Jordan Aumann's new book has been written as a companion to his firmly established Spiritual Theology, in which he set out the theological principles which constitute the doctrinal basis of the ascetical and mystical life. Christian Spirituality in the Catholic Tradition he moves from theory to life and witness: this history not only serves to acquaint us with the origins and development of Christian spirituality, but, equally importantly in the author's view, projects into our contemporary world the lives and teachings of men and women who have reached a high degree of sanctity through the ages.
