Philipp Adolf von Ehrenberg became Prince Bishop of Wurzburg in 1622 and held the position until his death in 1631, ruling a prince bishopric that combined spiritual and secular authority over the same territory. Under his rule the Wurzburg witch trials reached their most severe extent, becoming one of the largest witch persecutions in early modern Europe, conducted with the full civil and ecclesiastical power a prince bishop held over his own subjects.

A dedicated detention and interrogation building known as the Malefizhaus was constructed in Wurzburg during these years to process the volume of accusations the trials generated, a purpose built institution rather than an improvised use of existing civic space. Estimates most often cited for the years of Ehrenberg's rule put the number of executions at around nine hundred, a figure that included children as young as three and members of the clergy, extending the trials' reach well beyond the accused witches of popular imagination.

That a sitting prince bishop presided over a persecution of this scale using purpose built infrastructure marks the Wurzburg trials as a documented case of church and state authority combined in one office producing one of the deadliest witch hunts of the period, a scale historians have used ever since as a reference point for how far such a persecution could extend when unchecked by any competing authority.

Friedrich Spee, a Jesuit priest, served as a confessor to condemned prisoners in Wurzburg during the years the trials reached their peak under Philipp Adolf von Ehrenberg's rule, a role that placed him directly inside the persecution rather than as a later chronicler working from records alone. Spee's own account described walking prisoners he believed innocent to their executions, a documented personal experience rather than an abstract theological objection to witch trial procedure.

Spee drew on those years of direct exposure to write Cautio Criminalis, published in 1631, the same year Ehrenberg died, arguing against the use of torture to extract confessions and against the trial procedures themselves rather than against the underlying belief in witchcraft. Because Spee had worked from inside the Wurzburg process as a confessor rather than as an outside critic, his book carried an authority that purely theoretical objections to witch trials had lacked.

That one of the most influential early arguments against witch trial procedure came from a priest who had personally accompanied Wurzburg's condemned to their deaths under Ehrenberg's own rule marks Cautio Criminalis as a documented consequence of the same persecution it argued against, a critique produced from direct experience of the process rather than from distance.
