This article aims to investigate the relationship between religious fundamentalism in Brazil and the Non-partisan School (NPS) program. We sought to investigate the historical weight of Catholicism on Brazilian culture and political institutions, the strength that evangelicals have acquired in recent decades in the country, as well as whether NPS is an expression of religious fundamentalism in the current political situation in Brazil. The path taken to reach the results was based on bibliographic research, in addition to critical discourse analysis based on the examination of official documents produced by proponents of the Program and the content collected through interviews with teachers who work in the public health network education in the state of Ceará. The research concludes that NPS can, in part, be explained as a political strategy by religious fundamentalists (catholic charismatic movement and evangelicals linked to prosperity theology) who have sought to exercise power over the field of education, seeking to establish worldviews and patterns of behavior that strain democracy.
