Summary, is used from an anthropological perspective to analyse the mechanisms of interaction between women and men in a given cultural system, based on gender identity, performed against the horizon of Catholic religion in public activities where they demonstrate their faith. Gender relations are analysed as mechanisms for symbolic interaction in the construction of a specific community around San Judas Tadeo in the city of Lima, Peru. The institutionalised mechanism for interaction and building a devotional community is the Franco apostolado de los Kalleros de San Judas Tadeo, who have two female institutions inside them. Ethnography, as well as interviews and discussions with actors, describe and analyse the participation of women and men in institutionalised public devotion based on the historical interdependence that has been formed between socio-religious and laical groups in the Peruvian capital.
