The book is a study on the recent developments in the field of embryonic stem cell research, that is, the generation and manipulation/exploitation of human embryos for the research and therapeutic purposes and analyzes the issue in the light of the Orthodox theological understanding of human life. The objective of this study is to investigate the ethical problems of embryonic stem cell research from an Orthodox point of view. The book provides not a one side of the flow of argumentation, but shows, how important this issue is and how it can be possibly addressed from the Orthodox perspective.
