Here are some recent historical sources for the Catholic Church being the Church that JESUS CHRIST Himself established 2000 years ago. I hope this helps.
Roman Catholicism: The largest of the Christian denominations is the Roman Catholic church. As an institution it has existed since the 1st century AD...The name of the church is derived from its base in Rome and from a Greek term meaning "universal." The word Catholic refers to the wholeness of the church, and for many centuries the Roman church claimed to be the only true Christian denomination. (Compton's Interactive Encyclopedia © 1996)
Roman Catholicism: Christian church characterized by its uniform, highly developed doctoral and organizational structure that traces its history to the apostles of Jesus Christ in the 1st century C.E. (Marriam-Webster's Encyclopedia of World Religions © 1999, page 938 )
The history of the Roman Church, therefore, in relation to the ancient oriental churches, is in fact, the history of this claim to supremacy. The claim of supremacy on the part of the bishop of Rome rests on the belief that Christ conferred on the apostle Peter a 'primacy of jurisdiction;' that Peter fixed his see and died at Rome and thus, that the bishops of Rome, as successors of the apostle Peter, have succeeded to his preorgatives of supremacy. In this light, historians read the facts of the early history of the church---and they trace to this acknoledgment of the superiority of that see, the numerous references to Rome on matters of doctrine or discipline; the appeals from other churhces, even those of Alexandria, Antioch, and Constantinople; the depositions or nominations of bishops, examination and condemnation of heresies---of which the first five centuries, especially the 4th and 5th, present examples. . . In all the controversies on the Incarnation---the Arian, the Nestorian, the Eutychian, the Monothelite---not only was the orthodoxy of Rome never impeached, but she even supplied at every crisis a rallying point for the orthodox of every church.

The Church of Rome is the earliest of Christian organization; after three centuries of persecution, it was given freedom by the edict of Constantine and Licinius and acquired increased influence. Bishoprics were established in various parts of the empire, but the one at Rome remained supreme, and in time the title of Pope, or father originally borne by all the bishops indiscriminately, began to be restricted to the bishop of Rome.

The office of Pope was founded on the words of Christ: "And I say also unto thee, That thou art Peter [which means a rock], and upon this rock I will build my church; and the gates of hell shall not prevail against it" ( Matthew xvi, 18). The attention of every historian has been attracted by the endurance of the Papacy through centuries that have seen the downfall of every other European institution that existed when the Papacy arose, and of a number of others that have originated and fallen, while it continued t flourish. The Roman Catholic offers these facts as evidence that the Church is not merely a human institution, but that it is built "upon a rock," (The World Book Encyclopedia © 1940, Page 5730 Volume 13)
Historical Notes. The Holy Catholic Apostolic Roman Church recognizes the Bishop of Rome, the Pope, as the Vicar of Christ on this earth, and as the Head of the Church. It traces its origin from the naming of the Apostles Peter by Jesus as the chief of the Apostles . The authority of Peter as head of the Church is exercised by his successors as the Bishops of Rome. The doctrines of the Roman Catholic Church come from the faith given by Christ to his Apostles. (World Religions, By Benson Y. Landis, © 1957 Page 110)
At first the Christians were terribly persecuted, but gradually they spread the Christ’s radian spirit and teachings until they united many races, classes, and religious beliefs into a brotherhood which extended from Persia to the Atlantic Ocean. Later, this brotherhood spread to American, and Christianity became the prevailing religion of the Western Hemisphere. It has now ben taught in all countries.For nearly a thousand years the Christians remained practically one great community. Then the Greek Catholics broke away from the Roman Catholics.

(The Catholic) Church... traces an unbroken line of popes from St. Peter in the 1st century AD to the present occupant of the papal throne. During this nearly 2,000-year period there were more than 30 false popes, most notably during the late 14th and early 15th centuries. These men were merely claimants to the position. There have rarely been periods when a genuine pope was not ruling the church. In 1978 John Paul II became the 264th true pope.(Compton's Interactive Encyclopedia © 1996)

Roman Catholicism
The Founding: The apostles of Jesus Christ formed the beginnings of the Christian Church. They helped spread the Gospel and provided structure for the early Church. It is hard to differentiate the beginnings of the Roman Catholic church from that of the early Christian church. The apostle, Peter, also known as Simon, was of central importance. The Church was organized and presided over by Peter. According to the Scriptures, Matthew 16:13- 19, Christ said to Peter: "And I tell you, you are Peter, and on this rock I will build my church." In 313, the Roman Catholic Church was legally recognized by the Roman Emperor Constantine, and, in 380 it became the official religion of the Roman Empire.
