Developments in Bioethics: CCEA GCSE Religious Studies (Unit 6)
Welcome to your revision notes for Developments in Bioethics! This topic is part of Unit 6: An Introduction to Christian Ethics. Medical technology is advancing faster than ever before. Scientists can now help infertile couples have babies, screen embryos for genetic diseases, and study cells to cure severe illnesses. But just because science can do something, does that mean it should? That is the heart of bioethics. Don't worry if these ideas seem complicated at first—we will break down every concept step-by-step so you feel confident for your exam!
---1. Key Terms and Definitions
Before diving into ethical debates, let's look at the core terms you need to know for the exam:
• Bioethics: The study of ethical, social, and moral issues arising from advances in biology, medicine, and scientific research.
• In Vitro Fertilisation (IVF): A medical procedure where an egg is fertilised by sperm outside the body in a laboratory dish (in vitro means "in glass"). Once fertilised, one or more embryos are placed into the woman's uterus.
• Embryo: An organism in the earliest stages of human development, from fertilisation up to eight weeks.
• Stem Cells: Special "master" cells that are undifferentiated (not yet specialised). They have the unique ability to develop into many different cell types, such as nerve cells or muscle cells.
• Pre-implantation Genetic Diagnosis (PGD): A procedure used alongside IVF to test embryos for specific inherited genetic conditions before they are implanted in the womb.
• Saviour Sibling: A child conceived through IVF and screened using PGD to ensure their tissue or bone marrow is a genetic match to treat a seriously ill older brother or sister.
Memory Tip to Remember IVF vs PGD:
Think of IVF as the method of creation (bringing egg and sperm together in glass) and PGD as the genetic test (checking the embryo before implantation).
Key Takeaway: Bioethics looks at the morality of using modern medical technology on early human life.
---2. Understanding Surrogacy
Surrogacy is an arrangement where a woman (the surrogate) carries a pregnancy and gives birth to a child for another person or couple (the intended parents).
Types of Surrogacy
• Traditional Surrogacy: The surrogate mother's own egg is fertilised by the intended father's (or a donor's) sperm. In this case, the surrogate is the biological and genetic mother of the child.
• Gestational (Host) Surrogacy: An embryo created via IVF using the intended parents' (or donors') egg and sperm is implanted into the surrogate. The surrogate has no genetic connection to the baby she carries.
Key Takeaway: Traditional surrogacy uses the surrogate's own egg, while gestational surrogacy uses IVF so the surrogate has no genetic link to the child.
---3. Embryo Research, Stem Cells, and Cloning
Stem cells offer huge potential for treating degenerative conditions such as Parkinson's disease, Alzheimer's disease, and spinal cord paralysis. However, the way scientists get these cells raises major moral questions.
Embryonic vs Adult Stem Cells
• Embryonic Stem Cells: Taken from human embryos created via IVF that are only a few days old. Harvesting these cells destroys the embryo.
• Adult Stem Cells: Taken from fully developed tissues (like bone marrow). Harvesting adult stem cells does not destroy human embryos.
Therapeutic Cloning vs Reproductive Cloning
It is vital not to mix these two up in your exam:
• Therapeutic Cloning: Creating an embryo to harvest stem cells for medical research and treatments. The embryo is destroyed in the process and is never allowed to develop into a baby.
• Reproductive Cloning: The process of creating a cloned embryo with the deliberate intention of implanting it into a womb to produce a live, genetically identical human baby.
Analogy Time: Think of therapeutic cloning like photocopying a single recipe page to make a medicine, whereas reproductive cloning is like photocopying the entire book to make an identical copy of a person.
Key Takeaway: Therapeutic cloning creates cells to cure diseases, whereas reproductive cloning aims to produce a cloned baby.
---4. UK Law and the HFEA
In the UK, all fertility treatments and human embryo research are strictly regulated by law.
Who is the HFEA?
The Human Fertilisation and Embryology Authority (HFEA) is the UK statutory body that regulates, licenses, and inspects all fertility clinics and human embryo research under the Human Fertilisation and Embryology Act.
Key UK Legal Rules to Remember:
• The 14-Day Rule: Human embryos created outside the body can only be kept alive or researched on for up to 14 days after fertilisation. Why 14 days? This is when the "primitive streak" forms, marking the earliest stage of individual human identity.
• Reproductive Cloning is Banned: Human reproductive cloning is completely illegal in the UK.
• Altruistic Surrogacy Only: Surrogacy is legal in the UK on an altruistic basis (where only reasonable medical/pregnancy expenses are covered). Commercial surrogacy (paying a surrogate a fee for profit or using commercial agencies) is illegal.
