Mgr. Fulton J. Sheen Communism and the Conscience of the West (1948)

Apocalypse 18: [4] And I heard another voice from heaven, saying: Go out from her, my people; that you be not partakers of her sins, and that you receive not of her plagues. [5] For her sins have reached unto heaven. (Heaven on earth is the Mass)

“[Satan] will set up a counterchurch which will be the ape of the [Catholic] Church. . . . It will have all the notes and characteristics of the Church, but in reverse and emptied of its divine content.” MORE
