If something is commanded in the Bible, the command must surely be obeyed if we are to be true to the Bible. This is what many people think, especially when they hear representatives of churches today arguing about moral issues. In fact, the matter is not as simple as this, and at various periods of history, churches have had quite differing views on how biblical commandments should be understood, and on whether they can be applied to their situations, if at all. The book falls into two sections. The first sketches the history of the use of the Bible in social, moral and political questions from the use of the Old Testament in the New Testament, to the present day. The second part looks at some case studies, including human and sexual relationships, life issues, attitudes to lawful authority, and the charging of interest.
