The Ladder of Divine Ascent by St. John Climacus
Saint John Climacus, sixth century abbot of Sinai, compared the spiritual life to a ladder of thirty steps, and explained in detail the challenges presented by each of those steps. This spiritual classic has brought inspiration and edification to every generation since that time. Read every year during Great Lent in monastic refectories, this book has been treasured by both monastics and laymen.
This is a beautifully-bound hardcover edition, translated from the Greek by Fr. Lazarus (Moore) and published by Holy Transfiguration Monastery.
