R.C. Zaehner's The Catholic Church and World Religions examines the official theological position of the Roman Catholic Church on world religions, bridging the gap in the literature by analyzing the teachings of the Second Vatican Council and the post-Conciliar magisterium, and comparing it theologically and phenomenologically with major religions and new religious movements, highlighting both fundamental similarities and fundamental differences between Catholicism and other religions such as Buddhism, Hinduism, and Islam. Overall, this book is a serious theological study of interreligious dialogue from a Catholic perspective, explaining how the Catholic faith interacts with the diversity of world religions and pointing out the elements of fundamental similarity and fundamental differences between these religions and the Catholic faith.
