This week Belief turns the tables on a famous broadcasting voice. Church life was central to the small, working class community in Cumbria where Melvyn Bragg grew up. As a boy he sang in the choir, prayed every night and believed everything that the church taught him. He remains deeply influenced by the thought and cultural impact of the Christian faith. Melvyn Bragg tells Joan Bakewell how religion has permeated his writing and he explains why he returned to the church with his daughter after the death of his first wife.
