Far be it for Mouse to suggest he is ahead of the curve, but 15 months after Mouse observed the need to understand how the Church of England does its doctrine and published a comprehensive guide to the subject, the good old CofE has had a go itself.
To consider the nature and grounds of Christian doctrine with a view to demonstrating the extent of existing agreement within the Church of England and with a view to investigating how far it is possible to remove or diminish existing differences.

Yikes.
Is it possible to hold multiple doctrines simultaneously, in order to respond in the most gracious and pastoral way possible, even when this is messy or incoherent? Is it possible for there to be a range of interpretations of one doctrine?

The findings are also inconsistent with other data from YouGov, the polling firm that collected the data for the Bible Society. A decade ago, the British Election Study (BES) commissioned YouGov to create an online panel. This panel, which includes more people than the Bible Society surveys, was asked about religious affiliation and church attendance in 2015, 2022 and 2024.
According to YouGov’s data for the BES internet panel, the share of Christian churchgoers in England and Wales declined from 8.0% to 6.6% between 2015 and 2024, whereas YouGov’s surveys for the Bible Society apparently show an increase from 8% to 12% between 2018 and 2024.
Reporting suggested that the same questions were asked in the two surveys, which is technically true in the sense that the questions driving these results were worded in the same way. But in one of the surveys a number of other questions were asked before getting to the crucial ones on church attendance.
In the 2024 survey, before asking how often the individuals attended church in the last month, an additional series of questions was asked. Participants were asked whether they think ‘It’s important to me to try to make a difference in the world’ and whether they agree with statement like ‘My life feels meaningful right now’. In total eight additional questions were asked of this nature.
There is a very well known psychological phenomenon called priming, whereby you can incluence thoughts and behaviours through the use of an earlier stimulus or prompt. One example is that you can get a different answer to the same question depending on whether that person has been primed to think in a particular way beforehand. In one famous study, people were asked to guess the date the Mongul ruler Genghis Khan died (1227). Half the group were asked to write down the last three digits of their phone number before making their guess and half were not. The group who were primed to think of an unrelated three digit number were more likely to guess a date before the turn of the first millennium - in other words they were primed to guess a three digit number.
So Mouse is left to speculate whether being asked if you feel connected to your community and have a meaningful life immediately before being asked if you attended church recently has a similar priming effect. In some respects, it would be a surprise if it did not.
The 2018 survey fieldwork was done between 11 October and 13 November, while the 2024 survey was just a couple of weeks later from 4 November to 2 December.
Ordinarily a two week difference would not be considered significant, but looking at the dates makes Mouse speculate whether it had an impact in this case. It certainly isn't speculation that in December you are running into a lot more Christmas trees and hearing a lot more of Wizzard wishing it could be Christmas every day than you are in October. Halloween took place during the 2018 fieldwork, but had already passed by before the 2024 fieldwork period and the Christmas build up was in full swing. It is possible this timing difference had an effect.
The 2018 survey had just over 19,000 participants while the 2024 survey had just over 13,000 participants. Presumably, since they asked more questions in the second survey they saved some money by cutting back on the sample size.
That begs the question how the demographics of the two different sized samples were balanced to ensure comparability. No doubt YouGov will have made every effort to strike a demographic balance in these two samples, but that is no easy task. There is no gold standard for ensuring a group of people are equally likely to go to church or not, so there is a possibility the samples had an effect. The sample picked people and weighted the sample to achieve an equal mix of age, gender and ethnic diversity. That would help, but if there were other differences in the demographics, such as a mix of social classes or a bias between urban and rural, these would have a significant impact on the likelihood of church attendance but would be very invisible in the YouGov methodology.
Gold standard social surveys are based on random (probability) samples of the population: everyone has a chance to be included. The British Social Attitudes survey is one such example – and found that churchgoing fell by nearly a quarter from 2018-23.
By contrast, people opt in to YouGov’s survey panel and are rewarded after completing a certain number of surveys. The risk of low-quality or even bogus responses is considerable.
Passing the sniff test
There are some anomalies in the Bible Society data which indicate a problem with the samples which should make us stop and think. Take the number of people reporting that they go to church 'Daily / Almost Daily'. In 2018 the result for 18-24 year olds was 0%, as we would expect, but it jumped to 2% in 2024. The equivalent figure claiming attendance 'a few times per week' also jumped from 1% to 7%. At face value, an incredible increase. That single data point has contributed enormously to the narrative that it is the young who are behind a jump in attendance, almost itself explaining the total jump in monthly attendance reported. But if we are honest it is simply not credible to believe by extrapolation from the 28 people who ticked the 'daily / almost daily' box (that is 2% of the 1,400 sample in that group) and the 98 people who ticked the 'a few times a week' box that there are now almost half a million 18-24 year-olds attending church almost every single day. If we are to believe these numbers, the average demographic in church for daily prayers through the week would have more 18-24 year-olds than any other age group. Is it a coincidence that these answers were the top two in the list of answers? It seems to Mouse a more credible explanation that the people being paid to fill in the survey just ticked a box high up the list without reading it properly or caring much what they were ticking.
