In this volume, a world-renowned scholar of early Christianity updates and expands her classic survey of the writers and writings of the golden age of Greek patristic theology. This reliable guide to Christian literature from the late third century to the mid fifth century is more accessible than specialized works on individual authors but more informative than coverage provided by general histories and reference works. The second edition has been revised throughout for use by a new generation of students and scholars and includes a new chapter and updated bibliographies.
