Why I Am Not a Christian ? “I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world. You may think that I am going too far when I say that that is still so. I do not think that I am. You find as you look around the world that every single bit of progress of humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or every mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world.” — Bertrand Russell, Why I Am Not a Christian (1927).
