devotion dominated or displaced all national feeling. We know the oaths taken by those subjects to their deified kings.^[7] They agreed to defend and uphold them even at the cost of their own lives, and always to have the same friends and the same enemies as they; they dedicated to them not only their actions and words, but their very thoughts. Their duty was a complete abandonment of their personality in favor of those monarchs who were held the equals of the gods. The sacred militia of the mysteries was nothing but this civic

morality viewed from the religious standpoint. It confounded loyalty with piety.

As we see, the researches into the doctrines or practices common to Christianity and the Oriental mysteries lead almost always beyond the limits of the Roman empire into the Hellenistic Orient. The religious conceptions which imposed themselves on Latin Europe under the Cæsars^[8] were developed there, and it is there we must look for the key to enigmas still unsolved. It is true that at present nothing is more obscure than the history of the religions that arose in Asia when Greek culture came in contact with barbarian theology. It is rarely possible to formulate satisfactory conclusions with any degree of certainty, and before further discoveries are made we shall frequently be compelled to weigh contrasting probabilities. We must frequently throw out the sounding line into the shifting sea of possibility in order to find secure anchorage. But at any rate we perceive with sufficient distinctness the direction in which the investigations must be pursued.

It is our belief that the main point to be cleared up is the composite religion of those Jewish or Jewish-pagan communities, the worshipers of Hypsistos, the Sabbatists, the Sabaziasts and others in which the new creed took root during the apostolic age. In those communities the Mosaic law had become adapted to the sacred usages of the Gentiles even before the beginning of our era, and monotheism had made concessions to idolatry. Many beliefs of the ancient Orient, as for instance the ideas of Persian dualism regarding the infernal world, arrived in Europe by two roads, the more or less orthodox Judaism of the communities of

the dispersion in which the gospel was accepted immediately, and the pagan mysteries imported from Syria or Asia Minor. Certain similarities that surprised and shocked the apologists will cease to look strange as soon as we reach the distant sources of the channels that reunited at Rome.

But these delicate and complicated researches into origins and relationships belong especially to the history of the Alexandrian period. In considering the Roman empire, the principal fact is that the Oriental religions propagated doctrines, previous to and later side by side with Christianity, that acquired with it universal authority at the decline of the ancient world. The preaching of the Asiatic priests also unwittingly prepared for the triumph of the church which put its stamp on the work at which they had unconsciously labored.

Through their popular propaganda they had completely disintegrated the ancient national faith of the Romans, while at the same time the Cæsars had gradually destroyed the political particularism. After their advent it was no longer necessary for religion to be connected with a state in order to become universal. Religion was no longer regarded as a public duty, but as a personal obligation; no longer did it subordinate the individual to the city-state, but pretended above all to assure his welfare in this world and especially in the world to come. The Oriental mysteries offered their votaries radiant perspectives of eternal happiness. Thus the focus of morality was changed. The aim became to realize the sovereign good in the life hereafter instead of in this world, as the Greek philosophy had done. No longer did man act in view of tangible

realities, but to attain ideal hopes. Existence in this life was regarded as a preparation for a sanctified life, as a trial whose outcome was to be either everlasting happiness or everlasting pain.

As we see, the entire system of ethical values was overturned.

The salvation of the soul, which had become the one great human care, was especially promised in these mysteries upon the accurate performance of the sacred ceremonies. The rites possessed a power of purification and redemption. They made man better and freed him from the dominion of hostile spirits. Consequently, religion was a singularly important and absorbing matter, and the liturgy could be performed only by a clergy devoting itself entirely to the task. The Asiatic gods exacted undivided service; their priests were no longer magistrates, scarcely citizens. They devoted themselves unreservedly to their ministry, and demanded of their adherents submission to their sacred authority.

All these features that we are but sketching here, gave the Oriental religions a resemblance to Christianity, and the reader of these studies will find many more points in common among them. These analogies are even more striking to us than they were in those times because we have become acquainted in India and China with religions very different from the Roman paganism and from Christianity as well, and because the relationships of the two latter strike us more strongly on account of the contrast. These theological similarities did not attract the attention of the ancients, because they scarcely conceived of the existence of other possibilities, while differences were what they

remarked especially. I am not at all forgetting how considerable these were. The principal divergence was that Christianity, by placing God in an ideal sphere beyond the confines of this world, endeavored to rid itself of every attachment to a frequently abject polytheism. But even if we oppose tradition, we cannot break with the past that has formed us, nor separate ourselves from the present in which we live. As the religious history of the empire is studied more closely, the triumph of the church will, in our opinion, appear more and more as the culmination of a long evolution of beliefs. We can understand the Christianity of the fifth century with its greatness and weaknesses, its spiritual exaltation and its puerile superstitions, if we know the moral antecedents of the world in which it developed. The faith of the friends of Symmachus was much farther removed from the religious ideal of Augustus, although they would never have admitted it, than that of their opponents in the senate. I hope that these studies will succeed in showing how the pagan religions from the Orient aided the long continued effort of Roman society, contented for many centuries with a rather insipid idolatry, toward more elevated and more profound forms of worship. Possibly their credulous mysticism deserves as much blame as is laid upon the theurgy of neo-Platonism, which drew from the same sources of inspiration, but like neo-Platonism it has strengthened man's feeling of eminent dignity by asserting the divine nature of the soul. By making inner purity the main object of earthly existence, they refined and exalted the psychic life and gave it an almost supernatural intensity, which until then was unknown in the ancient world.
