Book excerpt: Through his desire to obey God at all costs, even if it meant sacrificing his son, Abraham became the definitive model of faith for the major world religions of Judaism, Christianity, and Islam. In this bold look at the legacy of this story, Carol Delaney explores how the sacrifice rather than the protection of children became the focus of faith. Her strikingly original analysis also offers a new perspective on what unites and divides the peoples of the sibling religions derived from Abraham and, implicitly, a way to overcome the increasing violence among them.
