"Haec S. Congregatio pro Doctrina Fidei, facto verbo cum Beatissimo Patre, nuntiat Indicem suum vigorem moralem servare, quatenus Christifidelium conscientiam docet, ut ab illis scriptis, ipso iure naturali exigente, caveant, quae fidem ac bonos mores in discrimen adducere possint; eundem tamen non-amplius vim legis ecclesiasticae habere cum adiectis censuris" (Acta Apostolicae Sedis 58 (1966), p. 445).

"The entanglement of Church and state power in many cases led to overtly political titles being placed on the Index, titles which had little to do with immorality or attacks on the Catholic faith. For example, a history of Bohemia, the Rervm Bohemica Antiqvi Scriptores Aliqvot[...] by Marqvardi Freheri (published in 1602), was placed on the Index not for attacking the Church, but rather because it advocated the independence of Bohemia from the (Catholic) Austro-Hungarian Empire. Likewise, The Prince by Machiavelli was placed in the Index in 1559 after it was blamed for widespread political corruption in France (Curry, 1999, p. 5)" (David Dusto, Index Librorum Prohibitorum: The History, Philosophy, and Impact of the Index of Prohibited Books).Archived 20 October 2012 at the Wayback Machine
