During a period of immense change and challenge for the United States, the Catholic Church, and the world, Francis Rooney served as U.S. Ambassador to the Holy See, the governing body of the Catholic Church, under George W. Bush from 2005 to 2008.

His new book, THE GLOBAL VATICAN, captures the interwoven nature of religious and political power and the complexities, battles, and future prospects for the relationship between the Holy See and the United States as both face challenges old and new.
