Book excerpt: The development of Christianity from its origins through its first five centuries is a complex story, for during this period it grew from a small and obscure sect to become the major religious force within the Roman Empire. It was during these early years that the Church established the New Testament and came to agreement on such questions as the Resurrection and the Trinity. Creeds, liturgies, theology, the moral and aesthetic fabric of Christian living were all formed in this period. The predominant feature of this book is its simplicity of organization. After setting forth the context of the Jewish community into which Jesus was born, Davies treats each of the five centuries in a separate chapter divided into background, sources, expansion and development, beliefs, worship, and social life. Thus the reader can easily follow any single topic through the whole period or get a reliable view of them all within any one century.--From publisher description.
