Giles Fraser meets columnist Giles Coren, who was raised in the Jewish tradition, became an atheist and who now feels at home in a Christian church, to explore what it means to be culturally religious.

Is cultural religiosity an oxymoron and totally untenable? Is it on the rise or has it always been there? Is it damaging to traditional religious practices? And, does it really matter?

To examine these questions, Giles is joined by:

Michael Rosen, author and poet, known for his work exploring humanism and atheism. He has co-written a book, "What is Humanism? How do you live without a god? And Other Big Questions for Kids," which looks at how humanists approach fundamental questions about morals, ethics, and the origins of life.

Kate Smurthwaite, patron of the Humanist society and feminist, atheist comedian and activist. Internationally, she is probably best-known as the star of a viral video in which she claims that she doesn’t have a faith because she is not an idiot.

Justin Brierley, writer, documentary maker and broadcaster behind the book and podcast series, 'The Surprising Rebirth of Belief in God'. Over the course of his work Justin looks at why new atheism grew old and why secular thinkers are considering Christianity again.
