In 1644, Germaine Cousin’s body is found intact by parishioners in the church of Pibrac, close to Toulouse. Devotions and miracles start and last until the canonization in 1867. This long-term devotion is problematic. This piety for someone who is considered as saint happens in a paracanonical context, without a formal recognition and outside of papal orders about sanctity and cult of saints. However, this situation does not mean conservation of a magical religion or limits of Catholic reformation. On the contrary, the case of Germaine Cousin shows the impregnation of Tridentine standards in the area of sanctity and cult of saints. The parish clergy plays the role of an important intermediary, controlling devotions, supervising miracles and working to promote a future canonization.
