The concept of the sanctity of life is one of the most important principles in religious ethics. It underpins Christian and Muslim teachings on abortion, euthanasia, capital punishment, and many other life-and-death issues. This lesson explores what the sanctity of life means and how it applies.
The sanctity of life is the belief that all human life is sacred (holy) because it is created by God/Allah. Life has intrinsic value — it is valuable in itself, not because of what it can do or produce.
"So God created mankind in his own image." (Genesis 1:27)
"Before I formed you in the womb I knew you." (Jeremiah 1:5)
"Do you not know that your bodies are temples of the Holy Spirit?" (1 Corinthians 6:19)
| Issue | Sanctity of Life Teaching |
|---|---|
| Abortion | Taking an innocent life is wrong because all life is sacred from conception |
| Euthanasia | Only God should decide when life ends |
| Suicide | Life is a gift from God; deliberately ending it is wrong |
| Capital punishment | Some Christians oppose it based on the sanctity of life; others support it as biblical justice |
| War | Killing in war may sometimes be necessary but is always regrettable |
"Whoever kills a soul... it is as if he had slain mankind entirely. And whoever saves one — it is as if he had saved mankind entirely." (Surah Al-Ma'idah 5:32)
"And do not kill the soul which Allah has forbidden, except by right." (Surah Al-Isra 17:33)
| Issue | Sanctity of Life Teaching |
|---|---|
| Abortion | Generally haram (forbidden), especially after 120 days (ensoulment), though some exceptions exist |
| Euthanasia | Haram — only Allah decides when life ends |
| Suicide | Strictly forbidden in Islam; life belongs to Allah |
| Capital punishment | Permitted under Shariah for certain crimes, but with strict conditions |

A key debate in medical ethics is whether the quality of life should be considered alongside its sanctity:
| Sanctity of Life | Quality of Life |
|---|---|
| All life is equally valuable regardless of condition | The quality of someone's life matters — severe suffering may reduce quality |
| Life should always be preserved | Sometimes ending suffering may be more compassionate |
| Only God/Allah should decide when life ends | Individuals should have some say in decisions about their own lives |
| Absolute principle — no exceptions | Context-dependent — each case should be judged individually |
Exam Tip: This is a crucial debate. The exam may ask you to evaluate whether the sanctity of life should always take priority over quality of life considerations. Present arguments on BOTH sides.
The sanctity of life connects to human rights:
The sanctity of life is a foundational principle in both Christianity and Islam. It affirms that every human life is sacred, created by God, and of infinite value. This principle shapes religious responses to ethical issues including abortion, euthanasia, and capital punishment. While the sanctity of life provides a powerful framework for protecting human dignity, it also generates difficult debates when it comes into tension with quality of life considerations and individual autonomy.
In 2017 the case of Charlie Gard, an 11-month-old baby with the rare genetic condition MDDS, reached the UK Supreme Court and the European Court of Human Rights. Charlie had severe brain damage and could not see, hear, cry, swallow or move. His parents wanted to take him to the United States for an experimental therapy. Great Ormond Street Hospital argued the treatment had "no prospect of success" and would only prolong his suffering. The courts sided with the hospital. Charlie died in a hospice a week later.
A Catholic theologian would approach this case through the doctrine of ordinary and extraordinary means, articulated by Pope Pius XII in 1957 and affirmed in the 1980 Declaration on Euthanasia. The sanctity of life demands that we never actively kill an innocent person (Exodus 20:13). But it does not require us to use disproportionate means to prolong dying. The theologian would argue that experimental nucleoside therapy, with no evidence of benefit and significant potential to prolong Charlie's suffering, fell outside the duty to preserve life. Pope Francis publicly expressed sympathy with the parents, but the Pontifical Academy for Life affirmed that removing futile treatment is not euthanasia.
