In this essay, I argue that despite the Vatican’s condemnation of Nazi racism as an anti-Christian ideology, some Catholic sectors in Fascist Italy were not impervious to anti-semitic and racial prejudices. Looking at the discussion on race and anti-semitism in the propaganda of clerical Fascism and its simultaneous echo in Church discourses, this research delves deeper into the formation of a specific Catholic trend of racial anti-semitism that excluded Jews from a religiously and ethnically homogeneous definition of the Italian nation. A significant part of the propagandists of clerical Fascism attempted to define a racial and anti-semitic narrative that could be suitable for both Fascist racism and Italian Catholic culture. I examine the Catholic appropriation of racial anti-semitism on a broad spectrum of positions, ranging from Catholics who only flirted with racialist rhetoric to those who dismissed the transformative value of conversion because of alleged racial barriers. Challenging the traditional distinction between Christian anti-Judaism and modern anti-semitism, the examples under examination demonstrate the entanglement of religious and racial arguments in the shaping of a ‘Jewish race’ that was considered foreign to the italianità celebrated by the regime.
