Many Christians are concerned about the tide of moral relativism that is rising steadily in our country. And rightly so: Relativism affects our education system, the legal system, and how people think about everyday issues. Yet little has been written on the topic outside academic circles. This void is filled by Frank Beckwith and Greg Koukl, who analyze relativism and present strategies to defend the belief in moral absolutes. Using a commonsense approach, Koukl defines relativism, traces its growth over the past few decades, and critiques the logical inconsistencies to which its supporters are led. He then presents a case for moral objectivism. Beckwith, building on Koukl’s foundation, evaluates the influence of relativism on issues including abortion, homosexuality, political correctness, multiculturalism, and tolerance. In each of these areas, he provides compelling arguments for thinking people. Following in the tradition of C. S. Lewis and Francis Schaeffer, Relativism is an important guide for those who are concerned about intellectual issues that challenge the Christian faith.
