The century and a quarter following the Council of Nicaea (AD325) has been called the 'Golden Age of Patristic Literature'. It is this period that Henry Bettenson covers in this companion volume to The Early Christian Fathers, selecting from the writings of Basil the Great, Gregory of Nyssa, Jerome, Augustine of Hippo, Cyril of Alexandria, and other Fathers of the Christian Chruch. Their central concerns were to formulate the doctrine of the Trinity after the Nicene conclusions, and to enunciate the doctrine of the divinity ahd humanity of Christ. The writings served to clarify if not to solve the issues and they continue to be value and relevant for all who wish to understand Christian doctrine. As in The Early Christian Fathers, Bettenson translated everything afresh and provided some annotation and brief sketches of the lives of each of the Fathers represented in the selection.
