Defending the Nation Under God: Global Catholicism, the Supreme Court, and the Secularist Specter (1946–1963)

ABSRACT This essay relies on American and newly available Vatican archival sources to reconstruct the ins and outs of the U.S. Catholic Church's involvement in First Amendment litigation between the 1940s and the 1960s. These reveal how Catholic leaders, far from urging the demise of the de facto Protestant establishment, cooperated with Protestants to protect it from legal challenges. They did so not because gaining the acceptance of their non-Catholic neighbors was their paramount concern, nor because American Catholics were more “liberal” than their Roman counterparts. Rather, they saw the “Nation under God” as effectively addressing traditional Catholic critiques of the liberal principle of church-state separation—and therefore a project worthy of their commitment. Ironically, while pursuing goals fully compatible with Roman orthodoxy, they found themselves allied with evangelist Billy Graham and Gideons International long before the Second Vatican Council (1962–1965) and Roe v. Wade (1973).
