St. John left the following works, which for the first time appeared at Barcelona in 1619.
* "The Ascent of Mount Carmel", an explanation of some verses beginning: "In a dark night with anxious love inflamed". This work was to have comprised four books, but breaks off in the middle of the third.
* "The Dark Night of the Soul", another explanation of the same verses, breaking off in the second book. Both these works were written soon after his escape from prison, and, though incomplete, supplement each other, forming a full treatise on mystic theology.
* An explanation of the "Spiritual Canticle", (a paraphrase of the Canticle of Canticles) beginning "Where hast Thou hidden Thyself?" composed part during his imprisonment, and completed and commented upon some years later at the request of Venerable Anne of Jesus.
* An explanation of a poem beginning: "O Living Flame of Love", written about 1584 at the bidding of Dona Ana de Penalosa.
* Some instructions and precautions on matters spiritual.
* Some twenty letters, chiefly to his penitents. Unfortunately the bulk of his correspondence, including numerous letters to and from St. Teresa, was destroyed, partly by himself, partly during the persecutions to which he fell a victim.
* "Poems", of which twenty-six have been hitherto published, viz., twenty in the older editions, and recently six more, discovered partly at the National Library at Madrid, and partly at the convent of Carmelite nuns at Pamplona.
* "A Collection of Spiritual Maxims" (in some editions to the number of one hundred, and in others three hundred and sixty-five) can scarcely count as an independent work, as they are culled from his writings.
