Even before Eckhart’s posthumous condemnation, the church struck out against the mystics. The Council of Vienne condemned their errors in 1311, shortly after Marguerite Porete was burned as a heretic for continuing to disseminate her book, The Mirror of Simple Souls. Marguerite’s work was a highly popular treatise and handbook that described the seven stages of the ascent to God and maintained that the soul could achieve union with God while still on earth. The council associated these views with the Beguines, groups of religious women who did not live in cloister or follow a recognized rule of life. The council also denounced the Beghards, a group of heretical mystics who were the male counterparts of the Beguines and were often associated with them, for their antinomian and libertine views. In the centuries that followed, some mystics were condemned and others executed, though evidence for a widespread “mystical heresy” is lacking.
The great mystical writers of the late Middle Ages, however, took pains to prove their orthodoxy. Eckhart’s followers among the Rhineland mystics, especially Heinrich Suso and Johann Tauler, defended his memory but qualified his daring language. Texts such as the anonymous Theologia Germanica of the late 14th century, which reflects the ideas of the loose groups of mystics who called themselves the Friends of God, conveyed this German mysticism to the Reformers. The rich mystical literature that developed in the Low Countries reached its culmination in writings of Jan van Ruysbroeck (1293–1381). In Italy two remarkable women, Catherine of Siena in the 14th century and Catherine of Genoa in the 15th, made important contributions to the theory and practice of mysticism. The 14th century also was the “Golden Age” of English mysticism, as conveyed in the writings of the hermit Richard Rolle; the canon Walter Hilton, who wrote The Scale (or Ladder) of Perfection; the anonymous author of The Cloud of Unknowing; and his contemporary, the visionary recluse Julian of Norwich, whose Revelations of Divine Love is unsurpassed in English mystical literature. Julian’s meditations on the inner meaning of her revelations of the crucified Christ express the mystical solidarity of all humanity in the Redeemer, who is conceived of as a nurturing mother.
In the 16th century the centre of Roman Catholic mysticism shifted to Spain, the great Roman Catholic power at the time of the Reformation. Important mystics came both from the traditional religious orders, such as Francis de Osuna among the Franciscans, Luis de León among the Augustinians, and Luis de Grenada among the Dominicans, and from the new orders, as with Ignatius of Loyola, the founder of the Jesuits. The two pillars of Spanish mysticism, however, were Teresa of Ávila (1515–82) and her friend John of the Cross (1542–91), both members of the reform movement in the Carmelite order. Teresa’s Life is one of the richest and most convincing accounts of visionary and unitive experiences in Christian mystical literature; her subsequent synthesis of the seven stages on the mystical path, The Interior Castle, has been used for centuries as a basic handbook. John of the Cross was perhaps the most profound and systematic of all Roman Catholic mystical thinkers. His four major works, The Dark Night of the Soul, The Ascent of Mount Carmel, The Spiritual Canticle, and The Living Flame of Love, constitute a full theological treatment of the active and passive purgations of the sense and the spirit, the role of illumination, and the unification of the soul with God in spiritual marriage.
In the 17th century France took the lead with figures such as Francis of Sales, Pierre de Bérulle, Brother Lawrence (the author of The Practice of the Presence of God), and Marie Guyard. At this time concentration on the personal experience of the mystic as the source for “mystical theology” (as against the common scriptural faith and sacramental life of the church) led to the creation of mysticism as a category and the description of its adherents as mystics. At the same time, the rise of the Quietist controversy brought about renewed conflict over mysticism. A Spaniard resident in Rome, Miguel de Molinos, author of the popular Spiritual Guide (1675), was condemned for his doctrine of the “One Act,” that is, the teaching that the will, once fixed on God in contemplative prayer, cannot lose its union with the divine. In France Mme Guyon and her adviser, François Fénelon, archbishop of Cambrai, were also condemned for Quietist tendencies emphasizing the role of pure love to the detriment of ecclesiastical practice. These debates cast a pall over the role of mysticism in Roman Catholicism into the 20th century, though important mystics continued to be found, most notably Thomas Merton and Pope John Paul II. Bernard J. McGinn Protestant Christianity
The chief representatives of Protestant mysticism are the continental “Spirituals,” among whom Sebastian Franck (c. 1499–c. 1542), Valentin Weigel (1533–88), and Jakob Böhme (1575–1624) are especially noteworthy. Among traditional Lutherans Johann Arndt (1555–1621) in his Four Books on True Christianity took up many of the themes of medieval mysticism in the context of Reformation theology and prepared the way for the spiritual revival known as Pietism, within which mystics such as Count von Zinzendorf flourished. The important mystics in England included the Cambridge Platonists (a group of Anglican divines), the Quakers, and William Law (1686–1761). In Holland a mystical group known as Collegiants, similar to the Quakers, broke away from the Remonstrant (Calvinist) Church. Other groups of mystics were the Schwenckfeldians, founded by Kaspar Schwenckfeld, and the Family of Love, founded in Holland by Hendrik Niclaes in about 1540. He later made two trips to England, where his group had its largest following and survived into the 17th century. The religion of the Ranters and other radical Puritans in 17th-century England also had mystical aspects.
Protestant mysticism emphasized the divine element in humanity, which was called the “spark” or “ground” of the soul, the “divine image” or “holy self,” the “Inner Light,” or the “Christ within.” This was one of the essential elements of Rhineland mysticism and shows the connection between medieval and Reformation mysticism. For Böhme and the Spirituals, essential reality lies in the ideal world, which Böhme described as “the uncreated Heaven.” Böhme adopted the Gnostic belief that the physical world arose from a primeval fall, renewed with the Fall of Adam. His teaching was the main formative influence on the developed outlook of William Law and William Blake (1757–1827).
For Protestant as well as for Roman Catholic mystics, sin is the assertion of the self in its separation from God. The divine life is embodied in “the true holy self that lies within the other” (Böhme, First Epistle). When that self is manifested, there is a birth of God (or of Christ) in the soul. Protestant mystics rejected the Lutheran and Calvinist doctrine of the total corruption of human nature. William Law remarked, “The eternal Word of God lies hid in thee, as a spark of the divine nature” (The Spirit of Prayer, I.2). “The eternal Word of God” is the inner Christ, incarnate whenever people rise into union with God. The Spirituals also viewed Christ as the ideal humanity born in God from all eternity. This conception received its greatest emphasis from Schwenckfeld, who, unlike Protestant mystics generally, taught that humans as created beings are totally corrupt; salvation means deliverance from the creaturely nature and union with the heavenly Christ.
