The Difference Between the Temporal and the Eternal
De la diferencia entre lo temporal y eterno
Lo temporal pasa como sombra: lo eterno permanece como Dios.
Our renderingThe temporal passes like a shadow; the eternal endures like God.
What it is
A landmark seventeenth-century Spanish Jesuit ascetical treatise by Juan Eusebio Nieremberg (1595–1658), a professor at the Colegio Imperial in Madrid who served under royal command as confessor to the Duchess of Mantua. Drawing on Ignatian imaginative contemplation, the book leads the reader through a vivid, affectively charged meditation on the radical difference between transient worldly goods and eternal realities, presenting the last things — death, judgment, heaven, and hell — as the truest corrective to disordered attachment. It became one of the best-selling Jesuit religious titles of the century, running through more than fifty Spanish editions and translated into multiple European languages. A specific claim of a first American printing in Paraguay in 1705 could not be independently verified and should be treated as unconfirmed.
Why it still matters
Its core method — sustained imaginative contemplation of eternity as a counterweight to worldly temptation — is a direct application of the Ignatian Two Standards meditation and can be practiced in any daily examination of conscience.

Introduction to the Devout Life
Introduction à la vie dévote
Composed initially as spiritual direction letters for Madame Louise de Charmoisy — wife of Claude de Charmoisy, ambassador of the Duke of Savoy — this work was explicitly written for lay people living 'in town, within families, or at court.' It received a royal privilege from Henri IV of France on 10 November 1608 and was first published at Lyon in 1609. Francis de Sales shaped each of its five parts around the practical rhythms of court and household life, treating topics from meditation and vocal prayer to temptation and worldly conversation. The Introduction circulated widely in the dévot circles of the French court and became the devotional manual par excellence for Catholic lay formation in the early modern period.
Spiritual Exercises
Exercitia Spiritualia
The Spiritual Exercises is a structured four-week program of meditations, prayers, and self-examination composed by Ignatius of Loyola and first printed with papal approval from Pope Paul III in 1548. The program moves through radical self-knowledge, the life of Christ, the Passion, and the Resurrection, aiming at a thoroughgoing reordering of the will toward God. Francis Borgia, Duke of Gandia and future Jesuit Superior General, made the Exercises after his wife's death in 1546 and subsequently vowed to enter the Society of Jesus; Princess Juana of Austria (1535–1573), daughter of Charles V, secretly made the Exercises in 1554 and was admitted as a Jesuit scholastic under a male pseudonym, with Francis Borgia organising her retreat. Jesuit directors of the Exercises served as confessors to virtually every major Catholic dynasty from c. 1575 onward, making this text the single most influential Catholic devotional manual in the post-Tridentine period.
Spiritual Exercises (Exercitia Spiritualia)
The foundational Jesuit method of prayer and discernment composed by the Spanish-Basque Ignatius of Loyola, structuring a four-week guided retreat through meditations on sin, the life of Christ, the Passion, and the Resurrection. Its Habsburg connection runs deep: Joanna of Austria (1535–1573), daughter of Charles V and sister of Philip II, was secretly admitted to the Society of Jesus under the alias 'Mateo Sánchez' after undertaking the Exercises under the direction of Francis Borgia, former Duke of Gandia and a close Habsburg courtier—making her the only woman ever enrolled in the Jesuit order. Philip II was unaware of his sister's membership, yet the Ignatian network shaped the spiritual climate of the court from within.
