3.2.2 - Sanctity of life
Calling human life sacred sounds clear until an embryo, an unborn child or wartime threat forces competing duties into view. Genesis 1, Psalm 139, the imago Dei and love of neighbour ground Christian protection of life. Their application varies at life's beginning, while just war criteria face an extreme test in nuclear, biological and chemical weapons that threaten civilians and creation alike.
The Concept of Sanctity
In this AQA point, sanctity of life means that life is sacred because it belongs to God. The idea is not just that life is useful, pleasant or socially valuable. It is that life has a holy status before God, so human beings should not treat it as disposable property.
Sanctity of Life
The belief that life is sacred and belongs to God. In Christian ethics this normally means that human life has intrinsic value and must be protected.
The word sanctity comes from the same family of ideas as holy and sacred. To say that human life is sacred is to say that its value is not created by usefulness, intelligence, independence, health, wantedness or social approval. A person does not become valuable only when they can contribute to society.
For many Christians, this belief is grounded in creation. Genesis 1 presents human beings as made in the image of God. Psalm 139 is often used to express God's knowledge and care for a person before birth. The commandment against murder is also relevant, because it treats the intentional taking of innocent human life as a serious moral wrong.
Imago Dei
The belief that human beings are made in the image of God. Christians use this to support the dignity and value of every human person.
However, sanctity of life is not a simple slogan. Christians still have to ask how the principle applies when life is developing, when two lives seem to be in conflict, or when violence is used to prevent a greater evil. That is why AQA links sanctity of life to the embryo, the unborn child, just war theory and weapons of mass destruction.
Sanctity of life gives Christian ethics a strong presumption in favour of protecting life, but the difficult AO2 question is how absolute that presumption should be in complex cases.
Sources and Reasons
Christian arguments for sanctity of life usually combine several sources and beliefs. A strong AO1 answer should not rely on one vague phrase such as "life is special". It should explain why life is sacred in Christian thought.
| Source or belief | AO1 content | How it supports sanctity of life |
|---|---|---|
| Creation by God | God is the creator and giver of life. | Human life is received from God, not owned absolutely by human beings. |
| Imago Dei | Genesis 1:26-27 presents humans as made in God's image. | Human dignity is grounded in relation to God, not in ability or status. |
| Psalm 139 | The psalmist speaks of being known and formed by God before birth. | Many Christians use this to support the value of life in the womb. |
| The commandment against murder | The Decalogue forbids murder. | Innocent human life must not be deliberately destroyed. |
| Love of neighbour | Jesus' teaching centres love of God and neighbour. | Protection of vulnerable life becomes a form of Christian love. |
These sources can be used in different ways. A Roman Catholic, an evangelical Protestant and an Anglican might all appeal to creation and the image of God, but they may reach different conclusions about abortion law, embryo research or military action.
It is also important to avoid a common mistake. Sanctity of life is not identical with quality of life. Quality-of-life reasoning asks about wellbeing, suffering, relationships, capacities and future prospects. Sanctity-of-life reasoning begins from the sacred value of life itself. Some Christians reject quality-of-life arguments when they seem to rank lives as more or less worth protecting. Other Christians think quality of life may still matter when judging tragic medical cases, provided it does not erase the basic value of the person.
| Ethical emphasis | Main question | Possible Christian use |
|---|---|---|
| Sanctity of life | Is this life sacred before God? | Supports strong protection of vulnerable human life. |
| Quality of life | What suffering, flourishing or relationship is possible? | May influence difficult pastoral or medical judgements. |
| Stewardship of life | How should humans care for life entrusted by God? | Emphasises responsibility rather than absolute ownership. |
Christians can agree that life is God-given while disagreeing about whether sanctity of life always rules out ending life in every possible circumstance.
Embryo and Unborn Child
AQA names both the embryo and the unborn child because sanctity of life becomes especially contested at the beginning of human life. In ethical discussion, an embryo usually refers to very early developing human life. The unborn child, or fetus, refers more broadly to life developing in the womb before birth.
