This chapter suggests that the papacy dealt with Protestantism in various ways. It condemned the forty-one propositions of Martin Luther and then waited for the Council of Trent to condemn others. It used the institutions of preventive press censorship and of various inquisitions to check heresy. It sought the support of Christian rulers to prevent its spread, sending nuncios and legates to the rulers of the Holy Roman Empire, France, England, Scotland, Sweden, Denmark, and Poland–Lithuania to urge them to suppress heresy and to secure their loyalty by negotiating agreements on Church appointments and shared revenues and by offering military aid, efforts that had mixed success, or failed. Religious orders such as the Jesuits and Capuchins were also enlisted in the struggle. Leading Protestant reformers came to see the papacy as the Antichrist or foreign usurper.
