Description:
The power and knowledge are presented in terms of epistemological differences relations, demarcated the tensions between Pentecostals and groups heirs of Reformation. The rejection of the Pentecostal experience was based on rationalist assumptions that can be perceived since Foucault's concepts and that reveal the supposed hierarchy of knowledge questioned by the analytical perspective of decoloniality. This article studies discourses of Pentecostal movement, which the matrix of scientific frame was introduced to depreciate or to legitimize marginalized religious phenomena, such as Glossolalia. We argued that not only the classical epistemology was brought to religious field and its fight against subordinate groups, but these groups themselves incorporated, in their own way, the excluding structure of scientific knowledge.
