Catholic holocaust scholar Michael Phayer concludes that the encyclical "condemned racism (but not Hitler or National Socialism, as some have erroneously asserted)". Other Catholic scholars have regarded the encyclical as "not a heatedly combative document" as the German episcopate, still ignorant of the real dimension of the problem, still entertained hopes of a Modus vivendi with the Nazis. As a result, the encyclical was "not directly polemical" but "diplomatically moderate", in contrast to the encyclical "Non abbiamo bisogno" dealing with Italian fascism.
