Chief among the makers of Christian doctrine was St. Paul. He had never seen Jesus nor heard him preach. Paul’s name was originally Saul, and he was conspicuous at first as an active persecutor of the little band of disciples after the crucifixion. Then he was suddenly converted to Christianity, and he changed his name to Paul. He was a man of great intellectual vigour and deeply and passionately interested in the religious movements of the time. He was well versed in Judaism and in the Mithraism and Alexandrian religion of the day. He carried over many of their ideas and terms of expression into Christianity. He did very little to enlarge or develop the original teaching of Jesus, the teaching of the Kingdom of Heaven. But he taught that Jesus was not only the promised Christ, the promised leader of the Jews, but also that his death was a sacrifice, like the deaths of the ancient sacrificial victims of the primordial civilizations, for the redemption of mankind. When religions flourish side by side they tend to pick up each other’s ceremonial and other outward peculiarities. Buddhism, for example, in China has now almost the same sort of temples and priests and uses as Taoism, which follows in the teachings of Lao Tse. Yet the original teachings of Buddhism and Taoism were almost flatly opposed. And it reflects no doubt or discredit upon the essentials of Christian teaching that it took over not merely such formal things as the shaven priest, the votive offering, the altars, candles, chanting and images of the Alexandrian and Mithraic faiths, but adopted even their devotional phrases and their theological ideas. All these religions were flourishing side by side with many less prominent cults. Each was seeking adherents, and there must have been a constant going and coming of converts between them. Sometimes one or other would be in favour with the government. But Christianity was regarded with more suspicion than its rivals because, like the Jews, its adherents would not perform acts of worship to the God Cæsar. This made it a seditious religion, quite apart from the revolutionary spirit of the teachings of Jesus himself. MOSAIC OF SS. PETER AND PAUL POINTING TO A THRONE, ON GOLD BACKGROUND MOSAIC OF SS.
