This paper examines the study of religion by connecting it with two core contemporary themes: Critical Post-humanism and the animal. Critical Post-humanism, which is distinct from technology-focused Transhumanism (Posthuman-ism), re-establishes the relationship with animals through four key features: a powerful critique of anthropocentrism , the deconstruction of the human-animal boundary , the demand for an ethical expansion toward new ethical forms , and its intersections with Human-Animal Studies (HAS). The paper analyzes how religious studies have been influenced by the Animal Turn, noting the potential for significant contributions to scholarship. However, it also points out the risk that religious studies may treat the animal merely as an ‘object of study’ and fail to overcome anthropocentric bias. To address this, the paper argues that religious studies must adopt the Critical Post-humanist perspective to critically re-evaluate its content and embrace the study of ‘entanglements’ involving humans and nonhuman entities. It must also actively engage in ethical practice toward the more-than-human world. Additionally, based on the ontological parity premise of critical post-humanism, the paper explores the possibility of the animal as a subject of religious experience and considers animal religion as an affective, embodied process.
