This is the third installment in a Christian Bioethics series that gathers leading voices in Christian bioethics to examine the themes and issues they find most pressing. The papers address fundamental theoretical questions about the nature of Christian bioethics itself, long-standing ethical issues that remain significant today, including physician-assisted suicide, euthanasia, the definition of death, the allocation of scarce resources, and finally, more futuristic questions regarding transhumanism. The contributions underscore the enduring significance of Christian engagement in bioethics.
