 They were called "Edicts of Grace" because all of the self-incriminated who presented themselves within a "period of grace" (usually ranging from thirty to forty days) were offered the possibility of reconciliation with the Church without severe punishment.The promise of benevolence was effective, and many voluntarily presented themselves to the Inquisition and were often encouraged to denounce others who had also committed offenses, informants being the Inquisition's primary source of information.After about 1500, the Edicts of Grace were replaced by the "Edicts of Faith", which left out the grace period and instead encouraged the denunciation of those guilty.
