Genetic Engineering and Genesis 1:26-28: Image, Dominion
Short answer: Genesis 1:26-28 says people are made in God's image and given dominion over the earth, which means genetic engineering is neither automatically forbidden nor morally neutral. The passage grants real, delegated authority to cultivate and steward creation, so many forms of genetic research and therapy can be pursued responsibly. But the same passage grounds human dignity in God's image, not in human usefulness or genetic quality, so any use that treats people as products to be designed, ranked, or discarded contradicts the text. Christians should therefore distinguish healing from enhancement, refuse to reduce persons to their genomes, and hold the whole project under God's ownership, since Genesis 1:26-28 makes humans stewards under God and never owners of life itself.
What Genesis 1:26-28 actually grants
The first thing to notice is that dominion is given, not seized. Genesis 1:26 begins with God's own resolve: God said, "Let's make man in our image, after our likeness. Let them have dominion over the fish of the sea, and over the birds of the sky, and over the livestock, and over all the earth, and over every creeping thing that creeps on the earth." The authority comes from above. Humanity does not conquer the world and then claim a mandate; it receives a commission. That single grammatical fact reframes the entire discussion of genetic engineering. Whatever power humans exercise over living things is delegated, accountable, and bounded by the One who delegated it.
Second, the sphere of dominion is broad. Fish, birds, livestock, creeping things, and all the earth are named. The wording is deliberately comprehensive, sweeping across sea, sky, and land. Nothing in the created order is excluded from human care and cultivation. That breadth matters, because it means agriculture, animal breeding, and the study of living things are not intrusions into a sacred zone humans should never touch. From the beginning, humans were meant to work with living creation, to name it, tend it, and cause it to flourish. Genetic engineering, at its most basic level, is a highly sophisticated form of that same tending.
Third, the mandate is tied to blessing and vocation, not to domination for its own sake. In Genesis 1:28, God blesses the man and woman and speaks to them about fruitfulness and filling the earth. The dominion of verse 26 sits inside that blessing. This is royal language, but it is royal service, not royal exploitation. A king in the ancient world was expected to protect and provide for what he ruled. So the question a Christian must ask is not simply whether a genetic technique is possible, but whether it serves the flourishing God intended or corrodes it for the sake of power, profit, or vanity.
Fourth, the passage places a limit that no technology can erase. Humans are made in God's image. That is a status conferred, not achieved. It is not earned by intelligence, strength, beauty, or good genes, and therefore it cannot be lost by disability, disease, or genetic defect. Every person, however conceived or altered, stands inside that dignity. Any use of genetic engineering that quietly assumes some lives are worth less because of their genome has already rejected the foundation of Genesis 1:26-28, no matter how many Bible verses it cites elsewhere.
Image of God before genome
The order in the text is instructive. Image comes before dominion. The man and woman are first image-bearers, and only then are they given rule. If we reverse the order, we get a culture that values people for what they can do rather than for whose they are. Genetic engineering debates often drift into exactly that reversal: what kind of child do we want, what traits are desirable, what conditions should be eliminated from the population. Those questions are not wicked in themselves when aimed at relieving suffering, but they become dangerous when the image of God is treated as an afterthought.
Psalm 139:13-16 supplies the counterweight. It says, "For you formed my inmost being. You knit me together in my mother's womb." The psalmist traces his own existence, in all its particularity, to God's deliberate work. He is not a random assembly of genetic material that happened to turn out reasonably well. He is formed, knit, known. If that is true of every person, then a human being is never merely raw material awaiting improvement. The genome is real, and it matters, but it is not the whole person.
This means Christians can affirm genetic research without adopting a reductionistic anthropology. We can study genes, map them, and seek to correct genuine disorders while insisting that a person is more than a sequence. When a diagnosis is given, the person is not the diagnosis. When a trait is edited, the person is not the trait. The image of God holds steady through every genetic variation, and that steadiness is precisely what protects the weak, the disabled, the unborn, and the inconvenient from being reclassified as mistakes to be engineered away.
It also protects us from the opposite error, a kind of superstitious fear that treats any intervention as rebellion. If God knit us together in the womb, he also gave us minds to understand the body he made. Medicine itself is an intervention. Setting a broken bone, removing a tumor, or providing insulin all involve acting on the body's biology. The image of God does not forbid such action; it directs it toward care. The question is whether our interventions honor the image-bearer in front of us or treat that person as a project to be optimized.
Stewardship, not ownership
Genesis 1:26-28 never uses the language of ownership. Humanity is given dominion; humanity is not given the world as private property to do with as it pleases. The distinction is enormous. A steward manages what belongs to another and answers to the owner. This is why 1 Corinthians 6:19-20 matters so much here: "Or don't you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own." Paul applies the ownership principle to the human body itself. Even our own bodies are not ultimately ours to define or dispose of as we wish.
