In this new book, renowned theologian Keith Ward offers an original and comprehensive survey of the great diversity of Christian thinking in the modern world. He presents three differing interpretations for over 15 key Christian doctrines, including original sin, the Trinity and eternal life. The result is an introduction not only to Christian beliefs themselves, but also to the similarities and differences in perspective that characterise this global faith. Blending information with theological arguments, this book, also features consideration of major topics such as the contribution made by Christianity to science, culture and ethics, and its role among the other world religions. It should challenge Christians, students and anyone interested in the contemporary spiritual landscape to think creatively about a tradition whose impact has been felt in the most remote areas of the planet.
