Stephen Green, the director of anti-gay lobby group Christian Voice, will air his homophobic views in a short Channel 4 programme on Monday.
Mr Green is notorious for his remarks on homosexuality and recently accused gay rugby star Gareth Thomas of “promoting sodomy to children” for supporting LGBT History Month.
He will appear in 4thought, which is screened at 7.55pm every day on the channel. The five-minute films have weekly themes, with this week’s being homosexuality and religion.
According to promotional materials, the seven speakers shown this week will offer “radically different perspectives on homosexuality and sin”, including advocating the belief that God can cure homosexuality.
Mr Green is expected to quote from the Bible’s Book of Revelations to support his belief that God is against homosexuality. He will also argue that there has been a “homosexualisation” of British society and that gay people are destructive.
A Channel 4 spokeswoman confirmed that Mr Green was being given a platform.
When asked whether racist views would be given similar airtime, she said he would share his programme with a pro-gay Christian cleric.
In a later comment, the channel said: “Homosexuality is the theme of next week’s films because it has become a major battle ground for the world religions – for many it is seen as a sin in the Bible, the Koran and the Torah.
“4thought offers seven radically different perspectives on this subject. The aim of these films is provide an insight into why homosexuality is such a divisive issue in some of the world’s major faiths whilst also featuring personal reflections from individuals who have reconciled their sexuality with their faith.
“These 4thought films air less than a month after a Dispatches investigation into the persecution of gay people in African countries by Sorious Samura.”
Mr Green’s segment will be followed by one with the Rev Rowland Jide Macaulay, of the Metropolitan Community Church, who believes that those who use the Bible to condemn homosexuality are hypocritical as they should also advocate the stoning of adulterers.
Others in this week’s series will be a gay Hindu who believes his religion is compatible with his sexuality, a preacher who says God helped him overcome being gay and an Imam who says the Koran is evidence that men and women were created to be heterosexual.
