Born in Fantiveros, Castile, in Spain, John became a Carmelite monk in 1564. He studied philosophy and theology at the Carmelite college in Salamanca, one of Europe's leading universities. In 1567, the year he was ordained, he met with Teresa of Avila. Teresa saw great potential in John and put him in charge of the order. She admired his rigorous life-style and leadership ability. She was not disappointed, as John was able to establish several new orders.
It was during this time that he was name "John of the Cross," as a result of his suffering and commitment. He spent the rest of his life in the service of the Catholic Reform through his leadership and many writings. He was eventually arrested and put in confinement by those who opposed the reform. It was in confinement that his most famous work, The Dark Night of the Soul, was written. It describes the work of God upon the soul—not through joy and light, but through sorrow and darkness. The concept of "dark night" has become an integral part of understanding the spiritual journey. Though he died centuries ago, John of the Cross continues to exercise a significant influence on Christian spirituality.
Francis de Sales was born into a noble family at the castle of Sales and later attended a Jesuit school in Paris. The Jesuits taught him the classics, Hebrew, Greek, and the life of discipline. His training also included the study of law and the humanities. He was ordained a priest in 1591 despite opposition from his family. In 1602 he became bishop of Geneva.
Francis was a prolific writer whose works had a great influence on the church. He combined spiritual depth with ethical concern in a way the few writers, before or after him, have been able to do. He was a master of metaphor, describing the mysteries of the spiritual life through simple everyday images like bees and milk, birds and sugar. Because of his considerable influence, Francis is considered one of "the doctors of the Western Church."
Jonathan Edwards was a Congregational pastor and a key figure in the eighteenth-century "Great Awakening." He is considered one of America's greatest theologians. Born in Connecticut and educated at Yale, he ministered for twenty-three years at a church in Northampton, Massachusetts. He later became a missionary to the Indians at Stockbridge. In 1758 he was named president of Princeton University but died only a few weeks after taking office.
Edwards produced a theology of Christian spirituality for his age that blended together Lockean philosophy and his own Calvinist theology. His main concern was the question, How do we distinguish the presence of the Holy Spirit? Christian experience, according to Edwards, is a gift of God, but he spent his life working out the ways in which we define that experience. A central theme of his writings is the importance of religious "affections," which he defined as the passions that move the will to act.
Clive Staples Lewis will be remembered as one of the most important Christian thinkers of the twentieth century. He was born in Ireland in 1898, and the major part of his adult years was spent as a Fellow of Magdalen College, Oxford, where he taught medieval literature. It was in 1931 that he was "surprised by joy," Lewis's own description of his conversion to Christianity. A brilliant scholar and writer, Lewis used his talents to reach thousands through the printed and spoken word.
He and a group of friends (including J. R. R. Tolkien, author of Lord of the Rings) gathered once a week to share their writings. During those years Lewis produced his famous work The Screwtape Letters. In the early 1940s he delivered talks on various Christian topics over British radio. His fame grew throughout Great Britain and spread to the United States. Out of those talks came the book Mere Christianity, a penetrating work on Christian apologetics. Countless Christians point to this book as an essential part of their faith journey. If sales are an indication of popularity, then C. S. Lewis is one of the most popular Christian thinkers of the twentieth century.
