leaven of intolerance
Note from Of the Liberty of Thought and Discussion by J S Mill

Ample warning may be drawn from the large infusion of the passions of a persecutor, which mingled with the general display of the worst parts of our national character on the occasion of the Sepoy insurrection. The ravings of fanatics or charlatans from the pulpit may be unworthy of notice; but the heads of the Evangelical party have announced as their principle for the government of Hindoos and Mahomedans, that no schools be supported by public money in which the Bible is not taught, and by necessary consequence that no public employment be given to any but real or pretended Christians. An Under-Secretary of State, in a speech delivered to his constituents on the 12th of November, 1857, is reported to have said:

"Toleration of their faith" (the faith of a hundred millions of British subjects), "the superstition which they called religion, by the British Government, had had the effect of retarding the ascendancy of the British name, and preventing the salutary growth of Christianity.... Toleration was the great corner-stone of the religious liberties of this country; but do not let them abuse that precious word toleration.

As he understood it, it meant the complete liberty to all, freedom of worship, among Christians, who worshipped upon the same foundation. It meant toleration of all sects and denominations of Christians who believed in the one mediation. I desire to call attention to the fact, that a man who has been deemed fit to fill a high office in the government of this country, under a liberal Ministry, maintains the doctrine that all who do not believe in the divinity of Christ are beyond the pale of toleration. Who, after this imbecile display, can indulge the illusion that religious persecution has passed away, never to return?
