Bernard of Clairvaux

Bernard was born in 1090 at Fontaine-lès-Dijon, a fortified village on the edge of Dijon in the Duchy of Burgundy ^[1]. His father, Tescelin le Roux, was a knight in the service of the Duke of Burgundy, and his mother, Aleth of Montbard, came from a noble family of the region. Bernard was the third of seven children, six sons and a daughter, raised in a household that combined the martial culture of the Burgundian aristocracy with a serious devotional life ^[2].

As a boy he was sent to study with the canons of Saint-Vorles at Châtillon-sur-Seine, where he received a grounding in grammar, rhetoric, and Scripture. Contemporaries who knew him later recalled an intense, bookish youth with a gift for Latin and an unusual sensitivity to the Psalms ^[1]. The death of his mother, probably around 1107, marked him deeply. Aleth had hoped her son would enter the Church, and biographers from the twelfth century onward have connected her memory to the religious turn his life soon took ^[2].

For a young nobleman of his talents, the obvious careers were arms, a cathedral school, or a comfortable benefice. Bernard chose none of them. Around 1112 or 1113 he presented himself at the gates of Cîteaux, a poor and austere monastery south of Dijon founded in 1098 by monks seeking a stricter observance of the Rule of Saint Benedict ^[3]. He did not come alone. In an episode that became famous, he arrived with roughly thirty companions, including several of his own brothers and other kinsmen whom he had persuaded to abandon secular life with him ^[1].

Cîteaux in 1113 was a fragile experiment. Its abbot, the Englishman Stephen Harding, was struggling to attract recruits to a life of manual labor, silence, and radical simplicity. The arrival of Bernard's large and well-connected party changed the community's fortunes, and the young monk quickly showed both the physical severity and the personal magnetism that defined his career ^[3]. His early asceticism was so harsh that it permanently damaged his health; he suffered from digestive ailments for the rest of his life ^[2].

In 1115, only about three years after entering the cloister, Bernard was chosen to lead a new foundation. With twelve companions he traveled north into Champagne and settled in a wooded valley on land granted by Count Hugh of Troyes. The site, once known locally as a valley of wormwood, was renamed Clairvaux, the valley of light ^[1]. The first years were bitterly hard. The monks lived on coarse bread and boiled leaves while they cleared land and built in timber, and Bernard, still in his mid twenties, had to learn how to govern men older and less fervent than himself ^[3].

Clairvaux nonetheless grew at an astonishing pace. Recruits came from across France and beyond, drawn by Bernard's preaching and by the reputation of the white monks for authenticity in an age uneasy about monastic wealth. Under his abbacy Clairvaux founded daughter houses across Europe; by the time of his death the abbey stood at the head of a family of well over sixty monasteries, and the Cistercian order as a whole counted around 350 houses ^[4]. Who was Bernard of Clairvaux in the eyes of his contemporaries? By the 1120s he was already the most visible spokesman of the new monasticism, and his letters and treatises were circulating far beyond the cloister ^[2].

Any account of Bernard of Clairvaux achievements has to begin with the papal schism of 1130. When rival factions in Rome elected two popes, Innocent II and Anacletus II, Bernard threw his weight behind Innocent. He argued the case at the Council of Étampes, then spent years traveling through France, Germany, and Italy to win over kings, bishops, and cities. Louis VI of France, Henry I of England, and the German ruler Lothair III all came around to Innocent's cause, in large part through Bernard's advocacy, and the schism effectively ended with Anacletus's death in 1138 ^[1]. A monk with no formal office had steered the politics of Latin Christendom.

Bernard was equally forceful as a guardian of doctrine. In 1140, at the Council of Sens, he confronted Peter Abelard, the most celebrated dialectician of the age, whose application of logic to the Trinity and to redemption Bernard regarded as dangerous. Abelard's teachings were condemned, and the philosopher withdrew to Cluny, where he died two years later ^[5]. Bernard later pursued a similar campaign against Gilbert of Poitiers at the Council of Reims in 1148. Modern scholars debate the fairness of these prosecutions, but they fixed Bernard's reputation as the era's arbiter of orthodoxy ^[4].

His influence reached its peak after 1145, when a former monk of Clairvaux was elected pope as Eugenius III. For the new pope Bernard wrote De consideratione, a candid treatise on the duties and temptations of the papal office ^[2]. At Eugenius's request he also preached the Second Crusade. His sermon at Vézelay on 31 March 1146, delivered before King Louis VII of France and a vast crowd, set off a wave of crusading enthusiasm, and he went on to recruit Conrad III of Germany ^[6]. When crusaders in the Rhineland began attacking Jewish communities, Bernard traveled there in person and preached against the violence, insisting that Jews were not to be harmed, an intervention recorded gratefully by the Jewish chronicler Ephraim of Bonn ^[6].

