Whoever has an opinion of his own, and honestly expresses it, will be guilty of heresy. Heresy is what the minority believe; it is the name given by the powerful to the doctrine of the weak. This word was born of the hatred, arrogance and cruelty of those who love their enemies, and who, when smitten on one cheek, turn the other. This word was born of intellectual slavery in the feudal ages of thought. It was an epithet used in the place of argument. From the commencement of the Christian era, every art has been exhausted and every conceivable punishment inflicted to force all people to hold the same religious opinions. This effort was born of the idea that a certain belief was necessary to the salvation of the soul.
One great trouble is that most teachers are dishonest. They teach as certainties those things concerning which they entertain doubts. They do not say, "we _think_ this is so," but "we _know_ this is so." They do not appeal to the reason of the pupil, but they command his faith. They keep all doubts to themselves; they do not explain, they assert. All this is infamous.
In all ages reason has been regarded as the enemy of religion. Nothing has been considered so pleasing to the Deity as a total denial of the authority of your own mind. Self-reliance has been thought a deadly sin; and the idea of living and dying without the aid and consolation of superstition has always horrified the Church. By some unaccountable infatuation, belief has been and still is considered of immense importance. All religions have been based upon the idea that God will forever reward the true believer, and eternally damn the man who doubts or denies. Belief is regarded as the one essential thing. To practice justice, to love mercy, is not enough. You must believe in some incomprehensible creed. You must say, "Once one is three, and three times one is one." The man who practiced every virtue, but failed to believe, was execrated. Nothing so outrages the feelings of the Church as a moral unbeliever--nothing so horrible as a charitable Atheist.
One hundred and fifty years ago the foremost preachers would have perished at the stake. A Universalist would have been torn in pieces in England, Scotland, and America. Unitarians would have found themselves in the stocks, pelted by the rabble with dead cats, after which their ears would have been cut off, their tongues bored, and their foreheads branded.
