The Inquisition was not primarily an instrument of religious terror. It was a continent-wide intelligence apparatus β with informant networks, interrogation manuals, and cross-referenced case files spanning three centuries. The Jesuits were not merely missionaries. Their mandatory annual reports from every corner of the globe, written in compressed Latin and transmitted to Rome, constituted the first global intelligence reporting chain in history. The Soviet KGB did not simply monitor the Russian Orthodox Church. It owned it.
These are not conspiracy theories. They are documented historical facts β and Altars and Spies assembles them into a single, coherent argument: that religious institutions, across every major faith tradition and every historical period, operated some of the most extensive, durable, and effective intelligence networks ever known.
The book spans five millennia and six continents:
β The Oracle at Delphi as a pan-Hellenic intelligence clearinghouse, systematically debriefing visitors from across the Greek world under the cover of divine prophecy
β Kautilya’s Arthashastra (c. 300 BCE): a systematic manual for deploying holy men as state intelligence agents, 2,300 years before modern intelligence doctrine
β The Islamic Barid: a postal-intelligence network so feared that the first act of any provincial revolt was to arrest the local postmaster
β The Assassins’ deep-cover operatives, some embedded for over a decade at enemy courts before activation β the longest documented deep-cover programme in pre-modern history
β Japanese hidden Christians who maintained a clandestine network for 250 years without priests, headquarters, or external contact
β Buddhist monks CIA-trained in demolition and guerrilla tactics at a covert facility in Colorado
β A KGB document confirming that the World Council of Churches’ agenda had been successfully aligned with Soviet foreign policy
The structural argument is straightforward: no institution in history has matched religious organisations for the combination of geographic reach, trusted access, ideological loyalty, and plausible cover that effective intelligence requires. The technologies change. The underlying logic does not.
