"‘Hindooism’, the word that came to fill the gap, had originally been coined back in the 1780s. The first man known to have used it was an Evangelical. Charles Grant, a Scot who had served the Company both as a soldier and on its board of trade, had initially felt little sense of Christian mission. He had travelled to India with the goal of getting rich. Accordingly, he had seen no reason to disagree with the settled policy of the Company: that its only business was business. Any attempt to convert Hindus to Christianity would risk the precarious foundations of its rule. Its purpose was the making of money, not the winning of souls. But then had come the great crisis in Grant’s life. Gambling debts had threatened his finances. Two of his children had died of smallpox within ten days of each other. Grant, in the depths of his agony, had found himself redeemed by grace. From that moment on, the great object of his life had been to win the Hindus for Christ. Convinced that they were lost in ignorance, he had pledged himself to saving them from all their idolatries and superstitions. These were what he had meant by ‘Hindooism’."