Key Takeaway: The HFEA enforces strict UK rules, including the 14-day limit on embryo research and the total ban on human reproductive cloning.
---5. Christian Perspectives on Bioethics
Christians do not all share the same viewpoint on bioethics. In your exam, you will gain high marks by contrasting different Christian traditions.
Core Biblical Principles
• Sanctity of Life: Life is sacred, God-given, and holy.
"So God created mankind in his own image..." (Genesis 1:27 — Imago Dei).
• God Plans Life from the Womb:
"Before I formed you in the womb I knew you..." (Jeremiah 1:5).
"For you created my inmost being; you knit me together in my mother's womb." (Psalm 139:13–16).
• Compassion and Healing (Agape): Jesus spent much of his ministry healing the sick. The command to love one's neighbour (The Golden Rule, Matthew 7:12) leads many Christians to support medical science that relieves human suffering.
1. The Roman Catholic View (Absolute / Natural Law Approach)
The Roman Catholic Church firmly opposes IVF, embryo research, surrogacy, and all forms of human cloning (as stated in papal documents like Donum Vitae and Evangelium Vitae).
• Life begins at conception: The Catholic Church teaches that a human embryo is a human person with a right to life from the moment of fertilisation. Discarding "spare" embryos or destroying them in stem cell research is seen as taking a human life (equivalent to abortion).
• The Purpose of Marriage: Catholic teaching states that sexual intercourse within marriage has two inseparable purposes: unitive (bonding husband and wife) and procreative (creating new life). IVF separates procreation from the loving physical act of marital sex.
• Rejection of Surrogacy & Donors: Surrogacy introduces a third party into the sacred covenant of marriage, which the Catholic Church teaches undermines the family unit.
2. Protestant, Evangelical, and Liberal Christian Views
• Liberal and Mainstream Protestants (e.g., Church of Ireland, Methodist, Church of England):
- Often support IVF for loving couples who cannot naturally conceive, seeing medical science as a God-given tool of healing and compassion.
- Support altruistic surrogacy if done out of love to help a childless couple, provided all parties give informed consent and the child's welfare is protected.
- Often accept adult stem cell research and strictly regulated embryo research (up to the 14-day HFEA limit) if its clear aim is to discover cures for devastating illnesses, applying Jesus' teaching of Agape (selfless love).
• Conservative Evangelicals:
- Strongly emphasize verses like Jeremiah 1:5 and Psalm 139.
- Often share deep concerns about IVF if "spare" embryos are destroyed or frozen indefinitely, maintaining that every embryo is a person known by God.
Key Takeaway: Roman Catholics reject IVF and embryo research because life begins at conception and sex must remain unitive and procreative. Many Protestant and Liberal Christians support IVF and regulated research as acts of Christian compassion and healing.
---6. Common Exam Mistakes to Avoid
• Mistake 1: Saying "All Christians are against IVF."
Correction: While Roman Catholics oppose IVF due to the destruction of spare embryos and the separation of sex from procreation, many Protestant Christians support IVF to help infertile couples.
• Mistake 2: Confusing Therapeutic Cloning with Reproductive Cloning.
Correction: Therapeutic cloning creates stem cells to treat disease and destroys the embryo; reproductive cloning attempts to make a whole baby (and is illegal in the UK).
• Mistake 3: Thinking all surrogacy is illegal in the UK.
Correction: Altruistic surrogacy (paying only reasonable expenses) is legal in the UK. Only commercial surrogacy is banned.
• Mistake 4: Forgetting the 14-day rule.
Correction: Under HFEA regulation, human embryos cannot be researched on or kept alive past 14 days.
7. Quick Review: Topic Summary
• Bioethics: Moral choices regarding medical science and life.
• IVF: Fertilising an egg outside the womb; creates ethical issues over "spare" discarded embryos.
• Surrogacy: Traditional (surrogate's egg) vs Gestational (IVF embryo). Legal in the UK only if altruistic.
• Stem Cells: Master cells used to treat degenerative diseases. Embryonic research destroys embryos; adult stem cell research does not.
• HFEA: Regulates fertility and embryo research in the UK up to a strict 14-day limit.
• Catholic Position: Opposes IVF, surrogacy, and embryo destruction (Sanctity of Life from conception, unitive and procreative marital sex).
• Liberal/Protestant Position: Often supports fertility treatments and regulated research as compassionate healing (Agape love / Golden Rule).
