At present, a good many men engaged in scientific pursuits, and who have signally failed in gaining recognition among their fellows, are endeavoring to make reputations among the churches by delivering weak and vapid lectures upon the 'harmony of Genesis and Geology.' Like all hypocrites, these men overstate the case to such a degree, and so turn and pervert facts and words that they succeed only in gaining the applause of other hypocrites like themselves. Among the great scientists they are regarded as generals regard sutlers who trade with both armies.Surely the time must come when the wealth of the world will not be wasted in the propagation of ignorant creeds and miraculous mistakes. The time must come when churches and cathedrals will be dedicated to the use of man; when minister and priest will deem the discoveries of the living of more importance than the errors of the dead; when the truths of Nature will outrank the 'sacred' falsehoods of the past, and when a single fact will outweigh all the miracles of Holy Writ.Who can over estimate the progress of the world if all the money wasted in superstition could be used to enlighten, elevate and civilize mankind?When every church becomes a school, every cathedral a university, every clergyman a teacher, and all their hearers brave and honest thinkers, then, and not until then, will the dream of poet, patriot, philanthropist and philosopher, become a real and blessed truth.

~ Robert G. Ingersoll

...I therefore hate the corrupt, slaveholding, women-whipping, cradle-plundering, partial and hypocritical Christianity of the land... I look upon it as the climax of all misnomers, the boldest of all frauds, and the grossest of all libels. Never was there a clearer case of 'stealing the livery of the court of heaven to serve the devil in.' I am filled with unutterable loathing when I contemplate the religious pomp and show, together with the horrible inconsistencies, which every where surround me. We have men-stealers for ministers, women-whippers for missionaries, and cradle-plunderers for church members. The man who wields the blood-clotted cowskin during the week fills the pulpit on Sunday, and claims to be a minister of the meek and lowly Jesus. . . . The slave auctioneer’s bell and the church-going bell chime in with each other, and the bitter cries of the heart-broken slave are drowned in the religious shouts of his pious master. Revivals of religion and revivals in the slave-trade go hand in hand together. The slave prison and the church stand near each other. The clanking of fetters and the rattling of chains in the prison, and the pious psalm and solemn prayer in the church, may be heard at the same time. The dealers in the bodies of men erect their stand in the presence of the pulpit, and they mutually help each other. The dealer gives his blood-stained gold to support the pulpit, and the pulpit, in return, covers his infernal business with the garb of Christianity. Here we have religion and robbery the allies of each other—devils dressed in angels’ robes, and hell presenting the semblance of paradise.
