The Cistercian Order

A return to the "letter" of the Rule of Saint Benedict

In the eleventh century, Western Benedictine monasticism was dominated by the immense network of Cluny, whose liturgical grandeur, landed wealth and solemnity of worship had gradually drawn monks away from the manual labour and primitive simplicity willed by Saint Benedict. The Cluniac day was almost entirely absorbed by a disproportionately lengthened Divine Office; farm work had been delegated to serfs and tenant farmers.^[6][7]

Cîteaux's plan was, against this drift, to take the Rule at its word. Saint Benedict wanted his monks to live by the labour of their hands (Rule, ch. 48); the Cistercians therefore took up manual work again as an integral part of monastic life. Saint Benedict wanted poverty and measure; they did away with precious ornaments, long processions and seigneurial revenues. This was called observance ad litteram — "to the letter".^[8][9]

"None but the ignorant or men of bad faith are capable of denying the merited praises which the sons of St. Benedict have received for their agricultural labours throughout Europe, or that this part of the world owes to them a greater debt of gratitude than to any other colony no matter how important it may be." — Leopold Janauschek, Originum Cisterciensium, quoted in the Catholic Encyclopedia, art. "Cistercians"^[10]

The "White Monks"

To distinguish themselves from the black Benedictines — the Cluniac habit was dyed black — the Cistercians adopted an undyed russet, of off-white wool, white or grey, covered with a black scapular for work. Hence their popular nickname of the "White Monks", as opposed to the Cluniac "Black Monks".^[11][12] This detail of dress was not inverted coquetry: undyed wool was simply the poorest and cheapest. The habit proclaimed the programme.

Cistercian and not "merely Benedictine": the nuance

The Cistercians are sometimes presented as "merely reformed Benedictines". The formula is accurate in substance — they follow the same Rule as all Benedictines — but it conceals the institutional originality of the Order. Before Cîteaux, each Benedictine abbey was in principle autonomous: there was no "order" in the juridical sense, only families of abbeys (like Cluny) held together by the dependence of their priories on a single, all-powerful mother-house.

Cîteaux invented something else: a genuine constitutional order, made of juridically distinct abbeys united by a common charter, uniform legislation, an annual parliament and mutual oversight. It is this invention — the Charter of Charity — which makes the Cistercians, more than their habit or their observance, a novelty in the history of the Church.^[13][14]

Stephen Harding and the birth of a new law

The Carta caritatis — the Charter of Charity — was drafted by Saint Stephen Harding, third abbot of Cîteaux, and approved by Pope Callixtus II on 23 December 1119, during his stay at Saulieu.^[15][16] It exists in two states: the Carta caritatis prior (1119) and the Carta caritatis posterior, revised to incorporate later statutes and confirmed by Eugene III in 1152; this second version remains the constitution of the Order.^[17]

Its genius lies in a single idea: to unite without enslaving. Cluny had unified its network through subordination — all houses depended on a single abbot, the abbot of Cluny. Cîteaux rejected this model: each Cistercian abbey remains autonomous, with its own elected abbot, its own patrimony, its own economy. But all are bound by a bond of charity — hence the charter's name — which guarantees unity of observance without destroying the freedom of each.^[18][19]

The annual General Chapter

First pillar: the General Chapter. Every year, all the abbots of the Order gather at Cîteaux. Together they legislate, correct abuses, settle conflicts and, if need be, depose a failing abbot. It is a genuine monastic parliament, the first institution of regular representative government in the religious West — a model that would later inspire the general chapters of the Carthusians, the Dominicans and the Franciscans.^[20][21]

Regular visitation and the system of filiation

Second pillar: regular visitation. Each mother-house has the duty of visiting annually the abbeys it has founded (its "daughters"), to verify fidelity to the observance and correct deviations. This is the so-called system of filiation: an abbey that founds another remains responsible for it as a mother for her daughter.

