This article is an exercise in comparative theology from a Buddhist perspective. Christian liberation theology and engaged Buddhism both seek to empower people by liberating them from causes of suffering that prevent them from realizing their deeper identity and fuller potential. Christian and Buddhist liberation theologies differ in what they identify as the main conditions of suffering, as well as in the epistemologies they use to disclose those suffering conditions and to address them. Through their differences, the author argues, each tradition points out an epistemological weakness in the other that would otherwise have remained unnoticed and, by exposing it, helps correct it.
