Astutely reading the writings of early Christianity as part of the lively conversation of the Graeco-Roman world, Robert M. Grant helped reshape the study of the New Testament and early Christianity for scholars in the United States and Europe. Reading Religions in the Ancient World honors his work with sixteen essays by his colleagues and students, arranged under the headings of Classical Studies, New Testament Studies and Patristic Studies. These essays reflect and extend the research interests of the honoree; signal the breadth and depth of Professor Grant’s own scholarly interests and productivity; and contribute to each of these important aspects of religion in the ancient world.
