This book develops a Pentecostal ecological theology (ecotheology) by utilizing key pneumatological themes that emerge from the Pentecostal tradition. It examines the salient Pentecostal and Charismatic voices that have stimulated ecotheology in the Pentecostal tradition and situates them within the broader context of Christian ecumenical ecotheologies (Roman Catholic, Orthodox, Protestant, and Ecofeminist).