On Radio 4's More or Less programme, 'The Undercover Economist' Tim Harford posited several possibilities to explain the anomalous data. The 2018 survey could have been an ‘outlier’ poll with attendance coming out too low. The 2024 poll could have been an ‘outlier’ poll in the other direction. It is possible that a sudden upswing genuinely has happened late in 2024 after the denominational counts had taken place, and other data is yet to catch up with the sudden and dramatic turnaround. The conclusion was that more data is required.
But Mouse wonders what the response to these two surveys would have been if they had shown an unexpectedly large decline in church attendance. Presumably, Church commentators would have analysed the methodology, compared the results with other authoritative sources and concluded that it was a rogue poll. What a shame similar rigour has not been applied in this case.
As for Mouse, sadly he feels that the most likely explanation for the unexpected report of rising church attendance is that there is a bit of bias in the surveys for the reasons outlined above, and a few self-selecting survey responders didn't bother to answer very honestly.
Mouse clings on to some hope that this instinct is wrong and there genuinely has been a sudden and unexpected cultural shift, but none of the explanations he has yet heard have convinced him, and the evidence to the contrary is strong.

Mouse recently confessed to someone that he was sceptical that a quiet revival was underway in the UK, and the response he got was a frustrated, "Don’t you believe in Jesus?"
So here I am making my confession. I’m The Church Mouse and I’m a ‘quiet revival sceptic’. But I still have hope.
In case you have missed it, the ‘quiet revival’ is the title of a report from the Bible Society that has made the stunning claim that the Church in England and Wales has, despite everything we have previously believed, experienced dramatic growth in recent years.
The most extraordinary claim is that, in the past six years (i.e., since just before the pandemic), the Church in England and Wales, across all denominations, has grown by more than half, from a total of 3.7 million regular worshippers to 5.8 million. The report says that it is largely the young who are driving this, in contradiction to our previous assumption that every generation is less religious than their parents.
The evidence for these claims comes from a large survey undertaken by a highly respected polling organisation, YouGov, that whether they had attended a church in the past month, among other questions. The same question set and methodology six years previously reveals a 56% increase in attendance.
And none of us noticed.
Reaction has largely been one of joy, mixed with anecdotes supporting the conclusions and speculation as to the reasons.
‘I had noticed more people attending recently, so it has the ring of truth about it!’
‘Young men are increasingly in search of purpose.’
‘Gen Z are much more spiritually open than previous generations.’
This is the sort of thing that church social media is full of.
Numerous articles have been written to explain this growth. We have been treated to explanations of how Gen Z is simply a different sort of human being from Gen Y or us oldies of previous vintages. Apparently, they are more open to spirituality and not burdened by old assumptions around faith. We are told that they don’t have the same sense of hope that previous generations had, so they are searching for new sources of meaning and purpose, and it is the young who are fuelling the growth.
So let Mouse unpack what this survey is actually saying and then form a view, to the extent that we can from the available evidence.
Firstly, the survey is not a measure of the number of people who have attended church regularly. It is a measure of the number who said that they have attended church regularly. Those are not the same things, and we must test whether there is a gap between actual attendance and claimed attendance before going any further.
Pollsters have long experienced the phenomenon of inaccurate responses in political polling. Perhaps most famously, the 1992 general election was widely predicted to be a Labour win. When the Conservatives secured a 21-seat majority, the pollsters looked at their numbers to work out what went wrong. They had accurately reported how people told them they would vote, and their samples were representative. But they coined the term ‘Shy Tories’ to explain the phenomenon. Some felt a sense of social embarrassment in telling someone they intended to vote Tory, so they either said ‘don’t know’ or declined to respond. They have since learned to make adjustments for this type of thing.
When it comes to polling on church attendance, no such methodological rigour exists. The polling firms can only report what they are told by members of the public and aim for samples that are large and as demographically representative as possible. So the minimum this survey can tell us is that more people are claiming to go to church than was the case six years ago.
This Mouse would be absolutely overjoyed if this turns out to be the reality, but let me set out a few (evidence-based) reasons why he finds it hard to believe.
Some of the churches where the Bible Society reported significant growth actually count the number of people who walk through their doors, and the numbers don’t match.
The most robust data set by a UK denomination is from the Church of England. Each church counts the number of worshippers during the same period each year, and the numbers are compiled to create a robust, consistent data set. The data shows that over the past six years, the Church has shrunk by between 10-20%, depending on how you count it.
Some commentators have responded that the Church of England is the exception, not the rule. Mired in conflict over sexuality and having high-profile sexual abuse cases in recent years, we should simply ignore the Church of England. The growth is elsewhere, we are told.
The Head of Research for the Bible Society, Dr Rhiannon McAleer, has made this argument.
