Religious faith began to assume a new coloration after 1000 and evolved along those lines in the 11th and 12th centuries. Whether in the countryside or in town, a new, more evangelical Christianity emerged that emphasized the human Jesus over the transcendent Lord. The Crusading impulse was kept alive in France by the desire to vindicate the true faith against Muslim infidels and Byzantine schismatics. More intense Christian faith was also reflected in hostility toward France’s Jewish communities. As early as 1010 Jews had suffered persecution and were forced to choose between conversion or exile. Anti-Jewish sentiment grew during the next two centuries and led to further offenses. Expelled from royal territories by Philip II Augustus in 1182, Jews were readmitted in 1198 but suffered further persecutions, including a formal condemnation of the Talmud under Louis IX. Philip IV (the Fair) renewed the policy of expulsion in 1306.

The church was not always in a position to satisfy the religious demands of the population, however. The regular clergy could no longer be relied upon to set standards of piety and penitence; their observance was either too relaxed or too severe to suit the new conditions brought on by a rising population and the growth of towns. The canonical movement of the later 12th century produced a secular clergy that could respond to the needs of the laity in ways that the traditional monastic orders could not. The Cistercian order, even though it continued to expand, was incapable of sustaining its ascetic impulse completely; its houses, as well as those of the older Benedictines, were often remote from the new population centres. Nor was the higher secular clergy much better situated to fulfill pastoral obligations. The bishop was by now remote from his flock, acting usually as diocesan supervisor, judge, or lord; his subordinates—the archdeacon and cathedral canons—likewise functioned primarily as administrators. Archbishops were required by the fourth Lateran Council (1215) to hold annual synods of provincial clergy, a ruling that—although imperfectly observed—probably contributed to some strengthening of discipline.

Failure to improve the standards of parish ministry or respond fully to changing social conditions left the door open for the spread of heretical sects. The critical reform was that of the parish ministry. When emphatic measures to improve the education and supervision of priests were adopted in the fourth Lateran Council, it was already too late in France. For most of the 12th century, the same evangelical impulses that led to the reforms of the orders of canons and monks also contributed to anticlericalism and doctrinal heresy, especially in the towns and villages of the east and south. There was a suspicion that sinning priests could not be trusted to mediate God’s grace effectively, and the virtue of poverty as an antidote to the worldly cupidity of a prospering society was attractive to many.

The merchant Valdes (Peter Waldo), who gave up his property and family in the 1170s, took it upon himself to preach in the vernacular to his fellow townsfolk of Lyon. Although he gained the pope’s approval for his lifestyle, Valdes did not receive the right to preach. Nonetheless, he and his followers—“the Poor” or “Poor Men”—continued to do so and were condemned by the church, which drove them to more extreme positions on doctrine and practice. Despite strong opposition from the church, the Waldensian movement spread to southern towns, and small groups of adherents were found in Europe through modern times.

Another heretical movement, that of the “Good Men,” or Cathars (Albigenses), posed an even stronger threat to religious orthodoxy. Flourishing in the hill towns and villages between Toulouse and Béziers, the Cathars were dualists. They taught, among other things, that the material world was created by the Devil, that Christ did not assume the flesh but only appeared to, and that the church and its sacraments were the Devil’s work. In stark contrast to the often ignorant and worldly Catholic clergy, the Cathar elite, the perfecti, lived rigorously ascetic lives.

For this challenge, the secular clergy of Languedoc were no match. To establish an effective counterministry of learned and respectable men, the pope deputed Cistercians to Languedoc; they were soon succeeded by St. Dominic, who spent a decade as mendicant preacher in Languedoc. In 1217, with his order of preachers recognized by the bishop of Toulouse and confirmed by the pope, Dominic set out with his fellow friars to work in the wider world “by word and example.”

Meanwhile, the murder of the legate Peter of Castelnau (1208) had stirred Innocent III to promote a Crusade against the heretics of Languedoc. Led by Simon de Montfort, northern barons attacked towns in the viscounty of Béziers and later in the county of Toulouse with singular fury. The Albigensian Crusade brought the south under northern subjection, as massacres and the establishment of a papal Inquisition (1233) eventually drove the Cathars into exile in Italy or back to Catholicism. The Inquisition, which spread to many parts of France, was usually entrusted to Dominicans; it relied on the active pursuit of suspects, secret testimony, and—in case of conviction and obstinacy—delivery of the heretic to the “secular arm” for capital punishment.

Like the Dominicans, the Franciscans had spectacular success in a variety of endeavours. Highly organized, with provincial and international administrative institutions, both orders had houses in Paris by 1220, and their members were soon working everywhere in France. Becoming preachers and confessors, they also secured chaplaincies, inspectorships, and professorships as their initiatives in piety, probity, and learning were recognized. Conflict with the secular priesthood naturally resulted; the seculars attempted unsuccessfully to exclude the mendicants from the ministry of sacraments and inveighed against conventual endowments that seemed to contradict the friars’ professions of poverty. Despite this conflict, the friars, women’s orders such as the Poor Clares, and similar groups such as the Beguines stimulated a more active piety among laypeople, encouraging charitable works and foundations, private devotions, and penitential reading.
