Fully revised and updated, this is a frank critique of Christian belief from a former insider. For almost two decades John Loftus was a devout evangelical Christian, an ordained minister, and an ardent apologist for Christianity. With three degrees - in philosophy, theology, and philosophy of religion - he was adept at using rational argument to defend his faith. But over the years, as he ministered to various congregations and taught at Christian colleges, doubts about the credibility of key Christian tenets began to creep into his thinking. By the late 1990s he experienced a full-blown crisis of faith, brought on by emotional upheavals in his personal life as well as the gathering weight of the doubts he had long harboured. In this honest appraisal of his journey from believer to non-believer, Loftus carefully explains the experiences and the reasoning process that led him to reject religious belief. The bulk of the book is his "cumulative case" against Christianity. Here he lays out the philosophical, scientific, and historical arguments that can be raised against Christian belief. From the implications of religious diversity, the authority of faith vs. reason, and the problem of evil, to the contradictions between the Bible and the scientific worldview, the conflicts between traditional dogma and historical evidence, and much more, Loftus covers a great deal of intellectual terrain. In conclusion, he describes the implications of life without belief in God, some liberating, some sobering.
