John’s major works, The Ascent of Mount Carmel, The Dark Night of the Soul, The Spiritual Canticle and Living Flame of Love, are all commentaries on his poems of the same titles. Influenced by The Song of Songs John uses the language of human love to express Divine love. His poetry is considered among the finest in the Spanish language, expressing the inexpressible: he takes ordinary language beyond itself. Paradoxically, his prose explains profound spiritual concepts in ways that everyone can understand. The aims of John’s writings are:
To help others to love and glorify God.
To lead others out of their pain and the misery of a sinful world.
Transforming union.
Transformation into Christ.
After a period of terrible physical and spiritual suffering, John died on 14th December 1592. He was canonised in 1726 and proclaimed a Doctor of the Church in 1926. His feast day is 14th December.
