Where the individual feels free and responsible for his own fate, or among minorities striving for freedom and independence, humanistic religious experience develops. The history of religion gives ample evidence of this correlation between social structure and kinds of religious experience. Early Christianity was a religion of the poor and downtrodden; the history of religious sects fighting against authoritarian political pressure shows the same principle again and again. Whenever, on the other hand, religion allied itself with secular power, the religion had by necessity become authoritarian. The real fall of man is his alienation from himself, his submission to power, his turning against himself even though under the guise of his worship of God. Indeed, man is dependent; he remains subject to death, old age, illness, and even if he were to control nature and to make it wholly serviceable to him, he and his earth remain tiny specks in the universe. But it is one thing to recognize one's dependence and limitations, and it is something entirely different to indulge in this dependence, to worship the forces on which one depends. To understand realistically and soberly how limited our power is is an essential part of wisdom and of maturity.
