Seven Heretical Sermons is a collection of essays in sermon form intended for the layperson dealing with the impact of modern science on theology. Written with a humorous, sometimes sarcastic tone, it reviews the historical development of several theological ideas, including aspects of beliefs about abortion, the origin of religion, homosexuality, evil, creation, and the nature of God; all in the context of modern scientific thought. In the past, when science has appeared to contradict theology, it has been theology that eventually adapted to science. Today that process continues, despite many efforts to resist the process. Here physics and anthropology are mixed with history and textual analysis to explore a new way of looking at religion.
