This volume includes selections from the works of Athanasius, Gregory of Nazianzus, and Gregory of Nyssa. Through these works and those of other early Christian thinkers, this book surveys the development of early church theology.Long recognized for the quality of its translations, introductions, explanatory notes, and indexes, the Library of Christian Classics provides scholars and students with modern English translations of some of the most significant Christian theological texts in history. Through these works--each written prior to the end of the sixteenth century--contemporary readers are able to engage the ideas that have shaped Christian theology and the church through the centuries.
