Bishop Plato Angelakis, an ordained Orthodox Catholic priest with the Oblates of St Therese in Wisconsin, US, said it was his first-ever exorcism and involved himself and a small group of other priests.
The victim, a 60-year-old woman, was said to have not "eaten or drank anything for a month" and so the priests visited her home to try and rid her of the evil presence.
Talking on The Exorcist TV Show Podcast, Bishop Angelakis explained what he saw.
"For the most part she showed extraordinary strength, three or four us, throwing us around the room - there were about four adults," he said.
As well as this disturbing display of physical strength, Bishop Angelakis recalled that the woman showed other telltale signs of possession too.
He said: "The whites of her eyes were all back, you try doing that, that's something you can't naturally do.
"Some language coming out, strength is probably the number one thing for her. She had extraordinary strength."
Fortunately, Bishop Angelakis said there was one thing in his favour while trying to get rid of this difficult demon.
He said: "For some reason, this particular entity could not leave the home. I don't know why. Once we got her out there was nothing.
"So when she was out of the home it was just fine."
It took two days to "liberate" the woman from the demon, he added, but her family remained practising Satanists.
Bishop Angelakis said that, at this point in his career with the church, he had "never encountered something like this before".
"To this day it is still one of the most intense exorcisms of a person I have ever encountered," he said.
This comes after a Catholic Archbishop claimed that victims of demonic possession can kill "with just their teeth" and have the strength of five men.
He also said they have "eyes as black as sharks" among other disturbing details.
And a woman claimed she was possessed by a demon as a teenager after being haunted and harrassed following her dabbling in Wicca magic with pals.
The ex-witch said she would smell "dead flesh" and wake up covered in scratches.
"Honey, I know your life was threatened but these rituals are just so cool!"
