An Ascetic Treatise by Abba John, Abbot of the monks of Mount Sinai, sent by him to Abba John, Abbot of Raithu, at whose request it was written.

The Ladder of Divine Ascent by St. John Climacus is one of the most profoundly influential spiritual classics in Orthodox Christianity. Written in the 6th century at the request of John, Abbot of Raithu, this timeless ascetic treatise offers a clear roadmap for the soul’s journey toward union with God. It has guided generations of monastics and laypeople alike, and is traditionally read in monasteries during Great Lent as a mirror for strict spiritual self-examination and repentance.

The work is structurally inspired by the biblical vision of Jacob’s Ladder, presenting thirty distinct «steps» or rungs that correspond to the thirty years of the earthly life of Jesus Christ before His public ministry. St. John masterfully delineates the rigorous yet spiritually liberating process of overcoming sinful passions, acquiring foundational virtues, and purifying the heart. The holy ascent begins with a sincere renunciation of the world and culminates in the supreme, transfiguring virtues of faith, hope, and love.

Though originally composed for desert monks, The Ladder remains deeply relevant for every modern Christian striving for inner stillness (hesychia) and eternal salvation. Through its pages, St. John offers spiritual medicine, stern warnings, and deep encouragement, reminding the faithful that the difficult climb requires both relentless personal effort and the boundless grace of God. It is an indispensable guide for anyone seeking to deepen their life in Christ and walk the narrow path of ascetical struggle.
