Applied to: Sanctity of innocent life
Genesis 9:6 is the first explicit civil-justice ordinance in Scripture concerning the shedding of human blood. It ties the prohibition of murder directly to the imago Dei and establishes the principle that the magistrate bears responsibility for protecting innocent life.
“Whoso sheddeth man’s blood, by man shall his blood be shed: for in the image of God made he man.” (Genesis 9:6)
This verse comes in the Noahic covenant, given after the flood to Noah and his sons as the surviving representatives of the human race. The context is Genesis 9:1–7, where God reaffirms the creation mandate (“Be fruitful, and multiply,” v. 1), grants permission to eat animal flesh (v. 3), forbids eating blood (v. 4), and then solemnly commands that the shedding of human blood will be answered with justice (vv. 5–6).
The Noahic covenant is universal. It is not given to Israel alone. It is given to all of Noah’s descendants—that is, to the entire human race. The Reformed tradition has consistently treated it as a foundational ordinance of common grace, establishing baseline moral order for all nations and all civil governments.
The phrase “by man shall his blood be shed” is not merely a prediction. It is an ordinance: God delegates to human agents—civil authority—the responsibility of rendering justice when innocent blood is shed. The Westminster Confession of Faith (WCF 23.1) affirms that God has “ordained civil magistrates, to be, under Him, over the people, for His own glory, and the public good.” The Noahic ordinance is one of the earliest expressions of that delegated authority.
“Sheddeth man’s blood” (shophekh dam ha’adam): This refers to the violent, unjust taking of human life. “Shedding blood” in Hebrew is a solemn idiom for killing, especially unjust killing. The construction is emphatic: whoever sheds the blood of the man (ha’adam)—that is, of any human being—by man shall his blood be shed.
“For in the image of God made he man”: This is the stated reason. The prohibition is not grounded in social contract, sentiment, or utility. It is grounded in what man is: an image-bearer of the Creator. This directly recalls Genesis 1:27 and anchors the sanctity of life in creation theology, not cultural convention.
The principle is twofold:
The Westminster Larger Catechism (Q. 135) identifies among the duties required by the sixth commandment: “all careful studies, and lawful endeavours, to preserve the life of ourselves and others.” The magistrate’s duty under Genesis 9:6 is not merely reactive (punishing murder after the fact) but protective (ordering society so that innocent life is safeguarded).
Genesis 9:6 speaks to the abortion question at two levels:
First, it establishes that the unjust killing of a human being is a capital offense against God’s image. If the unborn child is a human being—and Scripture consistently treats the unborn as persons (Psalm 139:13–16, Jeremiah 1:5, Luke 1:41–44)—then the deliberate destruction of the unborn falls under the same moral prohibition.
Second, it establishes that civil authority has an obligation to act. The ordinance is not addressed to private individuals alone. It delegates justice to “man” corporately—to human government. A civil order that not only permits but funds and protects the deliberate killing of innocent human beings is in direct contradiction to the Noahic ordinance.
This is not a prudential application. It is a direct consequence of the text: if the unborn are human, and if the shedding of innocent human blood is an offense God commands civil authority to answer, then civil complicity in abortion is a violation of Genesis 9:6.
Genesis 9:6 does not settle every question about appropriate penalties, legal frameworks, or how to handle complex medical situations. It establishes the principle that innocent human life must be protected by civil order and that its deliberate destruction is an offense against God.
It also does not teach that every death is murder. Just war, lawful execution, and genuine self-defense are recognized in the Reformed tradition as exceptions where the taking of life is not unjust (WLC 136). The key qualifier is innocent life: the unborn child has committed no crime and poses no threat.
Nor does this text authorize vigilante justice or extralegal violence. The ordinance delegates justice to constituted authority—“by man”—not to private vengeance.
For the citizen: Genesis 9:6 teaches that the sanctity of human life is a creational ordinance, not a sectarian preference. Christians should advocate for civil protection of innocent life as a matter of justice, not merely personal conviction.
For the magistrate: The civil ruler is placed under a divine obligation to protect innocent human life. A magistrate who authorizes, funds, or defends the deliberate destruction of the innocent is acting contrary to the ordinance God established for all human government in the Noahic covenant.
Genesis 9:6 is God’s foundational ordinance for the civil protection of human life. It grounds the prohibition of murder in the imago Dei and delegates justice to human authority. Applied to the question of innocent life, it teaches that civil government may not treat any class of image-bearers as disposable. This is a direct teaching with universal scope—not a prudential inference, but a creation-order obligation binding on all nations and all magistrates.
