In a world where religion refuses to expire, two responses predominate. The first, to retrench within the certainties of one's native or adopted faith, questioning nothing; the second, to sneer and snarl from the secular side-lines. Here, Stephen Cherry offers a third alternative for religious believer, agnostic, and atheist alike - to engage with the study of theology. Confessing himself to be a reluctant theologian, Cherry puts forward three positive reasons why more people should take theology seriously - because it's fascinating, fun and important. He suggests that genuine theology is the antidote to fundamentalism, contrasts the theological approaches of Jesus of Nazareth and Richard Dawkins, introduces some of the biggest puzzles unravelled by theology, and reviews the history of the subject in fewer than 20 tweets.
