Atheist Delusions: The Christian Revolution and Its Fashionable Enemies is a 2009 book by theologian, philosopher, and cultural commentator David Bentley Hart. The book explores many of the historical and popular misconceptions of Christianity's detractors.
Hart explores the role of Christianity and its interactions with other faiths, with the objective of showing how very different Christianity is and was from the cults and religions of the time. He examines how it has changed, forming the basis of modern culture while dealing with the impact of the gradual decline that began with the separation of Church and state, as well as the age of war that resulted.
Rather than confronting each argument and counter-argument individually, Hart attempts to explain the people, history, events, and reasons behind them as he charts Christianity's rise, achievements, mistakes, and recent decline in the face of materialism and the power struggles of world leaders. Additionally, he aims to debunk the popular historical myths used to attack Christianity.