If the body is not our own, then genetic engineering of the human person cannot be framed as purely private consumer choice, like selecting a phone plan. The stakes are higher than that. We are dealing with temples, with image-bearers, with lives that belong to God. This does not settle every policy question, and faithful Christians will disagree about regulation, research funding, and where exactly to draw lines. But it does rule out the assumption that because I can afford a modification, I have the right to make it without any reference to God, neighbor, or the common good.
Stewardship also implies accountability. A steward who wasted or damaged the estate would be answerable. Applied to genetics, this cuts in both directions. Reckless release of edited organisms, or careless editing of human embryos, is bad stewardship. But so is a timid refusal to use knowledge that could relieve real suffering. The parable logic of Scripture does not reward the servant who buried what he was given out of fear. Wisdom holds both risks together: the risk of playing God, and the risk of neglecting the good we could actually do.
The pastoral result is a posture of humble, watchful obedience rather than either panic or triumphalism. We do not need to pretend genetic technology is neutral, and we do not need to treat it as demonic. We can say plainly: this is power, it is delegated, it is limited, and it will be judged. That posture lets believers engage the field honestly, asking who benefits, who is endangered, who is being treated as less than an image-bearer, and whether the proposed good is real or merely marketed.
Babel, limits, and the dream of total control
Genesis 11:1-9 tells of a humanity that said, "Come, let's build ourselves a city, and a tower whose top reaches to the heavens, and let's make ourselves a name, lest we be scattered abroad on the surface of the whole earth." The problem was not bricks and mortar. The problem was the motive stated in the text: to make a name for themselves and to prevent the scattering God had commanded. Technology became a tool for resisting God's word and securing human autonomy. The tower account is a warning about the spirit that can animate any powerful project, including biotechnology.
That spirit shows up when genetic engineering is marketed as a way to eliminate the human condition itself: aging, suffering, limitation, and finally death. Some of that marketing is sober and some is messianic. When it becomes messianic, it is Babel in a lab coat. The promise of a perfected humanity, freed from the vulnerabilities that God has permitted for now, is a promise no technology can keep and no human should accept uncritically. Romans 8:18-23 is relevant: creation is subjected to futility and groans, and its liberation comes from God, not from our engineering.
Romans 8:18-23 also forbids despair. The creation will be set free into the freedom of the glory of the children of God. Suffering now is not the final word. That means Christians need not grasp at every promised fix as though this life is all there is, and they need not fear that any technology can thwart God's redemption. The resurrection is the guarantee that God's purposes for the body, including the healed and transformed body, will be accomplished by him. Our work is real, but it is penultimate.
Babel ended in confusion and scattering, but even there God's judgment was mixed with mercy. The scattering of Genesis 11 became the setting for the call of Abraham and the blessing of the nations. Similarly, the confusion around genetic ethics need not end in cynicism. It can drive the church back to the text, back to God's character, and back to patient, humble discernment. The lesson of Babel is not that building is wrong; it is that building against God's word collapses, while building under it can be blessed.
Distinguishing healing from enhancement
Most Christian ethical reflection on genetic engineering turns on the line between therapy and enhancement. Therapy aims to restore a function that illness or injury has taken away, or to prevent a severe disorder. Enhancement aims to exceed normal human capacities or to select for traits that are matters of preference rather than health. The line is not always crisp, and honest people will locate it differently in hard cases. But the distinction is not arbitrary, and it does real work in pastoral and policy conversations.
Healing aligns naturally with the dominion mandate understood as care. The God who gave humans authority over creation also gave them compassion and ingenuity to fight disease. Correcting a mutation that causes a devastating disorder looks much more like setting a broken bone than like building a tower to heaven. It honors the image-bearer by seeking their flourishing. This is why many Christians support therapeutic genetic research, including research that may one day treat conditions like sickle cell disease or certain inherited blindness, while still opposing uses that redesign persons according to consumer preference.
Enhancement raises different questions, and the strongest objection is not that it is always harmful in outcome. The objection is about what it does to the human posture. It treats the givenness of life as a defect to be corrected, and it invites parents to love a child conditionally, according to specifications. It also creates a two-tier humanity, where the engineered and the unengineered live under different assumptions about worth. Scripture's anthropology cannot support such a tiering, because the image of God is not distributed according to trait selection.
Even so, humility is required. Some things called enhancement in one generation are called treatment in the next, and some conditions once thought untreatable become ordinary medicine. Faithful Christians may disagree about whether a particular intervention crosses the line, and they should say so without pretending certainty they do not have. What must never be surrendered is the conviction that persons are ends in themselves, loved by God, not specimens to be optimized for someone else's approval.
Deuteronomy's separation laws and the purity of creation
Deuteronomy 22:9-11 forbids sowing a vineyard with two kinds of seed, plowing with an ox and a donkey together, and wearing mixed fabrics. These are Israel's covenant regulations for a particular people in a particular land, and they are not a universal ban on all hybridization or on every mixed-material garment. Applying them directly to modern genetic engineering confuses the Mosaic administration with the present age, and it produces a legalism Scripture itself does not require. Christians are not under the food and fabric laws as a code of righteousness.
