"A Treatise of Witchcraft" by Alexander Roberts is a historical account written in the early 17th century. The work addresses the realities and dangers of witchcraft, providing a detailed discourse on witchcraft practices and a specific case involving a witch named Mary Smith, who was executed for her deeds. The treatise is posted as a warning to Christians about the moral and spiritual dangers of engaging with witchcraft and sorcery. The opening of the text begins by establishing the context of a world threatened by hidden evil, particularly focusing on witchcraft as a manifestation of the devil's work. Alexander Roberts emphasizes the urgent need for Christians to recognize and understand this wicked art through a true account of Mary Smith, who verbally contracted with the devil and caused harm to others. The discussion extends to a broader theological reflection on the existence of witches, the influence of Satan, and the moral implications of these dark practices, setting a foreboding tone that recognizes the dangers to both societal and individual integrity.
