Few works to date have examined the historical production of Brazilian Protestantism. This paper characterizes, and attempts to fill, this gap. It reviews the historiography of Brazilian Protestantism (1950 to 1990), drawing on the theoretical work of Michel de Certeau (theory of re-signification and reception) and Michel Foucault (theory of power). Analyzing the site of this historiographic production is central to any understanding of the paths and directions that emerged. Our hypothesis is that this historiography, in the face of struggles for power, reproduced apologistic narratives shaped by of conflicting elite theological positions. An unanticipated side of this historiography emerges in the fixing of religious subjects by the invocation of their memories. This side reveals another history, with a distinct temporality and unique preoccupations, one that often disdains ecclesiastical disputes. This alternative history concerns itself with the daily necessities and difficulties of these religious subjects, revealing a day-to-day reality that is immersed in the plural and diffuse Brazilian religious field.
