Faith can be ephemeral - believing in an intangible power you can’t see or touch. But committing to a religion can be very concrete as you must follow the doctrines of that faith.

So what leads someone to take up a faith if they had none before? Or to convert from one faith practice to another? And once the leap of faith is taken, how does it impact that person and those around them? 

Someone who converted to a new faith is comedian and Buddhist Meshel Laurie. She's joined by Dr Rosemary Hancock, Senior Lecturer at Notre Dame, Assistant Director at the Institute for Ethics and Society and Convenor Religion, Culture and Society Research Focus Area.
