Epistolae (Selected Letters of Bernard of Clairvaux)
Epistolae Bernardi Clarevallensis
Scio enim quia plenum est cor tuum bona voluntate in Deum et servos eius, quod rarum in tam alta dignitate.
Our renderingFor I know that your heart is full of good will toward God and his servants, which is rare in one of such high dignity.
What it is
547 surviving letters from Bernard constitute the most important corpus of 12th-century spiritual direction addressed to rulers, nobles, and queens. The Epistolae project at Columbia University documents his letters to Adelaide of Leuven (Duchess of Lorraine, before 1139), Eleanor of Aquitaine, Ermengarde of Anjou (Countess of Brittany, c. 1130–32), and Melisende of Jerusalem, all confirmed by the Epistolae database. Bernard also preached the Second Crusade before King Louis VII of France at Vézelay in 1146 and maintained ongoing correspondence with the Capetian court. These letters functioned as private devotional and moral formation texts for their royal and noble recipients.
Why it still matters
The letters on spiritual direction to noblewomen — particularly Letters 113–116 in Bruno Scott James's edition — model a form of honest, demanding accompaniment that applies directly to modern Christian mentorship.

De consideratione (On Consideration)
De consideratione ad Eugenium papam
Five books of spiritual and pastoral counsel addressed personally to Pope Eugenius III, himself a Cistercian monk trained under Bernard, written between 1148 and 1152. It functions simultaneously as a mirror for the supreme ruler and as a manual of contemplative self-examination, warning against the tyranny of busyness and calling the highest officeholder back to inner recollection. A manuscript copy dated c. 1465 survives at the University of Chicago; the work was widely read by reform-minded clergy and rulers who circulated it as a model for Christian governance. Bernard addressed it directly to a head of state with whom he had a personal, documented formation relationship.
Epistolae: Letters to Frederick Barbarossa and Henry II of England
Epistolae
Hildegard's surviving correspondence (c. 390 letters) includes direct prophetic and spiritual admonition to Frederick Barbarossa from 1153 — warning him against misrule and schismatic papal appointments — and a separate letter to Henry II of England (dated 1154–1170) cautioning him not to follow personal will over justice. Frederick responded positively, inviting her to court for prophecies and later confirming their fulfilment. The Columbia Epistolae project and Oxford University Press three-volume edition (Baird and Ehrman) document these exchanges with full scholarly apparatus.
Orationes sive Meditationes (Prayers and Meditations)
Orationes sive Meditationes
A collection of nineteen prayers and three meditations composed by Anselm of Bec between c. 1070 and 1085, representing the founding documents of western affective devotion. Anselm sent a personalised copy to Princess Adelaide of Normandy (daughter of William the Conqueror) in 1081 in response to her request for psalms, adding long intimate prayers addressed to individual saints. He later sent a 'Matildan recension' of twenty-two prayers and meditations to Countess Matilda of Tuscany during his second exile (1103–6), composing at least one prayer (Oratio 1) expressly for her use. The prayers are cast in a new mode of intense psychological self-examination, designed to arouse compunction, love, and fear of God in private reading.
