In this book, Miller undertakes a bold experiment – to deepen the theological conversation between African Pentecostal Christianity and western evangelicals by employing a shared ‘ancestor’ from early Christianity as a neutral dialogue partner. Through the lens of that early understanding of demons, virtue, and suffering, the shared thoughtworlds and theologies of modern deliverance ministry and the prosperity gospel gain clarity. This a book that will be helpful to missionaries, ministers, and lay leaders who encounter these theologies in their ministries. Western Christians concerned about spiritual warfare or engaged in ministry with African migrant communities will find this book enlightening.
