Christian Responses to Scientific Issues (AQA A-Level Religious Studies): Revision Notes
Christian Responses to Scientific Issues
Christianity and science
Christianity can be compatible with science when both are understood as different ways of understanding reality. Many rational Christians, such as John Polkinghorne, view Christianity and science as complementary rather than contradictory approaches to truth. Those who completely reject science as unchristian, or Christianity as unscientific, miss this important distinction.
Belief in Christian doctrines, such as the resurrection of Jesus, remains a matter of faith rather than scientific hypothesis. Christianity does not claim to establish scientific proof for its beliefs, but neither does it necessarily conflict with scientific understanding.
Science, morality and religion
The nature of science and religion
Science involves the systematic application of reason and evidence, along with the evaluation and refinement of theories. It is morally neutral in itself. Religion, by contrast, concerns itself with moral questions. Religious people can reasonably comment on the ethical implications of scientific developments and technology.
Ethical challenges from science
Science and technology raise ethical questions without easy answers. Because science has contributed greatly to human wellbeing historically, many assume it will continue doing so. Where clear harm cannot be demonstrated, people often adopt a utilitarian approach, seeking the greatest benefit for the greatest number. For instance, manipulating DNA in human embryos may be considered acceptable if it could benefit many people.
Common Mistake to Avoid:
Just because something is scientifically possible does not mean it should be done. Science alone cannot provide moral guidelines for research or technology.
Religion and moral guidelines
Religion does not hold a monopoly on moral thinking, which can also be approached from entirely secular perspectives. However, science alone cannot provide moral guidelines for research or technology.
Christianity offers general moral principles, but these must be applied through reason to modern scientific issues. Dame Mary Warnock argued that whilst Christians may make personal ethical decisions based on their faith, they can only extend such decisions to wider society if they can justify them using reason and experience available to everyone, religious or not.
Genetic engineering: an overview
Key definitions
Genetic engineering refers to the attempt to engineer a unique set of genes for genetic modification of humans, animals and plants. It has potential to cure conditions such as cystic fibrosis and Down's syndrome, produce children with enhanced physical and mental characteristics, and create transhumans.
The Human Genome Project aims to map all human chromosomes to identify and isolate genes responsible for various conditions, including cystic fibrosis and Down's syndrome.
Transhumans are humans who would be genetically engineered to possess advanced intellectual, physical and psychological powers when the technology develops sufficiently.
Therapeutic genetic engineering involves genetic engineering intended to repair genes to correct or eliminate conditions.
Important distinctions
Key Difference: Genetic Engineering vs Cloning
Genetic engineering differs from cloning in fundamental ways:
- Cloning produces exact copies of an organism with genes copied within the same species
- Genetic engineering aims to create unique sets of genes and can exchange genes between different species
The process uses enzymes to extract DNA pieces from one organism and insert them into gaps in another organism's DNA, creating a genetically modified organism.
Current and potential applications
Current uses include:
- GM crops modified to resist disease and insect attack, producing higher yields
- Production of bacteria that make insulin rapidly for diabetes treatment
- Various medical applications
Potential future applications include:
- Treating conditions such as cystic fibrosis, Alzheimer's and Down's syndrome
- Engineering children with particular characteristics like enhanced intelligence or appearance
- Creating transhumans with advanced abilities for hostile environments or enhanced weapons systems
The Oncomouse example
Oncomouse was a genetically modified mouse carrying an activated oncogene (a gene with potential to cause cancer) for oncology research purposes. For some, this technology crosses moral boundaries, particularly regarding interference with the proper nature of animals.
Christian principles on genetic engineering
Foundational Christian views
Christians generally agree that human life is a gift from God. This foundational belief leads to different perspectives on genetic engineering:
Conservative view:
Any attempt at genetic engineering manipulates life so it differs from God's intention. This may contradict God's will for the person and represents humans attempting to assume powers that belong rightly to God.
Progressive view:
Science and reason are God-given abilities. Respect for life should lead Christians to use these abilities to benefit life as much as possible. God would not have given humans capacity for successful genetic engineering if He did not intend them to use it.
Catholic Church responses
The Catholic Church has approached genetic engineering cautiously. The science remains in its infancy, and ethical issues lack clarity because all risks are not yet known.
GM crops
The Church gives qualified approval, primarily because GM crops offer one means of feeding the poor. Given widespread malnutrition globally, this weighs heavily in Catholic thinking.
GM animals
The Catholic approach is more guarded. Some Catholic voices argue that according to natural moral law, altering animals' genetic code prevents them fulfilling their final end. Since God gave animals their genetic structure, it is not clear that animals like pigs should be engineered to provide compatible human body parts.
