"This study really is an 'introduction' and is well suited to the needs of undergraduate students in universities, theological colleges, and seminaries. The book will also be useful for adult education courses, and will appeal in addition to a more general readership. There is a need for a reliable, basic, introductory textbook like this that doesn't make too many assumptions about its readers." Philip Sheldrake, Vice-Principal, Sarum College, Salisbury

"I am sure that this book will have a wide readership, particularly among theologians and students of theology. It should also have a wider readership among Christians more generally. Existing works of spirituality often have limited scope and make assumptions about their readers' knowledge. The author's concern to fill gaps and provide adequate explanations and contexts is admirable." Robert Swanson, Reader in Medieval History, University of Birmingham

"[The book's] considerable advantage in accessibility and in the structured ordering of ideas makes it ideal as an undergraduate textbook or a committed interest-reader's introduction. It includes frequent invitations and injunctions to read and explore more deeply. The book is written with superb clarity and very considerable breadth of reference...As a working textbook, this has everything one could wish for: interaction with the reader in the form of suggested tasks and internal cross-references; good management of the interrelationship with theology and clarification of terms; window-box texts; a glossary; a list of websites. For university courses and libraries this is a must. For enquirers it is a scholarly and accessible guide." International Journal of Children's Spirituality

"This book is highly recommended as a college or seminary textbook on the spiritual life or sanctification. In addition, anyone interested in delving into the tradition of Christian spirituality will find this a useful guide." Bibliotheca Sacra
