"The idea is to show the world that people of all sorts of different faiths care deeply about the Occupy protest and the issues it is trying to raise.
"Each person will make their own decision on what they want to do. Some will go if asked by police, but others will politely refuse and will have to be forcibly removed."
Senior leaders at St Paul's will view the plans with a deep sense of unease. The cathedral was thrown into turmoil when the Occupy protest first camped on its doorstep and was severely criticised for appearing to side with the City against the protesters.
Three of the cathedral's clergymen, including the Canon Chancellor, Giles Fraser, resigned in protest at the decision by senior officials to press for an eviction.
So far, more than 260 people have signed up to a petition to form part of the ring of prayer. Among the Christian groups supporting the Occupy camp are the Fellowship of Reconciliation - one of Britain's oldest Christian charities - the Student Christian Movement, Christianity Uncut and the evangelical Christian magazine Third Way. In a joint statement, they said: "As Christians, we stand alongside people of all religions who are resisting economic injustice with active non-violence."
