This is the first book in a series that includes scholarly volumes on the thought and history of early Christianity. It presents a systematic exploration of the thought and attitudes of Eusebius of Caesarea and Cyril of Jerusalem. After AD 325, when Constantine established his capital at Byzantium, the province of Palestine assumed a central importance and Christians were able to uncover the Gospel sites and to develop a theological approach to the Holy Land. This can be seen especially in the works of Eusebius and Cyril of Jerusalem, whose attitudes to Jerusalem and the holy places are here systematically compared for the first time, thus enabling the author to present a new appreciation of Eusebius. The book has relevance to the modern debate concerning the significance of the holy lands to the Christian denominations.
