Recent years have witnessed an astonishing cultural and legal shift when it comes to homosexuality and same-sex marriage. Many Christians see these changes as a defeat for Christian values, often painting Christian opponents as sell-outs to secular culture. But can there be a genuinely Christian case for same-sex marriage? This book makes that case. While sensitive to scriptural issues, it focuses on a question that cannot be answered by Scripture alone: What does love for our gay and lesbian neighbors demand? This question calls us to pair theological, philosophical, and scriptural reflection with something else: attention to gay and lesbian lives. We must attend to the psychological research and, more importantly, to the stories our gay and lesbian neighbors tell us about themselves and their experience. Love does not permit us to plug our ears with Bible verses. While this book argues that Christian love calls us to make same-sex marriage available, the deeper conclusion is that Christian values prevail when we wrestle with these questions in a spirit of love: love for those with whom we disagree, and love for those most affected by the decisions we reach.
