May 1, 1924 Nuncio Pacelli identifies nationalism or National Socialism as the most dangerous “heresy” of the era, in a report to Vatican Secretary of State Gasparri.
Sources: Compare G. Besier, The Holy See and Hitler’s Germany, p.35, citing ANM, pos. 396, fasc. 7, p. 79v (“nationalism is perhaps the most perilous heresy of our time”) with R. Rychlak, Hitler, the War, and the Pope (2010), p.44, citing ANM, 396, fasc. 7, pos. XIV, Bavaria, p.75 (“Nazism is probably the most dangerous heresy of our time”).
Note: The online publication of Nuncio Pacelli’s reports more recently shows that this report refers to nationalism and attacks by the German Völkisch press upon the Pope, Cardinals including Faulhaber, and the Nuncio; none of the attacking press organs cited by Pacelli were identified in his report as Nazi.
The original Italian says “il nazionalismo sia forse la più pericolosa eresia dei tempi nostri.” Citation: Pacelli to Gasparri, 1 May 1924, Dokument-Nr. 181, online at www.pacelli-edition.de/dokument.html?idno=181 (accessed Sept. 1, 2020)
