In the second volume of this collection, Koester continues his look at early Christianity, examining its historical development through its canonical and non-canonical literature. Using an engaging chronological and geographical approach, he thoroughly examines the New Testament and the world from which it emerged. Throughout this text, he provides readers with insight into how the New Testament books were written and his argument as to their intent. He examines numerous biblical figures including John the Baptist and several apostles who established early Christian churches, while giving some attention to examining early Christian writings from a literary perspective.
