On Start the Week Andrew Marr discusses faith and doubt. Richard Holloway started training for the priesthood from the age of 14, but as the former Bishop looks back on his life he reveals a restless spirit, always questioning his beliefs. Karen Armstrong has had similar crises of faith, and asks in a forthcoming talk, 'What is Religion?' For the 17th century Mexican nun, Sor Juana Ines de la Cruz, faith was wrapped up in her love of writing and poetry - her life is brought to the stage by the playwright Helen Edmundson. And Jonathan Safran Foer celebrates the Jewish text Haggadah which tells the story of the Exodus to the Promised Land.
