The Manichaean Body is a work that strives to take the Manichaean worldview seriously by reconsidering previous scholarship on Manichaean anthropology and ritual in light of the practitioners own words. Throwing away preconceived notions of world-denying gnosticism, Jason BeDuhn reveals a religion deeply involved in Roman-Hellenic physiology and medical science. A distinctive and possibly unique materialist soteriology (it raises some questions on the origin of St Augustine's doctrine of inherited original sin). A religion devoted to transforming the human body into an organon for the liberation of a godhead trapped in the world as particles of light. A theology focused not on the individual's own escape from matter through gnosis, but universal salvation through the ascetic production of a specific bodily subject.
BeDuhn questions the role hermeneutical scholarship, in its well-meaning attempts to 'make sense' of ritual, has underplayed emic interpretation and self-description in favour of etic analysis of communication, metaphor, or social organization. The analysis of a ritual as a communicative act cannot sufficiently answer "why this act and not another?" without placing it in a theological context where the act serves a soteriological or practical end. Scholarship has interred Manichaeism in pre-existing categories of gnosticism or syncretism reflective of our own concerns, rather than understand how the Manichaeans utilized such syncretic practices for a distinctive theological end.
