It's no surprise to realise that Christians don't always agree on everything they believe. There has always been a wide variety of expression across the global Church on all sorts of issues and doctrines. But at what point does doctrinal "diversity" become a problem? When does a celebration of varied beliefs become unfaithful to God's Word? Should Christians ever consider leaving their church or denomination, and why? Is there ever a basis on which we should stop working with other Christians? How should Christians think about doctrinal division in light of the Biblical call for church unity? And what are the implications of some of the hot topic issues causing tension across the Church today?
