St. Juan of the Cross, the fellow-workman of St. Teresa in the reform of monasteries, is a still more perfect example of the Spanish type of Mysticism. His fame has never been so great as hers; for while Teresa's character remained human and lovable in the midst of all her austerities, Juan carried self-abnegation to a fanatical extreme, and presents the life of holiness in a grim and repellent aspect. In his disdain of all compromise between the claims of God and the world, he welcomes every kind of suffering, and bids us choose always that which is most painful, difficult, and humiliating. His own life was divided between terrible mortifications and strenuous labour in the foundation of monasteries. Though his books show a tendency to Quietism, his character was one of fiery energy and unresting industry. Houses of "discalced" Carmelites sprang up all over Spain as the result of his labours. These monks and nuns slept upon bare boards, fasted eight months in the year, never ate meat, and wore the same serge dress in winter and summer. In some of these new foundations the Brethren even vied with each other in adding voluntary austerities to this severe rule. It was all part of the campaign against Protestantism. The worldliness and luxury of the Renaissance period were to be atoned for by a return to the purity and devotion of earlier centuries. The older Catholic ideal--the mediæval type of Christianity--was to be restored in all its completeness in the seventeenth century. This essentially militant character of the movement among the Carmelites must not be lost sight of: the two great Spanish mystics were before all things champions of the counter-Reformation. The two chief works of St. Juan are _The Ascent of Mount Carmel_, and _The Obscure Night of the Soul_. Both are treatises on quietistic Mysticism of a peculiar type. At the beginning of _La Subida de Monte Carmelo_ he says, "The journey of the soul to the Divine union is called _night_ for three reasons: the point of departure is privation of all desire, and complete detachment from the world; the road is by faith, which is like night to the intellect; the goal, which is God, is incomprehensible while we are in this life."
