What it is
Singlin was the official confessor of Port-Royal from 1648 and the successor of Saint-Cyran as the community's spiritual director; he directed both the Duchesse de Longueville (Anne Geneviève de Bourbon) and the Marquise de Sablé, among the most prominent Jansenist nobles of the Bourbon court. His Instructions chrétiennes — sermons prepared in collaboration with Arnauld and Sacy — were published in five volumes in 1671 and became a standard devotional resource for the Port-Royal milieu. The documented pastoral relationship between Singlin and the Duchesse de Longueville (a Bourbon princess who built her house at Port-Royal des Champs) constitutes a direct court link.
Why it still matters
Singlin's Instructions provide a model of affective, Christocentric preaching shaped by Augustinian theology; preachers and laypeople seeking to deepen engagement with the liturgical mysteries of the Christian year will find them a rich resource.

The Practice of the Presence of God
La Pratique de la présence de Dieu
A collection of four recorded conversations, sixteen letters, and a set of spiritual maxims compiled posthumously by Abbé Joseph de Beaufort and published in Paris in 1692, one year after the death of Brother Lawrence — a lay Carmelite brother who spent his life in the kitchen of the Discalced Carmelite monastery of Saint-Joseph-des-Carmes in Paris. Despite his utterly humble station, he attracted visits from clerics and laypeople across France, including Cardinal de Noailles, Archbishop of Paris, who personally conducted four interviews with him and later authorized the book's publication. The work's central teaching — that God can be met with equal fullness in any ordinary moment and task — circulated in elite Parisian and court-adjacent religious circles during the final decades of Louis XIV's reign. Its endorsement by the Archbishop of Paris placed it squarely within the approved devotional culture of the French Bourbon court.
Pensées de M. Pascal sur la religion et sur quelques autres sujets
Pascal's posthumously published fragmentary apology for the Christian faith, compiled and edited by the Solitaires of Port-Royal and personally sponsored by Artus Gouffier, Duc de Roannez, Pascal's closest aristocratic friend and Jansenist patron. The work grew directly out of Pascal's spiritual direction of the Roannez family: passages from his letters to Charlotte de Roannez (1656–1657) were woven into the 1670 Port-Royal edition. The Port-Royal editors transformed the unfinished apology into a book of moral and religious meditation, making it the central devotional-apologetic text of the Jansenist noble circle at Paris and Versailles. Pascal's vision of God as hidden (Deus absconditus) and of the human heart's radical incapacity without grace gave Jansenist aristocrats a vocabulary for rigorous interior examination.
True Devotion to the Blessed Virgin Mary (Traité de la vraie dévotion à la Sainte Vierge)
Traité de la vraie dévotion à la Sainte Vierge
Written by St. Louis-Marie Grignion de Montfort around 1712 during a period of retreat, this treatise lays out a path of 'total consecration' to Jesus Christ entirely through Mary — a form of holy dependence in which the soul places all its prayers, merits, and actions in Mary's hands for her to offer to Christ. The manuscript was hidden during the French Revolution, buried in a wooden trunk by the Missionaries of the Company of Mary at Saint-Laurent-sur-Sèvre, and was not rediscovered until April 22, 1842, by Fr. Rautureau; it was published the following year to immediate and lasting acclaim. Eight popes endorsed it, and Pope John Paul II — who read it clandestinely under Nazi occupation of Poland — adopted Montfort's phrase 'Totus Tuus' (Entirely Yours) as his episcopal and papal motto. After 1843, it spread rapidly across Catholic Europe including France, Spain, Germany, Italy, and Poland, becoming foundational to Marian confraternity life in aristocratic as well as popular piety.
