Christianity has traditionally claimed to have the unique truth about God. But Christians have been challenged for two thousand years by the existence of genuine devotion, goodness, and insight in other faiths. This book gives a guide to different ways of understanding the relationship between faiths, investigating the origins, strengths, and weaknesses of popular views. It concludes that the best way forward is honestly to admit that no faith has a full understanding of God. Christianity, like other faiths, is a provisional attempt to understand God, and should have the humility to recognise the limitations of its vision.This humility should lead Christians to recognise that other faiths may get things right, and equally that Christianity may get things wrong. Rather than placing their own faith on a unique pedestal, Christians should recognise that all faiths operate on a level playing field, and have much to learn from each other. If believers in different faiths can take this approach to each other, they can move forward together to build understanding, and to resist fundamentalism and religious conflict.
