The research seeks to analyse the sometimes ambiguous and conflicting relationships between masculinity, aggression and religion of adolescents in conflict with the law related to the Comando Vermelho (CV) - from two detention facilities in Rio de Janeiro. The analysis will be based on discursive and bodily performances, values and agonistic images that suggest violence as a value that reinforces masculinity and also confronts the law, the state and coexists with faith. These elements are identified in situations experienced in the context of religious assistance that took place in the aforementioned units.
