However, he reversed his views after a series of interviews with various leaders of the Seventh-day Adventist Church, and on reading Adventist literature. Martin reported his initial findings to Barnhouse, and between 1955-56 a series of small conferences were held, with Barnhouse and Martin meeting Adventist leaders like T. E. Unruh and LeRoy Froom. Barnhouse and Martin then published some of their findings in a series of articles that appeared in "Eternity Magazine" between September and November 1956. The standpoint taken by Barnhouse and Martin was that Adventists were largely orthodox on central doctrines, but heterodox on lesser doctrines, and so could be classified as belonging in the Evangelical camp. Martin later expanded his position in his 1960 book-length treatment, "The Truth About Seventh-day Adventism". Martin's book carried an explanatory foreword by Barnhouse and a statement from H. W. Lowe who was the chairman of the Biblical Study and Research Group of the General Conference of Seventh-day Adventists. While Lowe did not agree with Martin's criticism of the church's distinctive doctrines he nonetheless commended the book for providing a "fair and accurate statement of Adventist teachings." A committee of Adventist leaders themselves wrote and published a companion book, "Seventh-day Adventists Answer Questions on Doctrine", in 1957. While many Adventists welcomed the overtures of Barnhouse and Martin, there were other Adventists who questioned the position taken by church leaders in the volume "Questions on Doctrine".
