Atheism and Salvation is an original and unique work that explores in detail Karl Rahner's understanding of atheism within the context of anonymous Christianity. In light of Vatican II, Rahner contends that atheism cannot simply be understood as ignorance or willful rebellion against God. Instead, he argues that one can be an atheist on a categorical level and still be a person of supernatural faith and a Christian, albeit in an implicit or anonymous way. In addition to masterfully explaining anonymous Christianity and modern atheism, Atheism and Salvation provides a succinct summary of the traditional proofs for the existence of God. Intended for those who have an interest in the future of theology, religion and philosophy, this insightful work will leave its readers seeing reality in a new light.