Oversight is mutual and reaches to the very top: Cîteaux itself is subject to the annual visitation of the abbots of the first four daughter-houses (La Ferté, Pontigny, Clairvaux, Morimond), who may correct the abbot of Cîteaux himself. No power escapes fraternal oversight — a remarkable balance for the twelfth century.^[22][23]

A bond of charity, not of power

The Charter finally lays down a total uniformity of observance: the same liturgical usages, the same books, the same customary, so that "a monk entering any abbey of the Order finds himself there as if at home". But this uniformity springs from a free agreement, not from domination. The text explicitly refuses any financial exaction of one house upon another: the mother draws no material profit from her daughters.^[24] The Order is thus governed by charity and by common law, not by money or feudal hierarchy — which was, in the full feudal age, a true spiritual revolution.

Here is the structure of government that the Charter of Charity bequeathed to the West:

La Ferté, Pontigny, Clairvaux, Morimond

The arrival at Cîteaux, in 1112–1113, of Bernard of Clairvaux with some thirty companions gave the Order decisive momentum. Within a few years, Cîteaux sent out its first four daughters, which would become the heads of the great European lineages:^[25][26]

Clairvaux, under Bernard's impulse, became by itself the mother of more than 160 abbeys: the Clairvaux lineage accounted for nearly half the Order by the end of the Middle Ages.^[27]

The golden age (1134–1342)

The Catholic Encyclopedia distinguishes four periods in the history of the Order: Formation (1098–1134), the Golden Age (1134–1342), Decline (1342–1790) and Restoration (after 1790).^[28] The expansion of the golden age was lightning-fast:

• At Bernard's death in 1153, the Order already numbered some 350 abbeys, not counting granges and priories.^[29][30]
• By the end of the thirteenth century, there were about 500 houses.^[31]
• At its peak, in the fourteenth–fifteenth century, the Order reached nearly 700 to 750 houses of men, spread from Ireland to Poland and from Scandinavia to Sicily and Spain.^[32][33]

No other religious family had ever grown so fast. The secret of this expansion was not only spiritual: it lay in a perfectly tuned economic and human machine — the lay brothers and the granges.

Who are the lay brothers?

One of the great Cistercian inventions — taken over from the Carthusians and a few predecessors, but systematised by Cîteaux — is the institution of the lay brothers (conversi). The lay brother is a religious in the full sense, bound by vows, but one who takes no part in choir and the Latin Office: he devotes his life to manual labour, farming and craftsmanship, thus freeing the choir monks for liturgy and contemplation.^[34][35]

The Charter specifies that they are not "monks" in the strict sense, but that "they must be treated, during their life and after their death, exactly as the monks themselves".^[36] In the great abbeys, the lay brothers could be two to three times more numerous than the choir monks: there were sometimes 200 to 300 of them in a single house.^[37] They lived in a separate wing, followed an adapted timetable and a simplified cycle of prayers.

The Cistercian granges

The lay brothers were above all the men of the granges: those monastic farms, sometimes several days' walk from the abbey, where the cleared lands were worked. The Cistercian grange — a vast agricultural building, byre, tithe barn, workshops — became a model of rational farming, a distant ancestor of the great modern farm.^[38] Thanks to the lay brothers and the granges, the Cistercians were able to colonise untilled lands that no one worked: marshes, forests, moors, remote valleys.

Ora et labora rediscovered

By reintroducing manual labour, the Cistercians gave new life to the formula attributed to the Benedictine tradition: ora et labora, "pray and work". The Cistercian monk was not a lord surrounded by serfs: he worked the land with his own hands, at least symbolically, and above all he organised, supervised and perfected this work. This dignity restored to toil had considerable historical effects on the European economy.

Clearers, hydraulicians, ironmasters

Because they settled in "deserts" — damp, isolated valleys chosen for solitude — the Cistercians became the great hydraulic engineers of the Middle Ages. They diverted rivers, dug canals, drained marshes, and drove by water-power mills that crushed grain, bolted flour, fulled cloth and tanned leather.^[39]

They were also great ironmasters: from the mid-thirteenth to the seventeenth century, their forges ranked among the first producers of iron in Champagne, even reusing phosphate-rich slag as fertiliser. At Fontenay Abbey, the forge stands inside the monastic enclosure itself — a unique witness to this monastic metallurgy.^[40]

