[5] The leader, and sole staff member, of Christian Voice is Stephen Green,[6] a former Chairman of the Conservative Family Campaign, who attends an Assemblies of God Church.

[18] The group wants to overturn the law on marital rape, stating that the promises given by a man and woman to each other during the marriage service in the Book of Common Prayer establish a binding consent to sexual intercourse.

On 8 January 2007, submissions were made on behalf of Stephen Green at Horseferry Road Magistrates Court to pursue private prosecutions for blasphemy against the Director-General of the BBC Mark Thompson and the show's producer, Jonathan Thoday.

[25] A summons was refused on 30 January 2007 due to lack of prima facie evidence that a crime had been committed, and the provisions of the 1968 Theatres Act, which enshrines the right of free expression in theatrical works.

[27] On 5 March 2008 the House of Lords rejected the call to hear an appeal of the High Court's decision because "it did not raise an arguable point of law of general public importance".

"[33][34] On 8 January 2009, Christian Voice complained to the Advertising Standards Authority about the Atheist Bus Campaign's adverts on 800 buses across England, Scotland and Wales.

Peel said: It is a matter of some regret that ... the BBC should choose to undermine the reputation of Question Time by giving a platform to a small, self-selecting group distinguished by its claim to be a prophetic voice in this country ... Christian Voice has the right to express its extreme views, but it is as representative of Christian opinion in Britain as the Monster Raving Loony Party would be of mainstream political parties – and far less entertaining.

[48] In May 2008, Green was featured in the British Channel 4 current affairs documentary series Dispatches – In God's Name as a leader in the fundamentalist movement in the United Kingdom.
