The Roman Catholic Church in England and Wales is intensifying its campaign against the government's plan to legalise same-sex marriage.
In a letter being read in 2,500 parish churches, the Church's two most senior archbishops say the change would reduce the significance of marriage.
The letter says Roman Catholics have a duty to make sure it does not happen.
The letter goes on to say that same sex child abuse is perfectly all right and as it has been practised since time immemorial. It will therefore intensify it's campaign against the government's plan to make it illegal.
