John Macquarrie examines here, the lives and writings of a range of Christian mystics, both men and women, over a vast period of time - from Biblical times to present day. He presents their teachings, mostly in their own words, and shows how their ideas and the strength of their beliefs has brought great benefit to the Church over the course of history, and how they can continue to do so today. This is a hugely readable account of Christian mysticism, and its history; at an introductory level.
