Inimica vis (On Freemasonry) was a Papal Encyclical addressed to the bishops of Italy. It remarked on the multiple condemnations of Freemasonry over the preceding century and a half and concentrated on the local difficulties of the Italian church. It was promulgated by Leo XIII in 1892. It is still quoted in current Catholic criticisms of Freemasonry. On the same date as Inimica vis was promulgated, (18 December 1892), Pope Leo XIII wrote Custodi di quella fede, an encyclical epistle addressed to the Italian people, attacking Freemasonry.
