A believer is a bird in a cage, a Freethinker is an eagle parting the clouds with tireless wing. At present, owing to the inroads that have been made by liberals and infidels, most of the churches pretend to be in favor of religious liberty. Of these churches we will ask this question: How can a man, who conscientiously believes in religious liberty, worship a God who does not? They say to us: We will not imprison you on account of your belief, but our God will. We will not burn you because you throw away the sacred Scriptures, but their author will. We think it an infamous crime to persecute our brethren for opinion’s sake, — but the God, whom we ignorantly worship, will on that account, damn his own children forever.
Robert Green Ingersoll – “Individuality” (1873)
