The incredible 2000 year longevity of the Holy Roman Catholic Church.

[Xavier]

English Protestant historian Thomas Macaulay, in spite of himself, is lost in admiration at the magnificent indestructibility of the Catholic Church over Her long and glorious history. If he had known the Sacred Scriptures a little better, he may have known this is that Kingdom of which it is written in the Prophets, from the Protestant Bible, "And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever." (Dan 2:44), the Keys of which Kingdom that same God of Heaven gave to St. Peter, Prince and head of the Apostles, Vicar of Jesus Christ, Rock and foundation of the Catholic Church. Most justly therefore does the First Vatican Council teach, https://www.ewtn.com/library/councils/v1.htm

"10. So that we could fulfill our duty of embracing the true faith and of persevering unwaveringly in it, God, through His only Begotten Son, founded the Church, and He endowed His institution with clear notes to the end that She might be recognized by all as the Guardian and Teacher of the revealed Word.

11. To the Catholic Church alone belong all those things, so many and so marvelous, which have been divinely ordained to make for the manifest credibility of the Christian Faith.

12. What is more, the Church Herself by reason of Her astonishing propagation, Her outstanding holiness and Her inexhaustible fertility in every kind of goodness, by Her Catholic unity and Her unconquerable stability, is a kind of great and perpetual motive of credibility and an incontrovertible evidence of Her own divine mission.

13. So it comes about that, like a standard lifted up for the nations [22, ref Isa 11:12], She both invites to Herself those who have not yet believed, and likewise assures Her sons and daughters that the Faith they profess rests on the firmest of foundations."

Thomas Babington Macaulay wrote, "There is not, and there never was on this earth, a work of human policy so well deserving of examination as the Roman Catholic Church. The history of that Church joins together the two great ages of human civilisation. No other institution is left standing which carries the mind back to the times when the smoke of sacrifice rose from the Pantheon, and when camelopards and tigers bounded in the Flavian amphitheatre. The proudest royal houses are but of yesterday, when compared with the line of the Supreme Pontiffs. That line we trace back in an unbroken series, from the Pope who crowned Napoleon in the nineteenth century to the Pope who crowned Pepin in the eighth; and far beyond the time of Pepin the august dynasty extends, till it is lost in the twilight of fable. The republic of Venice came next in antiquity. But the republic of Venice was modern when compared with the Papacy; and the republic of Venice is gone, and the Papacy remains. The Papacy remains, not in decay, not a mere antique, but full of life and youthful vigour. The Catholic Church is still sending forth to the farthest ends of the world missionaries as zealous as those who landed in Kent with Augustin, and still confronting hostile kings with the same spirit with which she confronted Attila. The number of her children is greater than in any former age. Her acquisitions in the New World have more than compensated for what she has lost in the Old. Her spiritual ascendency extends over the vast countries which lie between the plains of the Missouri and Cape Horn, countries which a century hence, may not improbably contain a population as large as that which now inhabits Europe. The members of her communion are certainly not fewer than a hundred and fifty millions; and it will be difficult to show that all other Christian sects united amount to a hundred and twenty millions. Nor do we see any sign which indicates that the term of her long dominion is approaching. She saw the commencement of all the governments and of all the ecclesiastical establishments that now exist in the world; and we feel no assurance that she is not destined to see the end of them all. She was great and respected before the Saxon had set foot on Britain, before the Frank had passed the Rhine, when Grecian eloquence still flourished at Antioch, when idols were still worshipped in the temple of Mecca. And she may still exist in undiminished vigour when some traveller from New Zealand shall, in the midst of a vast solitude, take his stand on a broken arch of London Bridge to sketch the ruins of St. Paul's."
