Rufus Anderson (1796–1880) for decades was head of the oldest and largest American missionary society and since 1866 professor of missiology at Andover Theological Seminary, one of the first chairs of missiology in the world. The Encyclopedia of World Mission calls him “the most influential figure in American missions.” Rufus Anderson’s most important call was for the self-reliance of young churches. He coined the “three-self formula”: Churches should be self-propagating, self-sustaining and self-governing. This book gathers articles about Rufus Anderson from the 19th and 20th century and presents a selection of his major tracts and articles.
