"In the past, the peoples of the earth were variously distributed into provincial, national, and local governments. The consequences of this distribution were war and strife, depopulation and captivity. The origin of these calamities may justly be ascribed to the delusion of polytheistic error. But when the holy body of Christ was raised, the energy of these evil spirits was at once destroyed. The manifold forms of government were now no more. One God was proclaimed to all mankind, one empire prevailed, and the whole human race received one another as brethren. Thus, the whole world appeared like one well-ordered and united family and the ancient oracle and predictions of the prophets were fulfilled, 'And they shall beat their swords into plowshares, and their spears into sickles, and nation shall not take up sword against nation."Eusebius, bishop of Caesarea and Church historian, oration dedicated to the Roman emperor Constantine on the anniversary of the thirtieth year of his reign, Constantinople, 336 C.E.
