For fifteen years he served as the executive director of the Center, an ecumenical organization whose mission is to cultivate faithfulness to the gospel of Jesus Christ throughout the churches, and also as the editor-in-chief of Pro Ecclesia, a journal of theology published by the Center. Braaten has authored and edited over fifty theological books, including Principles of Lutheran Theology (Fortress, 1983), The Future of God: The Revolutionary Dynamics of Hope (Harper & Row, 1969), Mother Church: Ecclesiology and Ecumenism (Fortress, 1998), Because of Christ: Memoirs of a Lutheran Theologian (Eerdmans, 2010), and Who Is Jesus?

He grew up on the island of Madagascar where his parents served as missionaries of the Norwegian Lutheran Church in America. He graduated from Augustana Academy, a Lutheran high school in Canton, South Dakota. He received degrees from St. Olaf College (BA), Luther Seminary (MDiv), and Harvard University Divinity School (ThD). In 1951 he was a Fulbright scholar at the University of Paris (Sorbonne), in 1957 a doctoral student at the University of Heidelberg where he wrote his dissertation, and in 1967 a Guggenheim Fellow at Oxford University. In 1974 he spent a sabbatical making a worldwide lecture tour of various colleges and seminaries in Japan, China, India, Kenya, Tanzania, Madagascar, Peru, Chile, Argentina, Brazil, and Mexico.
