The former Archbishop of Canterbury, Lord Carey, recently suggested that the Church of England may be extinct within a generation unless it learns to connect with young people. The Church of England is the most obvious example of a religious institution in serious decline, but it's certainly not the only one. Why is this happening? If our major religious institutions die, who will notice? And what might take their place?

Joining Ernie to discuss the future of religious institutions are the Rev Sam Wells, Vicar of St Martin in the Fields in London and a visiting Professor in Christian Ethics at Kings College London; Linda Woodhead, Professor in the Sociology of Religion at Lancaster University; and Jasjit Singh, Doctoral Researcher in the Department of Theology and Religious Studies at the University of Leeds.