Embryo
Early developing human life after fertilisation and before the later fetal stage. Christian ethical debate often asks whether the embryo should be treated as a person, potential person, or human life with special moral status.
Christians who apply sanctity of life strictly often argue like this:
| Step | Reasoning |
|---|---|
| 1 | Human life begins at conception or fertilisation. |
| 2 | Human life is sacred because it is created by God and bears God's image. |
| 3 | The embryo and unborn child are therefore not disposable biological material. |
| 4 | Abortion, destructive embryo research, embryo selection or disposal after IVF are morally very serious, and may be judged wrong. |
This approach is especially clear in Roman Catholic teaching. The Catechism teaches that human life must be respected from conception and that the embryo should be defended in its integrity, cared for and healed as far as possible. Many Orthodox and conservative Protestant Christians reason similarly, even when their church structures and authorities differ.
Other Christians apply sanctity of life in a more graduated or conflict-sensitive way. They may still reject abortion as a casual or merely convenient choice, but they may allow limited exceptions where the mother's life is threatened, where continuing the pregnancy involves grave harm, or where there is a tragic conflict between lives. Some also distinguish between an early embryo and a later unborn child, arguing that moral status develops as pregnancy develops.
The key AQA phrase is different views about its application. The disagreement is not usually about whether human life matters. It is about when full personal rights begin, how to weigh the life and wellbeing of the pregnant woman, whether potential life has the same status as born life, and who has authority to make decisions in tragic cases.
For AO1, explain the application carefully; for AO2, judge whether a Christian view protects vulnerable life without ignoring the mother, medicine and tragic conflict.
Christian Diversity
There is no single Christian institutional answer that covers every denomination in exactly the same way. A careful answer should name diversity without making it sound random.
| Christian view | Typical reasoning | Application to embryo and unborn child | AO2 tension |
|---|---|---|---|
| Roman Catholic | Life is sacred from conception; direct abortion is gravely wrong; embryos must not be used as disposable material. | Strong opposition to direct abortion and destructive embryo research; prenatal care is acceptable when directed to healing. | Clear and consistent protection of unborn life, but critics argue it can be too absolute in tragic cases. |
| Orthodox and many conservative Protestant views | Human life begins at conception and belongs to God; the unborn should be treated as innocent human life. | Strong opposition to abortion and embryo destruction, often with pastoral concern for crisis pregnancy. | Protects the vulnerable, but must explain how compassion works when pregnancy results from trauma or severe medical danger. |
| Church of England | Principled opposition to abortion, while recognising limited cases where abortion may be preferable to available alternatives. | Protects the value of unborn life but allows more room for moral complexity and pastoral judgement. | Avoids simple slogans, but may be criticised as less clear than an absolute position. |
| United Methodist life-based ethics | The unborn life and the pregnant woman are both sacred; tragic conflicts of life with life may occur. | Abortion is not treated as ordinary contraception, but may be legally and morally considered in limited conflicts. | Takes both lives seriously, but leaves difficult judgement about what counts as a genuine conflict. |
| More liberal Christian approaches | Sanctity may be balanced with conscience, compassion, health, autonomy and social context. | May support wider legal access to abortion while still treating the decision as morally serious. | Attends to the mother's agency and context, but may be challenged for weakening protection of unborn life. |
The strongest AO1 makes the difference precise. It is not enough to write "Catholics disagree with Protestants." Some Protestants are more restrictive than some Anglican or Methodist statements, and some Anglicans are personally closer to Catholic teaching than to liberal Protestant ethics. The better contrast is between absolute, limited-exception, gradualist and conscience-based applications of sanctity of life.
This also helps evaluation. A strict conception-based view has the strength of consistency: it prevents the vulnerable from being valued only when wanted or useful. A limited-exception view has the strength of pastoral realism: it recognises that pregnancy can involve danger, coercion, trauma and competing responsibilities. The weakness of the strict view is possible inflexibility. The weakness of the flexible view is that the sacredness of unborn life may become less decisive in practice.
