This dissertation examines one of the most significant theological shifts in the Rastafari movement: the transformation of the Rastafari deity, His Imperial Majesty Emperor Haile Selassie I, from Jah in the flesh to the spirit that dwells within the body of each Rasta. Although the belief that Rastas are participants in the divinity of Jah emerged early in Rastafari, it was not until Selassie’s death in 1975 that the theological assertion of Jah dwelling within their bodies as the spirit emerged. Despite the initial claim made by some of the early Rastas that their bodies are the dwelling place of Jah, the notion of Jah as indwelling the spirit remains undertheorized, thus leading to an inadequate view that Rastafari is tenuously an African-derived religion. The aim of this dissertation, therefore, is to make visible the notion of Jah as spirit by focusing on how Rastas conceptualize and ritualize the process of Jah becoming a part of their bodies. The dissertation proposes divine envesselment as a central theoretical and conceptual framework to understand the Rastafari belief that their deity Jah becomes a permanent part of their bodies, thereby imbuing them with divine power, authority, and identity to resist the oppressive state Babylon. By formulating a theory of divine envesselment to account for the indwelling of Jah within the body, this study highlights the social, cultural, and theological factors that enabled Rastas to deify Selassie, continue to proclaim him as God after his death, and distinguish themselves from the oppressive neocolonial state through their ritualization of Jah spirit and power. The study uses an African-centered epistemological approach to argue that the Rastafari belief that Jah dwells within them is not only an embrace of the spirit but an ethos rooted in the history of contestation and creative friction within the Afro-Caribbean religious field. Furthermore, an African-centered epistemology locates the process of divine envesselment (Jah becoming the spirit that dwells in flesh) within the social, material, intellectual, and symbolic world of African people on the continent and in the diaspora. The study asserts that the logic, structure, and nature of Rastafari as an African-derived religion with a conception of spirit become evident when examined through an African-centered epistemological lens. / Religion
