This chapter traces the conflicting history of the relationship between the popes and the Inquisitions from the early modern period onwards, with a prologue on the late Middle Ages. Its scope embraces the Roman Holy Office alongside the Spanish and Portuguese Inquisitions, with their offshoots in the colonies, since to suppose that these latter were institutions entirely dependent on the Iberian monarchies is over-simplistic. The Roman court and the Index are treated more extensively, especially since the Holy Office was considered the most eminent Congregation of the Curia. The text also seeks to determine the extent to which the Roman Inquisition impinged on the autonomy of the popes or the development of Catholic dogma and orthopraxy on a global scale. Lastly, it looks at the later evolution of the Holy Office up until its mutation into the Congregation for the Doctrine of the Faith in the twentieth century.

The chapter reviews the models – ideal and actual – of the ‘good bishop’ put forward at the beginning of the sixteenth century, models which inspired those conciliar fathers most inclined to reform. It also looks at the debate pursued throughout the three phases of the council over the source of episcopal authority, focusing on the disputes about the theological basis of the obligation of residence. Finally, it will analyse what was new about the regulations regarding the clergy and the reforming decrees issued above all in the last sessions of the assembly, when the discord between the Curia party and the reformers threatened to wreck the council altogether. Without actually embracing the episcopalian position, the council did at least restate the importance of the care of souls, which was the responsibility of the pastors of the diocese, but failed to curtail the scope for curial intervention, the secular authorities’ nomination rights or the privileges enjoyed by the male religious orders.
