The book adopts a comparative approach, analyzing legal principles across diverse faiths like Judaism, Christianity, and Islam, and tracing their development from early scriptures to codified systems. It demonstrates how these laws, beyond their spiritual context, have significantly impacted the development of legal and ethical principles worldwide.
Structured in three parts, the book first introduces the concept of religious law, then examines specific examples from major world religions, and finally analyzes their intersection with modern legal systems and ethical debates.
