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. He was a reformer of the Carmelite Order and was considered, along with Saint Teresa of Ávila, as a founder of the Discalced Carmelites. He was 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 was one of the thirty-five Doctors of the Church.
