In April 2011, Dr. H. Tristram Engelhardt, Jr. (Prof. Emeritus, Baylor College of Medicine/ Prof., Rice University), one of the top bioethicists in the world, spoke at a bioethics conference in Houston, TX. The conference focused on Health Care in a Secular Culture: The Conscience of Physicians & Nurses at Risk. Dr. Engelhardt presented a paper on Orthodox Christian bioethics entitled, "Christian Bioethics in a Post-Christian World: Facing the Challenges." I highly recommend this lecture for those who labor in the healthcare field, students preparing for such work, and others interested in the difference between "traditional Christianity" (i.e., the Orthodox Christian Way of Life) and secularism.
