Of the duties, offices, and jurisdictions of the pope, few responsibilities were as crucial and esteemed as charity. This chapter surveys papal concern for and response to charity (500–1800 CE). The initial direction, speed, and efficacy of papal charity depended largely on individual popes and the contexts in which they operated. Charity became more regular with early Church councils and with the personal efforts of certain popes, but these endeavors remained informal until the Gregorian Reform and the Lateran Councils of the high Middle Ages. By the later Middle Ages, centralized charitable care emerged under the charge of the papacy: popes approved the creation of hospitals, protected pilgrims and prostitutes, and made regular charitable donations in kind and in coins. These efforts continued during the Reformation and Counter-Reformation, despite significant changes for the Church. Papal concern for charity never waned: from its beginnings to the modern period, the papacy embodied the Christian tenant to love one’s neighbor.

Usage of the title “Vicar of Christ” and the extent of powers implied in it supposedly peaked with Innocent III (r. 1198–1216) and Boniface VIII (r. 1294–1303); the image of popes as monarchic hegemons suited the attempts of legal, political, and constitutional historians to portray the growth of royal power, bureaucracy, and “nations” in competition with other forms of identity. More recently, the medieval papacy has been characterized as responsive and dialogic. Popes’ multiple roles as leader of the universal Church, Bishop of Rome, and ruler of the Papal States meant continual dialogue between center (Rome) and periphery in terms of appeals and petitions presented to the papal curia. Papal opinion and legal rulings mattered precisely because they were sought by regional churches and by secular rulers, and popes relied heavily on the College of Cardinals, judges delegate, and papal legates to represent papal decision-making. While the papal claim to the vicariate of Christ was often challenged by secular powers, this typically occurred in instances where earthly powers sensed that the vicariate of Christ was being wielded to intervene in matters critical to a definition of overlapping and occasionally competing spheres of government.

This chapter presents the main themes that emerge from a survey of the scholarly work that has been undertaken on the history of papal involvement with music. Seven centuries of papal pronouncements on music in the liturgy show a remarkable consistency of concerns, which could be summed up in the word “decorum.” Liturgical music must serve the Word, it must be solemn, it must be serious, it must not be there simply to be enjoyed, and it must not remind the congregation of secular matters. Yet it is striking how limited and how ineffective most papal decrees were. While popes consistently claimed global authority over all sorts of religious matters, only two issued decrees on music addressed to the entire Church. Even the papacy’s greatest contribution to the history of music, the creation of the plainchant repertory, was for the popes a local matter.

The College of Cardinals is a key constituent organ within the papacy, its members being charged with electing the pope and with advising him. Cardinals were originally priests and deacons who assisted the pope in his liturgical and charitable duties around the city of Rome during the first millennium and also the Bishops of Rome’s neighboring “suburbicarian” dioceses. These three orders of clerics cohered into a single College during the Gregorian reform of the eleventh and twelfth centuries: their status and role in papal affairs has waxed and waned in the centuries since. Today the College is more diverse and representative of global Catholicism than at any point in the past. However, it is also a larger and a less cohesive body, whose members are less familiar with each other – or with the pope – than their predecessors were.

The cooperative relationship between pope and city is the subject of this chapter. First, this chapter examines the political maneuvers necessary to execute change in Rome’s built environment and traces the conflict over jurisdiction between civic and papal polities, particularly over matters of urban improvements, licensing, and taxation. The papacy has long been a catalyst for transformation in Rome’s complex and layered urban landscape. Second, this chapter considers the ideology of the cityscape and the tradition of pilgrimage, historically and in our global age. From Martin V’s return in 1420, the papacy aimed to establish Rome as the epicenter of Christendom through its temporal and spiritual authority. As Christendom expanded through exploration and missionary efforts, so too did its capital. Popes continued to influence public space during the tumultuous period after the Unification of Italy, when fierce political rivalry materialized in the spaces of the city.

In the late Roman empire, the papacy’s endorsement of marriage as a divine institution was already explicita. From the mid-fifth century, fundamental importance was attached to the signification by marriage of Christ’s union of the Church, a value shaping the social practice of marriage, underpinning the creation in Roman Catholicism of a marriage system unique in the history of literate societies, one which banned both polygamy and divorce. More flexible laws limited marriage within the “forbidden degrees” of relationship. The aim was to foster social cohesion. These rules could be changed, or dispensed with, in individual cases. Marriage was made by consent, and only from the Council of Trent was the presence of a priest required. Christianity in general and papal law in particular slowly transformed the relationship between slavery and marriage.

This chapter examines the relationship between medicine and the papacy in the Middle Ages. It considers the historiographical debate amongst historians regarding whether popes were primarily adversaries to or advocates of the study and evolution of medicine. Focusing on the Avignon popes and their courts, it suggests that these individuals and their spaces increasingly became cultural centres for the production, transmission, and consumption of medical ideas and practices throughout the course of the thirteenth and fourteenth centuries. With the rise of medicine as a profession – and the sociocultural value this process bestowed on its practice – a pope’s patronage of medical activities granted prestige both to his court and to his beneficiaries.

The papacy’s long-standing entanglements with the twin disciplines of astronomy and astrology can be summarized along three thematic strands. One revolves around the ecclesiastical calendar and the astronomical exigencies of the reckoning of Easter, whose historical ramifications range from late antique Easter controversies to the Gregorian reform of the calendar (1582) and the beginnings of the Vatican Observatory. Another is the more general role of popes as patrons of astronomical research as well as their more anomalous involvement in scientific censorship during the cosmological controversies of the early modern period, as exemplified by the trial against Galileo Galilei (1616/33). A third is the complex relationship between the Roman Curia and astrology, which includes episodes of patronage as much as instances of sharp anti-divinatory legislation, with the latter culminating in the trial against Orazio Morandi (1630).