That said, dismissing the passage entirely would be careless. These laws taught Israel to honor distinctions God had built into creation and to keep covenant boundaries visible. The underlying instinct, that creation has an order and that humans should not blur everything into everything else, is worth pondering. Genetic engineering can respect the order God made, or it can treat all biological boundaries as arbitrary obstacles to be dissolved. The difference between those two approaches is a real ethical difference, even if Deuteronomy does not settle it for us.
It is also worth noting that the passage addresses seeds, animals, and cloth, not human persons. Extending its logic to say that all genetic modification of humans is sin goes beyond the text. The passage simply does not make that claim. What it does is remind us that God cares about the created order and that human action within it is accountable. That is a legitimate contribution to the discussion, offered at the right weight, not inflated into a proof text.
Wisdom therefore reads Deuteronomy 22:9-11 as one piece of a larger biblical picture, not as the decisive rule. It supports a reverent, non-arbitrary approach to creation. It warns against treating boundaries as meaningless. It does not, by itself, forbid a scientist from editing a gene to stop a fatal disease. Christians who differ on the specifics can still agree that creation belongs to God, that its order is not ours to trample, and that our freedom is bounded by love of God and neighbor.
Pastoral wisdom for a pressured subject
Few topics generate as much heat and as little light as this one. Parents of sick children, researchers, physicians, and pastors all face real decisions, often with incomplete information and competing pressures. What the church can offer is not a list of approved techniques but a way of thinking: God made humans in his image, gave them real authority, called them to humble stewardship, and promised to redeem creation. Within that framework, believers can ask better questions and bear with one another when answers differ. That is not moral laziness; it is the patience Scripture itself models in matters where wisdom is required.
Christians in the field should be encouraged, not suspected. A believer working on gene therapies for children with genetic disease is not sinning by doing careful science; he or she may be exercising dominion in exactly the way Genesis 1:26-28 envisions. What is needed is not withdrawal but presence, with the convictions of the text carried into the lab, the clinic, the ethics board, and the legislature. Salt and light are not metaphors for absence.
At the same time, the church must speak clearly where the text is clear. Every human being, from conception onward, bears God's image and possesses a dignity that no genetic profile can diminish. The unborn are not raw material. The disabled are not defects. The elderly are not burdens. The poor are not test subjects. Where genetic technology threatens any of those truths, the church has a word to say, and it should say it with both conviction and compassion, not with cruelty toward those who disagree.
Finally, the subject drives us back to hope. Romans 8:18-23 promises a creation set free from its bondage to decay into the freedom of the glory of the children of God. Whatever we achieve with our tools, that redemption will be God's gift, not our product. Christians can therefore work hard, engage seriously, and refuse both utopian hype and paralyzed fear, because the outcome of history rests with the One who made us in his image and will not abandon his handiwork.
Biblical fidelity check
Genesis 1:26-28 does establish several things plainly. It establishes that human beings are made in God's image and likeness, that this status is given by God and not achieved, and that humans receive a delegated commission over the living world. It establishes that this commission is part of a blessing, not a curse, and that it is therefore meant for the good of creation. It does not establish a prohibition on genetic engineering, nor does it explicitly mention genes, editing, or biotechnology. It does not tell us which specific techniques are permissible, how regulation should work, or where the therapy-enhancement line falls in every case. Anyone who claims the passage settles those questions is reading more into the text than is there.
A common misreading treats Genesis 1:26-28 as a charter for unlimited human control, as if dominion means the right to do whatever we want with life. That is wrong because the dominion is delegated and accountable, and because the passage's foundation is image-bearing, not ownership. Another common misreading treats the passage as making all human intervention in creation suspect. That is also wrong, because the text commands active, fruitful care of the world, and the same God who made it gave humans the minds to study it. The faithful reading holds both truths: real authority, real limits, real accountability to the God who grants both.

Frequently asked questions
Does Genesis 1:26-28 forbid genetic engineering?
No. The passage gives humans a delegated commission over the living world and grounds human dignity in God's image. It does not mention genetic technology or prohibit it. What it does is set the terms: authority is real but accountable, and people are never mere material to be redesigned. So the passage rules out some uses, especially those that treat persons as products, while leaving many therapeutic possibilities open for wise, case-by-case discernment.
Is editing a human embryo always wrong?
Christians differ, and honesty requires saying so. Many oppose any editing of embryos that destroys them or treats them as research material, on the grounds of image-bearing dignity. Others accept limited editing aimed at preventing severe disease, while rejecting enhancement. The debate turns on what an embryo is, what counts as therapy, and what safeguards exist. Scripture gives first principles, not a technique manual, so careful reasoning and humility are required.
How should Christians think about enhancement versus therapy?
Therapy aims to restore function lost to disease or injury; enhancement aims to exceed normal capacity or select traits by preference. Therapy aligns with compassionate stewardship of creation. Enhancement raises concerns about conditional love, a two-tier humanity, and treating life as a product. The line is not always sharp, and believers may place particular cases differently. What must hold is that every person's worth rests on God's image, not on engineered traits.