“Some churches, like the Church of England and Methodists are very good at counting attendance within their churches and these data sets clearly show decline. This is picked up in the media and extrapolated to the wider picture, when it is not necessarily a fair indication of what’s going on in many denominations and churches who don’t collect attendance statistics.”
But that is not what the Bible Society report says. We can see in the data exactly what they are reporting for the Church of England. They are reporting significant growth.
According to their data, 41% of the English and Welsh Church attendance in 2018 was in Anglican settings. Based on a total regular attendance of 3.7m people, we can calculate the Anglican attendance at around 1.5m. By 2024, Anglicans had reduced as a proportion to 34% but of a much larger reported attendance of 5.8m people, so we should be seeing an increase in attendance of around 500,000 to around 2m. In other words, the report claims that the Church of England has grown by a third since 2018.
The Church of England has a range of measures of attendance, but even its most favourable measure of the ‘worshipping community’ is 8% smaller in 2024 than it was in 2018. By stricter measures, such as the average Sunday attendance, the CofE is more like 20% down, despite small increases in numbers since the pandemic lows.
Mouse notes that the Bible Society report includes Wales, however, the Anglican Church in Wales reported attendance of just 26,000 in 2018, so it is safe to assume the vast bulk of these numbers are from the Church of England.
The same methodology can be applied to the data for the Catholic Church, the next largest denomination. The report said that it has grown from 23% of attendees in 2018 to 31% in 2024, meaning it would have grown from around 850,000 regular attendees in 2018 to 1.8 million in 2024, spectacular growth of almost a million regular worshippers.
The Catholic Church in England and Wales reported regular mass attendance down around 20% from pre-pandemic levels, to 555,000 in 2023 from 702,000 in 2019.
Between them, these two denominations have reportedly grown their regular attendance by almost 1.5m people, out of the total reported growth of 2.1m, or over 70% of the total growth. But Church attendance data simply does not back that up.
If we are to take seriously the claims from the Bible Society / YouGov report, someone must come up with a plausible explanation for how it shows growth in attendance of 1.5 million people in denominations whose own statistics show decline.
It is certainly possible that there has been growth in other denominations, but when we have good reason to believe that over 70% of the growth claimed by this report is non-existent, it is hard to believe that the overall picture is anything like the headlines.
Mouse is a little frustrated that the actual questionnaire and data tables from YouGov are not available. That is not to suggest anything is being deliberately hidden, but for anyone looking to understand the data better, this would be invaluable. There may be a better way to understand the numbers, but Mouse cannot work out what that is. There may be more nuggets to be mined from the data tables if they are available, but for now, Mouse has to draw stumps at this point.
So where does this leave us?
Mouse’s take is that it is far from clear that more people are attending church than was the case in 2018, based on actual data from the two largest denominations in Britain. More solidly, we have pretty firm grounds for believing that nothing like the 56% increase is happening in reality, even if there is some growth in some places.
It is perhaps most interesting that people are claiming they attend church more frequently, even if they aren’t actually doing so in practice. For some time there was a bit of a social stigma in certain circles about religiosity. The New Atheist movement had created a hostile environment by arguing that religious faith was the preserve of the ignorant and needy. Many felt the need to move their faith into the private sphere in the face of this. That has largely died away. Perhaps the ‘Shy Christians’ are prepared to say what they really think more now.
But Mouse would conclude by zooming out a little on the macro trends. Church attendance and religious affiliation in Britain has been on the slide since before the Second World War. This has been well evidenced in church attendance data and robust surveys, such as the British Social Attitudes Survey and the Census. Perhaps it will turn around. Perhaps it has already started to do so, but Mouse urges that we not underestimate the depth and profundity of the social forces that have been driving that decline for the past century. Patterns of behaviour learned and passed on from one generation to the next have changed. New habits, behaviours, attitudes and beliefs have replaced core assumptions of previous generations. Turning this round will not be driven by a TikTok meme or a passing fad.
Facing into these uncomfortable truths is not a lack of faith or hope, but simply a recognition of the reality in which we live. In fact, it is only by facing this truth that we can have hope that we will turn it around. This Mouse still has hope, but it remains a hope in things we have not seen.

Mouse was intrigued by newspaper reports of a new survey claiming to have found that Gen Z are the most spiritual generation and the least committed to atheism. The claims looked compelling but need a deeper look.
Is this due to a rise in people with unorthodox combinations of beliefs, shunning organised religion but believing in eternal damnation? That may be an intuitive solution – but it’s not the answer.
later generations do include a higher proportion of people from immigrant backgrounds (a person was classified as having an immigrant background if either they described themselves as an immigrant or described both their parents as an immigrant), though this has actually levelled off in Gen Z, which is probably only because the Gen Z cohort is still too young, with birth years between 1997 and 2012, for many Gen Z adults to have immigrated to the UK from abroad, compared to preceding generations.
