 The earliest documented uses of the term “fideism” are to be found in French theology. Thomas D. Carroll has located references to fidéisme from as early as 1854 (2008, 10); however, the term appears to have entered into broader circulation in the literature a quarter-century later, when it came to be used pejoratively in reference to Catholic traditionalism by theologians seeking to revive the Thomistic synthesis of reason and faith.
