<p>This small book, the last work of a world-renowned scholar, has established itself as a classic. It provides a superb overview of the vast historical process by which Christianity was Hellenized and Hellenic civilization became Christianized. </p><p>Jaeger shows that without the large postclassical expansion of Greek culture the rise of a Christian world religion would have been impossible. He explains why the Hellenization of Christianity was necessary in apostolic and postapostalic times; points out similarities between Greek philosophy and Christian belief; discuss such key figures as Clement, Origen, and Gregory of Nyssa; and touches on the controversies that led to the ultimate complex synthesis of Greek and Christian thought. </p>
