The Catholic Union is the leading lay organisation in Great Britain, whose primary objective is to champion the spiritual, moral and social teaching of the Catholic Church in the public sphere. It is the established voice of lay Catholics in this country.

The Catholic Union influences the changing nature of the parliamentary world where the Government itself relies upon the recommendations of expert Commissions, which in turn take public or invited evidence and advice.

The Catholic Union also seeks to uphold a Christian standpoint in public life, through educational activities, representations to Parliament, Government bodies and the media.
