John Climacus: The Ladder of Divine Ascent (The Classics of Western Spirituality)

The Ladder of Divine Ascent is an ascetical treatise on avoiding vice and practicing virtue so that at the end, salvation can be obtained. Written by Saint John Climacus initially for monastics, it has become one of the most highly influential and important works used by the Church as far as guiding the faithful to a God-centered life, second only to Holy Scripture.
