St. John of the Cross

Saint John of the Cross, O.C.D. (Spanish: San Juan de la Cruz; 1542 - 14 December 1591), was a major figure of the Counter-Reformation, a Spanish mystic, a Roman Catholic saint, a Carmelite friar and a priest who was born at Fontiveros, Old Castile.

John of the Cross was a reformer of the Carmelite Order and is considered, along with Saint Teresa of Ávila, as a founder of the Discalced Carmelites. He is also known for his writings. Both his poetry and his studies on the growth of the soul are considered the summit of mystical Spanish literature and one of the peaks of all Spanish literature. He was canonized as a saint in 1726 by Pope Benedict XIII. He is one of the thirty-five Doctors of the Church.

Ascent of Mount Carmel (Spanish: Subida del Monte Carmelo) is a 16th-century spiritual treatise by Spanish Catholic mystic and poet Saint John of the Cross. The book is a systematic treatment of the ascetical life in pursuit of mystical union with Christ, giving advice and reporting on his own experience. Alongside another connected work by John, entitled The Dark Night, it details the so-called Dark Night of the Soul, when the individual Soul undergoes earthly and spiritual privations in search of union with God. These two works, together with John's The Living Flame of Love and the Spiritual Canticle, are regarded as some of the greatest works both in Christian mysticism and in the Spanish language.

Written between 1578 and 1579 in Granada, Spain, after his escape from prison, the Ascent is illustrated by a diagram of the process outlined in the text of the Soul's progress to the summit of the metaphorical Mount Carmel where God is encountered. The work is divided into three sections and is set out as a commentary on four poetic stanzas by John on the subject of the Dark Night. John shows how the Soul sets out to leave all worldly ties and appetites behind to achieve "nothing less than transformation in God".

Dark Night of the Soul (Spanish: La noche oscura del alma) is the title of a poem written by 16th-century Spanish poet and Roman Catholic mystic Saint John of the Cross, and of a treatise he wrote later, commenting on the poem.
