"War has been abolished in Christ" is a strong claim by theologian Stanley Hauerwas. Wars, however, continue to rage, and historic numbers of people are displaced globally. Despite critics' assessments that Hauerwas contributes to Christians disengaging, his work provides certain tools for the work of peacebuilding. In this work, Hauerwas's contribution to peacemaking as a part of his ecclesiology and broader theological/ethical work will be assessed. Hauerwas's peacemaking within his work stands within the context of ecclesiology and related themes of witness and Christology. The possibilities of his work on peacemaking to extend to peacebuilding practice and foreign policy formation are explored, and a critique is leveled regarding his engagement with racial justice. Additionally, certain practices of reading in theology and training in this language are extrapolated to engage the task of policy formation and analysis in contexts where religion is an active factor. This study concludes that Hauerwas's theological ethics of peacemaking makes a valuable contribution, but must be extended into specific practices.
