The following excerpt is from: "What Catholic Faith Is", by
the highly esteemed Theologian, Fr.
Michael Müller, C.SS.R:
St. Basil says: "Faith, always
powerful and victorious, exercises a greater ascendancy over minds than all the proofs which reason and human science can furnish, because faith obviates all difficulties, not by the light of manifest evidence, but by the weight of the infallible authority
of God, which renders them incapable of admitting any doubt." ...
This is the reason why the Church allows
none of her children to call into question her divine mission. The light of faith which shines upon the mind of a Catholic so utterly consumes doubt, that, hereafter he cannot entertain it except by his own great fault.
"Faith," says St. Alphonsus, "is a virtue, or a gift, which God infuses into our souls in baptism, by which gift we believe the truths which God himself has revealed to the Holy Church, and which she proposes to our belief.

Pope St. Caius stayed *hidden in the Catacombs for 8 years to preserve himself for His flock.
The Saint was eventually captured and martyred (via decapitation). St. Caius' tomb,
with the original epitaph, was discovered in the catacomb of Callixtus
in Rome.
*"St. Caius encouraged St. Sebastian, and the other martyrs
and confessors. However, to preserve himself for his flock, he withdrew for a time, to avoid the fury of the storm." (Source: "The Lives of the Primitive Fathers, Martyrs, and other Principal Saints", by Rev. Alban Butler, Vol. IV pp.
232-233, Edinburgh, 1799 A.D., Imprimatur) Note: also see the ancient (original) Liber Pontificalis historical account of the life of Pope & Martyr St. Caius, attributed to the Church Father & Doctor, St. Jerome. -ED
"By the Church is meant the Congregation of all who are baptized and profess the true faith under a *visible Head, that is, the Sovereign Pontiff.
*"visible Head" does not mean a pope is forbade from fleeing persecution via concealment - as Pope Caius chose for the majority of his reign (see above) - or as Pope Pius IX did during the
1848 masonic persecution in Rome, by fleeing the Roman Papal Palace clandestinely... making himself "invisible" by wearing a disguise, during his dangerous journey into exile, in Gaetia, Italy. See: tinyurl.com/Pexile -ED
"I say, the true faith, to exclude heretics who, though baptized, are separated from the Church.
"I say, under a visible head, to exclude schismatics, who do not obey the Pope, and on that account
easily pass from schism to heresy. St. Cyprian well says: 'Heresies and schisms
have no other origin than this—the refusal to obey the Priest of God, and the notion that there can be more than one priest at a time presiding over the Church, and more than one judge at a time filling the office of Vicar of Christ.'

From his classic
book: "THE CATHOLIC DOGMA"
New York, Cincinnati, and Chicago: BENZIGER BROTHERS
Printers to the Holy Apostolic See, Permissu Superiorum, 1888
"the Church shall be... as it was in the beginning, invisible, hidden in catacombs"

(In the Last Days...): "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, Archbishop of Westminster, 1861 A.D.
*"ubi Petrus,
ibi Ecclesia."
(Where Peter is, there is the Church.)

Ecclesiastical Approbation
In Today's Catholic World (TCWBLOG.com) carries the approbation in writing of the Holy See in exile. It faithfully
adheres to the rules for Catholic Journals mandated by Leo XIII in the Apostolic Constitution Officiorum ac Munerum, January 25, 1897 - so heavily re-stressed by Pius X in Pascendi Dominici Gregis, September 8, 1907.
