Enticing the next generation through their ancient doors, keeping donations topped up and ensuring that the organ is tuned usually rank high among any church’s list of priorities.
For one congregation in Leicester, however, their problems have been somewhat more ungodly. For years, members of All Saints Church in Braunston-in-Rutland have been plagued by faeces dropping from the ceiling where a 500-strong colony of bats now reside.
This has meant that instead of praying or enjoying the 1,000-year-old church building, parishioners have been slipping on its floors, art and furniture has been covered in sheeting and volunteer wardens have spent hours scouring pews and floors of bat excrement.
Now, however, the congregation remains clean and dry. Following a pioneering new scheme, entitled the Bats in Churches project, work has been done to fill the gaps in the ceiling to prevent faeces and urine soaking through without harming the animals.
It is illegal to stop bats - which are a protected species - from reaching their roost, leaving many churches unable to patch up holes in their walls and doors which bats use for access. As a result, many congregations across the country have often found themselves at the receiving end of their sporadic, plunging excrement.
All Saints Church was one of the first to benefit from £3.8million of Heritage Lottery Funds to reduce the impact of bats on the buildings across the UK. It is one of around 100 churches, which hosts a large bat roost, which is now reaping the rewards of clean floors and clean congregants.
Sue Willetts, church warden, told the BBC: "Before, we had covers down on the floors to collect the droppings.
"We had to clean the pews every time, it took an hour before every single service. Now we use the church how its meant to be."
Mrs Willetts said that the bat problem “snowballed” five years ago when an old chimney in the village collapsed, prompting its residents to move into the church instead.
She added that after signing up to the scheme, ecologists found gaps between the roof and the church and it was possible to block these gaps without harming the bats.
She estimated that the church has received £100,000 worth of scaffolding, building, and ecological study works since applying for funding from the project.
Rosemary Riddell, from the Bat in Churches project, said work at All Saints Church "has enabled us to sort of roll out solutions to other churches similar to Braunstone and it's really helped us to learn from their experiences".
"[The church] was one of our guinea pigs and we're grateful for their engagement and involvement," she added.
More than 100 churches have applied for the Bats and Churches Partnership, which monitors bats to see whether church managers could be allowed to take action to protect their historic buildings. It is funded by a multi-million-pound National Lottery grant.
During the General Synod earlier this summer, The Telegraph reported that bats in the belfry were being mooted as a potential “tool for mission”.
Bishops visiting York were asked to answer more than 100 questions involving an array of controversial topics such as reporting abuse during confession, non-disclosure agreements and ethical investments in large technology companies; and one was on bats.
The Archdeacon of Lincoln, the Venerable Gavin Kirk, asked for an update on the progress of the Bats in Churches project, and “how those afflicted by bats may find out more about it?”
Sir Tony Baldry, chair of the Church Buildings Council, responded: “A number of projects involve volunteers from the community in managing and even exploiting the presence of bats, for school projects and the like. Bats might even prove to be a tool for mission, if we can get them to behave politely.”
Asked how bats may prove to be tools for mission, Sir Tony told the media: “We have to work out how to encourage them out of the belfry to roost in bat boxes in churchyards.
“They could then be of interest for projects for schools and A-level students studying the life cycles of bats and so on. They are part of God's creation and are interesting mammals.
“There are serious challenges. They poo and urinate over large parts of the church, it is very distressing for parishioners on a Sunday to have to clear a whole load of bat poo off the altar and pews and so for some churches that bats have made almost unusable.”
