The past and present suggest two distinct pictures of World Vision. The organization began in 1950 as an American evangelical missionary support organization. Today it is the world’s largest privately funded Christian humanitarian organization undertaking relief, community development, justice, and advocacy. The evangelical identity of World Vision evolved as a result of professionalization and internationalization in a period of increased global connections. The story of World Vision’s evolution illustrates the recent rapid growth of evangelical mission organizations and their newfound eagerness to engage social issues alongside evangelism. This transformation within evangelical missions also serves as a significant context through which American evangelicals have encountered the world. While scholars have examined American evangelicalism as an explicitly American phenomenon by primarily exploring politics, theology, or its adaptation to popular culture, they miss the effect of global dynamics on American evangelicals. World Vision’s transformation offers another lens in which to examine one branch of an evolving post-World War II evangelicalism. A certain kind of professional management and technical knowledge along with a new engagement with a global Christianity and with other international humanitarian and development agencies enabled World Vision eventually to expand beyond an American evangelical subculture and reframe its evangelical identity while also attempting to transcend more typical American conflicts such as divisions between “ecumenism and evangelicalism” or “evangelism and social action.”
