Michael is a top authority on anti-Semitism, particularly as it relates to Christianity. There is no book currently available that examines anti-Semitism over the entire history of the Catholic Church. Frederick M. Schweitzer, director of the Manhattan College Holocaust Center and co-author of "Anti-Semitism", wrote that the book 'promises to become a standard work on the history and nature of anti-Semitism in the Catholic Church.' Eunice Pollack describes the book as 'a masterful work that systematically exposes the deep roots of anti-Judaism and anti-Semitism in the Christian Testament.' Moving from the Catholic Church's pagan origins, through the Roman era, middle ages, and Reformation to the present, Robert Michael here provides a definitive history of Catholic anti-Semitism.
