In A Companion to Jesuit Mysticism, Robert A. Maryks provides thirteen unique essays discussing the Jesuit mystical tradition, a somewhat neglected aspect of Jesuit historiography that stretches as far back as the order’s co-founder, Ignatius of Loyola, his spiritual visions at Manresa, and ultimately the mystical perspective contained in his Spiritual Exercises. The volume’s contributions on the most significant representatives of the Jesuit mystical tradition—from Baltasar Álvarez to Louis Lallemant to Hugo Makibi Enomiya-Lassalle—aim to fill this lacuna in Jesuit historiography. Although intended primarily as a handbook for scholars seeking to further their own research in this area, the volume will undoubtedly be of interest to scholars and students of Jesuit studies more broadly.
