26 August 2012 Last updated at 09:51 BST

Roman Catholic priests are to read out a letter in each of the Church's parishes in Scotland criticising the Scottish Government for plans to introduce gay marriage.

Last week the leader of the Church in Scotland, Cardinal Keith O'Brien, broke off discussions about the issue with the First Minister, Alex Salmond.

The church has declared 26 August as National Marriage Sunday.

The Scottish Government has stressed that no clergy would be forced to carry out same-sex marriages.

The BBC's religious affairs correspondent Robert Pigott reports.
