Why religion fell off the radar in Australia - and how it can get back on At the time of Federation 98% of Australians identified themselves as Christians. Now only 8% say they regularly go to Church. What's changed? How did Australia become a post-Christian nation and what part did the Churches play in their own decline? Author Roy Williams (God, Actually, In God they trust?) has long been an impassioned defender of Christianity. Here, he tackles the decline of the church head on, acknowledging that in many cases, inflexibility, negativity and a refusal to listen have led to a tarnished image. But he also argues that Australia had a long and often misunderstood Christian heritage. And without it, he says, we will become a society with no moral centre, a community where rampant materialism is the only rule. Offering a bold roadmap for the Church to change, Williams challenges atheists, agnostics and true believers to a genuinely open debate about the force of faith.
