Heresy refers to beliefs or practices that deviate from established religious doctrines, particularly in Christianity. During the time of the Catholic Reformation, heresy became a central concern for the Catholic Church as it sought to reaffirm its authority and counteract the rise of Protestant movements. This led to the establishment of measures to identify, condemn, and suppress heretical ideas, reflecting broader themes of religious conformity and control during this tumultuous period.
