This article uses a case study of InterVarsity Christian Fellowship to explore the social engagement of campus evangelicals. It focuses on InterVarsity’s massive Urbana student missions conference, a gathering that drew 23,000 young evangelicals to St. Louis in 2006. Drawing on ethnographic field observations, it profiles a campus group on the center-left of evangelicalism. Although InterVarsity promotes some conservative positions, it is increasingly progressive on issues of poverty, the environment, and race.
