This study constructs a biblical-theological defense of the sacredness of human life as a cardinal ethical norm in Christian ethics. Grounded primarily in Chapter 8 (“So Much Value: The Sacredness of Life”) of David P. Gushee and Glen H. Stassen’s Kingdom Ethics (2016) and Gushee’s The Sacredness of Human Life (2013), this paper evaluates human worth through the overarching framework of Walter C. Kaiser Jr.’s promise-plan theology.

This study constructs a biblical-theological defense of the sacredness of human life as a cardinal ethical norm in Christian ethics. Grounded primarily in Chapter 8 (“So Much Value: The Sacredness of Life”) of David P. Gushee and Glen H. Stassen's Kingdom Ethics (2016) and Gushee's The Sacredness of Human Life (2013), this paper evaluates human worth through the overarching framework of Walter C. Kaiser Jr.'s promise-plan theology. By examining the Hebraic cognitive environment, ancient Near Eastern cosmic-temple inauguration imagery, and Second Temple horizons, this essay contends that human life possesses an indestructible, ascribed sacredness bestowed by sovereign divine decree rather than contingent functional capacities. The analysis establishes five Christological and incarnational pillars—Jesus's inclusive ministry, the…

Contemporary moral philosophy and Christian bioethics contend with a profound crisis regarding the nature, origin, and boundaries of human worth. Under the pervasive influence of post-Enlightenment utilitarianism and modern biological physicalism, secular ethicists frequently reduce the human person to neurobiological processes, evaluating moral status through exercisable cognitive faculties, economic output, or functional utility. Concurrently, Western Christian theology has often absorbed post-canonical Hellenistic dualisms that bifurcate personhood into a disposable material body and an immortal mind, treating creaturely finitude and physical impairment as accidental defects rather than intrinsic aspects of created reality. When physical weakness, advanced dementia, or embryonic vulnerability are evaluated through these reductionist frameworks, human worth becomes precarious, shifting from an absolute divine endowment…

What This Study Explores

Promise-Plan Theology • Kingdom Ethics

Why is human life sacred in Christian ethics?

Human life is sacred because every person bears God’s image and because the Son assumed human nature, died, and rose bodily for humanity’s redemption. Dignity is therefore given by God; it does not rise or fall with independence, health, cognitive ability, usefulness, or social recognition.

This conviction forms a consistent ethic of protection and neighbor-love across the whole human lifespan. It calls Christians to defend vulnerable persons while also providing the material, relational, and communal care that makes such protection credible.

Key Claims

  • The image of God grounds equal human worth before differences in capacity, status, age, or condition.
  • The incarnation affirms embodied human nature rather than treating bodies as disposable containers.
  • The resurrection directs Christian hope toward renewed embodied life, not escape from creatureliness.
  • Biblical prohibitions against murder are joined to positive duties of rescue, mercy, justice, and peacemaking.
  • A consistent life ethic addresses abortion, euthanasia, disability, poverty, racism, war, and violence without flattening their distinct moral questions.

Interpretive Context

Appeals to autonomy alone cannot secure the dignity of people whose agency is developing, impaired, or dependent. Christian ethics treats dependence as a normal feature of creaturely life and locates freedom within obligations to God and neighbor.

The promise-plan broadens the command not to kill into God’s purpose to bless the nations and restore creation through Christ. Moral witness is therefore both prohibitive and constructive: the church must become a community in which threatened lives can be welcomed and sustained.
