Religion is among the oldest and most universal of human institutions, and the classical sociologists treated it not as a matter of private faith but as a social force with observable consequences. The three founding traditions — functionalist, Weberian and Marxist — each ask a different question. The functionalists ask what religion does for society, Weber asks how religious ideas shape economic and social action, and Marx asks whose interests religion ultimately serves. Together they supply the analytical backbone for almost every question on this part of the syllabus.

The functionalist theory

The functionalist account is associated above all with Émile Durkheim, whose The Elementary Forms of Religious Life (1912) sought the essence of religion by studying totemism among Australian Aboriginal clans. Durkheim argued that all religions divide the world into two categories — the sacred and the profane. The sacred consists of things set apart and forbidden, surrounded by ritual and awe; the profane is the ordinary, everyday world. What people worship, he claimed, is ultimately society itself, represented through the totem.

For Durkheim religion is a social fact — external to the individual and exercising constraint. Its key functions are:

  • Social solidarity — collective worship reaffirms shared values and binds members into a moral community or church.
  • Collective conscience — ritual generates collective effervescence, an emotional energy that renews commitment to the group.
  • Socialisation and control — religious norms discipline conduct and give social rules a sacred authority.

Later functionalists such as Malinowski stressed religion's role in managing anxiety at moments of crisis — birth, death, harvest — while Parsons emphasised how it provides ultimate meaning and legitimates the value system. The recurring critique is that functionalism neglects religion's capacity to divide rather than unite, as sectarian conflict repeatedly shows.

The Weberian theory

Where Durkheim looked at religion's integrative function, Max Weber examined its power to change society. In The Protestant Ethic and the Spirit of Capitalism (1905) he argued that Calvinist theology — especially the doctrine of predestination — produced a distinctive psychological orientation. Unable to know whether they were among the saved, believers sought reassurance in disciplined work, methodical self-denial and worldly success as signs of grace.

This Protestant ethic — a set of ascetic values — unintentionally supplied the spirit of capitalism: the reinvestment of profit, rational calculation and treating labour as a moral duty. Weber's central claims are worth memorising:

  1. Ideas, not merely economic conditions, can be an independent cause of social change.
  2. The link between ethic and capitalism was one of elective affinity, not simple causation.
  3. His wider studies of Hinduism, Confucianism and Judaism showed why comparable rational capitalism did not emerge elsewhere.

Weber thus offered a direct counter to economic determinism, though critics note that capitalism preceded Calvinism in some Catholic regions.

The Marxist theory

For Karl Marx, religion belongs to the superstructure and reflects the material conditions of a class society. His famous phrase describes religion as the opium of the people — both a genuine expression of suffering and a sedative that dulls it. Religion, in this view:

  • Legitimates inequality by presenting the social order as divinely ordained.
  • Provides ideological control, promising rewards in an afterlife and so deferring demands for change on earth.
  • Produces false consciousness, masking the true source of exploitation.

Marx expected religion to wither once class exploitation ended. Neo-Marxists such as Gramsci qualified this, noting that religion can also inspire resistance — as in liberation theology — so its role is more contradictory than the base–superstructure model suggests.

How to use this in the exam

Treat these three theories as a toolkit rather than rival dogmas. A strong answer sets Durkheim's emphasis on solidarity against Marx's emphasis on control, then uses Weber to show that religion is neither purely integrative nor purely oppressive but can drive change. Always name the key texts and dates, deploy the paired concepts — sacred and profane, elective affinity, false consciousness — and close with a critique, for instance that all three were framed before secularisation and religious revivalism complicated the picture. Illustrations from Indian society, such as caste legitimation or reformist movements, will lift a competent answer into the top band.
