Ernest Sandeen the historian explains some of the reasons for its popularity, The Scofield Reference Bible combined an attractive format of typography, paraphrasing, notes, and cross references with the theology of Darbyite dispensationalism. The book has thus been subtly but powerfully influential in spreading those views among hundreds of thousands who have regularly read that Bible and who often have been unaware of the distinction between the ancient text and the Scofield interpretation.
