A visit to the island of South Uist in the Outer Hebrides where the people still speak Gaelic and have retained their Catholic religion untouched by the Reformation.
There are three things that give South Uist its character - the faith, the language and the sea.
Lying 60 miles from the nearest Scottish mainland port, the island to a large extent has stronger links with Ireland than with Scotland.
This may be one reason why there are so many Irish touches about the people's religion, including the men's custom of standing outside the door of the church until the last possible moment.
This excerpt from the programme profiles the geography, religion and language of the island. The fact that Gaelic has replaced Latin for the celebration of the mass has given the language a new dignity on the island - it's the language that God speaks.
Parts of the Scottish Hebrides have preserved a way of life that has long ago vanished from the mainland. The reformation never came to the island of South Uist. Nor did the English language. The islanders have been Catholic and Gaelic for more than a thousand years but the pressures of the twentieth century are bearing heavily on them and the present generation of Gaelic speakers may well be the last.
Presented by Fr Peter Lemass, 'Radharc - The Island Where God Speaks Gaelic' was written and directed by Fr Desmond Forristal.
'Radharc: Where God Speaks Gaelic' was broadcast on 23 February 1971.
