A new report from the thinktank Theos cuts through one of the more persistent confusions in British public life: the assumption that rising Christian nationalist rhetoric signals a Christian revival. It does not. The group most closely resembling Christian nationalists — 11% of respondents, labelled "identity integrationists" — overwhelmingly identifies as Christian (81%) but barely practices: just 13% attend church weekly, only slightly above the 11% national average. Less than a third pray weekly. Christianity, for this cohort, is a flag, not a faith. The contrast with genuinely observant Christians is stark and instructive. The "belief integrationists" — 13% of respondents — attend church at more than double the rate (31% weekly), pray weekly at 46%, and show far greater interest in the Bible (62% vs 47%). These are people for whom Christianity involves showing up, not just identifying. And their politics diverge sharply: 48% agree Christian values require welcoming asylum seekers, versus just 19% among the nationalist group. On equal treatment of religions in public life, the gap is 63% to 30%. The identity integrationists are defined less by theology than by anxiety. They are among the least ethnically diverse of the five groups Theos identified, and 90% believe defending Britain's Christian culture and heritage is important to being Christian — a position held by just 18% of the more practising group. Their Christianity is a perimeter fence, not a spiritual practice. The survey, conducted in April 2026 with 1,765 adults, also found that 37% of all respondents endorsed the "great replacement" conspiracy theory — that Europe's white population is being deliberately replaced by Muslim migrants. The broader population numbers carry their own warnings. More than half of Britons surveyed (55%) said they would be unhappy if their local church were converted into a mosque, including 37% who would be very unhappy. This suggests the cultural attachment to Christianity as national furniture extends well beyond the 11% nationalist core. The church building, even for non-attenders, functions as a territorial marker — its conversion registers as loss of place, not loss of worship. Nick Spencer of Theos drew attention to the gap between Christianity as idea and Christianity as embodied practice. Attending church, he argued, forces proximity with people you did not choose — "you don't choose who you're sitting next to in the pew" — which cultivates a different political temperament than treating Christianity as abstract heritage. The most practising group is also the most ethnically diverse (20% non-white), reinforcing the pattern: encounter with actual diversity through faith practice correlates with tolerance; identity Christianity without practice correlates with hostility. Bishop Arun Arora of Kirkstall offered the sharpest theological read: "They want to take up the cross at marches, and display it, but there's less of an interest in denying themselves and following Jesus." The cross as protest prop rather than instrument of self-sacrifice is the phenomenon in miniature. Theologian Helen Paynter added the global corrective — the average Christian worldwide is poor, female, and Black — a demographic profile that sits uncomfortably with the ethno-nationalist claim on the faith. The structural implication is clear: Christian nationalism in Britain is a political identity wearing religious clothing. Its growth tracks immigration anxiety and cultural displacement, not spiritual renewal. The churches themselves — multiethnic, globally connected, theologically committed to welcoming the stranger — are the institutional counterweight, but only if they engage beyond their walls. As Arora put it, waiting for people to enter the ark is not an option. The question is whether the institutional church can articulate its own tradition persuasively enough to contest the political appropriation of its symbols.