Therapeutic genetic engineering
The Catholic Church generally approves therapeutic genetic engineering with potential to cure conditions like Alzheimer's, Parkinson's, cystic fibrosis and muscular dystrophy.
Germline therapy
Catholic Caution on Germline Therapy:
The Church is generally hesitant about germline therapy, where healthy genes are introduced into germ cells (sperm, egg, zygotes) to correct gene-variants that pass down through generations.
This caution stems from:
- Many practical difficulties
- Concerns that unforeseen or unforeseeable bad effects will affect children
- The permanent nature of changes affecting future generations
Enhancement therapy and transhumanism
The Catholic Church rejects enhancement therapy, where new technologies improve human specification. Within approximately 25 years, intelligence might be increased exponentially, and humans could be modified for extraordinary physical and psychological strength. The Church opposes this because humanity would no longer reflect God's image.
Protestant Church responses
Given their diversity, Protestant Churches show a wider range of reactions, though main concerns echo Catholic positions. They give qualified approval to genetic engineering of crops and animals, to therapeutic engineering for curing diseases, whilst being more cautious about germline therapy.
More permissive Protestant views
Some Protestants argue that all human potential comes from God as Creator. If new technologies develop with potential to improve life for plants, animals and humans, they should be embraced where risks are justified.
This can extend to enhancement therapy. Joseph Fletcher, in Christian Situation Ethics, suggested Christians should not rule out any procedure based on existing rules or doctrines. Humans are naturally selectors and designers, so if adequate controls exist, there is no reason humans should not be redesigned to improve the species.
Fletcher did not advocate unrestricted genetic modification. Rather, he argued Christian ethics should not be constrained by ruling out procedures because they are allegedly unbiblical.
Seventh-Day Adventist position
Some Christian Churches have clearer policies. In 1995, the Seventh-Day Adventist Church produced an official statement, 'Christian Principles for Genetic Interventions'.
The document emphasises that Christians have great power from God, which brings responsibility since humans are accountable to God for their actions. It identifies four areas of ethical concern:
Four Key Areas of Ethical Concern:
1. The sanctity of human life: If genetic procedures reduce human meaning to mechanistic biological workings, serious potential exists for devaluing human life.
2. The protection of human dignity: This includes protecting personal privacy and confidentiality, since knowledge of genetic profiles could be valuable to employers, insurance companies and relatives.
3. The acceptance of social responsibilities: Questions include whether individuals with genetic disorders should be allowed to procreate freely, and how benefits and burdens of genetic intervention will be shared between rich and poor in society.
4. The stewardship of God's creation: What limits to genetic change should exist? Are there boundaries that should not be crossed when transferring genes between different life forms?
The statement concludes with ten ethical principles Christians should follow for genetic interventions: confidentiality, truthfulness, honouring God's image, preventing suffering, freedom of choice, stewardship of creation, non-violence, fairness, human dignity and healthfulness.
Key ethical considerations
Playing God concerns
Critics worry that genetic engineering represents humans attempting to assume divine powers, manipulating life forms in ways God did not intend. Supporters counter that God-given abilities should be used responsibly to benefit creation.
Human dignity and identity
If genetic modifications fundamentally alter what it means to be human, particularly through creating transhumans, this raises questions about human dignity and whether humans would still reflect God's image.
Justice and access
Social Justice Concerns:
How will benefits and burdens of genetic technology be distributed? Will the rich gain access to enhancements whilst the poor are left behind? This raises significant social justice concerns that Christians must address.
Unintended consequences
The long-term effects of genetic modifications, particularly germline changes that pass to future generations, remain unknown. Christians must weigh potential benefits against risks of unforeseen harmful effects.
Exam Tips:
- Understand the distinction between different types of genetic engineering (therapeutic vs enhancement; crops vs animals vs humans)
- Be able to explain why different Christian denominations reach different conclusions on the same issue
- Remember that Christian responses are not strictly denominational but represent different emphases and interpretations of core principles
- Connect genetic engineering issues to broader Christian ethical principles like stewardship, sanctity of life, and human dignity
- Be prepared to evaluate whether Christian principles provide adequate guidance for emerging technologies
Key Points to Remember:
- Science is morally neutral; religion addresses the moral and ethical dimensions of scientific developments
- Christians share common ground in believing human life is a gift from God, but differ on implications for genetic engineering
- The Catholic Church gives qualified approval to therapeutic genetic engineering but rejects enhancement therapy that would alter humanity beyond God's image
- Protestant responses range widely, from cautious acceptance to Fletcher's more permissive situation ethics approach
- Key ethical concerns include the sanctity of life, human dignity, social justice in access to technology, and stewardship of God's creation
