3 Spiritual Classics Worth Rediscovering

Three great devotional classics. Apart from the Bible, no devotional book has been translated into more languages than The Imitation of Christ.

From Aleteia

By Daniel Esparza

Timeless wisdom from The Cloud, St. John of the Cross, and Thomas à Kempis

Some books arrive at just the right time and others wait patiently until we’re ready to read them. The great spiritual classics of Christianity often fall into the second category. Their language can feel distant at times, their worldview shaped by medieval or early modern thought — but to dismiss them for that would be like walking away from a stained-glass window because the glass is old.

Classics endure not because they are flawless, but because they speak to the human heart in every era.

When we return to works like The Cloud of Unknowing, Sayings of Light and Love, and The Imitation of Christ, we do so not to find easy answers but to encounter enduring truths.

These texts were born from very different contexts — 14th-century England, 16th-century Spain, and 15th-century Germany — but each continues to guide readers toward a deeper interior life and a more honest relationship with God.

The Cloud of Unknowing: Unlearning for union

Written by an anonymous English mystic in the 14th century, The Cloud of Unknowing urges the reader to let go of images, concepts, and even thoughts about God. “By love He may be gotten and holden,” the author writes, “but by thought never.” The book insists that God cannot be grasped by intellect alone; He must be approached in love and humility, through what the author calls a “cloud of forgetting” of everything that is not God.

Yes, the language is Middle English. Yes, the metaphors are thick. But at its core is a quiet insistence that letting go — of control, of ego, of certainties — is necessary for union with the Divine. In a noisy world of overexposure and constant analysis, this work offers the surprising freedom of spiritual unknowing.

Sayings of Light and Love: Sparse, sharp, and seering

St. John of the Cross, the Spanish Carmelite mystic and Doctor of the Church, is best known for The Dark Night of the Soul, but his Sayings of Light and Love offer a more condensed — and often more accessible — window into his mystical vision.

These are spiritual aphorisms, not essays. “To love is to labor to divest and deprive oneself for God of all that is not God.” Or: “He who flees prayer flees all that is good.” The lines are dense with meaning and sometimes unnerving in their sharpness. But they are always aimed at freedom: freedom from sin, from illusions, from what John would call “appetites” that obscure God’s presence.

This is not self-help. It’s soul-help. And it demands patience, because the fruit comes slowly.

The Imitation of Christ: A quiet revolution

Often misread as a manual for the overly scrupulous, Thomas à Kempis’ Imitation is one of the most widely read devotional books in Christian history. Behind its monastic severity is a deeply humane awareness of weakness, vanity, and distraction — and a profound desire for Jesus as the center of the human heart.

“The more a man withdraws himself from things which are perishable,” Thomas writes, “the more he draws nigh unto God.” It’s not about self-denial for its own sake. It’s about clearing space for the only One who truly satisfies.

Like the others, The Imitation bears the marks of its age. But like the Catechism reminds us, “God calls man to seek him, to know him, to love him with all his strength” (CCC 1) — and these authors, in their own ways, invite us to do just that, earnestly.
