A number of good anthologies of the Christian mystics have been published over the years; this one is certainly one of my favorites. Arranged topically rather than chronologically, it provides an overview not only of the literature of mysticism but of the breadth of ideas and wisdom that mystical theology and spiritual teaching entails. Topics include Biblical interpretation, asceticism and purgation, prayer and the sacraments, mystical practices, vision, contemplation, rapture, deification, and union with God. Final sections examine the relationships between mysticism and heresy, and between contemplation and action. All the major mystical writers of the Christian tradition are included, making this a comprehensive overview of the tradition; and McGinn’s perceptive commentary make the texts come alive.
