HOPING to provide a comprehensive history of the Seventh-Day Adventist Church according to the representation of "work" and "message" by their adepts, the establishment of the Church's symbolic representation, and the organizational practices guided by prophetess Ellen G. White, this essay deals with the emergence, in Millenarianism, of the Adventist movement - which would transform the initial sect into a bureaucratically structured church, with its "commissioning" symbolically legitimized by the "mission". The presence of Adventists in Brazil between the end of the Empire and the beginning of the First Republic sustains the same initial characteristics of the movement, although it also generates numerous sects.
