Book Review of Jon Diefenthal’s New Book on H. Richard Niebuhr: Diefenthal is concerned primarily with Niebuhr’s descriptive and prescriptive discussions of how the church relates to non-Christian society. This collection of texts is impressive and allows Niebuhr’s voice to come through clearly and effectively on the topic of the church’s relationship with the world. See the book at The Paradox of Church and World (Fortress Press, 2015).
