I work in several quite diverse fields in both History and Religious Studies. Broadly, my major current interests include the study of global Christianity, past and present; of new and emerging religious movements; and of twentieth century US history, chiefly post-1975. I also have an enduring interest in issues of crime and deviance, and the construction of social problems. I have published more than twenty books, which have been translated into twelve languages. Some recent titles include The Next Christendom: The Rise of Global Christianity (2002), Decade of Nightmares: The End of the 1960s and the Making of Eighties America (2006) and The Lost History of Christianity(2008). My most recent book is Jesus Wars(2010) on the Christological controversies of the fifth century.
