The present dissertation investigates, through the Narrative Analysis and the theoretical contribution offered by Interational Sociolinguistics, the vocational narratives of future priests who are still in the formative process in institutions known as Seminary. The data presented in this research were generated in qualitative interviews with seminarians residing in the same Seminary as the researcher, who is also a seminarian. The research also has an auto-ethnographic sensitivity, since the researcher is also an integral part of a Catholic Seminary and, therefore, an active member of the same community that served as a research field. The analysis, of a qualitative and interpretative nature, takes place in a micro-interactional perspective and from the theoretical framework of Narrative Analysis (LABOV and WALETSKY, 1968; LABOV, 1972; BRUNER, 1997; LINDE, among others). Yet, we use the notion of Total Institution (GOFFMAN, 1961; FOUCAULT, 2006) to understand questions about the context in which these narratives are produced. The results describe that these narratives are based on a system of coherence of their own, in which rhetorical movements of orientation and evaluation are articulated, among which we highlight successful or successful evaluations of vocational choice and the idea of that the divine call is eternal and therefore innate. Also, it is possible to perceive the complex narrative construction in which the notion of agency is sometimes attenuated by the narrator due to the constant presence of two agents: I and God. In addition, the data indicate that these micronarratives dialogue with great narratives (BRUNER, 1997; SHOSHANA, 2013) understood by us as canonical and institutionally diffused among the seminarians.
