Dicastery for the Causes of Saints

In the Catholic Church, the Dicastery for the Causes of Saints, previously named the Congregation for the Causes of Saints (Latin: Congregatio de Causis Sanctorum), is the dicastery of the Roman Curia that oversees the complex process that leads to the canonization of saints, passing through the steps of a declaration of "heroic virtues" and beatification. After preparing a case, including the approval of miracles, the case is presented to the pope, who decides whether or not to proceed with beatification or canonization.
