From questions about the status of early Christians who renounced their religion under Roman torture, through to current debates about euthanasia, Christianity has always had to grapple with complex moral problems. This book steers readers through these issues, providing a clear and decisive history of the main figures and texts in Christian ethics. Engaging with key figures such as Augustine, Benedict, Aquinas, Luther and Barth, it draws attention to the ways in which particular historical situations have thrown up different ethical dilemmas. Questions arising include human will, the proper form of Christian life, natural law, and whether human nature is at odds with Christian ethics. In conclusion, the author considers the contribution that Christian ethics can make to contemporary moral debates.
