This episode looks at what drove Christians from the pews from the 1950s onwards, charting the social changes that saw a boom in non-belief.

The sharpest dividing line in Australian society was once a religious one: the often bitter division between Catholics and Protestants marked the postwar era and left its legacy in our education system.

Postwar migration saw Australia transformed from a broadly Christian monoculture to a successful multi-faith society.
