Douthat has published books on the
decline of religion in American society, the role of
Harvard University in creating an American
ruling class and other topics related to religion, politics and society. • His book
Grand New Party (2008), which he co-wrote with
Reihan Salam, was described by
New York Times commentator
David Brooks as the "best single roadmap of where the
Republican Party should and is likely to head." • Douthat's
The Decadent Society: How We Became the Victims of Our Own Success (2020) received positive reviews in
The New York Times and
National Review. • In 2025, Douthat published
Believe: Why Everyone Should Be Religious. Douthat frequently appeared on the video debate site
Bloggingheads.tv until 2012. In 2015, Douthat delivered the twenty-eighth
Erasmus Lecture, titled
A Crisis of Conservative Catholicism, hosted by
First Things magazine and the Institute on Religion and Public Life. In his lecture, Douthat examined the tensions within contemporary Catholicism following the
Second Vatican Council, focusing on how conservative believers have navigated questions of authority, reform, and tradition under modern papacies. He argued that the Catholic Church was facing an internal struggle over its moral and theological identity, reflecting broader cultural divisions within Western Christianity. ==Published works==
