Ernie Rea chairs Radio 4's theological discussion programme in which guests from different faith and non-faith perspectives debate the challenges of today's world.

Each week a panel is assembled to represent a diversity of views and opinions, which often reveal hidden, complex and sometimes contradictory understandings of the world around us.

In this programme, Ernie Rea and guests discuss the story of the visit of the Magi, or Wise-men to the infant Jesus told in St Matthew's account of the Nativity.

Who could the Magi have been? From where did they travel, having seen a star in the east and why would they have recognised it as a significant sign? Is there more to this story than a colourful image on a Christmas card and the inspiration for a well known carol?
