Born in poverty at at Fontiveros, Spain, John (1542-1591) cared for the sick and the poor in a hospital Medina. He became a lay Carmelite brother at age 21, and was ordained at the age of 25. Saint Teresa of Avila persuaded him to reform the Carmelite order, and he took the name John of the Cross. He later became the master of novices, spiritual director and confessor at Saint Teresa's convent. Some of his brothers did not approve of his reform, and he was ordered to go back to Medina. John refused and was imprisoned at Toledo, Spain. After nine months of staying there, he escaped. He later became a great contemplative and spiritual writer, and wrote the book, Dark Night of the Soul, a book of poems.
and canonized on the 27th of December, 1726, by Pope Benedict XIII
