The rise of the Roman empire opened the western European world to this growing cult. The temples of Serapis-Isis, the chanting of the priests and the hope of immortal life, followed the Roman standards to Scotland and Holland. But there were many rivals to the Serapis-Isis religion. Prominent among these was Mithraism. This was a religion of Persian origin, and it centred upon some now forgotten mysteries about Mithras sacrificing a sacred and benevolent bull. Here we seem to have something more primordial than the complicated and sophisticated Serapis-Isis beliefs. We are carried back directly to the blood sacrifices of the heliolithic stage in human culture. The bull upon the Mithraic monuments always bleeds copiously from a wound in its side, and from this blood springs new life. The votary to Mithraism actually bathed in the blood of the sacrificial bull. At his initiation he went beneath a scaffolding upon which a bull was killed so that the blood could actually run down on him.

Both these religions, and the same is true of many other of the numerous parallel cults that sought the allegiance of the slaves and citizens under the earlier Roman emperors, are personal religions. They aim at personal salvation and personal immortality. The older religions were not personal like that; they were social. The older fashion of divinity was god or goddess of the city first or of the state, and only secondarily of the individual. The sacrifices were a public and not a private function. They concerned collective practical needs in this world in which we live. But the Greeks first and now the Romans had pushed religion out of politics. Guided by the Egyptian tradition religion had retreated to the other world.

These new private immortality religions took all the heart and emotion out of the old state religions, but they did not actually replace them. A typical city under the earlier Roman emperors would have a number of temples to all sorts of gods. There might be a temple to Jupiter of the Capitol, the great god of Rome, and there would probably be one to the reigning Cæsar. For the Cæsars had learnt from the Pharaohs the possibility of being gods. In such temples a cold and stately political worship went on; one would go and make an offering and burn a pinch of incense to show one’s loyalty. But it would be to the temple of Isis, the dear Queen of Heaven, one would go with the burthen of one’s private troubles for advice and relief. There might be local and eccentric gods. Seville, for example, long affected the worship of the old Carthaginian Venus. In a cave or an underground temple there would certainly be an altar to Mithras, attended by legionaries and slaves. And probably also there would be a synagogue where the Jews gathered to read their Bible and uphold their faith in the unseen God of all the Earth.

Sometimes there would be trouble with the Jews about the political side of the state religion. They held that their God was a jealous God intolerant of idolatry, and they would refuse to take part in the public sacrifices to Cæsar. They would not even salute the Roman standards for fear of idolatry.

In the East long before the time of Buddha there had been ascetics, men and women who gave up most of the delights of life, who repudiated marriage and property and sought spiritual powers and an escape from the stresses and mortifications of the world in abstinence, pain and solitude. Buddha himself set his face against ascetic extravagances, but many of his disciples followed a monkish life of great severity. Obscure Greek cults practised similar disciplines even to the extent of self-mutilation. Asceticism appeared in the Jewish communities of Judea and Alexandria also in the first century B.C. Communities of men abandoned the world and gave themselves to austerities and mystical contemplation. Such was the sect of the Essenes. Throughout the first and second centuries A.D. there was an almost world-wide resort to such repudiations of life, a universal search for “salvation” from the distresses of the time. The old sense of an established order, the old confidence in priest and temple and law and custom, had gone. Amidst the prevailing slavery, cruelty, fear, anxiety, waste, display and hectic self-indulgence, went this epidemic of self- disgust and mental insecurity, this agonized search for peace even at the price of renunciation and voluntary suffering. This it was that filled the Serapeum with weeping penitents and brought the converts into the gloom and gore of the Mithraic cave.

THE TEACHING OF JESUS

It was while Augustus Cæsar, the first of the Emperors, was reigning in Rome that Jesus who is the Christ of Christianity was born in Judea. In his name a religion was to arise which was destined to become the official religion of the entire Roman Empire.
