A Brief History of Saints follows the rise of the cult of saints in Christianity from its origin in the age of the martyrs down to the present day. Referring to both well-known saints such as Joan of Arc and lesser-known figures like the "holy fools" in the Orthodox tradition, the book ranges over subjects as diverse as the history of canonization processes, the Reformation critique of the cult of saints, and the role of saints in other religious traditions.

While special attention is paid to the Western tradition, Eastern Christianity is also considered. The final chapters outline how the saints may serve as a theological resource, as well as discussing the relevance of sainthood in postmodern culture. The volume contains additional material on patron saints and the iconography of saints in art.
