Live broadcast from Southwark’s RC Cathedral

The 38-minute Sunday Worship broadcast on World Communications Day started at 8.07am following the news and review of the Sunday papers.

Visiting preacher Bishop George Stack, from the Westminster Archdiocese, took as his theme 'Who is my neighbour?' and during the short address explored the challenges of Christian identity in a multi-faith society.

Bishop Stack spoke of "communication between many faiths" and said that there was no better place than a church school "to bring down the walls of prejudice".

The Mass was introduced and celebrated by the Dean, Canon James Cronin, who described the cathedral as being "a few minutes from the Houses of Parliament" and near Waterloo Station and St Thomas' Hospital. He told listeners that the cathedral's congregation contained speakers of at least 63 different languages.

The music was led by the Cathedral Choir with the Girls' Choir sitting in the nave to boost the singing of the 75-strong congregation. Normally there are just a few present for the usual 8am said Mass although the total Sunday attendance at all five Masses is around 1,700.

The first choirboy arrived at 6am ready for a 7am rehearsal and the choir and congregation rehearsed the first hymn 'Father, Lord of all Creation' whilst the 8am Radio 4 News was being read in the BBC studio.

Communion was distributed after the Mass to allow for a smooth broadcast. The sound was faded during the last hymn leaving the congregation in Southwark to enjoy the rousing recessional music by Langlais.
