The splendours of the Parthenon, Colosseum and Great Pyramid of Giza were in stark contrast to the utilitarian conference centre in London’s Docklands, but they were there to make a point.As 4,000 people from dozens of countries filed in for a three-day jamboree of rightwing discourse this week, the images were a reminder that great civilisations of the past had risen, declined and fallen.A commentary warned that western civilisation was at a tipping point, in crisis because it had lost touch with its “Judeo-Christian foundations”.The message greeted those attending a sold-out conference for politicians, policymakers, businesspeople and “culture formers” organised by the Alliance for Responsible Citizenship (Arc) at the ExCeL centre in east London, where non-discounted tickets cost £1,500.The Conservative leader, Kemi Badenoch, and the Reform UK leader, Nigel Farage, addressed the gathering in person.

Mike Johnson, the speaker of the US House of Representatives, and the billionaire entrepreneur Peter Thiel joined via video link from the US,It was not explicitly a faith-based event, but a distinctly religious flavour ran through the proceedings,The Arc’s co-founders and principal faces are Philippa Stroud, a Tory peer and devout Christian, and Jordan Peterson, a Canadian psychologist whose lectures draw heavily on the Bible,Among the group’s known funders is the GB News investor Paul Marshall, a hedge fund boss and media tycoon whose worldview is shaped by his evangelical Christian faith,According to one well-connected former Conservative MP, Marshall’s influence on UK rightwing discourse is growing, not just through GB News but also his ownership of the Spectator magazine and the Unherd website.

Marshall is not a member of any political party and said in a pre-conference interview last week that faith and politics were a “dangerous combination”.But some rightwingers – energised by Donald Trump’s victory and beguiled by the rhetoric of his Catholic vice-president, JD Vance – see populist potential in advocating for “Judeo-Christian values”.The meaning of this phrase, much repeated at the Arc conference, is the “moral foundation of western civilisation” based on the shared values of Christianity and Judaism, according to Dennis Prager, an American conservative talkshow host.He added: “The ultimate embodiment of Judeo-Christian values has been the United States of America.”The term, drawing on both faiths’ biblical roots, was first used in the early 19th century to refer to Jewish converts from Christianity.

Much later, it was adopted by conservative Christians in the US,The former Trump adviser Steve Bannon has fought court battles in an attempt to set up an academy for the Judeo-Christian west – a “gladiator school for culture warriors” – in an Italian monastery,Some believe the phrase has become code for Islamophobia,During Trump’s first term as US president, Meredith Warren of the University of Sheffield said it was a dog-whistle myth peddled by the far right “to draw a line between imagined Christian values and a perceived (but false) threat of Muslim immigration”,Farage, whose populist brand of politics has rarely made reference to the Christian faith, told this week’s conference that Britons should have more children to restore traditional Judeo-Christian culture.

“We’ve kind of forgotten that what underpins everything is our Judeo-Christian culture and that’s where we need to start.And if we recognise that, and if we value that, then I think everything comes from that,” he said.Badenoch did not use the phrase in her speech to the conference but has often described herself as a “cultural Christian”.She understands the “importance of Christian values as the foundation of family and community life”, David Burrowes, a former Tory MP and co-founder of the Conservative Christian Fellowship, said last year.The influence of evangelical Christianity in the Conservative party remains relatively marginal, but it has grown in recent years via two prominent voices: Danny Kruger, an MP since 2019 who has become a leading opponent to legalising assisted dying; and Miriam Cates, who was elected to parliament in 2019 but lost her seat last year, who is a vocal proponent of traditional family values.

Kruger and Cates are on the Arc’s advisory board.Georgina Waylen, a professor of politics at the University of Manchester who has been researching the influence of evangelical Christianity on British politics, said it had “grown in recent years, and most notably in the Conservative party, following the election of a small number of rightwing socially conservative evangelical MPs who were well organised, knew what they wanted to achieve and oppose, and have been aided by the increasing influence of evangelical Christians in the rightwing ecosphere.”She added: “The evangelicals work effectively with others, including some rightwing populists, and have taken advantage of the chaos in the Conservative party.They have been active around gender identity issues and oppose assisted dying.”Evangelical conservative Christian groups have been active in lobbying MPs on issues such as abortion and assisted dying, although their involvement has not always been explicit.

In November, an Observer investigation found that Christian pressure groups were secretly coordinating and funding anti-assisted dying campaigns ostensibly led by grassroots healthcare workers and disabled people.Organisations on the US Christian right have been accused of “infiltrating” the UK, lobbying MPs to restrict women’s reproductive rights.Last year, the UK branch of the US-based Alliance Defending Freedom provided “briefing material and legal analysis” to MPs before a vote on introducing buffer zones to prevent anti-abortion activity outside abortion clinics.One reason for the sometimes covert involvement of such groups is the resistance of many people in a largely secular society to religious individuals or organisations seeking to impose their worldview on others.Evangelical Christians have fared poorly in UK politics whenever their views have come into conflict with principles fundamental to British liberal democracy.

“Religion is much less of a factor in politics here than in the US,” said Nick Spencer of Theos, a Christian thinktank.“But the Christian right is gaining momentum.I don’t think the Arc conference would have got off the ground 10 years ago.”Those speaking at the conference appeared to be a mixture of conservative Christians, social conservatives, libertarians and “Maga-types”, he said.“It is clear what they’re against – internationalism, net zero, the denigration of national history – but these aren’t necessarily theological positions.

”Rob Ford, a professor of politics at the University of Manchester, said there was “no comparison whatsoever between the US and UK.Britain is one of the most secular societies in the world.Very few people go to church.The largest group are the people who say they have no religion at all.The kind of highly polarised debate that the Americans have had over abortion is inconceivable in the same way.

”But he added: “At the level of political elites, that’s where you get the most interesting similarity that is also a difference.In the US, evangelical Christians are a huge part of politics because they are a huge part of US life.Here you have quite a remarkably high density of evangelical Christians in elite politics.”Some evangelical Christian organisations have sought to nurture potential high-flyers in order to ensure a Christian presence in the upper reaches of public life.Half a century ago, the Iwerne Trust’s Christian holiday camps, mainly for boys attending elite public schools, had precisely this goal.

Holy Trinity Brompton, London’s foremost evangelical church, has counted many high-flyers among its congregation – including Marshall,Not all evangelical Christians share the same political views,Tim Farron, the former Liberal Democrat leader who resigned in 2017 saying the role was incompatible with his Christian faith, said the use of the term “Christian values” was sometimes “a proxy for things that aren’t very Christian at all”,He said: “People who talk about the loss of Christian values often have actually lost touch with Christian values themselves,It’s really dangerous when political parties seek to appropriate Christianity for their own ends.
