On the eve of the Reformation the relation of church and state shaped much of the history of Roman Catholicism, as it had done since the time of the emperor Constantine. In most of the states of Western Christendom, the 15th century was a time of awakening national consciousness, whose particularity and regionalism often set it in opposition to the universalism of a world church. In the Protestant Reformation of the 16th century, such opposition between nation and church led to a break with Roman Catholicism as such, but it is evident from the examples of 15th-century France and Spain that it could also lead to a national Catholicism that remained in communion with Rome. As the seat of the Avignon papacy and the stronghold of the conciliarism represented by Jean de Gerson, chancellor of the University of Paris, and Pierre Cardinal d’Ailly, 15th-century France represented just such a definition of Catholicism; and in the Pragmatic Sanction of Bourges of July 7, 1438, the French clergy came out in support of what were taken to be the historical rights of the Gallican church to administer its own affairs independently of Rome while maintaining its ties of filial loyalty and doctrinal obedience to the Holy See.
A few decades later, in 1469, the marriage of Ferdinand of Aragon and Isabella of Castile effected the union of Catholic Spain. In 1482 Ferdinand and Isabella concluded a concordat with the Holy See, under whose terms the Spanish crown retained the right to nominate candidates for the episcopate. Queen Isabella’s confessor, the humanist educator, Roman Catholic primate of Spain, and grand inquisitor Francisco Jiménez de Cisneros, blended Spanish patriotism, Renaissance scholarship, and a strictly orthodox Roman Catholicism in a form that was to characterize the church in the Hispanic lands of both the Old and the New World for centuries to come.
Spain was not the only nation-state with which the papacy had to contend. In 1516, after the French king Francis I defeated the allies of Pope Leo X (reigned 1513–21), the pope signed a concordat granting the king the right to nominate French bishops and higher church dignitaries, thus ending the election of bishops by cathedral chapters and abbots by monastic chapters. The age of Reformation and Counter-Reformation
The most traumatic era in the entire history of Roman Catholicism, some have argued, was the period from the middle of the 14th century to the middle of the 16th. This was the time when Protestantism, through its definitive break with Roman Catholicism, arose to take its place on the Christian map. It was also the period during which the Roman Catholic Church, as an entity distinct from other “branches” of Christendom, even of Western Christendom, came into being.
The spectre of many national churches supplanting a unitary Catholic church became a grim reality during the age of the Reformation. What neither heresy nor schism had been able to do before—divide Western Christendom permanently and irreversibly—was done by a movement that confessed a loyalty to the orthodox creeds of Christendom and professed an abhorrence for schism. By the time the Reformation was over, a number of new Christian churches had emerged and the Roman Catholic Church had come to define its place in the new order. Roman Catholicism and the Protestant Reformation
Whatever its nonreligious causes may have been, the Protestant Reformation arose within Roman Catholicism; there both its positive accomplishments and its negative effects had their roots. The standing of the church within the political order and the class structure of western Europe was irrevocably altered in the course of the later Middle Ages. Although Boniface VIII’s extravagant claims for the political authority of the church and the papacy were undermined by the Babylonian Captivity and the subsequent schism, by the mid-15th century the papacy had recovered and triumphed over the conciliar movement. By the time Protestantism arose to challenge the spiritual authority of Rome, however, the papacy had squandered some of its recovered prestige in its attempts to establish its preeminence in Italian politics. Indeed, the popes were so involved in Italian cultural and political affairs that they had little appreciation of the seriousness of the Protestant movement. The medieval political structure too had undergone change, and nationalism had become a more important force; it is not a coincidence that the Reformation first appeared in Germany, where animosity toward Rome had long existed and memories of the papal-imperial conflict lingered.
Accompanying these sociopolitical forces in the crisis of late medieval Roman Catholicism were spiritual and theological factors that also helped to bring about the Protestant Reformation. By the end of the 15th century there was a widely held impression that the papacy refused to reform itself, despite the relative success of the Fifth Lateran Council (1512–17), which was called by Pope Julius II. The papacy’s reputation had been damaged by the political and military machinations of popes such as Julius, and the hierarchy’s greed and corruption were demonstrated by Pope Leo X’s agreement (1514) to allow the sale of indulgences in the diocese of Mainz. The church also was plagued by the perception that professional theologians were more interested in scholastic debates than in the practical matters of everyday Christian belief and practice.
Despite, or because of, the rampant abuses of the hierarchy, there were efforts to reform the church. The most notable reformers were the Christian humanists, including Erasmus and Thomas More, who advocated an evangelical piety and rejected many of the medieval superstitions that had crept into church teaching. In Spain, Cardinal Jiménez undertook the reform of the clergy, restoring the observance of celibacy and other clerical and monastic rules of behaviour. Although condemned for heresy, Girolamo Savonarola represented the ascetic reformist piety that existed in the late 15th century.
During the Protestant Reformation the church’s conflicting tendencies toward both corruption and reform coincided with the highly personal struggle of Martin Luther, who asked an essentially medieval question: “How do I obtain a God who is merciful to me?” Luther at first attempted a medieval answer to this question by becoming a monk and by subjecting himself to fasting and discipline—but to no avail. The answer that he eventually found, the conviction that God is merciful not because of anything that the sinner can do but because of a freely given grace that is received by faith alone (the doctrine of justification by faith), was not utterly without precedent in the Roman Catholic theological tradition, but, in the form in which Luther stated it, there appeared to be a fundamental threat to Catholic teaching and sacramental life. And in his treatise The Babylonian Captivity of the Church, issued in 1520, Luther denounced the entire system of medieval Christendom as an unwarranted human invention foisted on the church.
Luther’s unsparing attacks upon the moral, financial, and administrative abuses of the church were initially prompted by the sale of indulgences in Germany by the Dominican friar Johann Tetzel. Luther insisted throughout his life, however, that the primary object of his critique was not the life but the doctrine of the church—not the corruption of the ecclesiastical structure but the distortion of the gospel. The late medieval mass was “a dragon’s tail,” not because it was liturgically unsound but because the medieval definition of the mass as a sacrifice offered by the church to God jeopardized the uniqueness of the unrepeatable sacrifice of Christ on Calvary. The cult of the Virgin Mary and of the saints, in Luther’s view, diminished the office of Christ as the sole mediator between God and the human race. Thus, the pope was the Antichrist because he represented and enforced a substitute religion in which the true church, the bride of Christ, had been replaced by—and identified with—an external juridical institution that laid claim to the obedience due to God himself. When, after repeated warnings, Luther refused such obedience, he was excommunicated by Pope Leo X in 1521.
