The Queen attending a service celebrating 150 years of the Scripture Union, televised by the BBC

Katherine Jenkins hosts a special programme as Songs of Praise joins Her Majesty the Queen to celebrate 150 years of the Christian charity Scripture Union. We discover how one man teaching Bible stories to children in north London in 1867 started a movement that now works in 130 countries around the world. One of our most cherished modern hymn writers Bishop Timothy Dudley Smith reveals how, even in his nineties, his faith continues to inspire him to write music. And Pam Rhodes meets Douglas Gresham, the stepson of the great CS Lewis, to find out how he let the light of his Christian faith shine through his children's books.
