Guglielmo Audisio (1802 at Bra, Piedmont, Italy – 27 September 1882 in Rome) was an Italian Catholic priest and writer.
[1] He then went to Rome, where Pope Pius IX appointed him professor at the Roman University, where he taught the law of nature and of nations.
In Rome Audisio joined the liberal reformist Italian ecclesiastics, such as Francesco Liverani, and tried to reconcile the new political and cultural needs of his time with Catholic tradition.
He urged Catholics to exercise their right and duty against political revolutionaries and Mazzini, rejecting all forms of abstention.
[2] At the time of the First Vatican Council he was suspected of Gallicanism, to the grief of his patron Pius IX, and his work on political and religious society in the nineteenth century was condemned by the Church.
