The Roman Catholic Church
Although the CIA began as a mostly Protestant organization, Roman Catholics
quickly came to dominate the new covert-action wing in 1948. All were staunchly
conservative, fiercely anti-communist and socially elite. Just a few of the many
Catholic operatives included future CIA directors William Colby, William Casey,
and John McCone. Another well-known personality from this period was William
F. Buckley, Jr., editor of the National Review and gadfly host of TV’s Firing Line.
Buckley, it turns out, served as a CIA agent in Mexico City, and his experiences
there served as fodder for his Blackford Oakes spy novels.
