Robert G. Ingersoll said this quote
“ Remembering that only a few years ago men, women, and even children, were imprisoned, tortured and burned, for having expressed in an exceedingly mild and gentle way, the ideas entertained by me, I congratulate myself that calumny is now the pulpit's last resort. The old instruments of torture are kept only to gratify curiosity; the chains are rusting away, and the demolition of time has allowed even the dungeons of the Inquisition to be visited by light. The church, impotent and malicious, regrets, not the abuse, but the loss of her power, and seeks to hold by falsehood what she gained by cruelty and force, by fire and fear. Christianity cannot live in peace with any other form of faith. If that religion be true, there is but one savior, one inspired book, and but one little narrow grass-grown path that leads to heaven. Such a religion is necessarily uncompromising, unreasoning, aggressive and insolent. Christianity has held all other creeds and forms in infinite contempt, divided the world into enemies and friends, and verified the awful declaration of its founder—a declaration that wet with blood the sword he came to bring, and made the horizon of a thousand years lurid with the fagots' flames. ”
