Bernard of Clairvaux
Cistercian abbot, mystic, and co-founder of the Knights Templar.
Bernard of Clairvaux (1090 – 20 August 1153), known as Saint Bernard, was an abbot, mystic, and a key figure in the Cistercian reform of the Benedictine order. He also helped found the Knights Templar. Shortly after becoming a monk at Cîteaux, he was tasked with establishing Clairvaux Abbey. At the Council of Troyes in 1128, he helped draft the rule for the Knights Templar. During the church schism following Pope Honorius II’s death in 1130, Bernard strongly backed Pope Innocent II, successfully arguing his case against the Antipope Anacletus II. He promoted crusades and, through a well-known sermon at Vézelay in 1146, persuaded many to join the unsuccessful Second Crusade. Bernard was born to Tescelin de Fontaine and Alèthe de Montbard, both from Burgundy’s highest nobility. He was the third of seven children, with six brothers. At nine, he studied literature and rhetoric at a school in Châtillon-sur-Seine run by the secular canons of Saint-Vorles. After his mother died, he considered becoming a priest. In 1098, Robert of Molesme founded Cîteaux Abbey to follow a strict interpretation of the Rule of St. Benedict, creating the Cistercian Order. Following his mother’s death, Bernard joined Cîteaux in 1113 along with thirty other young noblemen, many relatives. His example drew many others, including his father, into monastic life, and he is considered a patron of religious vocations. Cîteaux grew quickly. Three years after entering, Bernard led twelve monks to found a new house in the Vallée d’Absinthe, in the Diocese of Langres. He named it Clairvaux on 25 June 1115, and the two names became closely linked. William of Champeaux, Bishop of Châlons-sur-Marne, made Bernard abbot, and they developed a strong friendship. Clairvaux’s early days were harsh, and Bernard’s extreme fasting often made him ill. Still, many sought to join him, and Clairvaux soon founded new communities: Trois-Fontaines Abbey in 1118, Fontenay Abbey in 1119, and Foigny Abbey in 1121. Over sixty abbeys followed during Bernard’s lifetime, some transferred to the Cistercians. Bernard spent much time away as a preacher and diplomat for the pope, and he called himself the “chimera of his age.” He faced trials, including when the prior of Cluny convinced his cousin Robert of Châtillon to leave Clairvaux, prompting a long, emotional letter. His brother Gerard’s death devastated him and inspired a moving sermon. The Cluny Benedictines criticized the Cistercians, so Bernard defended his order in his *Apology*. Peter the Venerable of Cluny responded with admiration and friendship, and Cluny undertook reforms. Bernard was canonized just 21 years after his death by Pope Alexander III. In 1830, Pope Pius VIII declared him a Doctor of the Church. In 1953, Pope Pius XII’s encyclical *Doctor Mellifluus* called him “the last of the Fathers.” Bernard opposed the scholastics’ rational approach to God, instead preaching poetically and appealing to emotion and conversion. He is considered a master of Christian rhetoric, and his lyrics appear in the Cistercian Hymnal. He emphasized personal, experiential friendship with Christ. As a mariologist, Bernard was not original but effectively spread devotion to Mary, stressing her humility and central role in theology.

Lore & Background
Bernard was born to Tescelin de Fontaine, lord of Fontaine-lès-Dijon, and Alèthe de Montbard, both members of the highest nobility of Burgundy. He was the third of seven children. Aged nine, he was sent to a school at Châtillon-sur-Seine run by the secular canons of Saint-Vorles. After his mother died, Bernard decided to go to Cîteaux. In 1113, he and thirty other young noblemen of Burgundy, many of whom were his relatives, sought and gained admission to the new monastery. Three years after entering, Bernard was sent with a group of twelve monks to found a new house at Vallée d'Absinthe, which he named Clairvaux on 25 June 1115. He was made abbot by William of Champeaux, Bishop of Châlons-sur-Marne. The beginnings were austere, and Bernard often fell ill due to extreme fasting. Nonetheless, candidates flocked to him. Clairvaux soon started founding new communities: Trois-Fontaines Abbey in 1118, Fontenay Abbey in 1119, and Foigny Abbey in 1121. In Bernard's lifetime, more than sixty abbeys followed. When his brother Gerard died, Bernard was devastated, and his deep mourning inspired one of his most moving sermons. At the solicitation of William of St.-Thierry, Bernard defended the Cistercians with his Apology against criticism from the Cluny Benedictines.
Reader's Guide
Bernard of Clairvaux's significance lies in his multifaceted influence on medieval Christianity. As a co-founder of the Knights Templar, he traced the outlines of their Rule at the Council of Troyes in 1128, shaping an ideal of Christian nobility. During the schism of 1130, King Louis VI convened a national council at Étampes, and Bernard was chosen to judge between the rival popes, deciding in favor of Innocent II. He traveled to Italy, reconciling Pisa with Genoa and Milan with the pope. He persuaded William X, Duke of Aquitaine, to abandon the cause of Anacletus after a dramatic Mass at La Coudre. Bernard also convinced many to join the unsuccessful Second Crusade through a famous sermon at Vézelay in 1146. As a Doctor of the Church (declared in 1830), he emphasized personal, experiential friendship with Christ and devotion to Mary, whom he called an 'aquaeduct of grace.' His poetic, emotional preaching opposed the rational approach of scholastics, and his use of language remains a lasting legacy. Despite his austere personal life and frequent illness, he was described by Jean-Baptiste Chautard as 'the most contemplative and yet at the same time the most active man of his age.' He was canonized just 21 years after his death by Pope Alexander III.
