Such legends are eloquent; they disclose the daring wishes of the Christians and show that they no longer thought the empire and Christianity incompatible. This is likewise evident from the fact that this same Dionysius does not shrink from applying a Messianic prophecy in the Old Testament to the emperor Valerian. Gallienus had cancelled his father’s writ for the persecution of Christians, and Dionysius therefore applies to him the prophecy of Isaiah, and styles him, moreover, “our sanctified emperor, well-pleasing in God’s sight.” This is the very language which Christian bishops used of Constantine sixty years later. Secondly, it is a significant token of change that Origen, in his great work against Celsus, written towards the end of his life, in the reign of the emperor Philip, expressed the hope that by gradual advances Christianity would attain to victory in this world. This is the exact opposite of what primitive Christians had believed and hoped. Origen could not have put the anticipation into words, unless, in spite of all the differences which still subsisted between state and church, these two great powers had drawn considerably nearer to each other. At bottom the only question was that of the removal of “misunderstandings”; in actual fact, nothing blocked the way to the conclusion of peace except the church’s demand not for mere toleration but for exclusive recognition.

In the foregoing pages we have shown how the church, as it developed, drew nearer to the state; all that now remains to be done is to point out how, in the second century, and still more in the third, the state, on its part, drew nearer to the Christian religion and to the church. I will confine myself to a few suggestive indications.
(1) During the imperial period the Roman state wielded no real influence upon the religious life of the citizens of its domains, except by means of the worship of the emperors; the other Roman cults were of local importance only, and were perpetually being thrust into the background by alien religions. Under these circumstances the state had made an attempt to develop emperor worship into the actual universal religion of the empire. Sagacious statesmen and religious politicians were, however, constrained to own that this cult, the adoration of the
A single, new, universal religion was the crying need of the hour. It seemed that this need might be met in various ways. Elagabalus, Alexander Severus, and Maximinus Daza were the emperors who tried to strike out a fresh line before the time of Constantine. Elagabalus wished to do this by exalting one Syrian divinity to the position of Supreme God of the empire and giving a subordinate place to all other cults; Alexander, by endeavouring to discover the common element in all religious doctrines and forms of worship and uniting them in peaceful conjunction (as all, at bottom, meaning the same thing); Maximinus Daza by making regulations for the administrative union of all the religions and cults of a single province under one high priest appointed by the state, and for the control of these priests by the civil government. These were all attempts to create a new church, and an established church to boot, and must all be regarded as preliminaries to Constantine’s achievement.
A certain bias towards monotheism was involved in the case of Elagabalus and Alexander; towards an oriental monotheism in the former. Diocletian, indeed, attempted once more to make the old Roman religious system serve the purpose; but as he had placed the political administration and government of the empire on an entirely new basis, and introduced a new oriental and despotic system after the dissolution of the ancient state, his reactionary religious policy was a grave error. It was foredoomed to utter failure—the new state could not possibly rest upon the scanty foundations of the old cults; and Constantine, who witnessed its collapse, drew from it the only correct inference. The new basis of the state must be a monotheistic religion—an oriental monotheism. So much the third century had taught.
