Exploring the concept of the kingdom of God, this thesis is based on Patristic sources from the time of Clement of Rome to that of John of Damascus. Herrick begins with the Apostolic Fathers to set the stage for the major divisions that follow. Divided into the Ante-Nicene Fathers and the Nicene and Post-Nicene Fathers, the sources are divided into the Greek and Latin traditions and the major theologians and historic sources are examined for what they indicate about the theme. Written in non-technical language, this volume is readable by laity and specialists alike.
