Applied to: Sanctity of innocent life
Genesis 1:27 establishes the foundational doctrine that human beings are made in the image of God. This is not a peripheral observation. It is the single most important statement in Scripture about the nature and dignity of man, and it governs every question about the sanctity of human life.
“So God created man in his own image, in the image of God created he him; male and female created he them.” (Genesis 1:27)
Genesis 1:27 is the climax of the creation account. God made light, sky, land, vegetation, sea creatures, birds, and beasts—but only man is said to be created in God’s own image (tselem) and likeness (demuth, v. 26). The threefold repetition—“created,” “image of God,” “male and female”—emphasizes the weight of this act. Man is not one creature among many. Man is uniquely stamped with the likeness of God Himself.
The Westminster Larger Catechism (Q. 17) teaches that God created man “male and female, after his own image, in knowledge, righteousness, and holiness, with dominion over the creatures.” The imago Dei is not merely structural (having reason or will). It is moral, relational, and representative. Man images God by bearing His likeness in a way no other creature does.
Importantly, this image is given to man as man—not conditionally, not at a certain stage of development, but by virtue of being human. The text draws no line between categories of human beings who bear the image and those who do not.
Because every human being bears the image of God, human life has a dignity that is intrinsic, not assigned. It does not depend on utility, capability, desiredness, or stage of development. It depends on what man is—a creature made in God’s likeness.
This principle is not left merely implicit. Scripture draws it out explicitly in Genesis 9:6:
“Whoso sheddeth man’s blood, by man shall his blood be shed: for in the image of God made he man.” (Genesis 9:6)
Here God Himself gives the reason why the unjust taking of human life is a capital offense: it is an assault on the image-bearer of God. The imago Dei is the doctrinal ground for the prohibition of murder.
The image of God as the basis for the sanctity of life is not confined to Genesis. James 3:9 warns against cursing men “which are made after the similitude of God.” Psalm 8:5 declares that God made man “a little lower than the angels, and hast crowned him with glory and honour.” The entire sixth commandment tradition, as unpacked in the Westminster Larger Catechism (QQ. 135–136), rests on this foundation: because man bears God’s image, the preservation of life—our own and our neighbor’s—is a moral duty.
The Catechism identifies as sins against the sixth commandment not only direct killing, but “all taking away the life of ourselves, or of others, except in case of public justice, lawful war, or necessary defence” and “neglecting or withdrawing the lawful and necessary means of preservation of life” (WLC 136).
If human beings bear the image of God by nature—not by achievement, viability, or social recognition—then the deliberate destruction of innocent human life at any stage is an assault on the divine image. The unborn child is not a potential human being awaiting personhood. The unborn child is a human being, conceived in the image of God, as Psalm 139:13–16 and Jeremiah 1:5 make plain.
Genesis 1:27 does not use the word “abortion.” It does not need to. It establishes the premise from which the conclusion follows by good and necessary consequence: if all human beings bear the image of God, then intentionally destroying an innocent human life is an offense against God’s image.
Applied to civil governance, Genesis 1:27 supports the expectation that:
The Reformed tradition has consistently taught that the civil magistrate’s authority to punish murder (Genesis 9:5–6, Romans 13:4) rests on the same imago Dei doctrine. If the magistrate may punish the taking of life because man bears God’s image, the magistrate may not authorize or fund the deliberate taking of innocent life for the same reason.
Genesis 1:27 does not by itself settle every contested question about when life begins in the biological sense. What it settles is the moral status of human life as such: wherever you have a living human being, you have an image-bearer of God whose life may not be unjustly taken.
This text does not address hard cases involving genuine threats to the life of the mother, ectopic pregnancy, or other medical emergencies where two lives are in conflict. Those require additional careful ethical reasoning. What it does establish is that the default posture toward innocent human life must be protection, not destruction.
It also does not justify treating the sanctity of life as a partisan slogan detached from the broader sixth-commandment ethic, which also requires care for the poor, the sick, the endangered, and the vulnerable after birth.
Genesis 1:27 teaches that every human being is made in the image of God. That image is the doctrinal foundation for the sanctity of human life. In context, and reinforced across the canon, it supports the principle that the deliberate destruction of innocent human life is a grave moral evil—and that civil rulers have a duty to protect, not authorize, the taking of such life. This is a direct teaching of Scripture, not merely a prudential application.
