Christianity, Society and Secularisation

What is the proper relationship between Christianity and the wider society? How should the Church engage with politics? And is religion inevitably declining in the modern world? These questions are central to the study of Christianity at A-Level. This lesson examines the secularisation thesis, the relationship between Christianity and the state, liberation theology, feminist theology, and the complex relationship between Christianity and science.

The Secularisation Thesis

Key Definition: Secularisation is the process by which religion loses its social significance — its influence on politics, culture, education, and daily life. The secularisation thesis holds that modernisation inevitably leads to the decline of religion.

Max Weber (1864–1920)

The German sociologist Max Weber is one of the founding figures of secularisation theory. He argued that modernity involves a process of "disenchantment" (Entzauberung) — the replacement of magical, religious, and mythical explanations of the world with rational, scientific ones.

Weber also argued that, ironically, Christianity itself contributed to secularisation. In The Protestant Ethic and the Spirit of Capitalism (1905), he proposed that Calvinist Protestantism, with its emphasis on hard work, frugality, and worldly success as signs of divine election, helped to create the capitalist mentality — which eventually outgrew its religious origins and became a secular force.

Steve Bruce (b. 1954)

The British sociologist Steve Bruce is the most prominent contemporary defender of the secularisation thesis. In God is Dead: Secularization in the West (2002), he argues that:

• Industrialisation, urbanisation, and rationalisation have undermined the social conditions that sustained religion
• Religious diversity (pluralism) relativises all truth-claims — when there are many religions to choose from, none can claim a monopoly on truth
• The privatisation of religion — religion becomes a matter of personal choice rather than a public, communal reality
• Evidence: church attendance in Britain has declined dramatically (from approximately 40% of the population in 1851 to under 5% in the 2020s)

Criticisms of the Secularisation Thesis

Criticism	Key Proponent
The American exception	Peter Berger (1929–2017) initially supported the secularisation thesis but later recanted, noting that the United States is both highly modern and highly religious. "The assumption that we live in a secularised world is false"
Global resurgence of religion	Pentecostalism is the fastest-growing form of Christianity, especially in Africa, Asia, and Latin America; Islam is growing worldwide; Hinduism and Buddhism remain vibrant
Believing without belonging	Grace Davie (b. 1946) argues that in Europe, people have not stopped believing — they have stopped attending church. Religion persists in private belief even as institutional participation declines
Spiritual but not religious	Many people describe themselves as "spiritual but not religious," suggesting a transformation rather than disappearance of the sacred
Rational choice theory	Rodney Stark (1934–2022) argued that religion operates like a market — where there is competition (as in the US), religion thrives; where there is a monopoly (state churches in Europe), it stagnates

Christianity and the State

The relationship between Christianity and political power has varied enormously across history.

Model	Description	Example
Theocracy	The state is governed directly by religious authority or law	Calvin's Geneva (1541–1564); Puritan Massachusetts
Establishment	One church has a formal, legal relationship with the state	The Church of England (the monarch is the Supreme Governor); the Lutheran churches of Scandinavia
Separation	Church and state are constitutionally separated	The United States (First Amendment, 1791); France (laïcité, 1905)
Persecution	The state actively suppresses religion	The Soviet Union; Maoist China

Church and Politics

Christians disagree about the extent to which the Church should engage in politics.

Position	Argument	Example
Political engagement	The Gospel demands action for justice; the Church must speak prophetically against injustice	Liberation theology; Martin Luther King Jr; Archbishop Desmond Tutu (1931–2021)
Political quietism	The Church should focus on spiritual matters and avoid political entanglement	Some Anabaptist traditions; pietism
Critical distance	The Church should engage with political questions but never identify itself with any political party or ideology	Reinhold Niebuhr (1892–1971); Pope Benedict XVI

Liberation Theology

Liberation theology emerged in Latin America in the 1960s and 1970s as a response to widespread poverty and political oppression. Its central claim is that God has a preferential option for the poor and that theology must begin with the experience of the oppressed.

Key figures:

• Gustavo Gutiérrez (1928–2024): A Theology of Liberation (1971) — the founding text
• Leonardo Boff (b. 1938): a Brazilian theologian who challenged the institutional Church and was silenced by the Vatican
• Óscar Romero (1917–1980): Archbishop of San Salvador, assassinated while celebrating Mass for his defence of the poor; canonised in 2018
