“The Christian idea of God as a loving Father is interwoven into the very fabric of our mind and heart; but it was a new idea. To the Jew the basic idea of God was that he was holy in the sense of being different. In no sense did he share our human experience and was in fact incapable of sharing it just because he was God.“It was even more so with the Greeks. The Stoics, the highest Greek thinkers, said the primary attribute of God was apatheia, by which they meant essential inability to feel anything at all. They argued that if a person could feel sorrow or joy it means that some other person was able to influence him. If so, that other person must, at least for that moment, be greater than he. No one, therefore, must be able in any sense to affect God for that would be to make him greater than God; and so God had to be completely beyond all feeling. The other Greek school was the Epicureans. They held that the gods lived in perfect happiness and blessedness. They lived in what they called the intermundia, the spaces between the worlds; and they were not even aware of the world.The Jews had their different God; the Stoics, their feelingless gods; the Epicureans, their completely detached gods. Into that world of thought came the Christian religion with its incredible conception of a God who had deliberately undergone every human experience. Plutarch, one of the most religious of the Greeks, declared that it was blasphemous to involve God in the affairs of this world. Christianity depicted God not so much involved as identified with the suffering of this world. It is almost impossible for us to realize the revolution that Christianity brought about in men’s relationship to God. For century after century they had been confronted with the idea of the untouchable God; and now they discovered one who had gone through all that man must go through.”