Wool, vines and the economy

The Order developed an organised commercial system: the sale of livestock and horses, and above all of wool. The Cistercian abbeys of England stood at the heart of the great medieval wool and cloth trade, for which "England was largely indebted for the beginnings of its commercial prosperity".^[41] In Burgundy, around Cîteaux, the monks carried out the first attested vineyard-zoning project in history — the ancestor of the idea of the climat of Burgundy wines now classified.^[42]

The Apology to William: against the "monsters" of the cloister

Cistercian aesthetics cannot be separated from Bernard's combat against the artistic luxury of Cluny. In his Apology to William of Saint-Thierry (c. 1124–1125), Bernard mocks with famous verve the grotesque sculptures that peopled the capitals of Cluniac cloisters:

"To what purpose are these unclean apes, these fierce lions, these monstrous centaurs, these half-men, these striped tigers, these fighting soldiers and these hunters sounding their horns here? […] Men prefer to read in marbles than in manuscripts, and to spend the whole day admiring these things rather than meditating the law of God." — Saint Bernard of Clairvaux, Apology to William of Saint-Thierry, ch. XII^[43]

For Bernard, ornament diverts the gaze from the essential and feeds curiosity at prayer's expense. Decoration was therefore banished from Cistercian architecture: no figured sculpture, no historiated stained glass, no lofty stone bell-towers, no gilding. Only the crucifix was allowed.^[44][45]

The Bernardine plan and Fontenay

From this austerity was born a style of its own, sober and powerful, sometimes called the "Bernardine plan": a cruciform church with a flat-ended choir, a nave vaulted with a pointed barrel vault, no monumental tower, bare light entering through colourless windows, proportions reckoned by simple musical ratios. The abbey of Fontenay (Côte-d'Or, founded by Bernard in 1118 and listed as a UNESCO World Heritage site) is its best-preserved witness: in its stone can be read the Order's entire spiritual programme.^[46][47]

Light, proportion, silence of stone

Paradoxically, this refusal of ornament produced one of the summits of Western art. By suppressing sculpted anecdote and colour, the Cistercians forced architecture to speak only through light, proportion and emptiness. Many art historians see in this purification the matrix that prepared the vertical surge of the Gothic: the Order "contributed powerfully to the development and spread of Romanesque and then Gothic architecture throughout Europe".^[48] Cistercian austerity is not a poverty of art, but an art of poverty.

Cîteaux, a "school of charity"

The heart of Cistercian spirituality lies in a single word: charity. The monastery is understood as a schola caritatis, a "school of charity", where one learns to love God and neighbour through common life, obedience, humility and lectio divina. The great novelty of the twelfth Cistercian century is an affective, experiential spirituality: no longer merely reasoning about God, but tasting His love, describing the inner experience of the soul seeking the Bridegroom.^[49] This dossier is developed on its own account in Cistercian spirituality.

The four evangelists of Cîteaux

The first generation of Cistercian authors has been nicknamed — in Dom Anselme Le Bail's phrase — the "four evangelists of Cîteaux":^[50]

• Bernard of Clairvaux (1090–1153), the "mellifluous doctor", master of the Sermons on the Song of Songs;
• William of Saint-Thierry († 1148), Bernard's friend, theologian of love and of the image of God in the soul;
• Aelred of Rievaulx (1110–1167), "doctor of charity and friendship", author of the Mirror of Charity and Spiritual Friendship;
• Guerric of Igny († 1157), whose fifty-four Liturgical Sermons unwearyingly meditate the "spiritual form of Christ" to be reproduced in oneself.^[51]

Together they gave the West a mysticism of love of unrivalled literary and spiritual quality, which would nourish the whole tradition down to Teresa of Avila and beyond.

Loving God without measure

The manifesto of this spirituality is Bernard's treatise On Loving God (De diligendo Deo, c. 1126), addressed to Cardinal Haimeric. Bernard answers the question "why and how must God be loved?" with a formula that became famous:

"The measure of loving God is to love Him without measure." — Saint Bernard of Clairvaux, On Loving God, ch. I^[52]

He then describes four degrees of love: loving oneself for oneself; loving God for oneself (for His benefits); loving God for God; and finally loving oneself only for God — a supreme degree reserved essentially for the blessed life.^[53] This pedagogy of love, which starts from man as he is to lead him to pure love, sums up the whole spirit of Cîteaux: an ascent of charity.

