questions on Doctrine" represents a courageous and insightful restatement of Adventist theology, while acknowledging that the book is not free from fault. For instance, it is clear that the authors pushed the facts too far with regard to Adventism's historic understanding of the Trinity, and present data about the human nature of Christ in a way that presents a false impression.
