A powerful, thought-provoking and always lively examination of how American Christianity has badly lost its way—with most of what goes by the name of Christianity today being one or another type of heresy—by the youngest writer ever appointed as editorial columnist for The New York Times.

In a world populated by “pray and grow rich” gospels and Christian cults of self-esteem, Ross Douthat argues that America’s problem isn’t too much religion; nor is it intolerant secularism. Rather, it’s bad religion. Conservative and liberal, political and pop cultural, traditionally religious and fashionably “spiritual”—Christianity’s place in American life has increasingly been taken over, not by atheism, but by heresy: debased versions of Christian faith that stroke our egos, indulge our follies, and encourage our worst impulses.

In a brilliant and provocative story that moves from the 1950s to the age of Obama, Douthat explores how bad religion has crippled the country’s ability to confront our most pressing challenges and accelerated American decline.
