Unseen Warfare is one of the most enduring works of Orthodox Christian spirituality, a manual of inner struggle that has guided generations of believers toward spiritual sobriety and union with God.

Originally written in the late sixteenth century by the Italian priest Lorenzo Scupoli, the book was later translated into Greek and adapted for Orthodox readers by Saint Nicodemus of the Holy Mountain, who shaped it according to the teachings of the Philokalia. In the nineteenth century, Saint Theophan the Recluse translated and revised Saint Nicodemus’s version into Russian, bringing its wisdom to Orthodox readers in his own time. This English edition is based on Saint Theophan’s final Orthodox text, faithfully rendered for today’s readers.

At its heart, Unseen Warfare unveils the invisible combat that every Christian must wage within the soul—the struggle against pride, self-deception, and the subtle movements of the passions. Saint Theophan guides readers through the disciplines of vigilance, prayer, and discernment, revealing how to recognize the enemy’s tactics and how to depend wholly on the grace of God in the pursuit of holiness.

This edition offers:

- A clear, faithful English translation of Saint Theophan’s Orthodox version
- A systematic path of the spiritual life, from conversion to advanced prayer
- Practical counsel for maintaining watchfulness - and humility in daily life
- The distilled wisdom of three spiritual masters across centuries of Christian tradition

Whether you are new to Orthodox spirituality or long experienced in the life of prayer, Unseen Warfare offers timeless guidance for the most important struggle of all—the unseen battle for your eternal soul.
