Teresa of Avila was a Spanish nun of the sixteenth century whose visions of Christ and gifts as a spiritual director have placed her among the greatest of all Christian mystics.
She was the only daughter of a minor nobleman and entered the Carmelite convent in her native town of A’vil-a when she was twenty-one. Over the next two decades she endured many illnesses, one of which left her paralyzed, and also a nagging sense that in her prayers and devotions she was doing nothing more than “treading water.” Then, in answer to her despair, she began to have visions and hear “interior voices.” The most famous of these experiences, known as “transverberation of the heart,” took place over a number of days in 1559. At her left side Teresa beheld an angel who held a golden spear with a
flaming tip, with which he pierced her heart again and again. Teresa later wrote that each time the angel withdrew the spear she was "left completely afire with a great love for God,” and knew that her soul would “never be content with anything less than God.”
Three years later, in obedience to another vision, Teresa left her convent with thirteen other nuns to observe the primitive constitutions of the Carmelite Order in all their strictness. Despite fierce, sometimes violent opposition from the Carmelite establishment, Teresa eventually founded sixteen other Reformed Carmelite houses.
In the midst of her other concerns Teresa also found time to write a number of books, which reflect her holiness, wisdom, and sense of humour; and through them she has become one of the most widely loved saints in the Church, attractive even to those who have not shared her Spanish catholicism or her monastic vocation.
John of the Cross was the greatest Spanish mystic of the sixteenth century, and his writings still nourish modern Christians in their hunger for true experience in the spiritual life.
John was born in 1542, and became a Carmelite friar at the age of twenty-one. Four years later he met Teresa of Avila and joined in her reform of the Carmelite Order, serving as confessor to Teresa’s nuns. His prominence in the reform-movement made him a target of intrigues; twice he was abducted and imprisoned. After Teresa’s death he also suffered vindictive treatment at the hands of his own superiors in the Reformed Carmelites, and their harshness contributed to his death in 1591.
Through all his trials John was sustained by an intense mystical love for Jesus Christ. Like Teresa, he experienced the presence of Christ in “intellectual visions.” His reflection upon these experiences issued, first of all, in poetry of extraordinary power and beauty. At the urging of his disciples, he selected a number of his poems and produced prose commentaries on them, which have become classics of mystical theology. John united the vocation of a theologian with the experience of a mystic, and his writings are the supreme example of theology as the fruit of prayer.