Alongside this public career ran a body of writing that secured his lasting fame. His eighty six Sermons on the Song of Songs, composed over nearly two decades, read the biblical love poem as an account of the soul's union with God and became a foundational text of Western mysticism ^[5]. Treatises such as On Loving God and On Grace and Free Choice, together with more than five hundred surviving letters, display a Latin style so fluent and musical that later ages called him the Mellifluous Doctor, the doctor flowing with honey ^[4].

Bernard never separated his inner life from his public one. He lived as a monk under the full rigor of Cistercian observance even while corresponding with popes, sleeping little, eating sparingly, and returning to Clairvaux between journeys to resume the round of prayer and preaching to his community ^[2]. His chronic stomach illness, the legacy of early excesses in fasting, meant that a special seat had to be provided for him in choir, and periods of severe sickness recur throughout his biography ^[1].

Family ran through his whole religious project. All six of his brothers eventually became monks, most of them at Clairvaux, and his sister Humbeline entered a Benedictine convent. His father Tescelin ended his days in the abbey his son governed ^[2]. Among his closest friends was William of Saint-Thierry, a Benedictine abbot and theologian who began the Vita Prima, the first life of Bernard, while its subject was still alive ^[3].

Those who met him described a slight, frail figure whose force lay entirely in speech and presence. He could be tender in his letters of consolation and ferocious in controversy, sometimes within the same week. He also possessed a deep devotion to the Virgin Mary, and his sermons helped spread Marian piety across Europe, an association so strong that Dante later chose Bernard as the final guide in the Paradiso, presenting the pilgrim to Mary in the closing cantos of the Divine Comedy ^[5].

The collapse of the Second Crusade in 1148 was the great wound of Bernard's old age. The armies of Louis VII and Conrad III were destroyed in Asia Minor and the survivors failed disastrously before Damascus. Because Bernard had preached the expedition, much of the blame fell on him, and in De consideratione he wrestled publicly with the humiliation, attributing the failure to the sins of the crusaders while admitting the scandal it caused ^[6].

He did not retreat into silence. In 1145 he had traveled through the Languedoc preaching against the dissident movement associated with Henry of Lausanne, and in his final years he continued to pour out letters on Church appointments, monastic discipline, and doctrine ^[4]. He also completed his last major work, the Life of Saint Malachy, a biography of the Irish reforming archbishop Malachy of Armagh, his close friend, who had died in Bernard's arms at Clairvaux in 1148 ^[1].

In 1153, gravely ill, he was persuaded to make one final journey, mediating a violent dispute between the city of Metz and the Duke of Lorraine. He returned to Clairvaux exhausted and died there on 20 August 1153, aged about sixty three, and was buried before the abbey's high altar ^[1]. Pope Alexander III canonized him only twenty one years later, in 1174 ^[3].

Few medieval figures cast a longer shadow. In 1830 Pope Pius VIII declared Bernard a Doctor of the Church, formally recognizing the authority of his theological writing, and in 1953 Pius XII devoted the encyclical Doctor Mellifluus to his memory on the eighth centenary of his death ^[4]. His feast is kept on 20 August, and he is honored not only in the Catholic Church but also in Anglican and Lutheran calendars ^[3].

His intellectual legacy runs in several directions at once. The Sermons on the Song of Songs shaped the whole tradition of Christian mystical writing that followed, from the Victorines to the Rhineland mystics, and his emphasis on love as the path to knowledge of God offered a deliberate counterweight to the scholastic method he had fought in Abelard ^[5]. Reformers as unlikely as Martin Luther and John Calvin cited him with respect, valuing his teaching on grace and on the mercy of Christ ^[4]. Hymns long attributed to him or inspired by his writings, including the texts behind O Sacred Head Now Wounded, kept his voice in congregational use for centuries ^[5].

The institutional legacy is just as concrete. The Cistercian expansion he drove changed the economy and landscape of Europe, as the white monks drained marshes, bred sheep, and pioneered agricultural estates from Yorkshire to Portugal and Poland ^[3]. Clairvaux itself survived as an abbey until the French Revolution; its buildings later became a prison, and the site is now being converted for public visitation. For readers who come to a Bernard of Clairvaux biography today, the essential Bernard of Clairvaux facts are quickly stated: a Burgundian noble turned monk who never held high office, yet judged popes, rebuked kings, defined orthodoxy, and wrote some of the most enduring spiritual prose in the Latin language ^[1].
