Mark Pritchard MP called for the debate to discuss a growing intolerance of Christian values.
Members of Parliament have debated a perceived rise in intolerance towards Christians in Britain.
The 90-minute Private Members' debate on the sidelining of Britain's Christian traditions by the "politically correct brigade" was called by Mark Pritchard MP.
Several MPs agreed that there was such a thing as so-called 'Christianophobia', often promoted by what one described as "aggressive secularism". Many affirmed the value of Britain's Christian heritage.
The Christian Institute has frequently come to the aid of Christians who have been visited by police, threatened with the sack, or discriminated against in other ways because of their religious beliefs on moral issues.
Mike Judge, of The Christian Institute, was quoted in the Daily Express as welcoming the debate. He said: "Christians do feel they are being treated as second-class citizens in the name of political correctness."
Mr Pritchard said: "The roots of Christianity in Britain go back to the first century. Yet today there appears to be a reluctance by some public bodies and institutions to recognise our nation's Christian heritage and history."
He told the BBC: "It's gone far enough. If there are those who want to see the Christian church reduced to the margins in this nation they should have the courage to say so, rather than using the rights of other religions as an excuse."
