The Eastern reaction was therefore in its essence not Arian but conservative. Its leaders might be conservatives like Eusebius of Caesarea, or court politicians like his successor, Acacius. They were never open Arians till 357. The front and strength of the party was conservative, and the Arians at its tail were in themselves only a source of weakness. Yet they could enlist powerful allies in the cause of reaction. Heathenism was still a living power in the world. It was strong in numbers even in the East, and even stronger in the imposing memories of history. Christianity was still an upstart on Caesar's throne. The favour of the gods had built up the Empire, and men's hearts misgave them that their wrath might overthrow it. Heathenism was still an established religion, the Emperor still its official head. Old Rome was still devoted to her ancient deities, her nobles still recorded their priesthoods and augurships among their proudest honours, and the Senate itself still opened every sitting with an offering of incense on the altar of Victory. The public service was largely heathen, and the army too, especially its growing cohorts of barbarian auxiliaries. Education also was mostly heathen, turning on heathen classics and taught by heathen rhetoricians. Libanius, the teacher of Chrysostom, was also the honoured friend of Julian. Philosophy too was a great influence, now that it had leagued together all the failing powers of the ancient world against a rival not of this world. Its weakness as a moral force must not blind us to its charm for the imagination. Neoplatonism brought Egypt to the aid of Greece, and drew on Christianity itself for help. The secrets of philosophy were set forth in the mysteries of Eastern superstition. From the dim background of a noble monotheism the ancient gods came forth to represent on earth a majesty above their own. No waverer could face the terrors of that mighty gathering of infernal powers. And the Nicene age was a time of unsettlement and change, of half-beliefs and wavering superstition, of weakness and unclean frivolity. Above all, society was heathen to an extent we can hardly realise. The two religions were strangely mixed. The heathens on their side never quite understood the idea of worshipping one God only; while crowds of nominal Christians never asked for baptism unless a dangerous illness or an earthquake scared them, and thought it quite enough to show their faces in church once or twice a year. Meanwhile, they lived just like the heathens round them, steeped in superstitions like their neighbours, attending freely their immoral games and dances, and sharing in the sins connected with them. Thus Arianism had many affinities with heathenism, in its philosophical idea of the Supreme, in its worship of a demigod of the vulgar type, in its rhetorical methods, and in its generally lower moral tone. Heathen influences therefore strongly supported Arianism. [Sidenote: (2.) Jews.]
