Written by political scientist David Ranan, Double Cross: The Code of the Catholic Church is a severe indictment of the many flaws, moral lapses, and outright crimes of the Catholic Church, ranging from parish sexual abuse scandals to complicity in genocide.

Covering the Church's perpetration of human misery from pre-medieval times to the Crusades to its tacit cooperation with the Holocaust and its ills of the modern Day, Double Cross examines how the Church has structured its power base, policed thought among its members, engendered corruption, fostered violence particularly against non-Catholics, espoused anti-Semitism, and perhaps worst of all among modern-day offenses, denounced nearly all forms of family planning as well as condom use, thereby causing overpopulation and assisting the spread of AIDS particularly in the poorest nations that can least afford either. Extensively researched with numerous notes to clarify details and an index, Double Cross is a "must-read" for anyone involved in or affected by the Catholic Church, both Catholics and non-Catholics alike.
