Noted theologian and ethicist Ted Peters accessibly relates the science of stem cells and regenerative medicine in lay terms as he traces the deeply divided ethical debate to three very different moral frameworks and shows the deepest and legitimate concerns of each, including the secular ethical framework employed in most medical ethics. Peters also offers fundamental theological reflection on this great choice, especially insights from theological anthropology. Peters's work is not only a unique guide but also a real model for how honest, religiously informed ethics can be practiced today.
