Amid continuing advances in medical research and treatment, Gilbert Meilaender’s Bioethics has long provided thoughtful guidance on many of society’s most difficult moral problems—including abortion, assisted reproduction, genetic experimentation, euthanasia, and much more. In this fourth edition, Meilaender updates much of the data referenced in the book and responds directly to recent developments, such as the CRISPR/Cas9 method of gene editing. Christians seeking discernment in this new decade will appreciate Meilaender’s circumspect writing and his ability to address the nuances of each issue while maintaining strong and clearly stated moral convictions.
