Thomas Merton's lectures to the young monastics at the Abbey of Gethsemani provide a good look at Merton the scholar. A Course in Christian Mysticism gathers together, for the first time, the best of these talks into a spiritual, historical, and theological survey of Christian mysticism -- from St. John's gospel to St. John of the Cross. Sixteen centuries are covered over thirteen lectures. A general introduction sets the scene for when and how the talks were prepared and for the perennial themes one finds in them, making them relevant for spiritual seekers today. This compact volume allows anyone to learn from one of the twentieth century's greatest Catholic spiritual teachers. The study materials at the back of the book, including additional primary source readings and thoughtful questions for reflection and discussion, make this an essential text for any student of Christian mysticism.
