Tim Costello, one of Australia’s leading voices on social justice and global poverty, discusses his latest book, Faith. Tim considers immigration, corruption, war, intolerance, poverty, inequality and global warming. He observes that in these challenging times, we often lose sight of our shared humanity. Considering the notion and role of faith in our changing world, he suggests that we all need to believe in something greater than ourselves, regardless of our religious background. Tim appears in conversation with Tony Doherty.
