William of St-Thierry


William of Saint-Thierry was a twelfth-century French Benedictine abbot of Saint-Thierry, theologian and mystic who became a Cistercian monk and writer.

Biography

William was born at Liège of a noble family between 1075 and 1080, and died at Signy-l'Abbaye in 1148. He probably studied at the cathedral school in Reims, though some have argued it was at Laon, prior to his profession as a Benedictine monk. He became a monk with his brother Simon at the monastery of St. Nicaise, also in Reims, sometime after 1111. From here both eventually became abbots of other Benedictine abbeys: Simon at the abbey of Saint-Nicolas-au-Bois, in the Diocese of Laon, and William at Saint-Thierry, on a hill overlooking Reims, in 1119.
In 1118 William met St. Bernard, abbot of the Cistercian monastery of Clairvaux, where they formed an intimate friendship that lasted for life. His greatest desire was to move to Clairvaux and profess as a Cistercian, but Bernard disapproved of the plan and imposed on him the responsibility of remaining in charge of the abbey at St. Thierry as a Benedictine. Their friendship, however, grew stronger while Bernard lay in the infirmary of Clairvaux convalescing after an illness in 1125.
William was instrumental in the first General Chapter meeting of the Benedictine abbots in the Diocese of Reims, in 1131, and it is possible that he hosted the chapter meeting at Saint-Thierry. After the second General Chapter of the Benedictines, held at Soissons in 1132, where many Cistercian reforms were adopted by the Benedictines, William submitted his Responsio abbatum to Cardinal Matthew — papal legate in the diocese and critic of the abbots' reforms — successfully defending their reformation efforts. On account of long infirmities and a lifelong desire for a life of contemplation, William resigned his abbacy in 1135 and entered the newly established Cistercian Signy Abbey, also in the diocese of Reims. He did not venture to retire to Clairvaux lest his friend Bernard refuse to accept his abdication. There he divided his free time between prayer, study, and writing. According to a contemporary, his death occurred in 1148, about the time of the council held at Reims under Pope Eugenius. The necrology of Signy dates it 8 September, a few years prior to his good friend Bernard's death in 1153.

Writings

William wrote throughout all of his abbatial career as a Benedictine and his final years as a Cistercian monk. His earliest works reflect a monk seeking God continually and investigating the various and best ways of furthering the soul's ascent to God in spiritual union, William's ultimate goal. When read chronologically, one can discern the development and evolution of William's thought.
Toward the end of his career, having written extensively on spiritual life and especially on the moral interpretation of the biblical Song of Songs, William came across the writings of Peter Abelard, whose Trinitarian theology and especially Christology William found to be in error and dangerous to Christian faith. He wrote his own work against Abelard and alerted others about these concerns, urging St. Bernard to act. As a result, Abelard was condemned by the Council of Sens in 1140 or 1141. William wrote against what he saw as errors in the writings of William of Conches concerning Trinitarian theology and also against Rupert of Deutz on sacramental theology.
Besides his letters to St. Bernard and others, William wrote several works, some of which he himself enumerates, though somewhat incorrectly. In total, there were twenty two works by William, all written in Latin between c. 1121 and 1148.
In approximate chronological order, these include:
Three of William's writings were widely read in the later Middle Ages. However, they were frequently attributed to Bernard of Clairvaux - a sign of their quality and also another reason for their continued popularity. Only in the early twentieth century did interest in William as a distinct writer begin to develop again and was his name correctly attached to all of his own writings.
William drew upon the existing and traditional monastic and theological authors of his day and significant authors of previous centuries, but not in a slavish way; rather he is creative and independent in his thought and exposition. His own commentaries show his remarkable insight while they also incorporate traditional authors such as Augustine of Hippo and Origen of Alexandria. Perhaps his most influential works are those dealing with the spiritual life of the contemplative monk. From his On Contemplating God to his Golden Epistle, one can see a progressive evolution of William's thought and a maturing of William's spiritual insight and experience, while also noticing an improved, more polished writing style and organization. Some scholars also argue that although William drew on texts and authors in the past, his creativity and usage of spiritual terminology was also influential on many other authors from the 12th century onward.
The Latin texts of most of William's writings are contained in J.-P. Migne's Patrologia Cursus Completus Series Latina volume 180, with other works also in volumes 184 and 185. All of his works are available in critical editions in the Corpus Christianorum Continuatio Medievalis series from Brepols in six volumes. The bulk of William’s writings are available in English translation from Cistercian Publications.
