The British publishers claim "a lot of people have been led astray" by homosexuality.

But although they are braced for a backlash, they are planning a launch next month and a series of book signings by Canadian author Marion Heath.

Last night David Allison, of gay rights group Outrage, said: "This is implying that homosexuality is some sort of ailment, disease or affliction.

"The medical and psychiatric professions have acknowledged that isn't the case and it is just something that you happen to have.

"It's like a cold, except it's something that is permanently there, no matter what prayers you say, pills you take or gods you worship.

"It's not known how it's transmitted but if it turns out to be genetic then any biblical passages that condemn homosexuality fall flat on their face.

"These individuals just have an axe to grind." But publisher Eileen Mohr, 79, said she believed the book's theme.

She said: "We wanted this to be a more high-profile launch than we usually have because of the nature of the story.

"Our books deal with Christian themes and this is one we particularly believe in. We are expecting it to be controversial because of its claim that Jesus can cure homosexuals.

"We are ready for the controversy."

The book tells the story of Ryan, who leaves his wife and teenage children and moves in with his pal Tony.

He then has a dramatic experience that leads him to realise the power of Jesus and to reject his homosexual partnership.

Mrs Mohr, of Kidderminster, Worcs, said: "We are expecting homosexual people to object to the idea that Tony can be cured of his homosexual tendencies.

"We want them to read the book and find out more about the healing power of Jesus. I know Jesus can heal them."
