A former counterterrorism official explores how modern evangelicalism and right-wing conservatism intermingled to form the combustible ideology that resulted in the January 6 attacks on the Capitol--and which threatens to destroy the American Church from within.   How did a Church that purports to follow the teachings of Jesus - the Prince of Peace - become a breeding ground for violent extremism?   When Elizabeth Neumann began her anti-terrorism career as part of President George W. Bush's Homeland Security Counsel in the wake of the September 11 attacks, she expected to spend her life protecting her country from the threat of global terrorism.   But as her career evolved, she began to perceive that the greatest threat to American security came not from religious fundamentalists in Afghanistan or Iraq but from white nationalists and radicalized religious fundamentalists within the very institution that was closest to her heart - the American evangelical church. And she began to sound the alarm, raising her concerns to anyone in government who would listen, including testifying before Congress in February of 2020. At that time, Neumann warned that anti-Semitic and white supremacist terrorism was a transnational threat that was building to the doorstep of another major attack. Shortly after her testimony, she resigned from her role as Department of Homeland Security Assistant Secretary for Counterterrorism and Threat Prevention in protest of what she believed was then-President Trump's failure of leadership and his stoking of the hatred, anger, and division from which she had dedicated her life to protecting her country.   Her worst fears came true when she witnessed the attack on the capital on January 6, 2021.   In Kingdom of Rage, Neumann explores the forces within American society that have encouraged the radicalization of white supremacist, anti-government and other far-right terrorists by co-opting Christian symbols and culture and perverting the faith's teachings. While Neumann offers decades of insights into the role government policies can play to prevent further bloodshed, she believes real change must come from the within the Christian church. She shines a bright light on the responsibility of ordinary Americans - and particularly American Christians - to work within their families and their communities to counteract the narrative of victimization and marginalization within American evangelicalism. Her goal for this book is not only to sound a warning about one of the greatest threats to our security but to rescue the Church from the forces that will, if left unchecked, destroy it - culturally, morally, and ultimately quite literally. This is a book for anyone who wants to understand the unholy marriage of right-wing politics and Christian exceptionalism in America and who wants to be a part of reversing the current path towards division, hatred, violence and the ultimate undermining of both evangelical Christianity and American democracy.