When and how did the Schism between the Western Catholic and the Eastern Orthodox Churches take place? The West commonly associates it with an incident in 1054 CE. Of the many points of difference and dispute between East and West in 1054, only two remain current: the ultimate theological authority of either ecumenical councils or the papacy, and the West’s insertion of the filioque (“and the Son”) into the Niceno-Constantinopolitan Creed of 381 CE. This chapter discusses both the origin of the filioque and the subsequent rise of monarchic papal authority in the West. The insertion of the filioque is sometimes incorrectly attributed to the Third Council of Toledo (589 CE), but it was definitively added to the creed by the Carolingians at a council in Aachen in 809 CE in close association with Charlemagne’s claim to be the only legitimate Roman emperor, and that change in the creed prevailed despite opposition at the time by Pope Leo III.

European diplomacy changed significantly during the Ancien Régime. Sovereign powers made increasing use of different categories of ambassadors while grappling with religious division, international conflict, and emerging globalization. Papal diplomacy was itself hardly new, although it too evolved in these challenging circumstances. In various respects, the structures of papal diplomacy mirrored those of Europe’s dynastic states. Popes were nevertheless supposed to abide by certain ideological values as paternal figureheads, maintaining peace amongst warring Catholic powers while extending authority beyond Europe. This was problematic, as the papacy sought to square its own political interests with its moral duties. Given early modern Europe’s changing political landscape it is also unsurprising that the papacy’s supranational power was under increasing pressure. That was evident by the mid-eighteenth century, and the upheavals of the Revolutionary and Napoleonic period, although today it retains its traditional identity as a neutral diplomatic actor.

Regardless of the intellectual coherence of hierocratic theory and the pope’s formal status as head of the universal Catholic Church and lynchpin of its central administration, the practical reality of papal monarchy had to reconcile that curial centralism with the logistical impossibility of exercising and enforcing direct control over all of Catholic Europe. Configured by local variables and interests, the integration of regional churches and polities within the papal network rested insecurely on a delicate balance combining delegation of authority, administrative decentralization, and local acquiescence. Incomplete subjection left space for local agency to exploit the perceived benefits of papal authority and obstruct its unwelcome intrusions. Using England as a case study, this chapter considers various manifestation of those complex ties (the activities of papal emissaries, and responses to and exploitation of the legal, fiscal, and dispensatory claims and structures), emphasizing the bottom-up perspective on medieval papal monarchy.

Canon law has played a role in the life of the Church since its earliest days. For many centuries, it was largely customary and local. However, from the sixth century on, the Roman pontiff played an increasingly prominent role in shaping and applying this law in the West. This tendency to centralize authority in the hands of the Roman pontiff reached its culmination with the promulgation of the first Code of Canon Law in 1917. Cut off from the law’s roots in history and theology, this code derived its force from the will of the pontiff who enacted it. The Second Vatican Council, from 1962 to 1965, attempted to balance the role of the pope with that of the College of Bishops and to move toward decentralization of authority by enhancing the figure of the diocesan bishop and creating episcopal conferences. These conciliar efforts have been implemented, at least in part, in the revised Latin code of 1983 and the Code of Canons of the Eastern Churches of 1990. Nevertheless, subsequent legislating has come largely through the unilateral action of the Roman pontiff.

Papal ceremonial acted as a language through which the pope and clergy described Catholic identity, history, and moral ideals, establishing a liturgy and ceremonial practice that could be adapted to changing circumstances in Rome and beyond. Topography did not restrict papal ceremonial but enhanced it. Rather than seeing the pope as a prisoner of his ceremonial, as some stereotypes do, this chapter explores papal ceremonial as a language that articulated narratives of authority, responded to crises, and bridged gaps. From late antiquity through the twenty-first century, liturgy, politics, urban administration, and pilgrimage/tourism grew together in cities across the Christian world. As technology has eased communication and travel, the pope has sought more direct ways to speak to Catholics, yet the public maintains an interest in the papacy that grew out of fascination with its premodern ceremonial character.

The Cambridge History of the Papacy is organized to provide readers with a critical–historical survey of the structural development of the papacy as an institution and as an actor in Church history, and in world history. It is hard to imagine a sphere of human activity over the past two millennia that has not been influenced by, and influenced in turn by, papal action – be it in the domains of religious belief and practice; social, cultural, and political thought; art, science, medicine, ethics, diplomacy, and international relations. Four questions – each addressed throughout the three volumes of the present work – have framed that vision across vast chronological and geographical expanses: the pope’s centrality within the Catholic Church, the primacy of papal power as an instrument of governance, the papacy’s cultural influence in society and culture, and the implications of secularity for its place in the lives of believers and non-believers alike. Each question – and the search for answers – converges around the fundamental question of papal authority: its original claims; the ebbs and flows of its effective reach; and the numerous ways in which claims, and expressions of papal authority and supremacy, have been contested within the Catholic tradition, and from without.

This chapter examines the papacy’s positioning vis-à-vis colonization and decolonization, defined both as a political changeover from European to African governance and as a longer, subtler, and more complex process of rejecting European influence and authority in both the public and private spheres, including religion. It investigates Vatican approaches to Catholic missions in Africa during the colonial period, how successive popes navigated the political changes of decolonization, and how they sought to make Catholicism more hospitable to Africans. Finally, it underlines how Africans themselves, such as the prominent intellectual Alioune Diop, played a central role in instigating papal action to make the Church less Eurocentric and more welcoming to other peoples and cultures.
