What challenges did John Calvin face?

John Calvin faced several challenges, including opposition from both the Roman Catholic Church and other Protestant reformers who criticized his views. In Geneva, where he sought to establish a theocratic government, he encountered resistance from civic leaders and citizens who were wary of his strict moral regulations. Additionally, Calvin dealt with internal disputes within the Reformed movement, particularly concerning predestination and church governance. His excommunication and initial exile from Geneva also posed significant obstacles to his reform efforts.
