"The proper office of religion is to regulate the heart of men, humanize their conduct, infuse the spirit of temperance, order, and obedience; and as its operation is silent, and only enforces the motives of morality and justice, it is in danger of being overlooked, and confounded with these other motives."
"The whole of natural theology ... resolves itself into one simple, though somewhat ambiguous proposition, That the cause or causes of order in the universe probably bear some remote analogy to human intelligence."
"That, upon the whole, we may conclude that the Christian religion not only was at first attended with miracles, but even at this day cannot be believed by any reasonable person without one. Mere reason is insufficient to convince us of its veracity: And whoever is moved by Faith to assent to it, is conscious of a continued miracle in his own person, which subverts all the principles of his understanding, and gives him a determination to believe what is most contrary to custom and experience."
"When we run over libraries persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames; for it can contain nothing but sophistry and illusion."
"All the philosophy, therefore, in the world, and all the religion, which is nothing but a species of philosophy, will never be able to carry us beyond the usual course of experience, or give us measures of conduct and behaviour different from those which are furnished by reflections on common life. No new fact can ever be inferred from the religious hypothesis; no event foreseen or foretold; no reward or punishment expected or dreaded, beyond what is already known by practice and observation."
"That the corruption of the best things produces the worst, is grown into a maxim, and is commonly proved, among other instances, by the pernicious effects of superstition and enthusiasm, the corruptions of true religion."
"I shall venture to affirm, that there never was a popular religion, which represented the state of departed souls in such a light, as would render it eligible for human kind, that there should be such a state. These fine models of religion are the mere product of philosophy. For as death lies between the eye and the prospect of futurity, that event is so shocking to nature, that it must throw a gloom on all the regions which lie beyond it; and suggest to the generality of mankind the idea of Cerberus and Furies; devils, and torrents of fire and brimstone."
"What a noble privilege is it of human reason to attain the knowledge of the supreme Being; and, from the visible works of nature, be enabled to infer so sublime a principle as its supreme Creator? But turn the reverse of the medal. Survey most nations and most ages. Examine the religious principles, which have, in fact, prevailed in the world. You will scarcely be persuaded, that they are any thing but sick men's dreams: Or perhaps will regard them more as the playsome whimsies of monkies in human shape, than the serious, positive, dogmatical asseverations of a being, who dignifies himself with the name of rational."
"Deacon King was tried for violating the Sabbath, and so hot was the debate that it was referred to the church council, which ultimately decided, after long and grave debate, that the deacon had committed a 'work of necessity and mercy.'"
"Mead had studied for the ministry, but had lost his faith and took great delight in blasphemy. Capt. Charles H. Frady, pioneer missionary, held a meeting here and brought Mead back into the fold. He then became so devout that, one Sunday, when he happened upon a swimming party, he shot at the people in the river, and threatened to kill anyone he again caught desecrating the Sabbath."
"Adjoining a refreshment stand ... is a small frame ice house ... with a whitewashed advertisement on its brown front stating, simply, "Ice. Glory to Jesus." The proprietor of the establishment is a religious man who has seized the opportunity to broadcast his business and his faith at the same time."
"When the Revolutionaries ran short of gun wadding the Rev. James Caldwell ... broke open the church doors and seized an armful of Watts' hymnbooks. The preacher threw them to the soldiers and shouted, "Give 'em Watts, boys--give 'em Watts!"
"[T]he Congregational minister in a neighboring town definitely stated that 'the same spirit which drove the herd of swine into the sea drove the Baptists into the water, and that they were hurried along by the devil until the rite was performed.'"
"Our knowledge of the historical worth of certain religious doctrines increases our respect for them, but does not invalidate our proposal that they should cease to be put forward as the reasons for the precepts of civilization. On the contrary! Those historical residues have helped us to view religious teachings, as it were, as neurotic relics, and we may now argue that the time has probably come, as it does in an analytic treatment, for replacing the effects of repression by the results of the rational operation of the intellect."
"Culture's essential service to a religion is to destroy intellectual idolatry, the recurrent tendency in religion to replace the object of its worship with its present understanding and forms of approach to that object."
