Vincenzo Gioacchino Raffaele Luigi Pecci

At every period of time each has been in conflict with the other, with a variety and multiplicity of weapons and of warfare, although not always with equal ardor and assault. At this period, however, the partisans of evil seems to be combining together, and to be struggling with united vehemence, led on or assisted by that strongly organized and widespread association called the Freemasons. No longer making any secret of their purposes, they are now boldly rising up against God Himself. They are planning the destruction of holy Church publicly and openly, and this with the set purpose of utterly despoiling the nations of Christendom, if it were possible, of the blessings obtained for us through Jesus Christ our Savior.

In consequence, the sect of Freemasons grew with a rapidity beyond conception in the course of a century and a half, until it came to be able, by means of fraud or of audacity, to gain such entrance into every rank of the State as to seem to be almost its ruling power.

It is now Our intention, following the example of Our predecessors, directly to treat of the masonic society itself, of its whole teaching, of its aims, and of its manner of thinking and acting, in order to bring more and more into the light its power for evil, and to do what We can to arrest the contagion of this fatal plague.
