Current debates in end-of-life ethics exemplify how difficult it can be for Christians to speak into contemporary culture. Yet, some Christians are called specifically to the field of secular bioethics. Dr. Jon Tilburt, a practicing internist and professor of biomedical ethics at Mayo Clinic will explore how working within secular bioethics can be construed as care taking—a form of cultural stewardship. Drawing on examples from end-of-life care and healthcare rationing, he will illustrate challenges and opportunities for a model of cultural engagement within secular bioethics that opens up conversations and hints at realities beyond the imminent.
