Atheist Delusions: The Christian Revolution and Its Fashionable Enemies is a 2009 book by the theologian, philosopher, and cultural commentator David Bentley Hart.

[citation needed] Hart attempts to explain the people, history, events, and reasons behind what he sees as Christianity's rise, achievements, mistakes, and recent decline in the face of materialism and the power struggles of world leaders.

[4][5] Philosopher Anthony Kenny called Hart's book "the most able counsel for the defence in recent years.

"[6] Writing for Commonweal, poet Michael Robbins described the book as "an unanswerable and frequently hilarious demolition of the shoddy thinking and historical illiteracy of the so-called New Atheists.

"[7] On 27 May 2011, the Archbishop of Canterbury, Rowan Williams, awarded the book the Michael Ramsey Prize in Theology.