"My God and my help, I will love You with all my strength, not as much as You deserve, but certainly as much as I can." — Saint Bernard of Clairvaux, On Loving God^[54]

The nuns and the mysticism of Helfta

The Order very early had a women's branch: from about 1125, the abbey of Tart (near Cîteaux) gathered Cistercian nuns, and women's monasteries multiplied. It is in the Cistercian wake that there flowered, in the thirteenth century, the great mysticism of the monastery of Helfta (Saxony), with Saint Gertrude the Great and Saint Mechthild of Hackeborn: a spirituality of the Heart of Christ, of revelations and liturgy, which from afar prepares the devotion to the Sacred Heart.^[55]

The Black Death and the end of the lay brothers

The golden age ended in the mid-fourteenth century. The Black Death (1348 and the following years) decimated communities and brought down the lay-brother system: lay recruits grew scarce, and abbeys had to let or farm out their granges to hired peasants, losing the economic model that had made their strength.^[56] The choir monk gradually ceased to be surrounded by that army of working brothers.

The commendatory abbots

The gravest blow came from a juridical institution: the commendam. Kings and popes took to appointing at the head of abbeys commendatory abbots — often secular clerics, even laymen, strangers to monastic life — who drew the abbey's revenues without residing there or sharing its observance. The living communion of the Charter of Charity, founded on regular abbots visiting and correcting their daughters, was disorganised. Added to this were geographical dispersion (which made visitations impracticable) and quarrels of observance between more or less fervent houses, notably over abstinence.^[57]

The Protestant Reformation and the French Revolution

The Protestant Reformation of the sixteenth century swept away the abbeys of northern Germany, Scandinavia, England and part of central Europe. Finally, the French Revolution (1790) suppressed the religious orders in France and dispersed the monks of Cîteaux itself: the mother-house, sold as national property, ceased to exist as a monastery — see the martyrs of the French Revolution. The Order seemed doomed to extinction.^[58][59]

Rancé and La Trappe (1664)

Long before the Revolution, a movement of return to fervour had sprung from within. The most famous was that of the abbey of La Trappe (Normandy, diocese of Séez), reformed from 1664 by its abbot Armand-Jean Le Bouthillier de Rancé. Rancé, a former man of the world turned convert, restored there an observance of extreme austerity: near-perpetual silence, hard manual labour, severe fasts, constant meditation on death. From this reform was born the current known as the Strict Observance, whose monks were nicknamed the Trappists.^[60][61]

Dom Augustin de Lestrange and the exile

When the Revolution closed the French monasteries, a monk of La Trappe, Dom Augustin de Lestrange, saved the Strict Observance way of life by going into exile. In 1791, he led twenty-four religious to La Val-Sainte in Switzerland, from where the observance then radiated across Europe and as far as America. It is largely thanks to this exile that the Order survived the revolutionary storm.^[62]

1892: two orders, one same sap

In the nineteenth century, the various Strict Observance congregations regrouped. In 1892, Pope Leo XIII united the Trappists into an autonomous order, distinct from the branch that had kept a more moderate observance. Since then, the family of Cîteaux has numbered two orders:^[63][64]

The two orders remain fully Cistercian: they share the Rule of Saint Benedict, the heritage of the Charter of Charity, the memory of Bernard, and the same contemplative sap. They are not rivals but two branches of one tree.

Nine centuries after Cîteaux, the spirit of the "White Monks" lives on in hundreds of communities across the world. Today's orders gather several thousand monks and nuns:^[65]

• the Common Observance (O.Cist.) numbers some 1,600 monks and 800 nuns, spread across several dozen monasteries and congregations;
• the Strict Observance (O.C.S.O., Trappists) numbers about 1,500 monks and 1,400 nuns, in a hundred men's monasteries and several dozen women's monasteries (figures around 2023).^[66]

Many of these communities still live, faithfully, by the labour of their hands: Trappist cheeses, beers, chocolates, jams — humble heirs of the medieval granges. And the silence of the Cistercian abbeys, from Cîteaux to Sénanque, from Le Thoronet to Tamié, keeps telling the world what Bernard wrote nine centuries ago: that for the human heart there is but one measure of loving God — to love Him without measure.
