Dr Bray said most deliverance ministers carry a bag, the contents of which he said people were “always intrigued by”.
“I’ve got various bits and pieces that I need,” he said.
“The most important thing I’ve got is a holy water sprinkler… The idea is that water is blessed and it’s then quite literally sprinkled around the house.”
Dr Bray also has a portable communion kit, which he said allowed him to celebrate mass in people’s houses.
“There are lots of people out there who don’t believe in the supernatural. There are lots of people out there who don’t believe in God, and that’s fine,” he said.
“I’m not imposing my beliefs on you, and I don’t expect you to impose your beliefs on me.
“What’s really interesting is the number of people I come across who don’t believe in God, but also believe in ghosts, and for me that’s just a little bit puzzling.”
A spokesperson for the Church in Wales said: “Deliverance is a key part of the ministry we offer.
“Each of the Church in Wales’ six dioceses has a deliverance minister. They are licensed by their bishop and they make up the deliverance team.
“They are fully trained in a programme we share with the Church of England and they work closely with our safeguarding officers and medical professionals.”
