"In the work on the end of the world, ascribed to St. Hippolytus, ... we read as follows: 'The Churches shall lament with a great lamentation, for there shall be offered no more oblation, nor incense, nor worship ACCEPTABLE to God. The sacred buildings of the churches shall be as hovels; and the precious body and blood of Christ SHALL NOT BE MANIFEST in those days; the Liturgy SHALL BE EXTINCT; the chanting of psalms shall cease; the reading of Holy Scripture shall be heard no more. But there shall be upon men darkness, and mourning upon mourning, and woe upon woe.' Then, the Church shall be scattered, driven into the wilderness, and shall be for a time, as it was in the beginning, invisible, hidden in catacombs, in dens, in mountains, in lurking-places; for a time it shall be swept, as it were, from the face of the earth. Such is the universal testimony of the Fathers of the early centuries."
-Cardinal Manning relating the UNIVERSAL TESTIMONY of the Fathers of the Church (which constitutes part of the Sacred Deposit of Faith, Catholics are REQUIRED to believe) that the True Church with Her Perpetual Successor and Holy Mass (APPROBATED by him) - will be "hidden in catacombs" during the terrible persecution - prior to the triumph of the Papacy over its profane enemies (such as the Schismatic N.O. [and its sspx] - and seditious sedevacantists). Source: "The Present Crisis of the Holy See Tested By Prophecy: Four Lectures" p. 79
