The century and a quarter following the Council of Nicaea (A.D. 325) 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 Church. Their central concerns were formulating the doctrine of the Trinity after the Nicene conclusions, and enunciating the doctrine of the divinity and humanity of Christ. The writings served to clarify if not to solve the issues and they continue to be valuable and relevant for all who wish to understand the Christian doctrine. As in The Early Christian Fathers, Mr. Bettenson has translated everything afresh and provided some brief sketches of the lives of each of the Fathers represented in the selection.
