# Anthropology and Ethics

<!-- type: concept | created: 2026-05-23 | updated: 2026-05-23 -->


## Intro

**What is a human being, and how should a human live?** Those two questions are the heart of this hub. The first is anthropology (what we are). The second is ethics (what we ought to do). Christianity gives connected answers to both, and the answers shape everything else, from how we treat the unborn to how we think about marriage to how we handle suffering.

The Christian answer to "what is a human?" starts in [Genesis 1:27](/codex/genesis-1-27/): humans are made in the image of God. That phrase, the *imago Dei*, is the most important idea in Christian anthropology. Every person, no matter their age, ability, race, or status, carries the image of the Creator. That is the basis for human rights, human dignity, and the conviction that human life is sacred.

Humans are also more than bodies. The Bible treats us as a body and soul together, not a ghost in a machine and not just clever animals. We have minds that think, consciences that judge right and wrong, and the strange experience of being a self. None of those features fit naturally into a world where everything is just particles in motion, which is why human consciousness and morality become real evidence in the case for God.

The Christian answer to "how should a human live?" starts with the two great commands Jesus named: love God with all you have, and love your neighbor as yourself ([Matt 22:37-40](/codex/matthew-22-37-40/)). Every detailed ethical question (about marriage, sex, abortion, slavery in the Bible, divorce, honesty, justice, war) sits underneath those two. Christian ethics is not a rulebook competing with other rulebooks; it is the shape of what love actually looks like for creatures made in God's image.

Christianity also takes seriously that humans are broken. We inherit a bent toward wrongdoing (the doctrine of original sin, sometimes called [concupiscence](/codex/concupiscence/) in the older theological language). That is why ethics cannot be only about effort. Real moral change comes through being remade by Christ, not just trying harder.

The big questions this hub deals with: How do we know right from wrong? Why does the Bible allow some things modern people find disturbing? What makes a person a person? What is marriage? Where does conscience come from? How do Christians answer the charge of being hypocrites?

The rest of this hub maps the core anthropological hubs, the core ethical hubs, the moral arguments for God, and the principal scholarly sources on every question.

## In full

**Layer-1 master hub** for the codex's engagement with **theological anthropology** (what humans are; the *imago Dei*; mind/soul/spirit composition; the body; sexuality; the human relationship to other animals) and **Christian ethics** (the moral law; conscience; moral arguments; bioethics; sexual ethics). The folder holds 12 hubs covering the foundational doctrines + the principal apologetic-deployment points.

The codex's posture: **Christian anthropology is distinctive and non-negotiable**, humans bear the *imago Dei* (image of God), are body-soul unities, are constitutively moral beings, are inheritors of fallen Adamic nature (concupiscence) but redeemable through Christ, and have a unique eschatological destiny (resurrection of the body, eternal communion with God or final judgment). Ethics flows from anthropology, what we are determines what we ought to do.

## Common questions this page answers

**Q: What does it mean to be made in the image of God?**

The *imago Dei* doctrine from [Genesis 1:27](/codex/genesis-1-27/) holds that every human being, regardless of age, ability, race, or status, bears the image of the Creator. That image is the foundation for human rights, human dignity, and the conviction that human life is sacred. See [Imago Dei](/codex/genesis-1-27/) for the full treatment.

**Q: What is Christian anthropology?**

Christian anthropology says humans are body-soul unities made in God's image, constitutively moral, fallen through inherited Adamic nature ([concupiscence](/codex/concupiscence/)), redeemable through Christ, and destined for bodily resurrection. Ethics flows from anthropology: what we are determines what we ought to do.

**Q: How do Christians decide right and wrong?**

The two great commands Jesus named in [Matt 22:37-40](/codex/matthew-22-37-40/) anchor Christian ethics: love God with all you have, and love your neighbor as yourself. Every detailed ethical question on marriage, sex, justice, war, and honesty sits underneath those two. See [Morality](/codex/morality/) for the meta-ethical positions catalog.

**Q: Why does morality point to God?**

Humans have consciences that judge right and wrong, and the experience of moral obligation does not fit naturally into a world of particles in motion. The [moral argument family](/codex/moral-arguments/) holds that objective moral values and duties require a transcendent moral lawgiver. See also [Argument from Conscience](/codex/argument-from-conscience/).

**Q: Are humans just clever animals?**

No; humans have minds, consciences, and the strange experience of being a self, features that resist reduction to physics. See [Mind, Soul, Consciousness](/codex/mind-soul-consciousness/) for the philosophy-of-mind treatment, and [NDEs](/codex/ndes-near-death-experiences/) for near-death-experience research on the survival of consciousness.
