Marriage and family: the Christian view
Social ethics begins with the smallest society, the family.
- Marriage in the Christian view: a free, lifelong and faithful promise between a man and a woman, open to children. Catholic teaching calls it a sacrament; many Protestant and Orthodox churches also hold marriage as sacred.
- Family: the "first school" of love, respect, honesty and sharing. It is also the first place where the weak (children, elders, the sick) are cared for.
- Duties: parents care for and teach children; children respect and later care for parents; the whole family shares work.
- Other views: most religions and cultures honour family life, though customs and laws on marriage differ across countries. Respectful discussion and listening are part of social ethics.
Social doctrine: dignity, common good, solidarity, subsidiarity
The social doctrine (social teaching) of the Church is a set of principles used to judge society. They grew from the Bible and from letters by popes since 1891 (Rerum Novarum). Their main principles are:
- Dignity of the person: every human has equal, God-given worth, whatever their age, skill, health or wealth.
- Common good: the conditions (clean water, schools, safety, fair work) that let everyone and every group flourish.
- Solidarity: a firm choice to care for the good of all, since we are all responsible for each other.
- Subsidiarity: decisions are made at the smallest level that can handle them (family, town, nation); bigger levels help but do not take over.
- Justice and care for the poor: give each their due, work for fair wages, and give special attention to those in need. The goods of the earth are meant for everyone.
- Parallels: the UN Declaration of Human Rights (1948), ubuntu in Africa, and seva (service) and dharma in Indian traditions express similar ideas.
Ethics of technology and development
Technology is any tool that extends what people can do: from a plough to artificial intelligence. It is not good or bad by itself; people choose how to use it.
- Questions to ask: Who gains? Who is hurt? Can the harm be undone? Is the choice fair to all and to future generations?
- Human at the centre: tools should serve people, not the other way round. Work, privacy, health and attention need protecting.
- Examples: AI and jobs, data privacy, medical technology and cost, social media and mental health, energy and climate.
- Integral development: a phrase from Pope Paul VI's letter Populorum Progressio (1967). It means development of the whole person and of all people, not only economic growth.
- Care for nature: the earth is a shared home. Development that wastes it is not true development.
Key formulas and definitions
- Social ethics = how to live together fairly
- Dignity = equal worth of every person
- Common good = conditions in which all can flourish
- Solidarity = firm choice to care for the good of all
- Subsidiarity = decide at the smallest level that can do the job; higher levels help
- Integral development = whole person + every person + care for nature
Worked examples
1. A town must decide who runs the local park. Use subsidiarity to suggest an answer.
The neighbourhood or town council should run it, since it knows the park best. The state may give money or rules, but should not take over unless the town cannot manage.
2. A company launches a facial-recognition app. Apply the three technology questions.
Who gains: the company and users who want convenience. Who is hurt: people whose faces are recorded without consent or who are wrongly identified. Is it fair: only with consent, clear limits and a way to appeal; otherwise privacy and dignity are at risk.
3. How do solidarity and the common good differ?
The common good is a goal: conditions in which everyone can flourish. Solidarity is the attitude and action of caring for that good, especially for the weak.
Common mistakes
- Thinking dignity depends on what a person can do or earn. It belongs to every human equally.
- Thinking subsidiarity means "no government help". It means help that supports, not replaces, smaller groups.
- Thinking development means only higher income. Integral development includes health, learning, fairness and nature.
- Thinking technology is neutral and needs no ethics. The way it is designed and used affects people.
