This chapter seeks to explore, from the study of the Brazilian case, the theme of the growing political action of evangelicals through the prism of their positions and their strategy based on the tension of moral agendas and the defense of the reversal of social conquests and the curtailment of political minorities. The analysis is based on the discursive logic of the conflict between good and evil. To this end, we contend that the debate follows a logic of battles, according to which political disputes are articulated as a clash of morally distinct worldviews in which evangelicals represent the rescue and defense of historical values against an alleged agenda of destruction of traditional sociability. The analysis undertaken here employs descriptive statistics from national opinion polls to illustrate the socioeconomic profile, ideology, and voting intentions of evangelicals. Additionally, it examines a collection of legislation that demonstrates the activism of evangelicals in institutional spaces, particularly in relation to moral categories.
