Samuel Clemens, more commonly known by his pen name, Mark Twain was a gifted writer. Yet Twain held a deep contempt for Christianity. He once referred to it as a “slaughterhouse religion” because of the doctrine of the blood atonement, and he often turned his ridicule on those who believed the Bible. He met and fell in love with Olivia Langdon, a young woman from a good Christian family. While they were courting he appeared to have downplayed his lack of faith, and she agreed to marry him.
