Retired professor of history and sociology who has spent 30 years studying especially the changes in the Seventh-day Adventist Church as a result of it becoming global, with a clear majority of its members from the Developing world. I visited 60 countries for interviews in the process. I here make available to non-sociologists the papers I have published and presented at academic meetings on Adventism and also comparing Adventism's growth and spread with that of two other groups born in the US in the same century--Mormons (Latter-day Saints) and Jehovah's Witnesses.
