Canterbury Cathedral said the exhibit, which officially opens on 17 October, has given visitors “visceral reactions”.
“I think it’s sacrilegious,” said one cathedral-goer, while another questioned if the graffiti makes the historic site “look like an underground car park in Peckham”.
Mr Vance said: “It is weird to me that these people don’t see the irony of honoring ‘marginalized communities’ by making a beautiful historical building really ugly.”
The cathedral said the project partnered with Punjabi, black and brown diaspora, neurodivergent, and LGBTQIA+ groups.
Through a series of workshops, groups were asked to collaboratively respond to the question, “What would you ask God?”
The installation, created by poet Alex Vellis and curator Jacquiline Creswell, also features questions such as “Why did you create hate when love is by far more powerful?” and “Does everything have a soul?”
