This book is the first systematic discussion of the theological contribution of John Chrysostom, a seminal figure in the Christian homiletical tradition. His ministry in the late fourth and early fifth centuries marked him as the leading Greek expositor of the Patristic period. This book develops the basic motifs of Chrysostom's thought and gives an overview of the entire range of his contribution. Chrysostom's theology of pastoral ministry, the Christian life, sexual relations, and Church and state receive particular attention. This book will be of interest to all students of the Christian ministry, the Patristic period and the history of Christian theology.
