{119} 13. End of Pagan Persecution.--This, however, was to be the last great persecution of the Christians by the heathens. In 305 Diocletian, to the surprise of his own and all succeeding ages, resigned the empire and compelled his associate, Maximian, to do the same. This left the empire in the hands of the two Caesars, who became the emperors. Like their predecessors they chose colleagues; but Constantius Chlorus, dying at York, in Britain, his son, Constantine [Kon-stan-tin], afterwards called the Great, was proclaimed emperor by the army. The associate of his father, Galerius, and the two Caesars refused to ratify the election, and civil war ensued which lasted for eighteen years. Finally, however, Constantine prevailed over all his rivals and became sole emperor, A. D., 323. Being, like his father, favorably disposed towards Christianity, his accession to the throne brought universal peace to the church. 14. The Luminous Cross Seen by Constantine.--It was during the above-mentioned civil war, while marching against the forces of Maxentius [Max-en-ti-us], one of the rebellious Caesars, that Constantine and his army are said to have seen near midday, in the heavens, a luminous cross bearing this inscription in Greek: "By This Conquer." The same night Christ appeared to him in a dream accompanied with the same sign and instructed him to make a standard bearing the cross as a protection against his enemies. The circumstance is related at great length in the life of Constantine by Eusebius, on whose sole authority the story rests. It is regarded as suspicious that he makes no reference to the matter in Ecclesiastical History, written only twelve years after the event. (See note 7, end of section.) The story is altogether rejected by some writers as the cunning invention of interested priests seeking to make the cross an object of veneration; and even Christian writers of high standing--among them Mosheim--consider the story to be doubtful. 15. Constantine and his Friendliness to Christianity.--With {120} the accession of Constantine to the imperial throne, as before remarked, the peace of the church was assured. His father had favored the Christians, and in the cruel persecution under Diocletian, he kept the provinces of Gaul free from the effusion of Christian blood; and his son seems to have fallen heir to his father's friendliness for the Christian faith.
