Sunday is Radio 4's flagship religious affairs programme, providing on-the-spot reporting, in-depth interviews and informed analysis of the major issues and their far-reaching developments, both in Britain and throughout the world.

Marking half a century of the programme, here are eyewitness accounts of landmark events, accompanied by astute critical reflection on their significance by Edward Stourton.

Set against an international backdrop of political, social and cultural upheavals, Sunday charts the events and their repercussions as they happened, and considers how they have changed the world as we see it today.

From popes and archbishops to the many ordinary Christians who have made a difference, from the rise of Islam to the decline in active church membership and the onslaught of the New Atheists, from internal battles between conservatives and liberals to engagement with issues of justice, peace and identity affecting people all over the world, Sunday will take you back to what it was like as these things emerged and evolved.

Sunday will enable you to see the role of religion in clearer and sharper focus, and to better appreciate its implications for our world, both now and in the future.
