Probably no sacred book has been more influential, not
alone upon the religion derived from it, but upon the total culture of the people who embrace the faith, than the Koran.
Alone among the
religions of the world, Judaism and Christianity place so high a valuation
upon religious liberty because of their own doctrine that the relation God seeks with humans is friendship.
In the end, as may well be imagined, this luxuriant over-emphasis
upon the power of the sacrifice, leading naturally to an exaltation of the power of the priests, who
alone possessed the secrets of their proper performance, were the undoing of Vedic
religion, and it finally disappears.
