Book excerpt: Why are human embryos so important to many Christians? What does theology say concerning the moral status of these embryos? Answers to these questions can only be obtained by considering the manner in which Christian theology understands the great theme of the image of God. This book examines the most important aspects in which this image, and the related Christian notion of personhood, can be used in the context of theological arguments relating to the moral status of the human embryo. Thoughtful in approach and ecumenical in perspective, the author combines a thorough knowledge of the science of embryology with a broad knowledge of the theological implications.
