This article investigates the attitude to communism, National Socialism, Fascism, and authoritarian conservatism in the Swedish Catholic Church’s journal Credo from 1922 to 1945. The comparative approach has made it possible to see how the journal distinguished between the various forms of authoritarian ideologies in Europe during this period. The article shows that the Catholic Church in Sweden took a very negative view of communism (the Soviet Union and the Spanish Republic) and strongly condemned it throughout the period, while it took a largely very positive stance towards Fascism (Italy) and Authoritarian Conservativism (Spain and Portugal). In the case of National Socialism (Nazi Germany) the attitude was more diverse. Credo was largely negative towards National Socialism but only because it was thought to threaten Catholics and Catholicism in Germany. However, Credo never criticized discrimination and genocidal violence against the Jews.
